Abstract
The utility model discloses a bearing for farm machinery. The bearing for the farm machinery comprises a bearing outer ring, a bearing inner ring and rolling bodies, and the rolling bodies are evenly distributed between the bearing inner ring and the bearing outer ring. A shaft hole of the bearing inner ring is in a rectangular shape, and four corners of the shaft hole are in a circular arc shape. The shaft hole is in a square shape and can be closely matched with a square shaft so that occurrences of slipping can be completely avoided and mechanical failures are decreased, and service life of the bearing is greatly prolonged.
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; Axle is installed in the bearing inner race during use; Reality can run into such problem when using usually, because the axis hole of existing bearing inner race all is rounded, axle is easy to skid when in axis hole, moving; This will cause mechanical failure, and influences working life.
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:
Agricultural machinery 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, four bights of this axis hole are circular arc.The bight of circular arc is convenient to square shaft extension and is gone in the axis hole.
As the 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.
Can know that by above-mentioned description compare with existing technology, the advantage of the utility model is: axis hole is square to the utility model; It can closely cooperate with square axle; Can avoid problem of slip to take place fully, thereby reduce mechanical failure, and greatly prolong the working life of bearing.
Description of drawings
Fig. 1 is embodiment one a structural representation.
Fig. 2 is embodiment two a plan view.
Fig. 3 is embodiment three 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; Agricultural machinery 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 21 of said bearing inner race 2 is cuboid shape, and four bights 22 of this axis hole 21 are circular arc.
The length and the width of axis hole 21 are 70mm, and axis hole 21 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; Agricultural machinery 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 21 ' of said bearing inner race 2 ' is cuboid shape, four bights 22 ' of this axis hole 21 ' are circular arc.
The length of axis hole 21 ' is 70mm; Width is 50mm, and axis hole 21 ' is cuboid shape, 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 three
With reference to Fig. 3; Agricultural machinery is used bearing; Comprise bearing outer ring 1 ' ', bearing inner race 2 ' ' and the rolling element (not drawing among the figure) that is uniformly distributed in bearing inner race 2 ' between ' and bearing outer ring 1 ' '; Said bearing inner race 2 ' ' axis hole 21 ' ' is cuboid shape, this axis hole 21 ' ' four bights 22 ' ' is circular arc.
Axis hole 21 ' ' length and width be 50mm; Axis hole 21 ' ' be the square bodily form, it can closely cooperate with square axle (not drawing among the figure), can avoid problem of slip to take place fully; Thereby reduced mechanical failure, and greatly prolonged 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.
Claims (2)
1. agricultural machinery 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, it is characterized in that: the axis hole of said bearing inner race is cuboid shape, four bights of this axis hole are circular arc.
