Problems solved by technology

However, due to the unreasonable structure of the existing diaphragm coupling, the angular displacement, axial displacement, and radial displacement that can be compensated sometimes cannot meet the needs of users; or when the coupling is in a large angular Under the repeated action of displacement, axial displacement and radial displacement, the diaphragm is prone to fatigue damage
The diaphragm couplings of the existing structure either cannot adapt to large angular displacement, axial displacement, and radial displacement, which limits the application range of the coupling, or cannot effectively reduce the additional displacem

Abstract

The invention discloses a diaphragm coupling of a triple diaphragm group. As the diaphragm coupling of the existing structure cannot adapt to relatively large angular displacement, axial displacementand radial displacement, the application range of the coupling is limited, or as the diaphragm coupling of the existing structure cannot effectively reduce the load which is caused by the additional displacement and is added to a diagram, the operational performance and service life of the coupling are directly affected. In order to solve the problems, the triple diaphragm group structure is invented; a middle diaphragm group is fixedly connected to a self-aligning bearing, so that the self-aligning performance of the self-aligning ball bearing can be utilized to reduce the additional load acting on the diaphragm due to the additional displacement, and thus, the purposes of compensating the relatively large angular displacement, axial displacement and radial displacement and greatly prolonging the service life of the diaphragm coupling are achieved.

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...
