Compared with prior art, beneficial effects of the present invention are at least one of following：
The present invention is equipped with damping, can be in pulley driving equipment moving process, and effectively slow pulley rushes equipment transmission
Hit power.
The present invention by screw rod and nut progress it is spacing, the support force of upper backup pad can be made more stable, lower supporting plate by
Displacement can control after impact displacement, while cost is also very cheap.
The present invention is by setting spring to increase the buffering effect of elastic plate.
The present invention by the way that spring is connected with upper backup pad, lower supporting plate, can lower supporting plate after withstanding shocks soon
Position is replied immediately, and discharges the pressure in elastic plate.
The present invention makes stent and damping have preferable stability, stability by setting ribbed stiffener.
The present invention can reduce impact force caused by pulley vibrations by setting elastic layer in pulley surface.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Refering to what is shown in Fig. 1, one embodiment of the present of invention is：A kind of vibration-damping pulley, including stent 1, above-mentioned 1 lower end of stent
Equipped with pulley 2, damping 3 is installed in above-mentioned 1 upper end of stent, and above-mentioned damping 3 includes upper backup pad 4, lower supporting plate 5, bullet
Property plate 6, the lower end of above-mentioned lower supporting plate 5 is connected with stent 1, and elastic plate 6, above-mentioned elastic plate 6 are installed in above-mentioned 5 upper end of lower supporting plate
Upper end sets upper backup pad 4, is connected between above-mentioned upper backup pad 4 and lower supporting plate 5 by caging bolt 7, pulley is 2 in movement
During, it is given a shock, drives stent 1 to shake, its shaking force passes to damping 3 by stent 1, its lower supporting plate 5 is born
Stamping press caused by vibrations, and power is transferred to elastic plate 6, the support force to elastic plate 6 is to provide by support plate 4, it is propped up
Support force is more than impact force, and then elastic plate 6 is compressed deformation, discharges stamping press by both sides, into without making impact force action
In upper backup pad 4, equipment is avoided to be impacted, after impact is discharged, elastic plate 6 is gradually resetted further according to self-characteristic.
