Damage.
Preferably, described raised basal diameter m is consistent with radial width l of shim body.Raised basal diameter m
Consistent with radial width l of shim body, can more preferably make pad form spacing distance with axle platform, be easy to lubricating oil and flow into,
Increase lubricity, reduce the abrasion of axle and needle bearing.
The structure preferably, described projection and shim body are formed in one.Wherein, can be made using integrated formed structure
Obtain structure simple, reduces cost.
A kind of axle and needle bearing assembling structure, including axle, described axle includes shaft body and the shaft extension of shaft body one end, institute
The external diameter stating shaft extension is less than the external diameter of shaft body, forms the axle platform in step surface structure between described shaft extension root and shaft body,
Needle bearing is provided with described shaft extension, between the end of described needle bearing and axle platform, is provided with described pad, described pad is originally
The first end face of body and the end contact of needle bearing, the second end face of shim body is contacted with axle platform surface.Wherein, pad basis
The second end face of body is provided with some projections, can reduce the frictional force in the face of being in contact with it, thus reducing needle bearing and axle you
The abrasion in face.Spacing distance between projection can increase the gap of pad and axle you face, and these gaps are also that lubricating oil enters
Entering the passage of needle bearing and the friction surface of shaft extension, lubricity can be increased, reducing the abrasion of axle and needle bearing, thus prolonging
Long bearing service life is it is ensured that the precision of axle, performance, life-span.
Preferably, the external diameter of described pad is consistent with the external diameter of axle platform.Wherein, the external diameter one of the external diameter of pad and axle platform
Cause, so that raised complete and axle you face cooperation, so that axle platform forms more excellent spacing distance with pad, is easy to lubricating oil
Flow into and increase lubricity, reduce abrasion.
The therefore present invention has a following beneficial technique effect: structure is simple, can reduce needle bearing end face and
Axle platform weares and teares, and the second end face of shim body is provided with some projections, can reduce the frictional force in the face of being in contact with it, thus reducing rolling
Needle bearing and the abrasion in axle you face, the spacing distance between projection can increase the gap of pad and axle you face, these
Gap is also the passage that lubricating oil enters needle bearing and the friction surface of shaft extension, can increase lubricity, reduces axle and needle roller axle
The abrasion held, thus extend bearing service life it is ensured that the precision of axle, performance, life-span.
