ABSTRACT:
A shock-absorbing sprocket or gear assembly or like torsionally elastic device is described having resilient cushioning means interposed between mating lugs of the hub and rim to smooth and dampen torsional shocks and vibrations produced by a power drive train. An improved radial bearing surface is provided which maintains symmetry of the bearing load with respect to the drive, and which ensures concentricity between the hub and rim and keeps the rim from wobbling axially or orbiting radially with respect to the hub during operation. The cushioning means are configured relative to the hub and rim to accommodate angular displacements of at least 9.degree.. A power transmission drive system employing the shock-absorbing sprocket of the invention is also described.
