Description
Technical field
The invention belongs to technical field of bearings, it is related to a kind of Jing Yin retainer of bearing.
Background technology
Robot servomotor is mainly characterized by required precision height at present, and rotating speed is high, motor is surveyed in high-speed rotation
The noise requirements sound without exception of complete machine is tried, this also requires used bearing to adapt to such high speed, high accuracy, be no different
The requirement of sound, through carrying out test analysis to satisfactory bearing, bearing is examined with vibration velocity type and vibration acceleration type instrument
Require to can't hear abnormal noise during survey, it is exactly straight line to see that oscillography is shown.The bearing required like this we defined
It is the Jing Yin bearing of servomotor, is applied to the domestic and international quality difference of bearing on servomotor at present apart from very big, upper quality
Servomotor manufacturer to domestic bearing still feel doubt throb with fear thus in more than 80% servomotor factory or using enter
Mouthful bearing, the structure of frame is to maintain the main reason for the muting function for influenceing motor bearings, bearing producer is Jing Yin in bearing at present
The existing corresponding research of retainer, also achieves certain effect, but with foreign brand name bearing its muting function also have one
Fixed gap.
The content of the invention
For the present invention in view of the above-mentioned problems, providing a kind of Jing Yin retainer of bearing, the holder can effectively solve bearing
Abnormal sound problem.
According to technical scheme：A kind of Jing Yin retainer of bearing, including circular retainer body, its feature
It is：Several spacing blocks are uniformly arranged on retainer body, form pocket hole between two neighboring spacing block, the bottom surface in pocket hole is
First cambered surface, the side in pocket hole is the face of cylinder, and the upper end open both sides in pocket hole form a fore shaft portion, the inner side in fore shaft portion respectively
Surface forms the second cambered surface.
As a further improvement on the present invention, a steel ball, central point and the pocket hole of steel ball are placed in each pocket hole
There is eccentric distance e between the center of circle.
As a further improvement on the present invention, groove is formed between two fore shaft portions on same spacing block.
As a further improvement on the present invention, the outer ring in fore shaft portion sets the first chamfering, and the inner ring in fore shaft portion sets second
Chamfering.
The technical effects of the invention are that：Product of the present invention is effectively solved by being improved design to the structure of retainer
Determined the abnormal sound problem of bearing, imported bearing can effectively be substituted using the bearing of product of the present invention, reduce the use of enterprise into
This；The raceway guidance mode of product of the present invention and oil storage effect obtain larger improvement simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 be in Fig. 1 A-A to sectional view.
Fig. 3 is enlarged drawing at M in Fig. 1.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1 ~ 3, including steel ball 1, retainer body 2, the center of circle 3, the first chamfering 4, pocket hole 5, central point 6, the second chamfering
7th, fore shaft portion 8, the second cambered surface 9, the first cambered surface 10, groove 11, spacing block 12, face of cylinder 13 etc..
As shown in Fig. 1 ~ 3, the present invention is a kind of Jing Yin retainer of bearing, including circular retainer body 2, retainer
Several spacing blocks 12 are uniformly arranged on body 2, pocket hole 5 are formed between two neighboring spacing block 12, the bottom surface in pocket hole 5 is first
Cambered surface 10, the side in pocket hole 5 is the face of cylinder 13, and the upper end open both sides in pocket hole 5 form a fore shaft portion 8 respectively, fore shaft portion 8
Inner surface forms the second cambered surface 9.
A steel ball 1 is placed in each pocket hole 5, there is eccentric throw between the central point 6 of steel ball 1 and the center of circle 3 in pocket hole 5
e。
Groove 11 is formed between two fore shaft portions 8 on same spacing block 12.
The outer ring in fore shaft portion 8 sets the first chamfering 4, and the inner ring in fore shaft portion 8 sets the second chamfering 7.
For product of the present invention in specific manufacture, the width on the face of cylinder 13 in pocket hole 5 is typically designed as the diameter of steel ball 1
0.382 times, cylinder it is too wide or it is too narrow can all influence vibration and noise；Eccentric distance e is designed as（0.010-0.02）* Dw, Dw are steel
The diameter of ball 1, the design of eccentric distance e can reduce the radial-play amount of retainer body 2, and the shifting amount of steel ball 1 is too small easy
Ball is embraced, the shifting amount of ball is too big, and vibration is too big, easily produces abnormal sound；The material of retainer body 2 is usually the height that use can be molded
Strength nylon material or PEEK（Polyether-ether-ketone）Material.
