Abstract

The invention provides an elastic shaft coupler. A plurality of first positioning holes (5) are formed in one end face of a driving shaft disc (3); top pressing parts (6), first springs (7) and balls (8) are arranged in the first positioning holes (5); the pore diameter of an end face, located on the driving shaft disc (3), of each first positioning hole (5) is smaller than the diameter of each ball (8); each top pressing part (6) is used for tightly pressing each first spring (7) on the corresponding ball (8); one part of each ball (8) stretches out of the end face of the driving shaft disc (3) and is embedded into a corresponding second positioning hole (9) to fit the end face of the driving shaft disc (3) and the end face of a driven shaft disc (4); one end of each second spring (12) is pressed into a spring positioning hole (12) in a one to one correspondence and the end faces of the other ends of the second springs (12) are fitted with the end face of the inner side of a sleeve body (10). According to the elastic shaft coupler provided by the invention, torque transmission is carried out through the ball so that overload protection of a torque can be realized; the shaft coupler is internally provided with an elastic sheet and the springs so that stable transmission of the torque can be effectively guaranteed.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an elastic shaft coupling. Background technique [0002] A coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms so that they rotate together to transmit torque. In some high-speed and heavy-duty power transmissions, the coupling can also play the role of buffering, shock absorption and improving the dynamic characteristics of the shafting. In a sense, the coupling is an irreplaceable mechanical part in the machinery industry. [0003] Couplings are generally divided into rigid couplings and elastic couplings. The rigid coupling has the advantages of simple structure and easy manufacture, but its use conditions are harsh, and it must be used under the condition that the two axes are strictly aligned and no relative displacement occurs. In the case of misalignment of the two shafts, the rigid coupling will generate large vibrations,...
