Description
Technical field
The utility model belongs to farm machinery parts technical field, relates to a kind of agricultural machinery roller bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.
Traditional bearing lubricating oil filling is all by the fuel filler neck on bearing support toward lubricating oil filling in bearing, to be filled into inside the ball between bearing inner ring with outer race more difficult during oiling, lubricant oil can flow to everywhere and can not arrive ball place, so not only cause waste, also easily cause bearing damage because lubricant oil is not enough.And at present the method for dismounting of bearing mainly contains hammering method, pushing method and heat and tears method open, owing to lacking the strong point, therefore on bearing, a strong point can only be looked for dismantle when dismantling, therefore above-mentioned method all can cause certain damage to bearing temporarily; If axle and axis hole are fixed tight in addition, then easily loosening affects using effect.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides one and conveniently adds lubricant oil, avoids damaging bearing and being connected agricultural machinery roller bearing more closely with axle during dismounting.
The purpose of this utility model realizes by following technical proposal: a kind of agricultural machinery roller bearing, comprise bearing inner ring, outer race and the ring raceway be located between bearing inner ring and outer race, cylindrical rollers is provided with in described ring raceway, described bearing inner ring center is provided with axis hole, it is characterized in that: one end end face of described bearing inner ring has annular and protrudes, described protrusion is provided with at least one radial screw arranged, bolt is bolted with in described screw, some oil holes are provided with in described bearing inner ring, described oil hole one end is communicated with screw inside, run through between the oil hole the other end and ring raceway and be provided with oil duct, outside described oil duct one end and roller against, described some oil holes are by be located in bearing inner ring and the looping pit coaxial with bearing inner ring is connected, described roller inside has cavity, described roller is provided with duct, and cavity passing hole channel is connected with outside roller, sponge is provided with in described cavity, lubricating grease is adsorbed with in described sponge.
After inserting axle in axis hole, bearing and axle is fixed by bolt, therefore the tight fit connection of relatively traditional axle and axis hole, this connection is tightr, if desired lubricant oil is added, bolt is unclamped, afterwards oil filler pipe is inserted in screw and carries out oiling, because the screw the other end is subject to the stop of the axle be inserted in axis hole, therefore lubricant oil enters in ring raceway through oil hole and oil duct, and make lubricant oil cover in roller surface along the rotation of roller, avoid waste, as long as add lubricant oil in a screw, namely flow in each oil duct by looping pit, thus oiling better effects if, when dismantling bearing, will be screwed in screw with externally threaded extracting tool, and pulling along a direction extracting tool to get final product lower bearing for convenience detach afterwards, and avoid the extra dismounting strong point of finding to damage bearing, and roller inside has cavity, roller is provided with duct, and cavity passing hole channel is connected with outside roller, sponge is provided with in cavity, be adsorbed with lubricating grease in sponge, the roller therefore arranging hollow makes bearing radiating effect better, and when bearing is squeezed, also there is certain distortion leeway, prevent stuck.
In above-mentioned a kind of agricultural machinery roller bearing, described roller is provided with some ducts, and described oil duct is corresponding with described position, duct.
Therefore lubricant oil passing hole channel is facilitated to enter in cavity.
In above-mentioned a kind of agricultural machinery roller bearing, described roller is provided with circular base slab, and the described cavity described in dunnage separation, and dunnage central position is provided with through hole.
The effect that dunnage plays supporting roller is set.
In above-mentioned a kind of agricultural machinery roller bearing, described axis hole is square, and can insert square shaft in described axis hole.
In above-mentioned a kind of agricultural machinery roller bearing, four faces of described square opening and prism are provided with the screw described in four, and are all connected with oil hole in each screw.
In above-mentioned a kind of agricultural machinery roller bearing, described ring raceway both sides are provided with annular dust cover.
Compared with prior art, the utility model tool has the following advantages:
After inserting axle in axis hole, bearing and axle is fixed by bolt, therefore the tight fit connection of relatively traditional axle and axis hole, this connection is tightr, if desired lubricant oil is added, bolt is unclamped, afterwards oil filler pipe is inserted in screw and carries out oiling, because the screw the other end is subject to the stop of the axle be inserted in axis hole, therefore lubricant oil enters in ring raceway through oil hole and oil duct, and make lubricant oil cover in roller surface along the rotation of roller, avoid waste, as long as add lubricant oil in a screw, namely flow in each oil duct by looping pit, thus oiling better effects if, when dismantling bearing, will be screwed in screw with externally threaded extracting tool, and pulling along a direction extracting tool to get final product lower bearing for convenience detach afterwards, and avoid the extra dismounting strong point of finding to damage bearing, and roller inside has cavity, roller is provided with duct, and cavity passing hole channel is connected with outside roller, sponge is provided with in cavity, be adsorbed with lubricating grease in sponge, the roller therefore arranging hollow makes bearing radiating effect better, and when bearing is squeezed, also there is certain distortion leeway, prevent stuck.
