Description
Technical field
The present invention relates to mechanical equipment technical field, more particularly to a kind of bushing centring means.
Background technology
Bushing has been the ring set of pad effect.In moving component, the abrasion of part is caused because of long-term friction, when
Axle and the gap wear in hole to a certain extent when have to renewal part, therefore from hardness is relatively low, wearability is preferable
Material is axle sleeve or bushing, can so reduce the abrasion of axle and seat, when axle sleeve or liner wear are changed to a certain extent,
The cost because changing axle or seat can be so saved, in general, bushing is used with seat and is interference fitted, and is matched somebody with somebody with axle using gap
Close because no matter how or can not avoid abrasion, the life-span can only be extended, and axial workpiece be comparatively easier add
Work.Axle sleeve is relatively low in some rotating speeds, the place that radial load is higher and clearance requirement is higher（Such as camshaft）Rolled for substituting
Bearing（Axle sleeve also a kind of sliding bearing at last in fact）, material requirements hardness is low and wear-resisting, the ground scraping of inner hole of shaft sleeve, can reach
To higher fit precision, there must be the oil groove of lubricating oil on inwall, the lubrication of axle sleeve is extremely important, if dry grinding, axle and axle
Set will soon be scrapped.Sleeve is widely used in each field, and bushing is exactly to need to realize to determine first during Automatic manual transmission
The heart, it is easy to and axle and seat assembling.Centring means（Center Master）It is mounted on pressing machine, can be in Automated assembly
In production line, the position alignment device of errors of centration is compensated, common centring means structure is complex, and cost is higher, and
Bushing is easily scratched in centering process, reliability is poor.
