Provided is a novel overload protection structure of a coupler. A driving friction disc is installed at one end of a driving shaft through a driving shaft key, a pressure spring is installed between a step and the driving friction disc, a driven friction disc is fixedly connected with a driven shaft through a driven shaft key, and a convex-concave matching relation is formed between concentric circular V-shaped grooves on the driving friction disc and the driven friction disc. Power of the driving shaft is transmitted through the friction force generated under the compressing conditions of the driving friction disc and the driven friction disc, and the friction force depends on pressure of the pressure spring. Therefore, the novel overload protection structure of the coupler can not only protect a prime motor from being impacted, but also protect a transmission system when overload occurs.
Description
technical field [0001] The invention relates to a structure of an overload protection coupling, in particular to a structure of a novel overload protection coupling, which belongs to the technical field of mechanical parts. Background technique [0002] Coupling is a component that connects power machinery and input shaft in mechanical transmission, and plays a role in protecting the prime mover in mechanical transmission; at present, in the coupling products, although the structure of the coupling is different , However, all couplings only have a protective effect on the impact of the prime mover, and cannot protect the overload of the transmission system. Contents of the invention [0003] The purpose of the present invention is to provide a new structure of overload protection coupling. In addition to protecting the impact of the prime mover, the structure of this overload protection coupling can also play a role in the overload of the transmission system. to the prote...
