Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, monolithic devices four point cantact seal ball bearing detailed description of the invention, structure, feature and the effect thereof for vehicle electric power-assisted steering device that the utility model proposes foundation, after describing in detail such as.
See Fig. 1 to Fig. 6, monolithic devices four point cantact seal ball bearing for vehicle electric power-assisted steering device of the present utility model, including outer ring 1, inner ring 2, steel ball 3, retainer 4, steel ball 3 is placed on outer ring 1 on circular arc road A8 and inner ring 2 in the raceway 10 of circular arc road B9 composition, steel ball 3 is outside equipped with retainer 4, wherein: sealing ring 6 is placed in the seal groove 7 between outer ring 1 and inner ring 2.Raceway 10 is peach-shaped raceway.Being provided with the end-play less than 30 μm between steel ball 3 and outer ring 1, inner ring 2, nominal contact angle α is 25 °-30 °.Raceway 10 radius Re (Ri) is 0.51-0.53 with the ratio of steel ball 3 diameter Dw.Equipped with rivet 5 on retainer 4.Outer ring 1 and sealing ring 6 use axial contact to seal.Inner ring 2 uses small-gap suture to coordinate with sealing ring 6.Sealing ring 6 is rubber seal.
During use, on outer ring 1, circular arc road A8 forms peach-shaped raceway with circular arc road B9 on inner ring 2, and when no-load or purely radial load effect, steel ball 3 and outer ring 1, inner ring 2 are in four point cantact；When the most purely axial load effect, steel ball 3 and outer ring 1, inner ring 2, in two-point contact, can bear two-way axial load, had single-row angular contact ball bearing and double-row angular contact bal bearing feature concurrently.In the case of the appearance and size not changing bearing and mounting means, improve axial load ability, and be provided with the axial limiting ability of good both direction.The utility model simple in construction, high reliable, the economy and durability, easy to maintenance of carrying, be suitable for promoting the use of of vehicle electric power-assisted steering device bearing.
