Description:FIELD OF INVENTION
Embodiments of the present disclosure relate to the field of mechanical motion conversion systems, and more particularly, an assembly for generating rotary linear reciprocating motion and a method thereof.
BACKGROUND
A slider-crank mechanism is a mechanical system designed to convert rotary motion into linear motion or vice versa. It is a four-bar linkage consisting of a crank, a slider, and a connecting rod. This mechanism is one of the most widely used in pumps and internal combustion engines. However, it comes with several challenges. One significant drawback is the presence of numerous moving parts, which increases the complexity and requires additional maintenance. In engines, multiple cylinders are required to balance power stroke fluctuations, adding further challenges. Additionally, unwanted friction and noise are common, reducing overall efficiency. Vibrations also shorten the lifespan of components and machinery. To address these issues, extra measures such as balancing, lubrication, and other remedies are necessary, which in turn raises the overall cost of the machinery.
However, there are some alternative designs, such as conventional rotary engines and positive displacement pumps like Wankel engines, gear pumps, and vane pumps, which offer some solutions but come with a few limitations. One major concern with the alternative design is ensuring proper sealing of the chamber. During compression or expansion, fluid may leak from one side to another due to imperfect seals at the tips of rotors or vanes. Furthermore, the alternative designs are inherently complex, involving internal gears and springs to control the motion of parts, which makes them less cost-effective and less practical. Additionally, lubricating the tips of vanes or rotors is inefficient, as these components come into direct contact with the working fluid, leading to high lubricant consumption. Rotary engine designs also feature narrow combustion chambers, which increase the surface area-to-volume ratio, resulting in greater heat loss and reduced efficiency.
Hence, there is a need for an assembly for generating rotary linear reciprocating motion and a method thereof which addresses the aforementioned issue(s).
OBJECTIVES OF THE INVENTION
The primary objective of the invention is to develop an assembly for generating rotary linear reciprocating motion with fewer moving parts, reducing complexity and maintenance.
Another objective of the invention is to provide a mechanism that generates the rotary linear reciprocating motion with fewer moving parts, primarily for use in rotary engines and rotary positive displacement pumps.

FIG. 1 is a schematic representation of an assembly (100) for generating rotary linear reciprocating motion in accordance with an embodiment of the present disclosure. The assembly (100) is adapted to convert rotational motion into rotary linear reciprocating motion. The assembly (100) is used for specific applications including but is not limited to positive displacement pumping, internal combustion engine and the like.
The assembly (100) includes an oval shaped cylindrical housing (105) with an internal space adapted to accommodate a plurality of components. The oval shaped cylindrical housing (105) is a fixed part of the assembly (100) that provides structural support and guiding the motion of the plurality of components. The shape of the oval shaped cylindrical housing (105) is important for ensuring a sinusoidal path of the rotary linear reciprocating motion. The oval-shaped cylindrical housing is constructed from durable, heat-resistant materials, such as cast aluminum, steel alloys, and the like. The plurality of components includes a rotating shaft (110), a rotating slider (115), an intake port (125), an exhaust port (130), a spark plug port (135), and a sliding sheet (120).
The rotating shaft (110) mounted eccentrically on a center line of the oval shaped cylindrical housing (105).
The plurality of components includes a rotating slider (115) positioned mounted on the rotating shaft (110) and slides within the internal space of the oval-shaped cylindrical housing. The rotating slider (115) is adapted to divide the internal space of the oval shaped cylindrical housing (105) into a first chamber and a second chamber. The rotating slider (115) slides based on the motion of the rotating shaft (110), which causes the rotating slider (115) to follow the sinusoidal motion. The sinusoidal motion occurs because of the positioning of the rotating shaft (110), which causes the rotating slider (115) to move in a periodic manner. The rotating slider (115)’s movement alternately increases and decreases the volume of the first chamber and the second chamber.
Further, the rotating slider (115) is adapted to follow a sinusoidal sliding path in response to rotation of the rotating shaft (110), thereby alternately modulating volumes of the first chamber and the second chamber.
The rotating shaft (110) is adapted to rotate continuously for providing continuous rotary motion to the rotating slider (115).
The plurality of components includes an intake port (125), an exhaust port (130), and a spark plug port (135) positioned within the oval shaped cylindrical housing (105). The intake port (125) and the exhaust port (130) are adapted to regulate flow of fluid into and out of the first chamber and the second chamber based on the rotation of the rotating shaft (110). The fluid is at least one of fuel, air, a fuel-air mixture, and the like.
The plurality of components is a sliding sheet (120) positioned within the rotating slider (115). The sliding sheet (120) is adapted to provide a sealing interface between the first chamber and the second chamber to minimize fluid leakage during operation, ensuring optimal compression and operational efficiency.
In one embodiment, the sliding sheet (120) is a metallic sheet within the rotating slider (115). The rotation of the sliding sheet (120) is guided to follow the motion of the rotating slider (115). The edges of the rotating slider (115) and the sliding sheet (120) remain intact with the oval shaped cylindrical housing (105).
The operation of the assembly includes a continuous cycle of intake, compression, combustion, and exhaust. During the intake, the rotating slider (115) moves such that the volume of the first chamber increases, creating a vacuum and allowing fluid to enter the first chamber through the intake port (125).
During compression, the rotating slider (115) reduces the volume of the first chamber, thereby compressing the fluid inside.
During the combustion, the compressed fluid undergoes expansion due to ignition within the first chamber, causing expansion, and generate rotational energy which is transmitted to the rotating shaft (110) to sustain the continuous rotation of the rotating shaft (110).
During the exhaust, the rotating slider (115) reduces the volume of the first chamber expelling burnt gases through the exhaust port (130) while the second chamber alternates through the intake, compression, combustion, and exhaust to enable continuous operation of the assembly.
It must be noted that the power output of the assembly is one power cycle per two rotations of the rotating shaft (110).
Additionally, the plurality of components comprises a lube chamber (150) designed inside the rotating slider and connected to an external lube source. The Lube chamber (150) is adapted to alternatively increase and decrease in volume. The lube chamber’s (150) boundaries consist of the sliding sheet, the rotating shaft and the cylindrical housing. It does not come into direct contact with the working fluid of the system, reducing its dissolution in the working fluid and emissions after combustion in the case of an internal combustion engine.
It must be noted that the assembly (100) includes a mechanism for generating rotary linear reciprocating motion. The mechanism includes a rotating shaft (110) mounted eccentrically within an oval-shaped cylindrical housing (105). The rotating shaft (110) rotates continuously, driving a rotating slider (115) constrained by the oval-shaped cylindrical housing (105) to follow a sinusoidal sliding path. The rotating slider’s (115) motion alternately increases and decreases the volume of a first chamber and a second chamber of the oval shaped cylindrical housing (105), enabling a continuous modulation of chamber volumes through intake, compression, combustion, and exhaust phases to facilitate continuous operation of the assembly (100). The rotating slider (115) exhibits a synchronized rotational and reciprocating linear displacements, thereby generating rotary linear reciprocating motion.
FIG. 2(a), FIG. 2(b), FIG. 2(c) and FIG. 2(d) are schematic representations of an oval-shaped cylindrical housing, a rotating shaft, a rotating slider, and a sliding sheet respectively of FIG. 1, in accordance with an embodiment of the present disclosure. FIG. 2(a) illustrates the oval shaped cylindrical housing (105), which forms a fixed outer structure of the assembly. The oval shaped cylindrical housing (105) includes an internal space to accommodate a plurality of components and guide their motion. The plurality of components includes rotating shaft, rotating slider, and sliding sheet. FIG. 2(b) shows the rotating shaft (110), which is positioned eccentrically within the oval shaped cylindrical housing. The rotating shaft (110) is adapted to rotate continuously, driving the motion of other components in the assembly. FIG. 2(c) shows the rotating slider (115), which divides the internal space of the housing into two chambers. The rotating slider (115) is responsible for modulating the first chamber and a second chamber volumes in response to the rotation of the rotating shaft. FIG. 2(d) illustrates the sliding sheet (120), which is positioned within the rotating slider. The sliding sheet (120) serves as a sealing interface between the two chambers, minimizing fluid leakage during operation.
FIG. 3(a), FIG. 3(b), FIG. 3(c), FIG. 3(d), FIG. 3(e), FIG. 3(f), FIG. 3(g), and FIG. 3(h) represent the operation of the assembly (100) for generating rotary linear reciprocating motion of FIG.1 in accordance with an embodiment of the present disclosure. FIG. 3(a) shows an intake port (125) opening, allowing fluid to enter a first chamber (140) of the oval-shaped cylindrical housing.
FIG. 3(b) depicts the first chamber being filled with fluid while the intake port (125) remains open.
FIG. 3(c) illustrates that, during the continuous rotation of the rotating shaft (110), a second chamber (145) begins to fill with fluid, while the fluid in the first chamber (140) undergoes compression.
FIG. 3(d) demonstrates that a spark is generated, igniting the compressed fluid in the first chamber (140). The combustion causes expansion within the first chamber (140), generating power. The expansion rotates the rotating slider (115), which in turn rotates the rotating shaft (110). Simultaneously, the second chamber (145) is filled with fluid.
FIG. 3(e) shows the continued expansion of the combusted fluid in the first chamber (140) continues, generating force that rotates the slider and the shaft. Simultaneously, the fluid in the second chamber is compressed, and a spark ignites the compressed fluid in the second chamber initiating combustion.
FIG. 3(f) depicts combustion occurring in the second chamber (145), causing expansion, which pushes the slider and provides power to the rotating shaft (110). At the same time, an exhaust port (130) opens, expelling the burnt gases from the first chamber (140).
FIG. 3(g) shows the cycle restarting as the intake port (125) opens again, allowing fluid to enter the first chamber (140).
FIG. 3(h) illustrates the integration of a lube chamber (150) in the assembly (100). The lube chamber (150)’s volume alternately increases and decreases, drawing lubricant from an external source when a vacuum is created. The lubricant is distributed to the tips of the slider and sliding sheet (120) during their sliding and rotating motion.
FIG. 4 is a schematic representation of the mathematical calculations of an assembly for generating rotary linear reciprocating motion in accordance with an embodiment of the present disclosure. As shown in FIG. 4, the assembly includes a rotating slider of length 2l, rotating around a point (a, b). During rotation, the rotating slider moves downward in a sinusoidal pattern. When the rotating slider is parallel to y- axis, it is shifted downwards by some eccentricity e, where e less than l.
At any angle ?:
slider length above the x axis = l- e sin ?
slider length below x axis = l – e sin ? (as sin ? will be negative the length increases).
Hence, the motion making an oval shape during rotation, lets determine the profile formed by the slider's edges to ensure continuous contact between the housing and the slider edges.
If the rotating slider is shifting in a sinusoidal way, at some angle ? the length of slider from the rotational point is l-e sin ?.
Parametric coordinates for the housing are:
x = a+ (l- e sin ?) cos ? and,
y =b+ (l- e sin ?) sin ?
If the rotating slider is rotating around origin, then (a, b) = (0,0)
Then, x = (l- e sin ?) cos ?………………… (Equation 1)
y = (l- e sin ?) sin ?…………………...(Equation 2)
Using Pythagoras theorem,
x^2+ y^2=?(l-e sin ?)?^2………………….. (Equation 3)
Slope of the slider at any point is:,
tan ? = y/x, sin ? = tan ? / ?1+ ?tan ?^2 ?)?^(1/2)
sin ? = y/v(x^2+ y^2) {Putting y/x in place of tan ?)
x^2+ y^2=?(l-e y/v(x^2+ y^2))?^2 ……………(Equation 4)
This results in the equation for the oval-shaped housing, where l represents half the length of the slider, and e is the eccentricity of the rotating point of the slider from the center point of the oval shaped cylindrical housing. For higher value of e, the compression ratio increases. For diesel engines, higher compression ratios are required.
FIG. 5(a) and FIG. 5(b) are representations of an exemplary embodiment of a system and a kinematic analysis for generating rotary linear reciprocating motion of FIG. 1 in accordance with an embodiment of the present disclosure. mechanism includes a rotating shaft (110) mounted eccentrically within an oval-shaped cylindrical housing (105). The rotating shaft (110) rotates continuously, driving a rotating slider (115) constrained by the oval-shaped cylindrical housing (105) to follow a sinusoidal sliding path. The rotating slider’s (115) motion alternately increases and decreases the volume of a first chamber and a second chamber of the oval shaped cylindrical housing (105), enabling a continuous modulation of chamber volumes through intake, compression, combustion, and exhaust phases to facilitate continuous operation of the assembly (100). The rotating slider (115) exhibits a synchronized rotational and reciprocating linear displacements, thereby generating rotary linear reciprocating motion.
Let’s consider the kinematic analysis of the mechanism;
Degree of Freedom (F) for the mechanism is calculated as:
F=3(n-1)-2j-h
Where n is the number of links, j is the number of lower pairs (joints), and h is the number of higher pairs.
For the mechanism:
Number of links: n = 3
Higher pair (170): h = 1 (between rotating slider (115) and the oval-shaped cylindrical housing (105))
Number of joints: j = 2 (revolute pair (175) and sliding pair (180)).
Therefore, the degree of Freedom is:
F=3(3-1)-2·2-1=1
F = 3(2)-2·2-1
F= 1
The result indicates that the mechanism has one degree of freedom, meaning a single input motion controls the entire assembly. For instance, in a positive displacement pump, where the input is the rotating shaft, and in rotary engines, where the input is the high-pressure force on the slider during gas expansion, the mechanism have been applied.

The method (200) includes regulating, by an intake port, an exhaust port, and a spark plug port flow of fluid into and out of the first chamber and the second chamber based on the rotation of the rotating shaft in step 225.
The method (200) includes providing, by a sliding sheet, a sealing interface between the first chamber and the second chamber to minimize fluid leakage during operation.

During compression, the rotating slider reduces the volume of the first chamber, thereby, compressing the fluid. During the combustion, the compressed fluid undergoes expansion due to ignition within the first chamber, causing expansion, and generate rotational energy which is transmitted to the rotating shaft to sustain the continuous rotation of the rotating shaft. During the exhaust, the rotating slider reduces the volume of the first chamber expelling burnt gases through the exhaust port while the second chamber alternates through the intake, compression, combustion, and exhaust to enable continuous operation of the assembly in step 225.
