Problems solved by technology

However, the coupling of this structure still has problems such as the impact between the limit block and the half coupling, and the existence of no resistance when the coupling moves axially. Therefore, it is necessary to invent a diaphragm with a more reasonable structure. Coupling

Abstract

The invention discloses an axial elastic-limited diaphragm coupling. As a traditional diaphragm coupling structure cannot limit the axial displacement, the axial displacement of a half coupling of the coupling is excessive to directly influence the service performance and the service life of the coupling; and as the traditional diaphragm coupling structure cannot apply resistance to axial displacement to cause collision between the half coupling and a diaphragm set, sparks can be generated in collision between metal parts. In order to solve the problems, an elastic limiting piece is added between the half coupling and the diaphragm set for limiting displacement of the half coupling, so that the displacement buffering purpose is achieved, and the service life of the diaphragm coupling is largely prolonged.

Description

technical field [0001] The invention relates to a coupling of a mechanical transmission device, which is a coupling device for movement and power transmission between a prime mover (such as an electric motor, an internal combustion engine, etc.) and a working machine (such as a pump, a reducer, etc.), and belongs to the technical field of mechanical transmission . Background technique [0002] Couplings are widely used in rotating machinery, including rigid couplings and elastic couplings. Diaphragm coupling is a new type of coupling, which has the advantages of transmitting large torque, allowing large displacement error, allowing high-speed rotation, mitigating impact vibration, generally does not need lubrication, and is easy to install and maintain. It is widely used in National defense, shipbuilding, aviation, petrochemical, vehicles, machinery and other industries can replace gear couplings, elastic sleeve pin couplings and other coupling devices. However, due to the...
