Description
Technical field
A kind of bearing, more particularly to a kind of sprocket shaft bearing are the utility model is related to, belongs to technical field of bearings.
Background technology
Conventional sprocket shaft bearing, at work, it is outer ring rotation, radial load is born by outer ring external diameter, thus
The design having different from conventional deep groove ball bearing of sprocket shaft bearing is sought, this class bearing there are following several knots under normal circumstances
Structure：Single-row ball-bearing, row ball bearing, double-row angular contact bal bearing.As shown in Fig. 2 the sprocket shaft bearing of prior art includes outer ring
7th, inner ring 8, retainer 9, steel ball 10, sealing ring 13.The class bearing only increases steel ball size and steel when bearing compared with big load
Ball number, the bearing capacity of bearing could be improved, the volume for so resulting in bearing becomes big, and not only waste of materials, processes labor intensive,
And fork truck volume will also increase, bigger waste is caused, can not meet the demand in market.
Utility model content
The purpose of this utility model is to provide a kind of sprocket shaft bearing, under identical appearance size, can bear big radial direction
Load, axial load have longer service life with shock loading.
A kind of sprocket shaft bearing, including overcoat, outer ring, inner ring, steel ball, sealing ring, back-up ring；Overcoat is ring-type type component,
It is provided with an inner bore of step, and a circlip groove is provided with close to end in the macropore of inner bore of step, and outer ring loads from one end of overcoat,
The macropore of the inner bore of step of the cylindrical and overcoat of outer ring is engaged, and a side end face of outer ring is leaned against at the inner face of inner bore of step,
Inner ring is arranged in the endoporus of outer ring, is equipped with corresponding raceway groove in cylindrical, outer ring the endoporus of inner ring, steel ball sets raceway groove
Interior, the both sides end face of outer ring is respectively provided with a sealing ring, and cylindrical, outer ring endoporus, the steel ball sealing of inner ring are lived, and back-up ring is set
In circlip groove, back-up ring fixes outer ring.
The utility model is further realized by following scheme：
A kind of foregoing sprocket shaft bearing, overcoat uses GCr15 materials, and passes through Tempering and Quenching.
A kind of foregoing sprocket shaft bearing, raceway groove use double row angular contact.
The groove curvature coefficient of a kind of foregoing sprocket shaft bearing, outer ring and inner ring is respectively 0.515,0.510.
A kind of foregoing sprocket shaft bearing, inner ring is using plating Zn/Ni alloys.
Bearing outside of the present utility model uses GCr15, conditioned heat treatment, has high intensity and good wilfulness, punching
Hit performance；Raceway groove uses double row angular contact, can not only bear radial load, can also bear axial load；Outer ring and inner ring
Groove curvature coefficient be respectively 0.515,0.510, the adaptation of steel ball and bearing channel is improved, so as to improve bearing
Bearing capacity；Inner ring is improved the frictional behaviour of inner ring and axle, is reduced the bonding of axle and inner ring, increased using plating Zn/Ni alloys
The wriggling of bearing, so as to improve the bearing capacity of bearing；Due to using full spherical structure, the steel ball size of formed objects, steel ball quantity
Amount is more than the sprocket shaft bearing of original structure, so as to improve the bearing capacity of bearing.Increase an axle sleeve on outer ring, can
Bearing volume is reduced, when bearing needs to change, only need to change outer ring and inner ring, it is cost-effective.
The advantages of the utility model and feature, diagram reconciliation will be carried out by the non-limitative illustration of preferred embodiment below
Release, these embodiments, only provide as an example referring to the drawings.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is the front view of this prior art.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model includes overcoat 1, outer ring 2, inner ring 3, steel ball 4, sealing ring 5, back-up ring 6；Overcoat 1 is
Ring-type type component, overcoat 1 uses GCr15 materials, and passes through Tempering and Quenching, and it is provided with an inner bore of step 11, in step
The macropore in hole 11 is provided with a circlip groove 12 close to end, and outer ring 2 loads from the left side of overcoat 1, the cylindrical and overcoat 1 of outer ring 2
The macropore of inner bore of step 11 be engaged, its right end face of outer ring 2 is leaned against at the inner face of inner bore of step 11, and inner ring 3 is arranged on
In the endoporus of outer ring 2, inner ring 3 is equipped with corresponding ditch using plating Zn/Ni alloys in cylindrical, outer ring 2 the endoporus of inner ring 3
Road 21, raceway groove 21 use double row angular contact, and the coefficient of curvature of raceway groove 21 of outer ring 2 and inner ring 3 is respectively 0.515,0.510, steel ball 4
Set in raceway groove 21, the both sides end face of outer ring 2 is respectively provided with a sealing ring 5, by cylindrical, outer ring 2 endoporus, the steel ball 4 of inner ring 3
Seal up, back-up ring 6 is arranged in circlip groove 12, and back-up ring 6 fixes outer ring 2.
In addition to the implementation, the utility model can also have other embodiment, all to use equivalent substitution or equivalent change
The technical scheme to be formed is changed, is all fallen within the protection domain of the requires of the utility model.
