Reference character: 1, outer ring; 2, inner ring; 3, positioning ring; 4, seal ring; 41, link; 5, oil hole; 6, locating slot; 7, fixed groove; 8, positioning part; 81, supporting section; 82, linkage section; 83, positioning section; 84, spacing section.
Embodiment
With reference to accompanying drawing, the utility model water pump bearing embodiment is described further.
A kind of bilateral three-layer sealed circle 4 bearing, comprise inner ring 2, outer ring 1 and ball, seal ring 4 and the positioning ring 3 for fixed seal ring 4 is provided with between inner ring 2 and outer ring 1, seal ring 4 is three layers, lubricating grease can be provided with between adjacent seals circle 4, the two ends of positioning ring 3 abut with inner ring 2 and outer ring 1 respectively, by the setting of three-layer sealed circle 4 and double-layer lubrication fat, dust and water is made more to be not easy to enter, even if more outer field lubricating grease receives pollution, also can be isolated by the lubricating grease of internal layer, the materials such as abundant guarantee dust or water can not enter Bearing inner, ensure that ball can rotate smoothly, also ensure that the working life of bearing, positioning ring 3 abuts with outer ring 1 and can tentatively prevent dust and water from entering simultaneously, between positioning ring 3 and seal ring 4, also can lubricating grease be set, the effect of water proof and dust proof can be ensured further, also certain locating effect can be played to inner ring 2, make inner ring 2 can stable rotation, be less likely to occur to rock, ensure that the using effect of bearing.
Link 41 is also provided with between inner ring 2 and outer ring 1, three-layer sealed circle 4 is connected by link 41, the cross section of link 41 is trapezoidal, the outside of link 41 abuts with positioning ring 3, by the setting of link 41, makes the seal ring 4 of three layers connection each other comparatively stable, ensure that the effect of sealing, fully contacting and mutually abutting simultaneously by link 41 and positioning ring 3, makes fixing more firm of seal ring 4 entirety, ensure that the effect of water proof and dust proof fully.
The surface with outer ring 1 is protruded in the outside of positioning ring 3, can directly by outside dust or water resistance gear and outer ring 1, by above setting, enough spaces can be provided for the setting that is fixing and seal ring 4 of retaining ring, ensure that positioning ring 3 is fixed fully, thus it is more firm to make seal ring 4 connect, and ensure that good sealing, and then ensure right dustproof and waterproof effect preferably.
The locating slot 6 for stationary positioned ring 3 is provided with inside outer ring 1, the sidewall slope of locating slot 6 arranges formation bearing surface, positioning ring 3 is formed with the positioning part 8 with locating slot 6 adaptation, when positioning part 8 is stressed, certain dispersion can be carried out to the power be subject to by inclined-plane, make positioning part 8 be not easy to damage, fix positioning ring 3 fully by locating slot 6 simultaneously.As preferably, positioning part 8 comprises the supporting section 81 abutted with locating slot 6 sidewall, the linkage section 82 abutted with bottom locating slot 6 and the positioning section 83 abutted with bearing surface, the various piece of positioning part 8 contacts with locating slot 6 fully, make positioning ring 3 obtain all directions and abut power fully, thus ensure the steadiness that positioning ring 3 is fixing, the length of supporting section 81 is less than the degree of depth of locating slot 6, above setting like this, supporting section 81 contacts completely with the sidewall of locating slot 6, power can be conducted to the sidewall of support slot by the face of whole contact when supporting section 81 is stressed, ensure that supporting section 81 is not easy bending or damages, thus ensure that retaining ring is connected firmly, thus ensure that the soundness that seal ring 4 connects.Further, the outside of locating slot 6 is communicated with auxiliary fixed groove 7, and positioning section 83 extends to flush with the end of outer ring 1 and forms spacing section 84 in fixed groove 7, by spacing section 84 with the coordinating of fixed groove 7, positioning ring 3 can be fixed fully further, ensure sealing effect.
