Along with the high speed development of clutch industry; demand to reverse clamping stopper bearing increases day by day; the current main dependence of reverse clamping stopper bearing assembling realizes by hand; labor intensity; manufacturing efficiency is low, production capacity is low, most importantly in assembling process, often there will be many dress elastic components or fills less the serious quality problems such as elastic component, causes bearing roller discontinuity; cause bearing stop reliability and running noise and dysfunction, finally affect use function and the life-span of clutch.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of Self-resetting reverse clamping stopper bearing, it is simple in structure, design ingenious, convenient and reliable assembly, meeting under the prerequisite of clamping stopper bearing expection stop performance and life requirements, can guarantee bearing function and stable performance simultaneously.
The technological scheme providing according to the utility model: the reverse clamping stopper bearing of Self-resetting, comprise outer ring, inner ring, retainer and rolling element, it is characterized in that: the inner circumferential surface of described outer ring is provided with the curvilinear plane of some groups of end-to-ends, described curvilinear plane one end is arcuate segment, the other end is straightway, and arcuate segment is connected with straightway rounding off; Described retainer is arranged between inner ring and outer ring, and rolling element is arranged in the installation fenestra of retainer; The installation fenestra place of described retainer has additional cantilever limiting stopper, and described cantilever limiting stopper one end is fixed on retainer, the cantilever limiting stopper the other end be provided with to rolling element one lateral buckling can elastic bending bending part.
As further improvement of the utility model, described cantilever limiting stopper is crotch shape, and itself and retainer are structure as a whole.
As further improvement of the utility model, described cantilever limiting stopper and retainer adopt polyether-ether-ketone resin, PA66 or PA46 material to be injected into integrative-structure.
As further improvement of the utility model, described retainer is provided with the locating mistake proofing groove for detection of mistakes and omissions phenomenon after rolling element assembling.
As further improvement of the utility model, between described inner ring and outer ring, be filled with lubricating grease.
compared with prior art, advantage is the utility model:the utility model is guaranteeing the relatively-stationary while of each component locations, by set up cantilever limiting stopper in the installation fenestra of retainer, cantilever limiting stopper has the function of elastic component, can solve the reset issues of reverse clamping stopper bearing rolling element in clutch process, make no longer elasticity of demand part of reverse clamping stopper bearing, thereby completely abolished installation elastic component operation, greatly improved the efficiency of assembling of product, reduced manufacture cost; And retainer added and be convenient to automatically assembling and mistake proofing design, can realize the automation assembling of reverse retaining assembly.

Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the reverse clamping stopper bearing of Self-resetting in embodiment is mainly comprised of parts such as outer ring 1, inner ring 2, retainer 3 and rolling elements 4, wherein, outer ring 1 is as stopping power bearing piece, inner ring 2 is as stopping power guide, rolling element 4 is as stopping power transmission part, retainer 3, for keeping each components position relatively fixing, is filled special impact-resistant abrasion-proof low-noise lubricating grease between inner ring 2 and outer ring 1.
As shown in Fig. 3 ~ Fig. 5, the inner circumferential surface of described outer ring 1 is provided with the curvilinear plane of some groups of end-to-ends, and described curvilinear plane one end is arcuate segment 9, and the other end is straightway 10, and arcuate segment 9 is connected with straightway 10 rounding ofves; Described retainer 3 is arranged between inner ring 2 and outer ring 1, and rolling element 4 is arranged in the installation fenestra 5 of retainer 3, and rolling element 4 forms reverse retaining assembly with retainer 3, refills and is fitted between outer ring 1, inner ring 2, realizes reverse locking function after assembling; Installation fenestra 5 places of described retainer 3 have additional cantilever limiting stopper 6, and described cantilever limiting stopper 6 one end are fixed on retainer 3, cantilever limiting stopper 6 the other ends be provided with to rolling element 4 one lateral bucklings can elastic bending bending part 6a.
