A kind of bearing structure, comprise outer ring, inner ring, rolling element, retainer; Rolling element is between the raceway of inner ring and outer ring; Also comprise two ring-type oil sealings, laterally be located between described outer ring, inner ring, and these two ring-type oil sealings lay respectively at described a plurality of rolling elements both sides; It is characterized in that: described retainer adopts the italic formula, and the bottom, pocket hole of retainer is with tang; Evenly be provided with one deck outer ring self-lubricating sliding layer on the inner hole surface of described outer ring, evenly be provided with one deck inner ring self-lubricating sliding layer on the outer side surface of described inner ring; Also be provided with the conductive member of the described inner ring of conducting and described outer ring between described inner ring and outer ring, described conductive member comprises outer section with the inwall of being close to described outer ring with contacted the first inner segment of described inner ring.
Wherein, described conductive member is integrally formed by elastic conducting material.
Wherein, described inner ring self-lubricating sliding layer, outer ring self-lubricating sliding layer are bonded on inner ring and outer ring by pyrolytic coating respectively.
Compared with prior art, the advantage of bearing structure described in the utility model:
1, the utility model is simple in structure, application is convenient, take polyimide as main self-lubricating sliding layer friction factor is low, hardness is high, lubricating ability is far away higher than traditional steel axle, its material itself has the characteristic of Wear-resistant, high-temperature resistant, by increasing this self-lubricating sliding layer, can effectively improve due to high temperature and bearing failure that at a high speed wearing and tearing cause, the working life of greatly having improved bearing.
2, the shoulder block of the both sides of Internal and external cycle of the present utility model just differs, and is the low of the shoulder block of a side wherein processing for the more steel ball of packing into, and bearing load carrying capacity is strengthened.
3, owing between the inner ring of bearing and outer ring, being provided with conductive member, make the inner ring of bearing and outer ring realize conducting.When bearing rotates along with axle, the static that inner ring generates flows to outer ring along conductive member, then the parts such as bearing support conduct current is connected with outer ring by outer ring, casing, realizes current earthing.Thereby the static generated during by bearing rotary is derived.Effectively avoid static to accumulate in bearing, avoid generating static spark, effectively reduce the possibility of breaking out of fire, improve the safety and reliability of bearing structure.
