Abstract
The utility model discloses a steering knuckle bearing which is characterized by comprising a shaft washer, a holder and a race, wherein the shaft washer, the holder and the race are sequentially installed in a housing from top to bottom. A steel ball is arranged between the shaft washer and the race in a clamped mode and located in the holder. A step is arranged on the junction position of the lower portion of the outer periphery of the race and the plane. A seal ring is installed on the step of the race and made of rubber. The seal ring is positioned by the inner flanging of a housing mouth. The steering knuckle bearing has the advantages of being simple in structure, convenient to use, reliable and safe. The problems that the seal ring is prone to being deformed when the housing and the seal ring are sealed in a rolled mode, and a bearing inflexibly rotates after sealed are solved. The problem that the housing is difficult to seal is solved as well.
Description
Technical field
The utility model belongs to bearing, relates to a kind of free bearing.
Background technique
Free bearing is along with the development of bearing industry, very large variation has occured in the structure of free bearing, entirely wrap in the case external diameter that the second type case only encases bearing shaft, seat ring from axle, the seat ring of bearing, the failure mode of bearing, failure rate are reduced greatly.Progress along with society, expanding economy, automobile industry and user vehicle increase day by day to the free bearing demand of long lifetime, good airproof performance, but the structure that only is the case external diameter that encases bearing shaft, seat ring can not satisfy the demands, so develop a kind of inside and outside free bearing with seal ring, the sealability of bearing is improved, but for bearing manufactory, this bearing pack with seal ring is equipped with certain difficulty, easily causes bearing rotary dumb.
Summary of the invention
The utility model provides a kind of free bearing simple in structure, esy to use, safe and reliable in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Free bearing of the present utility model, it is characterized in that: comprise the blowout patche, retainer and the seat ring that are installed in successively from top to bottom in the case, steel ball is clipped between blowout patche and the seat ring and is positioned at retainer, there is a step at seat ring excircle bottom and plane convergence place, seal ring is installed on the step of seat ring, seal ring is made by rubber, and seal ring is by the in-flanges location of case mouth.
Preferred version is, described case mouth contacts part with seal ring, and the step of an indent is arranged on the case, attenuate the thickness of case.1.7 millimeters of the step degree of depth of case, 0.4 millimeter of width.
The beneficial effects of the utility model are, and are simple in structure, esy to use, safe and reliable, solved seal ring inflexible problem of rotation after the roll extrusion sealing easily produces distortion, bearing sealing, also solved the large problem of case sealing difficulty.
Description of drawings
Fig. 1 is that shaft section of the present utility model partly cuts open schematic diagram.Fig. 2 is that the shaft section of case before seal ring is installed partly cuts open schematic diagram.
Among the figure, 01 seat ring, 02 blowout patche, 04 steel ball, 07 retainer, 08 circular seal ring, 68 seal rings, 93 cases, 09 step.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Free bearing of the present utility model, comprise the blowout patche 02, retainer 07 and the seat ring 01 that are installed in successively from top to bottom in the case, steel ball 04 is clipped between blowout patche and the seat ring and is positioned at retainer, there is a step at seat ring excircle bottom and plane convergence place, seal ring 68 is installed on the step of seat ring, seal ring is made by rubber, and seal ring 68 is by the in-flanges location of case mouth.Blowout patche 02 is by case 93 upper bottom surfaces location, and seat ring 01 is equipped with circular seal ring 08 by the seal ring location between blowout patche 02 inner circumference top and the case upper bottom surface.Described case mouth contacts part with seal ring, and the step 09 of an indent is arranged on the case, attenuate the thickness of case.Described before seal ring is installed, 1.7 millimeters of the step degree of depth of case, 0.4 millimeter of width.
Among Fig. 1, seat ring 01 outer radius has a step, and seal ring 68 is placed on the step of seat ring 01, and seat ring 01 links together seal ring 68 with case 93 after compressing with seal ring 68 again, and a whole set of bearing is integrated.Because seal ring 68 is rubber material, certain elasticity is arranged, when case 93 seals with seal ring 68, seal ring is deformed, cause bearing rotary dumb.
Among Fig. 2, the position that case 93 lower ends contact with seal ring 68, made a degree of depth 1.7 on the case, the step 09 of width 0.4, attenuate the thickness of case, when making case 93 and seal ring 68 be connected sealing by pressure, case easily stretches, and attenuate place 45 degree that curve inwardly are connected as one with seal ring.Like this, both solve the inflexible problem of bearing rotary, also solved the large problem of case sealing difficulty.
