When needing to add lubricant oil, oil filler pipe is inserted in oil hole and carries out oiling, oil duct is provided with owing to running through between oil hole and ring raceway, and oil duct and ball against, therefore lubricant oil can flow in ball along oil duct, rotation along ball makes lubricant oil cover ball on the surface, avoid waste, and bearing inner ring two ends end face is provided with some oil holes, and all run through between each oil hole and ring raceway and be provided with oil duct, be connected by looping pit between some oil holes, as long as therefore add lubricant oil in an oil hole, namely flow in each oil duct by looping pit, thus oiling better effects if, being provided with oil hole because bearing inner ring two ends end face runs through in addition, when dismantling bearing, one end being inserted in oil hole with the pull bar of block, by pulling pull bar can lower bearing for convenience detach, avoiding the extra dismounting strong point of finding to damage bearing.
In above-mentioned a kind of agricultural machinery bearing, described axis hole is square, and described axis hole can insert square shaft.
Therefore connect more firm after inserting square shaft, prevent axle and axis hole from skidding.
In above-mentioned a kind of agricultural machinery bearing, described axis hole four sidewalls are equipped with curve bath, and described four curve baths can insert circular shaft.
Therefore circular shaft that can also be compatible traditional.
In above-mentioned a kind of agricultural machinery bearing, described each oil hole two ends are equipped with groove on the end face of bearing inner ring two ends, and dismountable dust plug being embedded with shutoff oil hole in each groove.
When not injecting lubricant oil, inserting dust plug and playing dust-proof effect.
In above-mentioned a kind of agricultural machinery bearing, described oil hole is with internal thread.
Internal thread is set and is connected tightr with externally threaded pull bar.
In above-mentioned a kind of agricultural machinery bearing, described ring raceway both sides are provided with annular dust cover.
Compared with prior art, the utility model tool has the following advantages:
When needing to add lubricant oil, oil filler pipe is inserted in oil hole and carries out oiling, oil duct is provided with owing to running through between oil hole and ring raceway, and oil duct and ball against, therefore lubricant oil can flow in ball along oil duct, rotation along ball makes lubricant oil cover ball on the surface, avoid waste, and bearing inner ring two ends end face is provided with some oil holes, and all run through between each oil hole and ring raceway and be provided with oil duct, be connected by looping pit between some oil holes, as long as therefore add lubricant oil in an oil hole, namely flow in each oil duct by looping pit, thus oiling better effects if, being provided with oil hole because bearing inner ring two ends end face runs through in addition, when dismantling bearing, one end being inserted in oil hole with the pull bar of block, by pulling pull bar can lower bearing for convenience detach, avoiding the extra dismounting strong point of finding to damage bearing.
