Abstract
The utility model relates to an arc-shaped cage packet retainer which is provided with a retainer (1) and cage packets (2) uniformly distributed on the retainer, wherein the retainer (1) is in an integral structure, and the cage packets (2) uniformly distributed on the retainer (1) are in the shape of an arc. The utility model is characterized in that the rolling body is accurately guided to guarantee the smooth and steady running of a bearing and reduce the running noise, and the lubricant grease can be easily added to obtain a favorable lubricating effect without excessive abrasion and the excessive heating of the retainer under the condition of high speed running; the integral retainer has good balance property and rigidity and has high load capacity, the sizes of rollers are enlarged, and the number of the rollers are increased; the cage packets are in the shape of an arc and have the function of self-locking measure to guarantee that the rollers can not slip after arranged and can be separated under the action of a proper force for periodical detecting test; the alleviation stress for processing a big arc on the corner is concentrated; the service life is long.
Description
Affiliated technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of arc pocket hole integral cage.
Background technique
At present, the cylinder roller bearing retainer manufactured of China mainly contains steel riveted joint two halves retainer, whole pulling eye retainer and two pockets hole and carries the rivet retainer.Because these retainers are still continued to use traditional mode on production technology and structural type, thereby all come with some shortcomings, rivet the deficiency that the two halves retainer exists rivet easily to become flexible, fracture as steel in the bearing application process; There is the deficiency of heating, wearing and tearing in whole pulling eye retainer; Two pockets hole carries the rivet retainer and exists and to be unfavorable for the deficiency dismantling, check.Not only have a strong impact on the usability of bearing, and shorten the working life of bearing.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of arc pocket hole integral cage.This retainer has runnability and the greasy property of improving rolling bearing, improves the intensity and the wear resistance of retainer, guarantees that rolling element accurately guides, prolongs the bearing characteristics in working life.
For achieving the above object, the utility model is achieved through the following technical solutions: retainer is an overall structure, and uniform pocket hole shape is a circular arc on its retainer.
The utlity model has following characteristics:
1, rolling element accurately guides.Both can guarantee that bearing operation was steady, reduce running noise, and add lubricating grease again easily, lubrication effect is good, under the condition of running up, the excessive heating of retainer excessive wear and bearing can not take place.
2, integral cage balance and rigidity are good.
3, integral cage has the high load capacity, and the roller size is increased, and quantity increases.
4, the pocket hole is an arc, has the hold depth of carrying function, both can guarantee roller pack into after not slippage, also can under the certain force effect, separate, so that defect detecting test regularly.
5, corner orthodrome processing relieve stresses is concentrated.
6, long service life.Good riding quality has prolonged the working life of bearing greatly, can improve 3-4 doubly.

Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is an accompanying drawing 1A-A sectional view.
Accompanying drawing 3 is that accompanying drawing 1B is to view.
Among the figure, 1, retainer, 2, the pocket hole, 3, lintel, 4, the lock point.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
In conjunction with Fig. 2, shown in Figure 3, present embodiment retainer 1 is an overall structure as accompanying drawing 1, and the shape that the pocket hole 2 of roller is placed in uniform being used on it is circular arc.Be lintel 3 between pocket hole and the pocket hole.The lock point 4 that has protrusion on the outer diametric plane in circular arc pocket hole comes off in order to prevent roller.Lock point on each pocket hole is 4.
Claims (2)
1, a kind of arc pocket hole integral cage has retainer (1) and is distributed on pocket hole (2) on the retainer (1), and it is characterized in that: described retainer (1) is overall structure, and uniform pocket hole (2) on it is shaped as circular arc.
2, arc pocket according to claim 1 hole integral cage is characterized in that: the lock point (4) that has protrusion on the outer diametric plane of pocket hole (2).
