Description
Technical field
The present invention relates to plane bearing technical field more particularly to a kind of dissection type plane bearing and its assembly methods.
Background technique
Common plane bearing (thrust bearing) be by the plane retainer component with needle roller or cylindrical roller or steel ball and
The element of faced washer composition, plain thrust bearing are primarily subjected to axial load in assembly, are suitable for bearing one side axial
On the lower parts of load, revolving speed, it is widely used.But common plane bearing will appear following point in use: first,
Need on the mid diameter axis smaller than both ends diameter use plane bearing when, common plane bearing due to be full circle just
It is not available；Second, since blowout patche, seat ring and retainer are separation, and plane bearing has a disadvantage, and axial load is big,
It cannot bear radial power；Third, blowout patche, seat ring and the retainer of plane bearing are separation, and grains of sand dust etc. just compares appearance
Easily enter Bearing inner.
