Description
Technical field
The utility model relates to a kind of tapered roller bearing more particularly to a kind of abnormal shape with gluing retaining ring are non-maintaining single-row
Tapered roller bearing.
Background technique
Single-row tapered roller bearing with retaining ring, usually by cup, cone, roller, retainer and retaining ring etc.
Part is constituted.
Single-row tapered roller bearing, has that structure is simple, production cost is low, it is flexible and convenient to install and use, at the same have with
Based on radial carrying, the advantages that being unidirectionally axially carried as auxiliary sharing lood ability.Relative to ball bearing, it is big to have both bearing capacity
Advantage, therefore be the great bearing type of modern manufacturing industry demand.
The single-row tapered roller bearing outer ring raceway of conventional structure is a tapered surface, only unidirectional axial carrying energy
Power.It is carried if you need to bi-directional axial, it is necessary to which mounted in pairs uses double-row bearing.But the bearing of mounted in pairs can be related to end-play
Adjustment, to operator and installation equipment have higher requirements.Once end-play adjustment is improper, bearing life can drop significantly
It is low.And mounted in pairs or double-row bearing are used, also suffer from the limitation of installation space.
In addition, not grease up when the single-row tapered roller bearing factory of conventional structure, by user in fixing link
Filling and later maintenance link are added.The two links are likely to introduce the impurity such as hard particles, and bearing life is caused to reduce,
And increase workload.
The rotation of conventional structure single-row tapered roller bearing, roller is supported mainly by inner ring large-flange plane.Due to inner ring
Large-flange plane is wider, and is sliding friction with roller ball basal plane, causes bearing rotating torque to increase, serious, the limit turn of generating heat
Speed reduces, the lost of life.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, provides a kind of solution traditional structure spline docking
There is the band for the problems such as gap, installation are complicated, driving moment loss is big, output torque is small, and component weight is heavy, fuel economy is low
The non-maintaining single-row tapered roller bearing of abnormal shape of gluing retaining ring.
Above technical problems of the utility model are mainly solved by the following technical scheme:
A kind of non-maintaining single-row tapered roller bearing of abnormal shape with gluing retaining ring, including inner ring and outer ring, the inner ring
Several rollers are equipped between outer ring, the roller is positioned by retainer, and the tail portion of the outer ring is kept off equipped with gluing
Circle；
The upper end of the gluing retaining ring left side wall is adhesive surface, and the middle-end of the gluing retaining ring left side wall is step
Face, the lower end of the gluing retaining ring left side wall are supporting surface.
Preferably, the step depth of the step surface is 0.9mm, the supporting surface and radial direction are at 12 ° of angles；Institute
The supporting surface and roller big end spacing for the gluing retaining ring stated are 0.46mm；The gluing retaining ring internal diameter and retainer outer diameter spacing
Unilateral is 0.7mm.
Solve following problems:
1, since conventional structure single-row tapered roller bearing only has unidirectional axial carrying capacity, have to be chosen to
To installation or double-row bearing.For the single-row bearing of mounted in pairs, have causes bearing life to reduce because clearance adjustment is improper
Risk；And either way by the very big limitation of installation space, while increasing cost.
2, user may make foreign matter enter bearing, bearing life is caused to reduce in grease up and later maintenance.
3, due to the sliding friction of inner ring large-flange and roller big end ball basal plane, cause bearing rotating torque it is larger, high turn
The lower fever of speed is serious, and bearing life reduces.
(1) main innovation point:
1, the gluing retaining ring with supporting surface is designed, using special process, using special glue by outer ring facet and gluing
Retaining ring step surface is bonded, and is integrally formed the two securely, and the rotation for taper roller large end face supports；It designs simultaneously
Inner ring with small rib supporting surface, the rotation for taper roller small end face support.
2, preset end-play solves single-row tapered roller bearing due to clearance tune without adjusting clearance when user's use
Whole improper the problem of causing bearing life to reduce.
3, lubricating grease is infused in advance, and foreign matter enters bearing when reducing due to bearing installation and later maintenance link grease adding
The risk for causing bearing life to reduce, has been really achieved non-maintaining effect.
4, design reduces sliding friction without large-flange inner ring, reduces bearing rotating torque, improve bearing limit speed and
Service life.
Technical indicator:
1, it the bench simulation test service life: " rolling bearing life and reliability test and is commented by GB/T 24607-2009
It is fixed ", >=3 times of L10Service life.
2, after gluing retaining ring bonding, the anti-pulling-out force between outer ring: >=200N.
Economic indicator:
Monthly output is up to 15000 sets or more；Year volume increase value is 5,000,000 yuan or more.
Therefore, the non-maintaining single-row tapered roller bearing of abnormal shape with gluing retaining ring of the utility model, it is compact-sized, it is promoted
Service performance.
