Problems solved by technology

Due to the unreasonable structure of the existing elastic coupling, the angular displacement, axial displacement, and radial displacement that can be compensated sometimes cannot meet the needs; or when the coupling has a large angular displacement or axial displacement Under the repeated action of displacement and radial displacement, the components that make up the coupling are prone to fatigue damage, which directly affects the performance and service life of the coupling
The axial bellows coupling is a kind of elastic coupling. Although it has good displacement compensation ability, it is mainly used in small-power precision machinery and control mechanisms that require compact structure and high transmission accuracy. It is not suitable for large For power transmission occasions, it is necessary to invent an elastic coupling with a more reasonable structure

Abstract

The invention discloses an axial rod piece elastic coupling. As the existing elastic coupling is not reasonable in structure and the compensated angular displacement, axial displacement and radial displacement cannot meet the demand sometimes; or under the repeated action of the larger angular displacement or axial displacement and radial displacement, the components of the coupling is likely to have fatigue failure to directly affect the service performance and the service life of the coupling; or the existing elastic coupling is not suitable for the high-power transmission occasion. To solvethe problems, the invention discloses the axial rod piece elastic coupling. As the self omega shaped structure, the U shaped structure, the arch shaped structure and the spiral structure of the axialrod piece, the axial rod piece elastic coupling has excellent rigidity, transmission movement and power, and also has excellent elasticity to realize compensation of the axial displacement, the radial displacement and the angular displacement to improve the service performance and the service life of the coupling.

Description

technical field [0001] The invention relates to a shaft 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 and an internal combustion engine and a working machine such as a pump and a reducer, 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. Due to the unreasonable structure of the existing elastic coupling, the angular displacement, axial displacement, and radial displacement that can be compensated sometimes cannot meet the needs; or when the coupling has a large angular displacement or axial displacement Under the repeated action of displacement and radial displacement, the components that make up the coupling are prone to fatigue damage, which directly affects the performance and service life of the coupling. The axial bellows...
