Description
Technical field
The present invention relates to traction machine cushion technique field more particularly to a kind of elevator traction mechanism damping devices.
Background technique
In existing elevator, the general elevating movement for passing through traction machine traction elevator carriage.In the work of elevator traction machine
In the process, during especially traction carriage carries out fast lifting, elevator traction machine often generates vibration, to influence electricity
Terraced traveling comfort.In order to solve this problem, Rubber shock-absorbing pad or damping typically now are installed in elevator traction motor spindle
Spring carries out damping；But the load-bearing capacity of Rubber shock-absorbing pad is weaker, is not used to the damping of the biggish traction machine of weight, is applicable in
Range is smaller；Damping spring itself can move back and forth (bounce) in damping, and damping effect is undesirable, and damping spring is easy life
Rust failure, service life are shorter.Moreover, when the elevator of high-speed cruising needs to carry out emergency braking, due to traction on traction machine
The self gravity of wheel and the biggish tractive force of wirerope, are easy to cause traction machine to tumble, influence the safety in operation of traction machine,
It needs to make dedicated resilient cushion simultaneously for the traction machine of different size, causes the unicity of resilient cushion；Meanwhile modern electricity
Its damping of the bigger traction machine of size requires higher in ladder, and existing damping device is all only applicable to the traction machine of single specification,
