Embodiment
Deep groove ball bearing retainer 100 below with reference to Fig. 1~Fig. 4 descriptions according to the utility model embodiment.As Fig. 1~
Shown in Fig. 4, according to the retainer 100 of the deep groove ball bearing of the utility model embodiment, deep groove ball bearing includes bearing inner race, axle
Bearing outer-ring, rolling element and retainer 100, for retainer 100 between bearing inner race and bearing outer ring, rolling element is installed on holding
On frame 100, retainer 100 includes：Retainer body, pocket hole 1 and annular groove 2.
Retainer body, retainer body are annular entity structure；Pocket hole 1, pocket hole 1 is uniformly located at retainer body
On, and rolling element is arranged 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 corresponds with rolling element；Annular groove 2, annular groove 2 are provided with lubricating oil in pocket hole 1 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, and reduces 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 present utility model, as shown in Figure 1 to 4, in addition to guide hole 3, guide hole 3 are located at retainer
In two side walls of body, and extend to along the side wall perpendicular to retainer body, and be conducted with pocket hole 1.Specifically, lead
Hole 3 is corresponding with pocket hole 1, and each guide hole 3 begins at the side wall of retainer 100, terminates in the inwall of annular groove 2, so may not be used
Disconnected ground gives rolling element to provide lubricating oil, and reducing worn between rolling element and retainer 100 same makes, with the flowing meeting of lubricating oil
Absorb frictional heat between rolling element and retainer 100.
In one embodiment of the present utility model, as shown in figure 4, also including oil groove 4, oil groove 4 is located at retainer body
Side wall on, and be conducted between oil groove 4 and annular groove 2 by guide hole 3.Specifically, oil groove 4 is annular groove, is arranged on retainer
Side wall on, and the cell wall of oil groove 4 extends inside and outside.That is, the opening of oil groove 4 is small, the oil groove side wall of retainer
Extend inside and outside to it, can so making retainer 100, lubricating oil can be stored in oil groove 4, had when making revolution motion
Help the lubrication to rolling element.What deserves to be explained is it is relative position inside and outside mentioned here, i.e., in retainer 100
The side side wall of heart position 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
