1results about How to "Compensation displacement" patented technology

This utility model discloses a flexible coupling for a small plunger pump motor shaft, belonging to the field of coupling technology. It includes a pair of connecting bushings for connecting the motor output shaft and the plunger pump input shaft. Both bushings are hollow, and a connecting disc is fitted at each end close to the other. An elastic connector is provided between the two connecting discs, suspended between them. Six sets of wear-resistant pads are circumferentially distributed at equal intervals on both sides of the elastic connector, and these six sets of wear-resistant pads are in contact with the two connecting discs. The elastic connector is made of rubber and is hexagonal. This technical solution effectively solves the problems of rigid couplings being unable to compensate for displacement and having high vibration and noise, as well as the problems of existing flexible couplings having complex structures, limited buffering effects, and rapid wear of the elastic body, through the structure of the hexagonal elastic connector made of rubber, wear-resistant pads, connecting bushings, and connecting discs. It is also easy to maintain and extends service life.
