Abstract
The utility model discloses a structurally improved bearing for agricultural machinery. The structurally improved bearing for the agricultural machinery comprises an outer bearing ring, an inner bearing ring and rolling elements evenly distributed between the inner bearing ring and the outer bearing ring. A shaft hole of the inner bearing ring is in the shape of a cuboid, and oil grooves are arranged in four side walls of the shaft hole. Due to the fact that the oil grooves are arranged on the four side walls of the shaft hole, the structurally improved bearing for the agricultural machinery reduces the friction surface between a shaft and the shaft hole, at the same time, reduces the frictional factor and effectively reduces noise in operation.
Description
Technical field
The utility model relates to a kind of bearing, is meant a kind of novel bearing that is applicable to agricultural machinery especially.
Background technique
Bearing (" Bearing ", Japan's person " axle receives ") is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into two types on rolling bearing and sliding bearing.
Bearing generally include bearing outer ring, bearing inner race and be uniformly distributed in bearing inner race and bearing outer ring between rolling element.There is the big and not good defective of lubrication effect of noise in use usually in existing bearing.
The model utility content
The bearing that the utility model provides a kind of agricultural machinery to use, its purpose are to overcome the above-mentioned defective that existing technology exists.
The technological scheme of the utility model is following:
A kind of agricultural machinery of architecture advances is used bearing, comprise bearing outer ring, bearing inner race and be uniformly distributed in bearing inner race and bearing outer ring between rolling element, the axis hole of said bearing inner race is cuboid shape, all offers oil groove on four sidewalls of axis hole.
As the improvement of the utility model, for the ease of oil-feed, said oil groove is curved.
As the further improvement of the utility model, the length and the width of said axis hole are 50mm-70mm.The aperture of axis hole is comparatively suitable between 50mm to 70mm, and it can effectively hold out against axle.
As the further improvement of the utility model, four bights of said axis hole are circular arc.
Can know that by above-mentioned description compare with existing technology, the advantage of the utility model is to the utility model:
1, axis hole is square, and it can closely cooperate with square axle, can not only effectively reduce mechanical failure, and can greatly prolong the working life of bearing.
2, all offer oil groove on axis hole four sidewalls, reduced the rubbing surface between axle and the axis hole, reduced friction factor simultaneously, noise when effectively reducing work.
Description of drawings
Fig. 1 is embodiment one a structural representation.
Fig. 2 is embodiment two a plan view.
Embodiment
The embodiment of the utility model is described with reference to the accompanying drawings.
Embodiment one
With reference to Fig. 1; A kind of agricultural machinery of architecture advances is used bearing; Comprise bearing outer ring 1, bearing inner race 2 and be uniformly distributed in bearing inner race 2 and the rolling element (not drawing among the figure) of 1 of bearing outer ring; The axis hole 3 of said bearing inner race 2 is cuboid shape, and four bights 4 of this axis hole 3 are circular arc, all offer the oil groove 5 of arc on four sidewalls of axis hole 3.
The length and the width of axis hole 3 are 70mm, and axis hole 3 is the square bodily form, and it can closely cooperate with square axle (not drawing among the figure), can avoid problem of slip to take place fully, thereby reduce mechanical failure, and greatly prolong the working life of bearing.
Embodiment two
With reference to Fig. 2; A kind of agricultural machinery of architecture advances is used bearing; Comprise bearing outer ring 1 ', bearing inner race 2 ' and be uniformly distributed in bearing inner race 2 ' and bearing outer ring 1 ' between rolling element (not drawing among the figure); The axis hole 3 ' of said bearing inner race 2 ' is cuboid shape, and four bights 4 ' of this axis hole 3 ' are circular arc.All offer the oil groove 5 ' of arc on four sidewalls of axis hole 3 ', the upper end of each oil groove 5 ' is equipped with the pasta 6 ' of taper.
The length and the width of axis hole 3 ' are 50mm, and axis hole 3 ' is the square bodily form, and it can closely cooperate with square axle (not drawing among the figure), can avoid problem of slip to take place fully, thereby reduce mechanical failure, and greatly prolong the working life of bearing.
The above-mentioned embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
