Description
Technical field
The invention belongs to farm machinery parts technical field, relate 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 object of the invention is for the above-mentioned problems in the prior art, provide one and conveniently add lubricant oil, avoid damaging bearing and being connected agricultural machinery roller bearing more closely with axle during dismounting.
Object of the present invention 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 protrusion outer circumferential face is provided with outside thread.
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, arbitrary 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, first bolt all being screwed out, female for band tubular extracting tool being screwed to and protruding on outer circumferential face, pull along a direction extracting tool to get final product lower bearing for convenience detach afterwards, avoid the extra dismounting strong point of finding to damage bearing.
In above-mentioned a kind of agricultural machinery roller bearing, the symmetrical structure of described bearing, and the two ends end face of bearing inner ring is equipped with symmetrical annular protrusion, and be equipped with screw on protruding, all be connected with one end of oil hole in each screw, and the protrusion outer circumferential face at two ends is equipped with outside thread.
Bilateral symmetry conveniently can select oil filler pipe insertion position according to actual conditions is set, and the position that extracting tool is arranged.
In above-mentioned a kind of agricultural machinery roller bearing, described screw is provided with groove on protrusion outer circumferential face, and described bolt is spirally connected in screw, and bolt head is located in described groove.
Be located at by bolt head in groove, when avoiding bearing to rotate, bolt collides with outside.
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.
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, tool of the present invention 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, arbitrary 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, first bolt all being screwed out, female for band tubular extracting tool being screwed to and protruding on outer circumferential face, pull along a direction extracting tool to get final product lower bearing for convenience detach afterwards, avoid the extra dismounting strong point of finding to damage bearing.
