Abstract
The utility model belongs to technical field of bearings, it is related to a kind of mute retainer of bearing, including circular retainer body, several spacing blocks are uniformly arranged on retainer body, pocket hole is formed between two neighboring spacing block, the bottom surface in pocket hole is the first cambered surface, and the side in pocket hole is cylindrical surface, the upper end opening both sides in pocket hole are respectively formed a fore shaft portion, and the inner surface in fore shaft portion forms the second cambered surface.The utility model product is improved design by the structure to retainer, efficiently solves the problems, such as the abnormal sound of bearing, can effectively substitute imported bearing using the bearing of the utility model product, reduce the use cost of enterprise；The raceway guidance mode of the utility model product and oil storage effect obtain larger improvement simultaneously.
Description
Technical field
The utility model belongs to technical field of bearings, is related to a kind of mute 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-precision, 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
Abnormal noise is can't hear in requirement during survey, and it is exactly straight line to see that oscillography is shown.The bearing required like this we defined
It is the mute 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 into
The main reason for mouth bearing, the muting function for influencing motor bearings, is to maintain the structure of frame, and bearing producer is mute 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
In view of the above-mentioned problems, providing a kind of mute retainer of bearing, which can effectively solve the utility model
The abnormal sound problem of bearing.
According to the technical solution of the utility model：A kind of mute retainer of bearing, including circular retainer body,
It is characterized in that：Several spacing blocks are uniformly arranged on retainer body, pocket hole, the bottom in pocket hole are formed between two neighboring spacing block
Face is the first cambered surface, and the side in pocket hole is cylindrical surface, and the upper end opening both sides in pocket hole are respectively formed a fore shaft portion, fore shaft portion
Inner surface forms the second cambered surface.
As further improvement of the utility model, a steel ball, the central point and pocket of steel ball are placed in each pocket hole
There is eccentric distance e between the center of circle in hole.
As further improvement of the utility model, groove is formed between two fore shaft portions on same spacing block.
As further improvement of the utility model, the outer ring in fore shaft portion sets the first chamfering, and the inner ring in fore shaft portion is set
Second chamfering.
The utility model has technical effect that：The utility model product is improved by the structure to retainer and set
Meter, efficiently solves the problems, such as the abnormal sound of bearing, imported bearing can be effectively substituted using the bearing of the utility model product, reduces
The use cost of enterprise；The raceway guidance mode of the utility model product and oil storage effect obtain larger improvement simultaneously.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is sectional view along A-A in Fig. 1.
Fig. 3 is enlarged drawing at M in Fig. 1.
Specific embodiment
Specific embodiment of the present utility model 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, cylindrical surface 13 etc..
As shown in Fig. 1 ~ 3, the utility model is a kind of mute retainer of bearing, including circular retainer body 2, is protected
It holds and several spacing blocks 12 is uniformly arranged on frame body 2, pocket hole 5 is 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 cylindrical surface 13, and the upper end opening both sides in pocket hole 5 are respectively formed a fore shaft portion 8, fore shaft
The inner surface in portion 8 forms the second cambered surface 9.
A steel ball 1 is placed in each pocket hole 5, there is eccentricity 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 the utility model product in specific manufacture, the width on the cylindrical surface 13 in pocket hole 5 is typically designed as steel ball 1 directly
0.382 times of footpath, 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
For the diameter of steel 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
Ball is easily embraced, the shifting amount of ball is too big, and vibration is too big, easily generates abnormal sound；The material of retainer body 2 is usually with can be molded
High-strength nylon material or PEEK（Polyether-ether-ketone）Material.
