An Air Buffer Device Used for Oil Pressure Dismounting of Conical Surface Interference Coupling

Abstract

The invention discloses an air buffer device for oil pressure removal of conical surface interference coupling, which belongs to the field of buffer devices. The air buffer device for oil pressure removal of conical surface interference connection includes a cylinder body and a There is a piston in the cylinder that can slide in the cylinder and a spring that can reset the piston. The piston and the cylinder form an air chamber. The spring is arranged between the bottom of the cylinder and the piston. An exhaust port is provided on the side wall of the cylinder body, and a throttle valve is provided at the lower part of the side wall of the cylinder body outside the stroke range of the piston. The invention has the advantages of simple structure, good cushioning effect, low vibration, low noise, convenient manufacture, friendly environment, and prolongs the service life of the disassembly tooling at the same time.

Description

technical field [0001] The invention relates to a buffer device, in particular to an air buffer device used for hydraulically dismantling the interference connection of a conical surface. Background technique [0002] With the implementation of the national clean energy policy, the wind power industry has been vigorously developed, and wind power speed increasers have entered mass production. The planetary carrier of the wind power speed reducer and the main shaft have a conical surface interference connection method. When processing the planetary carrier of this connection method, a "false shaft" with the same size as the actual main shaft is required to be assembled with the planetary carrier according to the actual interference. , and then process the planet carrier to ensure the tolerance after actual assembly. In this process, it is necessary to frequently disassemble the dummy shaft with oil pressure. The disengaged dummy shaft has a lot of kinetic energy, and when it...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the above-mentioned problems in the process of oil pressure dismantling of the conical surface interference connection, when the disengaged dummy shaft collides with the dismantling tool, there will be a lot of vibration and noise, and the impacted tool or the ground will be seriously damaged, and the research and design An Air Buffer Device Used for Oil Pressure Dismounting of Conical Surface Interference Coupling
