The present system, in general relates to one way clutch assembly, and in particular relates to the leg type one way clutch assembly containing a blind cam profiled race and a cylindrical profiled race.
Background of the invention
Every system that requires transmission of torque from one torque generating device to another torque generating device in one direction only, uses one way clutch. One way clutch assembly is used in any system or application where it is required that torque should be transmitted in one direction only, and not in reverse direction. There are 2 modes of operation for the one way clutch assembly, i.e. locking and free-wheeling or over-running. The one way clutch assembly can be classified into four types which are (i) Locking element, (ii) Component containing cam profiled race, (iii) Component containing cylindrical profiled race, and (iv) Cam profile type. Furthermore, locking element can be roller type, sprag type, cam type and pawl type. The component containing cam profiled race is of two types - (a) Outer cam is the cam profile which is formed on the inner diameter surface of the component, and (b) Inner cam is the cam profile which is formed on the outer diameter surface of the component. The Component containing cylindrical profiled race is also of two types - (a) Outer race in which the cylindrical profile is formed on the inner diameter surface of the component, and (b) Inner race in which the cylindrical profile is formed on the outer diameter surface

of the component. And the cam profile type one way clutch assembly can be of leg type or hook type.
The conventional technology of the one way clutch assembly comprises mainly of locking elements, cam profiled race, cylindrical profiled race, and a thin plate which is permanently joined to the through machined/formed cam profiled race. At high speed of rotation of the one way clutch assembly, there is tendency for roller to apply cyclic load on the thin flat plate. This results in deformation of the plate resulting in loss of partial functionality of the assembly while reducing the service life significantly. Heat is generated due to the friction between roller and cylindrical profiled inner race. The thin plate which supports the roller and the compression spring as in existing design of one way clutch assembly is less resistant to thermal deformation. To overcome the aforesaid limitations in the existing technology of one way clutch assembly, the present invention proposed leg type one way clutch assembly containing a blind cam profiled race and a cylindrical profiled race, eliminating the use of thin flat plate that is permanently joined with the cam profiled race, thereby reducing the number of parts in the assembly.
Objective of the invention
The prime objective of the present invention is to provide a leg type one way clutch assembly comprising of a cam profiled race with blind cam profile, a cylindrical profile inner race, locking elements and compression springs in which the cam profiled race with blind cam profile is wedging the locking elements when transferring torque and providing support to the locking elements and to the compression springs.

Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile, in which the blind cam profiled race combines the function of through cam profiled race, i.e. wedging the locking element when transferring torque, and the thin flat plate that is permanently joined with the cam profiled race, for providing support to the locking element and the compression spring before assembly with the cylindrical profiled race.
Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile eliminates the use of thin flat plate that is permanently joined with the cam profiled race, thereby reducing the number of parts in the assembly.
Yet another objective of the present invention is to provide a leg type one way dutch assembly containing cam profiled race with blind cam profile which eliminates the assembly process of permanently joining the thin flat plate to the cam profiled race.
Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile in which the surface in contact with the locking element and perpendicular to the cam profile, has higher surface hardness than the thin flat plate that is permanently joined to the cam profiled race with through cam profile.
Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile in which the surface in

contact with the locking element and perpendicular to the cam profile, has improved geometrical tolerance than the thin flat plate that is permanently joined to the cam profiled race with through cam profile.
Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile in which the surface in contact with the locking element and perpendicular to the cam profile, has better resistance to the cyclic load applied by roller during high rotational speed of the assembly than the thin flat plate that is permanently joined to the cam profiled race with through cam profile.
Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile in which the surface in contact with the locking element and perpendicular to the cam profile, has better resistance against thermal deformation than the thin flat plate that is permanently joined to the cam profiled race with through cam profile.
Yet another objective of the present invention is to provide a leg type one way clutch assembly containing cam profiled race with blind cam profile which has improved service life than the leg type one way clutch assembly containing cam profiled race with through profile.
Yet another objective of the present invention is to propose a leg type one way clutch assembly containing cam profiled race with blind cam profile which provides better

performance at high speed of rotation of one way clutch assembly, better resistance to deformation under increased heat due to friction, improved service life and economical over existing technology of one way clutch assembly with through profile.

The following is a detailed description of exemplary embodiments to illustrate the principles of the invention. The embodiments are provided to illustrate aspects of the invention, but the invention is not limited to any embodiment. The scope of the invention encompasses numerous alternatives, modifications and equivalent; it is limited only by the claims.

Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. However, the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.
The illustrative and preferred embodiments in accordance with the present invention will now be described with reference to the accompanying drawings.
Figure-1 is showing a usual arrangement of the existing design of the one way clutch assembly. In figure-1, the conventional one way clutch assembly is depicted with the arrangement of the components which are cam profiled outer race (1), cylindrical profiled inner race (2), locking element (3), compression spring (4) and a thin flat component (5). The locking or free-wheeling mode is based on the.rotational speed difference between cylindrical profiled inner race (2) and cam profiled outer race (1), and on the direction of rotation. When both components - cam profiled outer race (1) and cylindrical profiled inner race (2), rotate in the same direction, the general principle is that the profiled race component which is at higher rotational speed becomes the driver and transmitter of torque. In the arrangement shown in Figure - 1, all possible scenarios are as described below tables-

Direction
of rotation Cam profiled outer race Cylindrical profiled inner race
Clock wise Rotational Speed >inner race, Locking Rotational Speed >outer race, free-wheel
Counter clockwise Rotational Speed > inner race, free-wheel Rotational Speed > outer race, Locking

Table - 1 is showing the Operation mode scenarios when outer race and inner race are rotating in same direction
When both components rotate in opposite direction, the following condition holds true -

Operation
mode Cam profiled outer race Cylindrical profiled inner race
Free-wheel Direction of rotation - Counter clockwise Direction of rotation - Clock wise
Locking Direction of rotation - Clock wise Direction of rotation - Counter clockwise
Table - 2 is showing the Operation mode scenarios when outer race and inner race are rotating in opposite direction.
The tool used to manufacture the cam profile on outer race (1) removes/displaces the material to a specified depth, which is more than the overall thickness of the cam profiled race, and therefore the cam profile in the finished outer race is through machined/formed.
A thin flat component (5) is required to be permanently joined to the through machined/formed outer race (1) in order to provide support for the locking element (3) and/or compression spring (4).
Locking mode :As shown in figure - 1, the cam profiled outer cam (1)along with the locking element - roller (3), compression spring (4), and cylindrical profiled inner race (2) are arranged in such a manner that the roller (3) is in contact with both the cam profiled outer race (1) and cylindrical profiled inner race (2). The function of compression spring (4) vis-a-vis one of the embodiments of existing design as shown in figure - 1 is three-fold -

• Hold the roller (3) in position before assembly with the inner race (2)
• Keep the roller (3) in locking position after assembly with the inner race (2)
• Allow roller (3) to disengage with the inner race (2) when centrifugal force is more than the spring force.
The roller (3) gets wedged between the cam profiled outer race (1) and cylindrical profiled inner race (2) during locking mode, and due to contact stress generated between the cylindrical profiled inner race (2) and the roller (3), the torque gets transmitted from inner race to outer race or vice versa.
Free-wheeling mode: The convex surface of the roller (3) is always in contact with the concave surface of the cam profiled outer race (1). A centrifugal force acts on the roller (3) as the rotational speed of outer race increases (1), and as detailed in Table - 1 and Table - 2, at certain value of the rotational speed, the centrifugal force overcomes the spring force exerted by the compression spring (4), and the roller (3) disengages with the inner race (2).
The preferred embodiment of the present invention is shown in Figure-2 herein. The Figure-2 depicts the proposed leg type one way clutch assembly which comprisesof a cam profiled race with blind cam profile (6), a cylindrical profile inner race (2), locking elements (3) and compression springs (4), wherein the blind cam profiled race (6), i.e. the tool used to form the profile removes/displaces material to a specified depth, without breaking through to the other side of the cam profiled race (1), combines the function of a flat thin plate (5) that is permanently joined with the through machined/formed cam profiled race (1)in one single component, resulting in the reduction of the number of
9

parts in the assembly and elimination of assembly process of permanently joining the
flat thin plate (5) to the cam profiled race (1). The locking elements (3) are rollers, cams,
sprags and pawls.
The leg type one way clutch assembly provided by the current invention, is containing a
cam profiled race with blind cam profile, in which the blind cam profiled race (6)
combines the function of through cam profiled race (1), i.e. wedging the locking element
(3) when transferring torque, and the thin flat plate (5) that is permanently joined with
the cam profiled race (1), for providing support to the locking element (3) and the
compression spring (4) before assembly with the cylindrical profiled race (2).
The one way clutch assembly provided by the current invention, wherein the blind cam
profiled race (6), i.e. the tool used to form the profile removes/displaces material to a
specified depth, without breaking through to the other side of the cam profiled race,
combines the function of a flat thin plate (5) that is permanently joined with the through
machined/formed cam profiled race (1) in one single component.
The leg type one way clutch assembly according to the present invention also provides
better performance than the existing one way clutch assembly at high speed of rotation
of the one way clutch assembly, and better resistance to deformation under increased
heat due to friction.
At high speed of rotation of the one way clutch assembly, there is tendency for roller to
apply cyclic load on the thin flat plate. This results in deformation of the plate resulting in
loss of partial functionality of the assembly while reducing the service life significantly.
Heat is generated due to the friction between roller and cylindrical profiled inner race.
The thin plate which supports the roller and the compression spring (5), as in existing
10

clutch assembly, is less resistant to thermal deformation than the solid metal as per the
proposed design.
Moreover, the cam profiled outer race is case carburized and shot blasted, as a result of
which, the surface finish and geometrical control parameters of the cam profiled outer
race with blind profile (6), i.e. where cam profile is formed to a specified depth, and not
through to the other side of the outer race, are improved. Therefore, the service life of
the said assembly is improved significantly over the one way clutch assembly with
through profile.
The leg type one way clutch assembly according to the present invention containing
cam profiled race with blind cam profile (6), wherein the surface in contact with the
locking element (3) and perpendicular to the cam profile (6), has higher surface
hardness than the thin flat plate (5) that is permanently joined to the cam profiled race
with through cam profile (1).
The leg type one way clutch assembly according to the present invention containing
cam profiled race with blind cam profile (6), wherein the surface in contact with the
locking element (3) and perpendicular to the cam profile (6), has improved geometrical
tolerance than the thin flat plate (5) that is permanently joined to the cam profiled race
with through cam profile (1).
The leg type one way clutch assembly according to the present invention containing
cam profiled race with blind cam profile wherein the surface in contact with the locking
element (3) and perpendicular to the cam profile (6), has better resistance to the cyclic
load applied by roller (3) during high rotational speed of the assembly than the thin flat
plate (5) that is permanently joined to the cam profiled race with through cam profile (1).

The leg type one way clutch assembly according to the present invention containing cam profiled race with blind cam profile (6) has improved service life than the conventional leg type one way clutch assembly containing cam profiled race with through profile.
Although preferred embodiments of the invention has been illustrated and described, it will at once be apparent to those skilled in the art that the invention includes advantages and features over and beyond the specific illustrated construction. Accordingly it is intended that the scope of the invention be limited solely by the scope of the hereinafter appended claims, and not by the foregoing specification, when interpreted in light of the relevant prior art.
