Elastic coupler

Abstract

The invention provides an elastic coupler which comprises an output end half coupler, an elastic gasket, a nylon pin, a metal pin sleeve, an internal hexagonal screw plug, an input end half coupler, a right part, a left part and a screw plug. The elastic coupler is characterized in that pin holes are arranged in corresponding contact faces of the output end half coupler and the input end half coupler; the left part is arranged at the lower portion of the output end half coupler, and the right part is arranged at the lower portion of the input end half coupler; the nylon pin is arranged inside the pin holes, and the metal pin sleeve is arranged outside the nylon pin. The elastic coupler is simple in structure and easy to assemble and disassemble; due to the fact that the metal pin sleeve is additionally arranged outside the nylon pin, shearing force is converted into pressure stress, the torque transmitted by the elastic coupler is increased, and the service life of the nylon pin is prolonged; axial movement of the nylon pin and the metal pin sleeve inside the pin holes is limited through the inner hexagonal screw plug, and vibration and noise are lowered; the left part is arranged at the lower portion of the output end half coupler, and the right part is arranged at the lower portion of the input end half coupler, so that both the left part and the right part achieve the damping, sound insulation and dustproof effects.

Description

technical field [0001] The invention relates to a shaft coupling, in particular to an elastic coupling. Background technique [0002] Nylon pin elastic couplings are widely used as traditional torque transmission equipment. The traditional nylon pin elastic couplings are composed of output half couplings, nylon pins, retaining rings and input half couplings. The nylon pins connect the two The half-couplings are connected together. Since the nylon pin is directly placed in the two rigid half-coupling pin holes, the nylon pin bears a large torque during operation, which is easy to wear and break, and the coupling is directly connected to the shaft end. The link, the machine loss is relatively large. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an elastic coupling that can effectively solve the problems in the background technology. [0004] In order to solve the problems of th...
