Abstract
The elastic parts of a resilient shaft coupling are bridged by regularly arranged shock absorbers forming a regular polygon.
Claims5
In a highly elastic coupling having a first, inner annular coupling portion and a second, outer annular coupling portion connected to the first portion via radially extending elastic means for rotation about a common axis, the improvement comprising:
- a plurality of radially extending arms connected to said first coupling portion;
- a plurality of holders connected to said second coupling portion, extending axially therefrom and being symmetrically interspaced between said arms;
- a plurality of shock absorbers regularly arranged about said axis and connected respectively to said arms and said holders so that each holder and each arm is connected to two of said shock absorbers, so that the shock absorbers act parallelly to the elastic means to obtain attenuation of rotational oscillations of the parts relative to each other.
