Transmission shaft connecting flange shock-absorbing protection device

Abstract

The invention provides a transmission shaft connecting flange shock-absorbing protection device. The transmission shaft connecting flange shock-absorbing protection device includes a shock-absorbing disc, connecting discs, and shock-absorbing connectors; a through hole is arranged on the shock-absorbing disc, and a shock-absorbing spring is installed in the through hole; two connecting discs are arranged, and the two connecting discs are arranged oppositely above and below the shock-absorbing disc, which are a first connecting disc and a second connecting disc; a ball head hole is arranged oneach connecting disc; the two connecting discs are used for connecting a transmission shaft and a reducer; two shock-absorbing connectors are arranged, which are arranged oppositely along the two sides of the shock-absorbing disc; each shock-absorbing connector is arranged between the shock-absorbing disc and the connecting disc; one end of the shock-absorbing connector is installed in the ball head hole of the connecting disc, and the other end is installed in the through hole of the shock-absorbing disc, so as to be used for shock absorption by cooperating with a shock-absorbing spring; andthe shock-absorbing connectors are also connected to the shock-absorbing disc for transmitting torque. The transmission shaft connecting flange shock-absorbing protection device has a good shock-absorbing effect, can improve the operation stability and service life, has a simple structure, is convenient to install, and is convenient for industrialization promotion and use.

Description

technical field [0001] The invention belongs to the technical field of shock absorption of transmission equipment in the field of metallurgical equipment, and in particular relates to a shock absorption protection device for connecting flanges of transmission shafts. Background technique [0002] In metallurgical equipment, some large-tonnage or high-torque equipment uses a universal joint shaft for transmission. Usually, the transmission shaft is connected to the reducer, and the engine transmits torque to the reducer through the drive shaft. On the other hand, there is a deviation between the axis center of the transmission shaft and the transmission shaft, which causes equipment vibration, which is difficult to eradicate. In addition, equipment vibration and other reasons will have impact on the transmission shaft. The parts of the cross package, the reducer or the motor are damaged, which will affect the stability and service life of the equipment. [0003] Most of the ...

[0003] Most of the damping structures in the prior art use rubber gaskets installed between the connecting flanges. The damping effect of this damping structure is limited and cannot achieve a good damping effect. Therefore, it is necessary to design a damping The device eliminates the impact of the transmission shaft vibration on the equipment
