Problems solved by technology

[0002] In the prior art, the intermediate coupling of the coupling is generally mainly composed of a cylinder and flanges arranged at both ends of the cylinder, and is made of metal materials, and its structure is generally an integral structure; because the coupling The coupling and its coupling cannot play a good role in damping and absorbing shock vibration when rotating at high speed, thus affecting the transmission effect. Axial, radial and angular displacement can not play any compensation role

Abstract

The invention provides a flexible coupling, comprising a cylinder body and flanges which are arranged at two ends of the cylinder body. The invention is characterized in that the cylinder body is an FRP cylinder body; the flanges are fixedly connected with or integrated into a whole with a taper sleeve or a cylinder sleeve; the two ends of the FRP cylinder body are sheathed with, fixedly bonded to or fixedly connected with the taper sleeve or the cylinder sleeve respectively. The invention is especially suitable for the connection of a speed increasing box in wind power generation equipment and a wind power generation set, plays a good damping and impact and vibration absorption role, has the capability of providing the displacement compensation, effectively improves the motion quality and stability of transmission machines, reduces the noise and improves the safety performance of the equipment.

Description

technical field [0001] The invention relates to a component of a coupling that transmits rotational motion—an intermediate coupling of a high-speed flexible coupling, in particular to a flexible coupling. It is suitable for the connection device between the gearbox and the wind power generating set (especially the wind power generating equipment above 1.5 MW) in the wind power generation equipment, and can also be used as the power transmission device of other equipment. technical background [0002] In the prior art, the intermediate coupling of the coupling is generally mainly composed of a cylinder and flanges arranged at both ends of the cylinder, and is made of metal materials, and its structure is generally an integral structure; because the coupling The coupling and its coupling cannot play a good role in damping and absorbing shock vibration when rotating at high speed, thus affecting the transmission effect. Axial, radial and angular displacements cannot play any c...
