Description
Technical field
The present invention relates to a kind of thrust device, especially have the new device of good abrasion resistance and vibration damping impact resistance.
Background technique
For power shunt type combined planetary reducer, because the characteristics of speed reducer drive mechanism, its differential stage ring gear and enclosure class sun gear link and all are buoyant member, requirement is under the situation that guarantees enough amount of floatings, differential stage ring gear and enclosure class sun gear connected body carry out axial limiting to having in relative rotation with static frame, and need to consider because connected body has the greater impact to the limit structure generation when speed reducer vibrate of big inertia.Therefore need a kind ofly can have good abrasion resistance, and spacing thrust device that can reliably working under the operating mode of vibratory impulse.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, at power shunt type combined planetary reducer differential stage ring gear and enclosure class sun gear connected body, the axial limiting thrust device must have the practical problem of good abrasion resistance and vibration damping impact resistance, and a kind of wear-resistant vibration-damping thrust device is provided.
For realizing above technical purpose, the present invention will take following technological scheme:
A kind of wear-resistant vibration-damping thrust device, comprise steel base, elastomeric plastics thrust layer and damping spring layer, elastomeric plastics thrust layer and damping spring layer are arranged at two apparent surfaces of steel base respectively, and steel base, elastomeric plastics thrust layer and damping spring layer link into an integrated entity.
Described steel base ringwise or circular or square.
Described elastomeric plastics thrust layer adopts polytetrafluoroethylmaterial material to be made, and this elastomeric plastics thrust layer directly to bind by binding agent with steel base be one.
Described elastomeric plastics thrust layer adopts the modified Teflon material to form, and this elastomeric plastics thrust layer and steel base are welded as a whole by brazing mode.
Described elastomeric plastics thrust layer is laid by the resilient pad more than three and is formed, and the damping spring layer then laying of the butterfly spring more than three forms, and they are uniformly distributed in two apparent surfaces of steel base.
On the described steel base every be provided with a resilient pad all accordingly the surface of another on steel base a slice butterfly spring is set, and resilient pad, steel base and butterfly spring link into an integrated entity by threaded fastener.
Described resilient pad circular array form distributes.
Described steel base is rounded or square, and described resilient pad and butterfly spring are all a slice, and resilient pad, steel base and butterfly spring are provided with one heart.
According to above technological scheme, can realize following beneficial effect:
Because the friction layer of wear-resistant vibration-damping thrust device of the present invention is an elastomeric plastics thrust layer, material adopts the teflon of teflon or modification, has the little (dry friction: 0.16～0.22 of friction factor; Drop lubrication: 0.013～0.040), chemical stability is good, advantages such as thermal conductivity is little, especially with friction pair to when mill, its surface layer teflon shifts to surface of friction pair, forms more stable teflon solid lubricant film, thereby under the oil-free lubrication condition, can have longer working life, and have under the condition of oil lubrication, increase exponentially its working life especially.The damping spring layer is made up of one or one group of damping spring; the damping spring of Shi Yonging has that the buffering vibration absorption ability is strong, the axial space position takies little characteristics herein; can effectively alleviate because the impact that the speed reducer vibration causes; protection elastomeric plastics thrust layer is not damaged by rigid impulse, thereby guarantees the safe and reliable work of this wear-resistant vibration-damping thrust device.
