TITLE OF THE INVENTION
A collaborative protective housing for flywheel and brakes
APPLICANTS :
Crompton Greaves Limited, CG House, Dr Annie Besant Road, Worli, Mumbai 400 030, Maharashtra, India, an Indian Company
INVENTOR (S):
Mistry Dipakrai Kukibhai and Desoria Prateek Kumar; both are of Crompton Greaves Ltd, Machine (M7) Division, D-5, Industrial Area, MPAKVN, Mandideep - 462046, Madhya Pradesh,India; both Indian Nationals.
PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the nature of this invention and the manner in which it is to be performed:

Field of the Invention:
This invention relates to the field of mechanical engineering.
Particularly, this invention relates to generators.
Still particularly, this invention relates to housings for brakes and flywheel of a generator.
More particularly, this invention relates to a collaborative protective housing for flywheel and brakes.
Background of the Invention:
In electricity generation, an electric generator is a device that converts mechanical energy to electrical energy.
Synchronous Generators are the primary source of all electrical energy and commonly used to convert the mechanical power output of steam turbines, gas turbines, reciprocating engines, hydro turbines and wind turbines into electrical power for the grid. They are known as synchronous generators because they operate at synchronous speed. The constant magnetic field of the rotor is produced by the persistent magnetic field of a rotor permanent magnet assembly or by controlling direct current to a rotor field winding (i.e. electromagnet) fed through a slip-ring assembly or a brushless means.

A flywheel is a mechanical device with a significant moment of inertia used as a storage device for rotational energy. The use of flywheel in a generator reduces speed fluctuations of the generator.
This flywheel includes braking means or brakes to reduce/stop generator motion. Hydraulic brakes are used to reduce the rotating motion of rotor by applying brake on flywheel in Generator. These brakes may, preferably, be hydraulic disc brakes. Regenerative braking also increases efficiency.
Both, the flywheel as well as the brakes, require a protective housing.
Prior Art:
In accordance with the prior art, hydraulic disc brakes protection guard is not integrated with Flywheel protection guard.
These Hydraulic brakes were typically mounted outside of Flywheel guard which requires additional material to cover the brakes and it also occupies additional space. Separate guards for Flywheel and brakes are used.
This, therefore, increases material cost and space.
US2008047391 discloses an efficient auxiliary power supply. It mentions the arrangement of flywheel and brakes. ("System may include brakes which arrest the rotating motion of the disks the brakes may be respectively affixed proximate to the end of the slots at the rim of the flywheel"). However, there is a need for a collaborative housing which results in space and cost saving.

Objects of the Invention:
An object of the invention is to provide a relatively inexpensive protective housing for flywheel and brake assembly.
Another object of the invention is to provide a relatively space saving protective housing for flywheel and brake assembly.
Yet another object of the invention is to provide a collaborative protective housing for flywheel and brake assembly.
Summary of the Invention:
According to this invention, there is provided a collaborative protective housing for flywheel and brakes, said housing comprises:
a. Flywheel protective housing adapted to protect a flywheel, its shape
corresponding to the shape of said flywheel; and
b. brake housing adapted to be partially ensconced within said flywheel
protective housing through its operative lateral edge, its shape corresponding
to the shape of the brake assembly;
thereby providing a reduced arm length of the brakes and a lesser span of the housing.
Typically, said housing includes a hole for shaft-mounting and for said shaft to pass through said housing.

Typically, said brake housing is disposed on front side edge and back side edge of said flywheel within said flywheel housing.
Brief Description of the Accompanying Drawings:
Figure 1 illustrates a schematic isometric view of the protective housing for flywheel and protective housing for brakes;
Figure 2 illustrates a schematic front view of Figure 1;
Figure 3a illustrates a schematic side view of the protective housing for brake of Figure 1;
Figure 3b illustrates a schematic isometric view of the protective housing for brake of Figure 1; and
Figure 4 illustrates a schematic isometric view of the protective housing for flywheel of Figure 1.
The invention will now be described in relation to the accompanying drawings, in which:
Figure 5 illustrates a schematic isometric view of a collaborative protective housing for flywheel and brakes;
Figure 6 illustrates a schematic front view of Figure 5; and
Figure 7 illustrates a schematic front view of Figure 5.

Detailed Description of the Accompanying Drawings:
Figure 1 illustrates a schematic isometric view of the protective housing for flywheel and protective housing for brakes; Figure 2 illustrates a schematic front view of Figure 1; Figure 3a illustrates a schematic side view of the protective housing for brake of Figure 1; Figure 3b illustrates a schematic isometric view of the protective housing for brake of Figure 1; and Figure 4 illustrates a schematic isometric view of the protective housing for flywheel of Figure 1.
The prior art flywheel protective housing (12) was a semicircular housing with a rectangular extension at its flat end. This serves as a protective cover for the flywheel. The prior art has a distinct attached brake protective housing (14). The brake housing and flywheel housing are attached at a common side seam such that they occupy respective spaces as shown in the drawings.
According to this invention, there is provided a collaborative protective housing (100) for flywheel and brakes.
Figure 5 illustrates a schematic isometric view of a collaborative protective housing for flywheel and brakes; Figure 6 illustrates a schematic front view of Figure 5; and Figure 7 illustrates a schematic front view of Figure 5.
In accordance with an embodiment of this invention, there is provided a flywheel protective housing (22) adapted to protect a flywheel. Its shape corresponds to the shape of the flywheel.

In accordance with another embodiment of this invention, there is provided a brake housing (24) adapted to be partially ensconced within said flywheel protective housing through its operative lateral edge. The shape of this housing corresponds to the shape of the brake assembly.
Cumulatively, this collaborative housing is shaft (26) mounted.
Due to this collaborative housing, the length of the arm of brakes is reduced as the brakes are held relatively closer to the flywheel. Space saving occurs as the collaborative housing has a lesser length than the prior art housing. Due to shorter arm of the brakes, the brakes work relatively more efficiently (and in a quicker manner).
While this detailed description has disclosed certain specific embodiments of the present invention for illustrative purposes, various modifications will be apparent to those skilled in the art which do not constitute departures from the spirit and scope of the invention as defined in the following claims, and it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.

We claim,
1. A collaborative protective housing for flywheel and brakes, said housing
comprising:
a. flywheel protective housing adapted to protect a flywheel, its shape
corresponding to the shape of said flywheel; and
b. brake housing adapted to be partially ensconced within said flywheel
protective housing through its operative lateral edge, its shape corresponding
to the shape of the brake assembly;
thereby providing a reduced arm length of the brakes and a lesser span of the housing.
2. A collaborative protective housing as claimed in claim 1 wherein, said housing includes a hole for shaft-mounting and for said shaft to pass through said housing.
3. A collaborative protective housing as claimed in claim 1 wherein, said brake housing is disposed on front side edge and back side edge of said flywheel within said flywheel housing.
