Abstract
The utility model discloses an irregularly-shaped turntable bearing for sewage treatment. The turntable bearing comprises an outer ring, an inner ring and steel balls arranged between the inner and outer rings, wherein the outer ring is provided with an internal space communicated with the outside; a partition plate is arranged in the internal space; the partition plate and the sidewall of the internal space form a rolling body space for the steel balls; wear-proof steel rings are correspondingly embedded into the upper and lower parts of the rolling body space; the steel balls roll on the wear-proof steel rings; the inner ring is provided with an extending part which extends into the internal space of the outer ring and seals the rolling body space. The turntable bearing is assembled after being cast from a cast steel material, and is convenient to machine, the utilization rate of the material is increased, and the cost is lowered; in addition, a roller path of the steel balls is formed by the wear-proof steel rings, so that the wear resistance of the roller path is improved, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to the turntable bearing of mechanical field, specifically the special-shaped turntable bearing of a kind of sewage treatment.
Background technique
The turntable bearing that in prior art, sewage treatment is used, owing to considering the particularity of sewage treatment, generally all adopt special-shaped turntable bearing, these special-shaped turntable bearings are stressed little, but textural anomaly complexity, the general method of forging that adopts is manufactured each parts and then assembling, but has the problems such as stock utilization is low, cost is high, processing difficulties.And after forging molding, the intensity of raceway is very low, cause the working life of special-shaped turntable bearing very low, can not well satisfy the demand.
Model utility content
For solving in prior art low problem of special-shaped turntable bearing processing difficulties for sewage treatment, working life, the utility model provides a kind of sewage treatment special-shaped turntable bearing, after adopting cast steel material casting, each parts of this turntable bearing assemble, improve the utilization ratio of material, not only be convenient to processing, and reduced cost; Meanwhile, by being set, improved by wear-resisting steel ring the working life of bearing.
The utility model is that the technological scheme that solves the problems of the technologies described above employing is: the special-shaped turntable bearing of a kind of sewage treatment, comprise outer ring, inner ring and be arranged on the steel ball between Internal and external cycle, described outer ring has a built-in space being in communication with the outside, in this built-in space, be provided with dividing plate, the sidewall in dividing plate and built-in space forms the rolling element space of steel ball, the upper and lower correspondence in rolling element space is inlaid with wear-resisting steel ring, steel ball rolls on wear-resisting steel ring, described inner ring has an extension part, this extension part stretches in the built-in space of outer ring and by rolling element space sealing.
The sidewall in described extension part and dividing plate, built-in space is construed as limiting the position-limit mechanism of steel ball sideslip.
Described dividing plate one end is fixed on the top, built-in space of outer ring, the other end is to have the domatic free end of an arc, arc sidewall domatic and built-in space forms the rolling element space of steel ball, extension part and dividing plate fit tightly, and the end of extension part is connected with the built-in space of outer ring by sealing plug, thereby realize the sealing to rolling element space.
Described outer ring, inner ring, dividing plate and extension part all adopt cast steel material casting.
Beneficial effect: the utility model assembles after adopting cast steel material casting, has improved the utilization ratio of material, is not only convenient to processing, and has reduced cost; Meanwhile, form the rolling raceway of steel ball by wear-resisting steel ring is set, improved like this wear resistance of raceway, thereby improved the working life of bearing.
