Description
Technical field
The utility model relates to a kind of wheel hub, relates in particular to a kind of wheel hub that facilitates oiling.
Background technology
There is the situation of oiling inconvenience in wheel hub of the prior art, easily produces the phenomenon of leakage of oil, and the installation that affects hub bearing is stable, can not meet people's requirement.
Utility model content
The purpose of this utility model is to provide a kind of wheel hub that facilitates oiling, prevents that wheel hub from producing the phenomenon of leakage of oil, increases the stability of hub bearing, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of wheel hub that facilitates oiling, this wheel hub comprises an outer ring and an inner ring, between described outer ring and inner ring, be provided with roller and seal ring assembly, on described roller, be provided with retainer, it is characterized in that, in the outer rim of described wheel hub, be provided with an oil nozzle, steel ball and spring are installed in described oil nozzle, described steel ball is arranged on the oil port of oil nozzle, and one end of steel ball contacts with described spring, and the oil port of oil nozzle is provided with retention tab.
Further, the cross section of described oil nozzle is hexagon.
Useful technique effect of the present utility model is:
Prevent that wheel hub from producing the phenomenon of leakage of oil, on zerk, also have leak free design, by the combination of steel ball and spring, oil nozzle is blocked, can only back down from outside, and the position of oil nozzle design and angle be all specific, do not affect stable that hub bearing installs, increase the stability of hub bearing.
