Description
Technical field
The invention belongs to technical field of bearings, is related to a kind of crossed cylindrical roller retainer.
Background technology
Crossed cylindrical roller bearing is mainly used in robot swivel base, and it is mainly characterized by required precision height, holds
Big by sideshake torque, traditional retainer structure is to be entered between cross one another cylindrical roller and roller with nylon spacer
Row isolation, the problem of existing be：1, difficult when bearing assembles, the spacer between crossed roller and roller is artificial one one
It is loaded into, and the aobvious dress that is easy to is random, while spacer and cylindrical roller are easy to fall apart during bearing cleaning, influence batch
The progress of production.2 be the spacer of one one during bearing working, the mutually collision between this of spacer and cylindrical roller,
Service life reduces, and influences the use of bearing.
The content of the invention
For the present invention in view of the above-mentioned problems, providing a kind of crossed cylindrical roller retainer, the retainer will be original scattered
Spacer be integrated into an integral cage, improve the assembling effect and using effect of bearing.
According to technical scheme：A kind of crossed cylindrical roller retainer, it is characterised in that：Including ring-type
Retainer body, the outer surface of the retainer body form a circle exterior protrusion, and the inner wall surface of retainer body forms one
Enclose internal projection portion；Some first cylindrical roller holes are uniformly arranged on exterior protrusion, are divided between two neighboring first cylindrical roller hole
Not She Zhi a second cylindrical roller hole, the first cylindrical roller hole is mutually perpendicular to both the second cylindrical roller hole axis, and
One cylindrical roller hole penetrates with the second cylindrical roller hole and extends to internal projection portion.
As a further improvement on the present invention, angle is sharp between the first cylindrical roller hole upper end and retainer body
Angle.
As a further improvement on the present invention, the exterior protrusion includes outside ramp and outside lower inclined plane, on outside
Intersect with outside lower inclined plane on inclined-plane；The internal projection portion includes inner side ramp and inner side lower inclined plane, inner side ramp and inner side
Lower inclined plane intersects；The first cylindrical roller hole upper end is intersected with outside ramp, under the first cylindrical roller hole lower end and inner side
Inclined-plane intersects, and the second cylindrical roller hole upper end is intersected with inner side ramp, the second cylindrical roller hole lower end and outside lower inclined plane phase
Hand over.
The technical effects of the invention are that：The retainer of product of the present invention is according to the service condition of user and setting for product
Meter is required to improve existing retainer, and former scattered spacer is integrated into an integral cage, improves axle
The assembling effect and using effect held；Product of the present invention outer ring in use and inner ring form an assembly, it is ensured that bearing exists
Roller and retainer will not fall apart during assembling, cleaning and use.
Brief description of the drawings
Fig. 1 is the stereogram of the present invention.
Fig. 2 is the front view of the present invention.
Fig. 3 is Fig. 2 top view.
Fig. 4 is Fig. 2 left view.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1 ~ 4, including it is retainer body 1, the first cylindrical roller hole 2, the second cylindrical roller hole 3, exterior protrusion 4, interior
Lug boss 5 etc..
As shown in Fig. 1 ~ 4, the present invention is a kind of crossed cylindrical roller retainer, includes the retainer body 1 of ring-type,
The outer surface of the retainer body 1 forms a circle exterior protrusion 4, and the inner wall surface of retainer body 1 forms a circle internal projection
Portion 5；Some first cylindrical roller holes 2 are uniformly arranged on exterior protrusion 4, are set respectively between two neighboring first cylindrical roller hole 2
A second cylindrical roller hole 3 is put, the first cylindrical roller hole 2 is mutually perpendicular to second both axis of cylindrical roller hole 3, and first
The cylindrical roller hole 3 of cylindrical roller hole 2 and second, which penetrates, extends to internal projection portion 5.
Angle is acute angle between the upper end of first cylindrical roller hole 2 and retainer body 1.
Exterior protrusion 4 includes outside ramp and outside lower inclined plane, and outside ramp intersects with outside lower inclined plane；In described
Lug boss 5 includes inner side ramp and inner side lower inclined plane, and inner side ramp intersects with inner side lower inclined plane；First cylindrical roller
The upper end of hole 2 is intersected with outside ramp, and the lower end of the first cylindrical roller hole 2 is intersected with inner side lower inclined plane, on the second cylindrical roller hole 3
End is intersected with inner side ramp, and the lower end of the second cylindrical roller hole 3 is intersected with outside lower inclined plane.
Product of the present invention in assembling in use, only need to pack into retainer into the inner ring of bearing, then by 1 peace of roller 1
It is attached on retainer, at this moment, cylindrical roller, inner ring and retainer form an assembly, so that it is guaranteed that bearing is in assembling, clear
Wash and use during roller and retainer will not fall apart；Retainer body 1 is in design, the face of cylinder of cylindrical roller and guarantor
Hold and bootstrap 0.1 ~ 0.3mm of gap is kept between the cylindrical hole of frame.
Product of the present invention is widely used in robot swivel base, has precision high, it is big to bear sideshake torque
The advantages of.
