Quick-mounting universal coupler

Abstract

A quick-mounting universal coupler comprises a driving shaft connector and a driven shaft connector. The driving shaft connector is connected with a driving device main shaft through a key, the driven shaft connector is connected with a driven device main shaft through a key, and a coupler middle shaft is arranged between the driving shaft connector and the driven shaft connector. Horizontally arranged round bosses are arranged on the two sides of one end of the driving shaft connector, and vertically arranged round bosses are arranged on the two sides of one end of the driven shaft connector. Four round grooves arranged in a cross shape are formed in the coupler middle shaft, two of the four round grooves are horizontally arranged, openings of two of the four round grooves are formed in one side of the driving shaft connector, the other two of the four round grooves are vertically arranged, and openings of the other two of the four round grooves are located in one side of the driven shaft connector. Semicircular grooves for storing lubricating grease are formed in the bottoms of the round grooves, four semicircular elastic pads are arranged in the round grooves arranged in the cross shape, and the four semicircular elastic pads are connected with the round bosses on the two sides respectively. By means of the round concave-convex structural design, the coupler has certain angular deviation and radial deviation adjusting capacity at the same time and has the advantages of being simple in structure and convenient to mount and maintain, radial deviation and angular deviation can be eliminated at the same time, and the application range is wide.

Description

technical field [0001] The invention relates to a quick-install universal joint. Background technique [0002] In the machinery industry, couplings, as common components, are widely used in various mechanical transmissions to transmit motion and power. Due to the influence of manufacturing and installation deviations, deformation after loading, and temperature changes, the two shafts connected by the coupling inevitably have a certain position deviation. The existing universal joints are large in size and complex in structure, and their application occasions are greatly limited. However, most of the traditional couplings with small size and simple structure can only solve a single position deviation problem. Contents of the invention [0003] The purpose of the present invention is to provide a quick-install universal coupling. Through the design of the circular concave-convex structure, the coupling has certain angular deviation and radial deviation adjustment capabiliti...
