Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 195 words
A self-aligning bushing setup comprising a shaft, an inner race having a position surrounding one end of the shaft, the inner race having a spherical type outer surface and having an inner and an outer end relative to the shaft as a whole longitudinally speaking, an outer race having a spherical type inner surface mating with the spherical type outer surface of the inner race to enable relative movement as between inner and outer race, an end plate across the outer end of the inner race and having an inner end surface mating with an outer end surface of that inner race, said respective mating end surfaces preventing relative rotation between the end plate and the inner race by at least part of the mating surfaces of the end plate and the inner race having an oblique angle with respect to the axis of the shaft and being assymetrical composed to any figure of rotation developed symmetrically about the axis of rotation of the shaft, means for positively affixing the end plate to the shaft, and means to prevent the inner race from moving axially out of the effective mating position with the end plate.
Claim 2
Dependent Claim 195 words
A self-aligning bushing setup comprising a shaft, an inner race having a position surrounding one end of the shaft, the inner race having a spherical type outer surface and having an inner and an outer end relative to the shaft as a whole longitudinally speaking, an outer race having a spherical type inner surface mating with the spherical type outer surface of the inner race to enable relative movement as between inner and outer race, an end plate across the outer end of the inner race and having an inner end surface mating with an outer end surface of that inner race, said respective mating end surfaces preventing relative rotation between the end plate and the inner race by at least part of the mating surfaces of the end plate and the inner race having an oblique angle with respect to the axis of the shaft and being assymetrical composed to any figure of rotation developed symmetrically about the axis of rotation of the shaft, means for positively affixing the end plate to the shaft, and means to prevent the inner race from moving axially out of the effective mating position with the end plate.
Claim 3
Dependent Claim 42 words
A self-aligning bushing according to claim 1, in which the means to prevent the inner race from moving axially out of mating position with the end plate is a shoulder on the shaft cooperating with the inner end of the inner race.
Claim 4
Dependent Claim 19 words
A self-aligning bushing according to claim 1, in which the end plate is affixed to the shaft by bolts.
Claim 5
Dependent Claim 27 words
A self-aligning bushing according to claim 1, in which the mating surface of the end plate and the end of the inner race lie in a plane.
Claim 6
Dependent Claim 36 words
A self-aligning bushing according to claim 1, in which two mating surfaces of the end plate and the end of the inner race lie in a curve which is concave with respect to the end plate.
Claim 7
Dependent Claim 37 words
A self-aligning bushing according to claim 1, in which two mating surfaces between the end plate and the one end of the inner race lie in a curve which is convex with respect to the end plate.
Claim 8
Dependent Claim 44 words
A self-aligning bushing according to claim 1, in which the mating surfaces of the end plate and the one end of the inner race are tapered from the outside toward the interior in a manner which is concave with respect to the end plate.
Claim 9
Dependent Claim 44 words
A self-aligning bushing according to claim 1, in which the mating surfaces of the end plate and the one end of the inner race are tapered from the outside toward the interior in a manner which is convex with respect to the end plate.
