Embodiment
Deep groove ball bearing retainer 100 according to embodiments of the present invention is described below with reference to Fig. 1~Fig. 4.Such as Fig. 1~Fig. 4
It is shown, the retainer 100 of deep groove ball bearing according to embodiments of the present invention, deep groove ball bearing include 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 100
On, retainer 100 includes：Retainer body, pocket hole 1 and annular groove 2.
Retainer body, retainer body is annular entity structure；Pocket hole 1, pocket hole 1 is uniformly located at retainer body
On, and rolling element is in pocket hole 1, that is to say, that pocket hole 1 is multiple, and is uniformly arranged along the periphery of retainer body,
Pocket hole 1 is corresponded with rolling element；Annular groove 2, annular groove 2 is provided with lubricating oil in pocket hole 1, and in annular groove 2, that is to say, that ring
Side wall of the shape groove along pocket hole 1 is set, and lubricating oil is provided with annular groove, effectively rolling element can be lubricated, reduction rolling
Abrasion of the kinetoplast to retainer 100, but also rolling element being produced because of friction between retainer 100 can be effectively absorbed
Raw heat.The retainer 100 is less likely to occur to damage, and extends the service life of retainer 100.
In one embodiment of the invention, as shown in Figure 1 to 4, in addition to guide hole 3, guide hole 3 is located at retainer body
Two side walls on, and extend to along the side wall perpendicular to retainer body, and be conducted with pocket hole 1.Specifically, guide hole 3
Corresponding with pocket hole 1, each guide hole 3 begins at the side wall of retainer 100, terminates in the inwall of annular groove 2, so can be constantly
Rolling element is given to provide lubricating oil, reducing worn and torn between rolling element and retainer 100 same makes, and can be absorbed with the flowing of lubricating oil
Frictional heat between rolling element and retainer 100.
In one embodiment of the invention, as shown in figure 4, also including oil groove 4, oil groove 4 is located at the side of retainer body
It is conducted on wall, and between oil groove 4 and annular groove 2 by guide hole 3.Specifically, oil groove 4 is annular groove, is arranged on the side of retainer
On wall, and the cell wall of oil groove 4 extends inside and outside.That is, the opening of oil groove 4 is small, the oily groove sidewall of retainer to its
Inside and outside extend, can so make retainer 100 when making revolution motion, lubricating oil can be stored in oil groove 4, contributed to
To the lubrication of rolling element.What deserves to be explained is, it is mentioned here it is inside and outside be relative position, i.e., the centre bit of close retainer 100
The side side wall put is inner side, and the side side wall away from the center of retainer 100 is referred to as outside.
Preferably, oil groove 4 and guide hole 3 are symmetrical arranged, as shown in Fig. 2 the both sides in each pocket hole 1 are equipped with guide hole 3, and are led
Hole 3 is connected with oil groove 4, so facilitates lubricating oil to enter in annular groove 2, and oil groove 4 and guide hole 3 are set into symmetrical structure can be with
Increase the quantity delivered of lubricating oil, strengthen lubricant effect；And with the increase of lubricants capacity, the lubricants capacity to flowing to rolling element
Also it can increase, so also contribute to uptake of the increase to heat between retainer 100 and rolling element.
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.
The deep groove ball bearing of embodiment includes above-mentioned retainer 100 according to a second aspect of the present invention.According to present invention implementation
The deep groove ball bearing of example, because the specific wearability of above-mentioned retainer 100 is strong, can self-lubricating, can effectively reduce friction temperature
