Embodiment Construction

[0023] Such as Figure 1 to Figure 6 As shown, an air buffer device for oil pressure dismounting of the conical surface interference coupling, including a cylinder 1, a piston 3 arranged in the cylinder 1 and a spring 6 capable of restoring the piston 3, the spring 6 is at the same time There is a certain buffering effect during the disengagement process of the contained part. The piston 3 slides in the cylinder body 1 to form an air chamber 13 with the cylinder body 1. The spring 6 is arranged between the bottom of the cylinder body 1 and the piston 3. A throttling valve 8 is arranged on the side wall of the cylinder body outside the lower side of the stroke range of the piston 3, which acts as a buffer by throttling the air.

[0024] The side wall of the cylinder block 1 within the stroke range of the piston 3 is provided with an exhaust port 7, and the position of the exhaust port 7 determines the distance that the contained part and the containing part are quickly disengag...

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...
