Description
Technical field
The present invention relates to technical field of bearings, more particularly to a kind of rolling bearing retainer.
Background technology
Retainer is the important component in rolling bearing, for wrapping up rolling element, with separation roller.Because bearing is in work
During work, phase mutual friction between rolling element and retainer produces substantial amounts of heat；In the prior art, to the lubrication side of bearing
Formula is generally the modes such as drip lubrication, circulating oil lubrication, because these lubricating system lubricating oil can not fast and effectively go directly rolling
At body, lubricant effect is caused and bad, the retainer of such rolling bearing can be worn and torn by rolling element, easily be damaged,
So as to reduce the service life of retainer.
The content of the invention
In view of the above-mentioned problems of the prior art, it is an object of the invention to propose a kind of rolling bearing retainer, should
Retainer high lubricating effect, can reduce the temperature of rolling element, it is not easy to be damaged, and extend the service life of retainer.
To achieve these goals, the present invention provides a kind of rolling bearing retainer, and the rolling bearing is included in bearing
Circle, bearing outer ring, rolling element and retainer, the retainer are located between the bearing inner race and the bearing outer ring, described
Rolling element is installed on the retainer, it is characterised in that the retainer includes：Retainer body；Pocket hole, the pocket hole is equal
It is even to be located at the upper of the retainer body, and the rolling element is in the pocket hole；Passage, the passage is located at two phases
Between the adjacent pocket hole, and connect adjacent pocket hole.
, can be effectively by setting passage between the two neighboring pocket hole of retainer body in the technical scheme
Rolling element is lubricated, abrasion of the reduction rolling element to retainer, but also can effectively absorb rolling element with holding
The heat produced by friction between frame.The retainer is less likely to occur to damage, and extends the service life of retainer.
In addition, according to a kind of rolling bearing retainer of the present invention, can also have following technical characteristic：
Further, in addition to connecting hole, the connecting hole is located at two adjacent pocket bore regions of retainer body
Side wall is set, and it connects with the passage.
Further, the connecting hole is through to its opposite side by the side of described this body sidewall of retainer.
Further, the connecting hole is multiple, and along the circumferentially disposed of the retainer body.
Preferably, the passage generally circular configuration.
Alternatively, the pocket hole is cylindrical hole, spherical pore or bellmouth.
Preferably, the rolling bearing retainer is formed in one part.
Preferably, the rolling bearing retainer is made up of polyether-ether-ketone.

Embodiment
Below with reference to rolling bearing retainer 100 according to embodiments of the present invention is described in detail as shown in Figure 1 to 4.Such as
Shown in Fig. 1~Fig. 4, the retainer 100 of rolling bearing according to embodiments of the present invention, rolling bearing includes bearing inner race, bearing
Outer ring, rolling element and retainer 100, retainer 100 are located between bearing inner race and bearing outer ring, and rolling element is installed on retainer
On 100, retainer 100 includes：Retainer body, pocket hole 1 and passage 2.
Retainer body, retainer body pocket hole 1, pocket hole 1 is uniformly located at the upper of retainer body, and rolling element is arranged on
In pocket hole 1, that is to say, that pocket hole 1 is multiple, and is uniformly arranged along the periphery of retainer body, and pocket hole 1 and rolling element are one by one
Correspondence；Passage 2, passage 2 is located between two adjacent pocket holes 1, and connects adjacent pocket hole 1, that is to say, that passage 2 is located at two
Between the adjacent region of pocket hole 1, two pocket holes 1 are connected, such lubricating oil can flow inside retainer 100, make profit
Sliding effect more preferably, reduces abrasion of the rolling element to retainer；Moreover, as the flowing of lubricating oil can absorb rolling element and holding
Rub the heat of generation between frame 100.The retainer 100 is less likely to occur to damage, and extends the service life of retainer 100.
In some embodiments of the invention, in addition to connecting hole 3, connecting hole 3 be located at two of retainer body it is adjacent
The side wall in the region of pocket hole 1 set, can so reduce the damage to retainer bulk strength；And connecting hole 3 is mutually passed through with passage 2
Logical, such lubricating oil can be by the flow channel 2 of connecting hole 3, and increases lubricating oil mobility and flow on retainer 100, from
And lubricant effect is further enhanced, strengthen absorption of the lubricating oil to frictional heat between rolling element and retainer 100.
In some embodiments of the invention, connecting hole 3 is through to its opposite side by the side of retainer this body sidewall,
That is, connecting hole 3 is through hole and to be connected with passage 2, such lubricating oil can by retainer body both sides side wall simultaneously
Into in retainer 100, the mobility and flow of lubricating oil can be strengthened, so as to strengthen lubricant effect.
In one embodiment of the invention, connecting hole 3 is multiple, and along the circumferentially disposed of retainer body, is set
Multiple connecting holes 3 can further strengthen the mobility and flow of lubricating oil, so as to can effectively be inhaled while strengthening lubricant effect
Receive the heat produced between retainer 100 and rolling element by friction.
Preferably, the generally circular configuration of passage 2, with simplified processing process, can so improve the production effect of retainer 100
Rate, so as to reduce production cost.
Alternatively, as shown in figure 3, pocket hole 1 can be cylindrical hole, spherical pore or bellmouth, the shape of pocket hole 1 is not limited
Annular groove 2 can be formed in system, these pocket holes 1.
Preferably, deep groove ball bearing retainer 100 is formed in one part.For example, deep groove ball bearing retainer 100 is in production
It can be integrally formed in manufacturing process by the form for forging and pressing or casting, can so improve the structural strength of retainer 100, and
And the trouble of assembling is avoided, improve the manufacturing efficiency of bearing.
Preferably, deep groove ball bearing retainer 100 is made up of polyether-ether-ketone.Polyether-ether-ketone has good toughness and firm
Property, and its excellent endurance to alternate stress is most outstanding in all plastics, so retainer 100 can be made to adapt to depth
The environment of the alternate stress of ditch ball bearing, so as to improve the service life of retainer 100.What deserves to be explained is, polyether-ether-ketone exists
Bear that there is self-lubricating property during certain high temperature, so can make bearing in high temperature environments, rolling element and retainer 100 it
Between form self-lubricating film, with the rotation of bearing, self-lubricating film is transferred on raceway, reduces raceway and rolling element
Between abrasion, extend bearing life-span.
