Abstract
The utility model discloses a bearing which comprises an inner ring and an outer rings. Sealing rings are arranged between two ends of the inner and the outer rings. The inner ring is composed of an upper inner ring and a lower inner ring. An upper and a lower cages are respectively arranged between the upper inner ring and the outer ring, and the lower inner ring and the outer ring. The upper and the lower cages are provided with a plurality of steel balls. The outer circles of the upper and the lower inner rings are respectively provided with arc-shaped channels matched with the steel balls. The arc-shaped channels matched with the steel balls are also arranged in the outer ring. The utility model has the advantages of easy processing and low cost, and is used for a transmission mechanism of washing machines.
Description
The utility model relates to a kind of bearing, is the bearing that is used on the washing machine transmission mechanism specifically.
At present, one of used bearing of washing machine transmission mechanism is single-row angular contact ball bearing.During this Bearing Installation, for making its axial load that can bear both direction, need with two cover bearings with back-to-back, install face-to-face, to constitute paired angular contact ball bearing.This single-row angular contact ball bearing is adding man-hour, must form a complete production network in pairs, and every pair of bearing must be same model, can not exchange during installation, and difficulty of processing is big, cost is high.
The purpose of this utility model is to provide a kind of easy processing, bearing that cost is low.
Above-mentioned purpose of the present utility model is realized by following technical solution:
This practical bearing comprises inner ring and outer ring, between the two ends of inside and outside circle seal ring is arranged, and its structural feature is that inner ring is made of last inner ring and following inner ring, between this upper and lower inner ring and the outer ring upper and lower retainer is arranged respectively, and some steel balls are housed on the upper and lower retainer.The arc raceway groove that cooperates with steel ball is arranged respectively on the cylindrical of upper and lower inner ring.The arc raceway groove that cooperates with steel ball is also arranged in the outer ring.
Because bearing outer ring of the present utility model is an integral body, inner ring is two, is about to two single-row angular contact ball bearings and makes a double-row angular contact bal bearing.Not only easily processing, cost is low, and can bear the bigger radial load and the axial load of either direction.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a bearing cross-sectional schematic of the present utility model.
Fig. 2 is the seal ring cross-sectional schematic among Fig. 1.
Fig. 3 is the retainer cross-sectional schematic among Fig. 1.
See Fig. 1, bearing of the present utility model comprises inner ring and outer ring 1.Wherein: inner ring is made of last inner ring 4 and following inner ring 7, all is processed with circumferential boss on the outer end cylindrical of this upper and lower inner ring, and the upper surface place of the lower surface place of the circumferential boss in last inner ring 4 outer ends and the circumferential boss in following inner ring 7 outer ends all is processed with the arc raceway groove; Be processed with groove half on the circle in the two ends of outer ring 1, to form step, two step places also circumferentially process an arc raceway groove along it, and this two arcs raceway groove is corresponding with two arc raceway grooves on upper and lower inner ring 4 and 7, and the radius of the two equates.
See Fig. 3, upper and lower retainer 5 and 6 is ring shape.The limit that all leans outward, the lower end of the upper end of holder 5 and following retainer 6, this two inclines and all is processed with 14 arc gap that are used to put steel ball on the limit, is separately installed with a steel ball 2 in each gap.During installation, the following retainer 6 that steel ball 2 will be housed earlier is enclosed within down on the inner ring 7, and the last outer ring 1 of cover, the following retainer 6 that has steel ball 2 is between following inner ring 7 and the outer ring 1, and steel ball 2 just in time places down in the arc raceway groove of inner ring 7 and outer ring 1.Wherein, the wrapping angle between steel ball 2 and arc raceway groove is 32 °.The holder 5 that will have steel ball 2 again is enclosed within on the inner ring 4, and with the two from the outer ring 1 the other end pack into simultaneously.At last, between the upper end and last inner ring 4 upper ends of outer ring 1, seal with seal ring 3 respectively between 1 lower end, outer ring and following inner ring 7 lower ends.See Fig. 2, be processed with two circumferential boss on the interior circle of seal ring 3,, play the effect of double-layer seal so that form lips.
Claims (2)
