Wearing layer, the first rolling element is provided between bearing outer ring and the bearing centre circle, and first rolling element slides positioned at first
Between groove and the second sliding groove, the 3rd sliding groove is offered on the madial wall of the bearing centre circle, is consolidated in the 3rd sliding groove
Surely there is wearing layer, the 4th sliding groove is offered on the lateral wall of the bearing inner race, is fixed with the 4th sliding groove wear-resisting
Layer, the second rolling element is provided between the bearing centre circle and bearing inner race.
Preferably, retainer is provided between first rolling element, and adjacent first rolling element is maintained by retainer
Between distance.
Preferably, second rolling element is between the 3rd sliding groove and the 4th sliding groove.
Preferably, retainer is provided between second rolling element, and adjacent second rolling element is maintained by retainer
The distance between.
Preferably, the contact surface between the wearing layer and the first rolling element and the second rolling element is designed as arc, and with
First rolling element and the second rolling element agree with.
Compared with prior art, the beneficial effects of the utility model are：This plant equipment anti-friction bearing is simple in construction：
1st, by being provided with two layers of rolling element, when carrying out the rotation of rolling element, bearing inner race drives the second rolling element
Rotate, be that the second rolling element is worn first, and during abrasion, turning for the first rolling element is driven by frictional force
It is dynamic, the normal use of device is not influenceed, and adds the pot life of device；
2nd, it is resistance to provided with matching with its radian by the contact position with circle body of the first rolling element and the second rolling element
Layer is ground, using wearing layer, weakens the frictional force suffered by rolling element so that the pot life of rolling element is protected, so as to delay
Rolling element produces the time of friction with circle body, ensure that the use of rolling element.
