Problems solved by technology

[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 not the same, but , so these couplings only protect the impact of the prime mover, and cannot protect the overload of the transmission system.

Embodiment Construction

[0009] Install the active friction disc (4) on one end of the active shaft (1) through the active shaft key (3) to ensure that the active friction disc (4) has the freedom to slide in the axial direction and has no freedom to rotate, and the pressure spring ( 2) Install between the step A and the active friction disc (4), and form a fixed connection between the passive friction disc (5) and the passive shaft (7) through the passive shaft key (6) to ensure that the active friction disc (4) and the passive friction Concentric circular V-shaped grooves on the disc (5) form a convex-concave matching relationship.

Abstract

The invention provides a coupler with an overload protection function, which is characterized in that a driving friction disk is arranged at one end of a driving shaft by a driving shaft key so as to ensure that the driving friction disk has degree of freedom (DOF) for sliding along the axial direction and non-rotational DOF; and a pressure spring is arranged between a step A and the driving friction disk, and a driven friction disk and a driven shaft form a fixed connection by a driven shaft key so as to ensure that concentric rounded V-shaped grooves on the driving friction disk and the driven friction disk form a concavo-convex cooperation relationship.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to a shaft coupling with an overload protection function, and 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 not the same, but , so these couplings only protect the impact of the prime mover, and cannot protect the overload of the transmission system. Contents of the invention [0003] The object of the present invention is to provide an overload protection coupling, which can not only protect the prime mover from impact, but also protect the transmission system from overload. [0004] The technical solution adopted by the present invention to achieve the above object is: an overload protection coupling, which i...
