Description
Technical field
The present invention relates to traction machine cushion technique field, more particularly to a kind of elevator traction mechanism damping device.
Background technology
In existing elevator, typically pass through the elevating movement of traction machine traction elevator car.In the work of elevator traction machine
During, during particularly drawing car progress fast lifting, elevator traction machine often produces vibrations, so as 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 weight capacity of Rubber shock-absorbing pad is weaker, it is impossible to the damping of the traction machine larger for weight, it is applicable
Scope is smaller；Damping spring itself can move back and forth (bounce) in damping, and damping effect is undesirable, and damping spring is easily given birth to
Rust failure, service life is shorter.Moreover, when the elevator of high-speed cruising needs to carry out brake hard, due to traction on traction machine
The self gravitation of wheel and the larger tractive force of steel wire rope, are easily caused traction machine and tumble, and influence the safety in operation of traction machine,
Need to make special beam simultaneously for the traction machine of different size, cause the unicity of beam；Meanwhile, modern electricity

The wasting of resources is caused, existing damping device is fixed position in design and installation, but installation site is needed with actual in design process
Damping position is wanted to there is certain deviation, because link position is fixed between damping device and base of traction machine, in actual installation mistake
It can not be adjusted in journey, its damping effect is by big heavy discount.Therefore, existing damping device exist weight capacity it is weaker,
The scope of application is smaller, damping effect is undesirable, service life is shorter, be applicable monistic problem.
Such as Chinese patent cN205170123U discloses a kind of damping of elevator traction machine, including some damping rubbers
Glue part, the fixed support for supporting the yielding rubber part；The yielding rubber part is arranged on the fixed support, described
The compaction direction direction to outside of yielding rubber part need to be by the structure of damping.By said structure, described in the utility model
The damping of elevator traction machine plays good damping effect, so as to protect elevator traction machine, extends making for elevator traction machine
Use the life-span.Yielding rubber part on riser and first substrate reduces elevator traction machine or so, fore-and-aft direction jointly
Vibration, yielding rubber part prevents tumbling for traction machine jointly on first substrate and second substrate.But damping in the patent
Power between mechanism is not eliminated at the top of base bottom and spandrel girder is transmitted, and a part of shaking force passes through base in use
Bottom conductive is to spandrel girder, and damping effect is not obvious；The installation site of damping is single simultaneously, it is impossible to meet different size
Under traction machine damping requirement.And for example Chinese patent CN203743298U discloses a kind of elevator traction machine damping device；Category
