Description
Technical field
The invention belongs to farm machinery parts technical field, relate to a kind of agricultural machinery roller bearing.
Background technology
Bearing is to play parts that are fixing and that reduce load coefficient of friction in mechanical transmission course.It may also be said that when other parts produce relative motion each other on axle, be used for the coefficient of friction reducing in power transmission process and the parts keeping axle center fixing.Bearing is a kind of very important parts in plant equipment in the present age.
It is all add lubricating oil by the fuel filler neck on bearing block in bearing that traditional bearing adds lubricating oil, to be filled into inside the ball between bearing inner ring and outer race relatively difficult during oiling, lubricating oil can flow everywhere and can not arrive ball place, so not only cause waste, be also easy to cause bearing damage because lubricating oil is not enough.And the method for dismounting of bearing mainly has hammering method, pushing method and heat to tear method open at present, owing to lacking the strong point, therefore a strong point can only being looked on bearing to dismantle when dismounting, therefore above-mentioned method all countershaft can manufacture into certain damage temporarily；If additionally axle is fixing with axis hole not tight, then easily loosens and affect result of use.
Summary of the invention
It is an object of the invention to for the above-mentioned problems in the prior art, it is provided that one facilitates oil addition, it is to avoid damage bearing during dismounting and be connected agricultural machinery roller bearing more closely with axle.
nullThe purpose of the present invention can be realized by following technical proposal: a kind of agricultural machinery roller bearing，Including bearing inner ring、Outer race and be located at the ring raceway between bearing inner ring and outer race，It is provided with cylindrical rollers 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 protrusion，Described protrusion is provided with at least one screw being radially arranged，It is bolted with bolt in described screw，Some oil filler points it are provided with in described bearing inner ring，Described oil filler point one end is internal with screw to be connected，Run through between the oil filler point other end and ring raceway and be provided with oil duct，Outside described oil duct one end and roller against，Described some oil filler points pass through to be located in bearing inner ring and the looping pit coaxial with bearing inner ring is connected，Described protrusion outer peripheral face is provided with external screw thread.
After axis hole is inserted into axle, bearing and axle it is fixed by bolt, therefore the tight fit connection of relatively conventional axle and axis hole, this connection is tightr, if desired oil addition, arbitrary bolt is unclamped, afterwards oil fuel tube is inserted in screw and carries out oiling, owing to the screw other end is subject to the stop of the axle being inserted in axis hole, therefore lubricating oil enters in ring raceway through oil filler point and oil duct, and make lubricating oil cover in roller surface along the rotation of roller, avoid waste, as long as adding lubricating oil in a screw, can by looping pit stream to each oil duct, thus refueling better effects if；When dismantling bearing, first bolt is all screwed out, female for band tubular extracting tool is screwed on protrusion outer peripheral face, pulls extracting tool can conveniently dismantle lower bearing along a direction afterwards, it is to avoid the extra dismounting strong point of finding damages 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 it is equipped with screw on protruding, it is respectively connected with one end of oil filler point in each screw, and the protrusion outer peripheral face at two ends is equipped with external screw thread.
The position that bilateral symmetry conveniently can select oil fuel tube to insert according to practical situation and the position that extracting tool is arranged are set.
In above-mentioned a kind of agricultural machinery roller bearing, described screw is provided with groove on protrusion outer peripheral face, and described bolt is spirally connected in screw, and bolt head is located in described groove.
Being located in groove by bolt head, it is to avoid when bearing rotates, 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 four described screws.
In above-mentioned a kind of agricultural machinery roller bearing, described ring raceway both sides are provided with annular dust cap.
Compared with prior art, present invention have the advantage that
After axis hole is inserted into axle, bearing and axle it is fixed by bolt, therefore the tight fit connection of relatively conventional axle and axis hole, this connection is tightr, if desired oil addition, arbitrary bolt is unclamped, afterwards oil fuel tube is inserted in screw and carries out oiling, owing to the screw other end is subject to the stop of the axle being inserted in axis hole, therefore lubricating oil enters in ring raceway through oil filler point and oil duct, and make lubricating oil cover in roller surface along the rotation of roller, avoid waste, as long as adding lubricating oil in a screw, can by looping pit stream to each oil duct, thus refueling better effects if；When dismantling bearing, first bolt is all screwed out, female for band tubular extracting tool is screwed on protrusion outer peripheral face, pulls extracting tool can conveniently dismantle lower bearing along a direction afterwards, it is to avoid the extra dismounting strong point of finding damages bearing.
