Abstract
Abstract A vibration dissipation mount which permits the mounting of a motor, generator, or the like such that the rotatable shaft thereof passes through the mount and the mount permits the dissipation of self-induced and otherwise induced vibrations wherein the mount comprises a pair of plates having complementary concave and convex surfaces, a semi-resilient material being disposed therebetween.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A vibration dissipation mount for a flywheel assembly comprising: a flywheel; a rotating shaft connected at a first end to said flywheel; a flywheel chamber which encloses said flywheel and into which said rotating shaft passes; a motor connected to a second end of said rotating shaft for driving said flywheel; a pair of complementary plates, one of said plates having a convex surface, the other of said plates having a complementary concave surface, each of said plates having an aperture extending through said complementary surfaces thereof, said apertures being dimensioned to accommodate there through and to permit free rotation of said rotating shaft when said plates are disposed in complementary relationship, one of said plates being affixed to said motor, the other of said paltes being affixed to said flywheel chamber; and a cushioning means being disposed between said plates.
Claim 2
Dependent Claim
141 words
A vibration dissipation mount for a flywheel assembly comprising: a flywheel; a rotating shaft connected at a first end to said flywheel; a flywheel chamber which encloses said flywheel and into which said rotating shaft passes; a motor connected to a second end of said rotating shaft for driving said flywheel; a pair of complementary plates, one of said plates having a convex surface, the other of said plates having a complementary concave surface, each of said plates having an aperture extending through said complementary surfaces thereof, said apertures being dimensioned to accommodate there through and to permit free rotation of said rotating shaft when said plates are disposed in complementary relationship, one of said plates being affixed to said motor, the other of said paltes being affixed to said flywheel chamber; and a cushioning means being disposed between said plates.
Claim 3
Dependent Claim
70 words
A vibration dissipation mount in accordance with claim 1, wherein said concave surface has end edges defining a pair of spaced apart planes, said concave and convex surfaces and said cushioning means being dimensioned such that when said concave and convex surfaces are disposed in said complementary relationship with said cushioning means therebetween, at least a portion of said convex surface falls in a plane intermediate said spaced apart planes.
Claim 4
Dependent Claim
37 words
A vibration dissipation mount in accordance with claim 2, wherein said convex surface has the end edge thereof adjacent to said cushioning means falling in a plane intermediate said spaced apart planes defined by said concave surface.
Claim 5
Dependent Claim
22 words
A vibration dissipation mount in accordance with claim 1, wherein said convex and concave surfaces are each shaped as a truncated cone.
Claim 6
Dependent Claim
84 words
A vibration dissipation mount in accordance with claim 4, wherein said concave surface shaped as a truncated cone has the end edges of said truncated cone define a pair of spaced apart planes, said concave and convex surfaces and said cushioning means being dimensioned such that when said concave and convex surfaces are disposed in said complementary relationship with said cushioning means therebetween, the end edge of said convex surface adjacent to said cushioning means falls in a plane intermediate said spaced apart planes.
Claim 7
Dependent Claim
35 words
A vibration dissipation mount in accordance with claim 4, wherein said plate having said concave surface is fixedly secured to said motor, said plate having said convex surface being fixedly secured to said flywheel chamber.
Claim 8
Dependent Claim
27 words
A vibration dissipation mount in accordance with claim 1, wherein said cushioning means comprises a semi-resilient material configured to be disposed between said pair of complementary plates.
Claim 9
Dependent Claim
38 words
A vibration dissipation mount in accordance with claim 7, wherein said semi-resilient material is annular in shape and has a hole therethrough, said hole aligning with said apertures disposed in said pair of complementary plates when disposed therebetween.
