An Axial Diaphragm Coupling

Abstract

The invention discloses an axial membrane coupling. Due to the existence of universal couplings in the existing structure, in order to ensure the synchronization of the main and driven shafts, the practical application of universal couplings generally adopts a duplex form, and the bearing is a wearing part of the universal coupling, etc. Problem: Because the diaphragm coupling of the existing structure cannot adapt to large angular displacement and other problems, it directly affects the performance and service life of the coupling. In order to solve these problems, a new type of diaphragm coupling in which the diaphragm group is arranged along the axial direction of the coupling is designed. The axial diaphragm coupling of this structure has the unique working performance of diaphragm coupling and universal coupling, which can not only compensate for large angular displacement, but also ensure the synchronization of the main and driven shafts. Improve the bearing capacity and service life of the coupling.

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. The universal coupl...

Problems solved by technology

However, in order to ensure the synchronization of the main and driven shafts, the universal joints are in the form of duplexes in practical applications, and the bearings are the vulnerable parts of the universal joints.

Due to the unreasonable structure of the existing diaphragm coupling, the angular displacement that can be compensated sometimes cannot meet the needs; although the universal coupling has strong angular displacement compensation ability, there is synchronization between the main and driven shafts and bearings are vulnerable, so in order to solve the problems of diaphragm couplings and universal couplings, it is necessary to invent a diaphragm coupling with a more reasonable structure
