Description
Technical field:
The present invention relates to a kind of four-point contact balls, more particularly to a kind of novel four point contact with split type retainer
Ball bearing.
Background technique:
Currently, mostly using ball formula integral cage for the four-point contact ball of non-horizontal mounting.The retainer of the structure
Since four-point contact ball structure size limits, holder thinner thickness is designed.Retainer often goes out in process
Existing oval larger phenomenon, when installation, need to carry out shaping to retainer.It nonetheless, also can be with after the retainer installation of shaping
Frictional interference causes finished product torque overproof between the outer internal diameter of bearing and internal-and external diameter.
Summary of the invention:
The technical problems to be solved by the present invention are: overcoming the deficiencies of the prior art and provide, a kind of design is reasonable, reduces frictional force
Square and the novel four-point contact ball bearing with split type retainer for improving retainer guidance.
The technical scheme is that
A kind of novel four-point contact ball bearing with split type retainer, including inner ring, outer ring, retainer, steel ball, taper pin,
Plug and sealing are changed, and are formed four-point contact ball shape channel between the outer ring and inner ring, are machined among the channel of the inner ring
The annular square groove of bearing retainer is guided, the retainer uses several sections of circumference of separate structure, the annular is embedded in after combination
In square groove, the hole for accommodating steel ball is provided in the retainer along axial direction, when assembling, the retainer first passes through the annular square groove
Among the inner ring, after the steel ball is packed into the retainer from plug hole, the outer ring and inner ring limit the steel
Ball moves radially, while the steel ball limits moving radially for the retainer, after reset, the retainer and the inner ring
Annular square groove axially and radially have gap.
When operating, the retainer rotates under the drive of the steel ball, and the retainer has functioned well as isolation institute
State the effect of steel ball.The annular square groove of the retainer and the inner ring axially has the gap 0.8~1.2mm, radially have 0.4~
The gap of 0.6mm.
The beneficial effects of the present invention are:
1, the present invention is not changing original outer dimension, by optimizing four-point contact ball retainer structure, reaches reduction
The effect of bearing frictional torque.
2, in finished product operating, retainer rotates the present invention under the drive of steel ball, and retainer has functioned well as isolation
The effect of steel ball, this structure very good solution booting problem of retainer, while avoiding traditional structure retainer and axis
The frictional interference between internal-and external diameter and bearing internal external diameter is held, the moment of friction of bearing finished products is considerably reduced.
3, the present invention has rational design, reduce moment of friction and improves retainer guidance, unique structure, implementation easy to spread,
Implementation easy to spread, it is with good economic efficiency.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of four-point contact ball in the prior art.
Fig. 2 is the structural schematic diagram of the novel four-point contact ball bearing with split type retainer.
Specific embodiment:
Referring to Fig. 1-Fig. 2, in figure, the outer ring 1-, 2- inner ring, 3- retainer, 4- steel ball, 5- taper pin, 6- sealing ring, 7- plug.
Novel four-point contact ball bearing with split type retainer, including inner ring 2, outer ring 1, retainer 3, steel ball 4, cone
Pin 5, plug 7 and sealing ring 6.Four-point contact ball shape channel is formed between outer ring 1 and inner ring 2, is processed in bearing inner race channel
There is the annular square groove of guidance bearing retainer 3.Retainer 3 is embedded in bear inner ring grooved railway after combination using several sections of circumference of separate structure
In the annular square groove processed, the hole for accommodating steel ball 4 is provided in retainer 3 along axial direction.In retainer 3 first passes through when assembling product
The annular square groove of circle guidance retainer leans against among inner ring, after steel ball 4 is packed into retainer 3 from plug hole, due in bearing
Outer ring limits moving radially for steel ball 4, while steel ball 4 limits moving radially for retainer 3, after reset retainer 3 with it is interior
The annular square groove of circle 2 axially has the gap 0.8-1.2mm (specific value can take 0.8,0.9,1.0,1.2,1.2 etc.), radially has
The gap of 0.4-0.5mm (specific value can take 0.4,0.5,0.6 etc.).When finished product operates, drive of the retainer 3 in steel ball 4
Lower rotation, retainer 3 have functioned well as the effect of isolation steel ball 4.The guidance of this structure very good solution retainer is asked
Topic, while the frictional interference between traditional structure retainer and bearing internal external diameter and bearing internal external diameter is avoided, it greatly reduces
The moment of frictions of bearing finished products.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, it is all
It is any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the invention, still falls within
In the range of technical solution of the present invention.
