Description
Technical field
The utility model relates to bearing retainers, relate generally to a kind of deep groove ball bearing low friction nylon cages.
Background technique
Deep groove ball bearing has the features such as widely used, production is of large quantities, and bearing designation is more, and wherein nylon cages have
It is light-weight.Self-lubricating is good, impact resistance, it is at low cost the advantages that, nylon cages are widely used in deep groove ball bearing.With the hair of industry
Exhibition, more stringent requirements are proposed for the antifriction performance of " energy-saving " to deep groove ball bearing, and traditional deep groove ball bearing can not
Meet working condition requirement, the research and development of low energy consumption deep groove ball bearing are imperative.
Summary of the invention
In order to solve the above technical problems, the purpose of this utility model is to propose that a kind of deep groove ball bearing low friction nylon is kept
Frame.
Following technical solution can be used to realize in the purpose of this utility model:
A kind of deep groove ball bearing low friction nylon cages, the frame body of retainer are annular shape；There is edge on the frame body
Multiple pocket holes to install steel ball of circumference uniform distribution, and multiple pocket holes are located on the side wall surface of frame body；Described
The spherical shape of pocket Kong Weiyi side opening；The wall thickness of the frame body is 0.28-0.32 times of steel ball steel ball size；Outside the frame body
There are the multiple boss being uniformly distributed along the circumference on diametric plane；Multiple boss and multiple pocket holes correspond；Each institute
The boss stated is located at the outside in corresponding pocket hole；Through-hole is all had on each pocket hole, and the through-hole is symmetrically to set
Two set；The interior lock claw and external lock to prevent steel ball from dropping out from pocket hole are provided on the side wall surface of pocket hole open end
Pawl；Annular groove is provided between the interior lock claw and outer lock claw；There is annular through groove in another side wall surface of the frame body, and
The annular through groove is connected with two through-holes on each pocket hole, forms the through hole for facilitating retainer lubrication heat dissipation.
The through-hole is square through hole or circular through hole or ellipse hole.
The utility model proposes a kind of deep groove ball bearing low friction nylon cages, retainer have relatively thin radial wall
It is thick that (common retainer wall thickness is 0.45---0.48 times of steel ball size, this kind of novel low friction retainer wall thickness is steel ball size
0.28-0.32 times), the setting of through-hole can be such that the contact surface of steel ball and retainer reduces on wall thickness reduction and pocket hole, increase
Lubricating oil circulation improves the greasy property between retainer and steel ball, reduces friction；Pocket hole bottom outer diameter face designs for boss,
To enhance pocket hole bottom strength and not influence lubricating oil circulation；There is annular groove between outer lock claw and interior lock claw, reduces friction and increase
Lubrication, the design of through hole reduce friction, increase lubricating oil circulation；In conclusion retainer described in the utility model
The characteristics of small with frictional force, lubrication is sufficiently, light-weight, saves material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the B-B cross-sectional view of Fig. 1.
Fig. 3 is the A-A cross-sectional view of Fig. 1.

Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments:
As shown in Figure 1 and Figure 2, a kind of deep groove ball bearing low friction nylon cages, the frame body 1 of retainer are annular shape；Institute
The wall thickness for stating frame body is 0.28-0.32 times of steel ball steel ball size；On the frame body 1 have be uniformly distributed along the circumference it is multiple to
The pocket hole 2 of steel ball is installed, and multiple pocket holes 2 are located on the side wall surface of frame body 1；The pocket hole 2 is a side opening
Spherical shape；There are the multiple boss 3 being uniformly distributed along the circumference in the outer diameter face of the frame body 1；Multiple boss
3 correspond with multiple pocket holes 2；Each boss 3 is located at the outside in corresponding pocket hole 2；In conjunction with
Fig. 3 each all has through-hole 5 on the pocket hole 2, and the through-hole 5 is symmetrically arranged two；The pocket hole 2 is open
The interior lock claw 6 and outer lock claw 7 to prevent steel ball from dropping out from pocket hole are provided on the side wall surface at end；6 He of interior lock claw
Annular groove is provided between outer lock claw 7；There is annular through groove 4, and the annular through groove in another side wall surface of the frame body 1
4 are connected with two through-holes 5 on each pocket hole, form the through hole for facilitating retainer lubrication heat dissipation.
The through-hole is square through hole or circular through hole or ellipse hole.
