Face is parallel, and thickness is slightly less than the external diameter of ball；The upper and lower surface of cambered surface sliding block is arc surface, and radian is identical with raceway.
In the compound thrust bearing of skid as described above, inclined plane slide block, plane sliding block, each surface progress of cambered surface sliding block are resistance to
Mill processing is designed to Non-smooth surface bionic surface structure, and each shoe surface can open up oil groove.
The compound thrust bearing of skid as described above can be used alone, or multiple row is applied in combination, or by multiple row rolling element group
Close and use.
Beneficial effects of the present invention：(1) the advantages of sliding compound thrust bearing has merged rolling bearing and sliding bearing, and nothing
Retainer, the high rotating speed of rolling bearing was both maintained, and also maintained the high bearing capacity of sliding bearing；(2) it is multiple under local function
Sympodium holds middle roller or ball and elastic deformation occurs at first, when deforming more than a certain amount of, sliding block and upper and lower raceway contact, rises and holds
Load acts on, and sliding block moves together with rolling element is in raceway；(3) impact under operating mode, sliding block can ensure that rolling element does not rupture
Deng failure；(4) shoe surface can open up oil groove, ensure sufficient lubrication, and each surface of sliding block carries out Wear-resistant Treatment or carried out bionical
Non-smooth surface designs, so as to improve its wearability, drag reduction.
