Description
Technical field
The utility model relates to a kind of ball retainers.
Background technique
Ball retainer is and on its outer round surface, to process that orderly aligned, size is suitable using duralumin, hard alumin ium alloy as matrix
When the special hole of shape is bumped into rolling bearing steel ball in its hole.Aperture uses newest groove circumference lock ball technique,
Solve the problems, such as that traditional type point type lock ball and impression lock ball cannot entirely prevent steel ball to fall off.Bottom hole processes 90 °
Seam allowance makes copper ball be freely rotated and not fall off in hole.Since the diameter of steel ball is greater than the wall thickness of retainer, so when in use
Steel ball is higher by the inside and outside circular surfaces of retainer, directly contacts with the hole of matching with axis, and matrix (retainer) is made to float on centre, and
The hole of matching and the difference of axis radius are less than steel ball size, i.e. steel ball is matched for interference fit, cooperation precision height, axis and hole phase
It is flexible to moving.It is to maintain the renewal product of frame.
Ball retainer is for engineering machinery, water conservancy machinery, metallurgical and mining machinery, electric machinery, medicinal mechanical, foods machine
Tool, agricultural machinery, aviation machine, textile machine, hydraulic machinery, automobile industry and printing packaging machinery, cold rolling industry etc..
Currently, the sleeve of ball retainer is made of copper, in use, ball retainer is set on cylindrical part,
Cylinder part is set on ball retainer again, but the mounting groove on the existing matrix of ball retainer uses linear array,
When needing cylinder part along the axial movement of itself, multiple steel balls form a line, and generate to the inner wall of cylinder part larger
Abrasion, be easy that part is made to be damaged.
Utility model content
Place in view of the deficiency of the prior art, the utility model, which is intended to provide one kind, prevents that steel ball is easy to fall off, subtracts
Small cylinder part abrasion, enhancing service life.
In order to solve the above technical problems, a kind of ball retainer provided by the utility model, including sleeve, and it is provided with set
Several mounting grooves on cylinder, and the steel ball being embedded on mounting groove, the line in the axle center of several mounting grooves helically line
Setting, the mounting groove are set as arc, each steel ball of sleeve surface it is vertical between be provided with oil pipeline.
Preferably, the diameter of the steel ball is 6-10mm.
Preferably, the sleeve is made of copper, aluminium or POM material.
Preferably, the surface of the sleeve is coated with a protective layer, and the protective layer is the guarantor of chlorinated rubber anti-corrosion material
Sheath.
Preferably, the outer dia of the sleeve is 4-90mm.
Preferably, the width of the oil pipeline is 0.05~0.1mm.
The utility model has the beneficial effects that passing through setting arc mounting groove, it is therefore prevented that steel ball is easy to fall off, sprays in sleeve surface
Be coated with a protective layer, improve the service life of the utility model, each steel ball of sleeve surface it is vertical between be provided with it is defeated
Oil-piping can be that steel ball lubrication is abundant, reduce the frictional force of steel ball and sleeve in lubricating oil spraying.
The detection data table of the utility model:
| Maximum load capacity | 120N/mm 2 |
| Assemble interference | 0.01mm-0.02mm |
| Highest sliding speed | 6M/s |
| Coefficient of friction | 0.01-0,08 |
| Steel ball size is inclined | <0.002mm |
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model sectional view；
Fig. 3 is the sectional view of the utility model top view.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
As shown in Figures 1 to 3, a kind of ball retainer of the utility model, including sleeve 1, and if being provided on sleeve 1
Dry mounting groove 2, and the steel ball 3 being embedded on mounting groove 2, helically line is arranged the line in the axle center of several mounting grooves 2,
The mounting groove 2 is set as arc, each steel ball 3 in 1 surface of sleeve it is vertical between be provided with oil pipeline 4.
The diameter of the steel ball 3 is 6-10mm.
The sleeve 1 is made of copper, aluminium or POM material.
The surface of the sleeve 1 is coated with a protective layer 5, and the protective layer 5 is the protective layer of chlorinated rubber anti-corrosion material
5。
The outer dia of the sleeve 1 is 4-90mm.
The width of the oil pipeline 4 is 0.05~0.1mm.
Lubricating oil is coated on specifically each steel ball 3 to generate when steel ball 3 rotates in mounting groove 2 to reduce
Frictional force, each steel ball 3 in 1 surface of sleeve it is vertical between be provided with oil pipeline 4, so that lubricating oil is quickly filled steel ball 3,
Can quickly reduce frictional force, improve the utility model service life, for the ease of manufacturing and improving toughness, steel ball 3 it is straight
Diameter is 6-10mm, and the outer diameter of sleeve 1 is 5-90mm, and sleeve 1 is made of copper, aluminium or POM material.
