Problems solved by technology

However, the column pin safety coupling still often occurs that the column pin is cut off.
After the safety pin is cut off, although the chain, shaft and other equipment are protected, it takes a long time to repair the safety pin, which reduces production efficiency

Abstract

The invention provides a frictional coupler. A driving shaft drives an outer friction disc through tooth engagement by driving a coupler seat and an associator disc, under the action of spring force, the driving shaft drives an associator inner ring seat through a friction disc, and the associator inner ring seat drives a driven shaft to rotate. When the load torque is larger than the set torque (friction moment which can be transmitted by the friction disc group) of the coupler, slippery occurs on the indirect contact surface of the friction discs; when the load torque is smaller than or equal to the set value of the coupler, the coupler transmits normally. The value of transmitted torque can be adjusted. An adjusting nut is adjusted, the value of the spring force is controlled by means of compressing and releasing a spring, and then the friction force of the friction disc group is controllable; and the value of the friction force determines the value of transmitted torque, so that the control over the value of the transmitted torque is achieved.

Description

technical field [0001] The invention relates to a friction coupling. Background technique [0002] Coupling is a component used in mechanical transmission to connect two shafts in different mechanisms to make them rotate at the same time and transmit torque. There are many types of couplings, which can be generally divided into two categories: rigid couplings and flexible couplings. Rigid couplings have no ability to compensate for relative displacement, and the two shafts to be connected require strict alignment. The structure is generally simple, easy to manufacture, and can transmit large torques. Commonly used rigid couplings mainly include flange couplings, sleeve couplings, and clamp couplings. Flexible couplings are further divided into flexible couplings with elastic elements and flexible couplings without elastic elements. The characteristic of the flexible coupling is that it has the ability to compensate the axial, radial and angular relative offsets of the two...
