In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view at the I place of Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the standard Contact Seal ring with shoulder protector providing in figure and the composite structure of standard Contact Seal ring, comprise the seal ring 500 that is arranged between bearing outer ring 100 and bearing inner race 200 and the corresponding seal ring 500a with seal ring 500, seal ring 500 contacts with bearing support, between bearing outer ring 100 and bearing inner race 200, be also provided with retainer 300, each the ball pocket 310 on retainer 300 is provided with a ball 400.
Seal ring 500 comprises skeleton 510 and is coated on skeleton 510 seal 520 around, seal ring 500a comprises skeleton 510a and is coated on skeleton 510a seal 520a around, skeleton 510,510a are " L " type skeleton that adopts low carbon steel plate material to make, this skeleton is lightweight, softness and hardness moderate, be mainly used in supporting seal 520,520a.Seal 520,520a adopt some non-metallic elastic materials such as rubber to make, not only durable, elasticity foot, and also cost is lower, effectively reduces production costs.
Referring to Fig. 2, seal 520 comprises sealed outer ring portion 521 and sealing inner ring portion 522, the head 521a of sealed outer ring portion 521 coordinates with the dustproof groove 110 of bearing outer ring 100, and the back of sealed outer ring portion 521 is provided with one and stretches out and the shoulder protector 521b parallel with the end face of bearing inner race 200.Because bearing can produce heat in operation process; shell is that the bearing saddle bore of aluminum or aluminum alloy is due to expanded by heating; cause aperture to become large; easily make bearing outer ring 100 produce abnormal slip; unstable wear; but have seal ring 520 to be firmly arranged between bearing outer ring 100 and bearing inner race 200, shoulder protector 521b has increased the frictional force with bearing saddle bore inwall, has stoped the abnormal slip of bearing outer ring 100.
