Description
Technical field
The utility model belongs to technical field of bearings, refers in particular to a kind of high-wearing feature bearing track.
Background technique
Bearing is a kind of important spare part in contemporary mechanical equipment, its major function is to support mechanical rotary body, is reduced
Coefficient of friction in its motion process, and guarantee its rotating accuracy, since amount of heat, high temperature can be generated in bearing rotation process
Under state, the wearability of bearing can decline, it is therefore desirable to which bearing arrangement is further improved.
Utility model content
The purpose of the utility model is to provide a kind of high-wearing feature bearing tracks of easy heat radiation.
Purpose of the utility model is realized as follows: a kind of high-wearing feature bearing track, it is characterised in that: including upper rail
Road and lower railway are equipped with the track groove in evagination arcuate structure on the upper and lower track that gets on the right track, are equipped between two track grooves
Ball, track groove include binding face and the radiating surface for being placed in binding face two sides, and binding face and ball contradict, radiating surface and ball it
Between be equipped with heat dissipation gap, the caulking groove of structure in a ring is additionally provided on binding face, is equipped with the insert contradicted with ball, insert in caulking groove
Several microcellular structures are equipped with, several microcellular structures are interconnected and form oil storage channel.
By using above-mentioned technical proposal, binding face and radiating surface also arc-shaped structure, due between radiating surface and ball
With heat dissipation gap, convenient for the heat dissipation in ball rolling process, after insert is embedded in caulking groove, the one side knot of insert and ball conflict
Structure is identical as binding face structure, and insert is sintered by iron-based powder, has microcellular structure after forming it, and at insert immersion oil
Reason, when rolling friction between ball and insert when heat, the hole in insert increases, and lubricating oil can overflow, and plays lubrication effect
Fruit and heat can be reduced, improve the wear-resisting property of bearing track.
The utility model is further arranged to: the insert is equipped with oil storage annular groove, oil storage annular groove away from the one side of ball
It is connected with oil storage channel.
By using above-mentioned technical proposal, before use, upper rail and insert need to immerse in oil groove, so that insert and oil storage
The abundant oil suction of annular groove increases oil reserve.
The utility model is further arranged to: it is described upper rail and lower railway material be 75CrV chrome-vanadium steel.
By using above-mentioned technical proposal, 75CrV chrome alum steel hardenability is higher, and hardness can reach HRC55-60, improves
Intensity and toughness, and have the characteristics that high-wearing feature, shock resistance be strong, antidetonation, promote durable, endurance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-sectional view of the utility model；
Fig. 3 is the portion the A enlarged structure schematic diagram of the utility model Fig. 2；
Appended drawing reference in figure are as follows: 1, upper rail；2, lower railway；3, ball；4, binding face；5, radiating surface；6, insert；7, it stores up
Oil ring groove.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-3:
A kind of high-wearing feature bearing track, it is characterised in that: including upper rail 1 and lower railway 2, get on the right track 1 upper and lower rail
It is equipped with the track groove in evagination arcuate structure on road 2, is equipped with ball 3 between two track grooves, track groove includes 4 He of binding face
It is placed in the radiating surface 5 of 4 two sides of binding face, binding face 4 and ball 3 contradict, and heat dissipation gap, patch are equipped between radiating surface 5 and ball 3
It is additionally provided with the caulking groove of structure in a ring on conjunction face 4, the insert 6 contradicted with ball 3 is equipped in caulking groove, insert 6 is equipped with several micro-
Pore structure, several microcellular structures are interconnected and form oil storage channel.
By using above-mentioned technical proposal, binding face 4 and radiating surface 5 also arc-shaped structure, due to radiating surface 5 and ball 3
Between there is heat dissipation gap, convenient for the heat dissipation in 3 rolling process of ball, after insert 6 is embedded in caulking groove, insert 6 and ball 3 are contradicted
One side structure it is identical as 4 structure of binding face, insert 6 is sintered by iron-based powder, make its form after have microcellular structure, and
The processing of 6 immersion oil of insert, when rolling friction between ball 3 and insert 6 when heat, the hole in insert 6 increases, and lubricating oil can overflow
Out, lubricant effect is played, the wear-resisting property of bearing track is improved.
The utility model is further arranged to: the insert 6 is equipped with oil storage annular groove 7, oil storage ring away from the one side of ball 3
Slot 7 is connected with oil storage channel.
By using above-mentioned technical proposal, before use, upper rail 1 and insert 6 need to immerse in oil groove, so that 6 He of insert
The abundant oil suction of oil storage annular groove 7 increases oil reserve.
The utility model is further arranged to: it is described upper rail 1 and 2 material of lower railway be 75CrV chrome-vanadium steel.
By using above-mentioned technical proposal, 75CrV chrome alum steel hardenability is higher, and hardness can reach HRC55-60, improves
Intensity and toughness, and have the characteristics that high-wearing feature, shock resistance be strong, antidetonation, promote durable, endurance.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
