Abstract
The invention provides a bearing bush. The bearing bush comprises a semi-cylindrical bearing bush body, and oil storage points are distributed in the inner wall of the bearing bush body. In addition, the bearing bush body is 298-312 mm in length, 220-235 mm in inner diameter and 16-20 mm in wall thickness. The oil storage points of the bearing bush are used for storing lubrication oil, so that the lubrication level is improved, the friction between the bearing bush and a rotary shaft is reduced, and the inner wall of the bearing bush and the outer wall of the rotary shaft are prevented from scuffing and pulling damage; the rotary shaft and the bearing bush are protected, and the service life of the rotary shaft and the bearing bush is prolonged.
Description
Technical field
The present invention relates to a kind of bearing shell, particularly relate to a kind of reduction friction factor, prevent between axle and bearing shell because of the bearing shell causing pulling that rubs.
Background technique
Bearing shell is that rotating shaft is held and be coupling tactile part.When turning bearing working, bearing shell and rotating shaft direct friction, easily pull bearing shell and rotating shaft, and friction simultaneously can produce very high temperature, easily causes the damage of axle, reduces its working life.
Therefore, require one deck oil film between bearing shell and rotating shaft to shield.Traditional bearing shell inwall is smooth design, cannot store after lubricant oil enters bearing shell inwall, therefore need frequently to add lubricant oil, and whole topping-up operation is comparatively loaded down with trivial details, operation inconvenience.
Summary of the invention
The object of the present invention is to provide one can oil storage, to reduce friction factor, prevent between axle and bearing shell because friction causes the bearing shell pulled.
Bearing shell provided by the invention, comprises semi-circular cylindrical bearing shell body, it is characterized in that, bearing shell inner body wall is distributed with oil storage point.
In some embodiments, be provided with several oil storage points, oil storage point is uniformly distributed in bearing shell inner body wall.
In some embodiments, bearing shell body two ends are provided with spacing flange, and often hold spacing flange two side plane to be respectively equipped with a mounting hole, mounting hole is perpendicular to plane.
Bearing shell provided by the invention, its oil storage point, for storing lubricant oil, improves lubricity, reduces the friction between bearing shell and rotating shaft, prevents bearing shell inwall and rotating shaft outer wall plucking, pulls, and protection rotating shaft and bearing shell improve the working life of rotating shaft and bearing shell.
Accompanying drawing explanation
Fig. 1 is the structural representation of the bearing shell of one embodiment of the present invention.
Embodiment
Explanation that the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 1 show schematically show the bearing shell according to one embodiment of the present invention.
As shown in Figure 1, bearing shell provided by the invention, comprises semi-circular cylindrical bearing shell body 1.
Wherein, the length of bearing shell body 1 is 298mm-312mm, and internal diameter is 220mm-235mm, and wall thickness is 16mm-20mm, and in this mode of execution of the present invention, the length of bearing shell body 1 is adopted as 300mm, and internal diameter is 220mm, and wall thickness is 19mm.
As shown in the figure, bearing shell body 1 two ends are provided with spacing flange 101, and the thickness of spacing flange 101 is 12mm-20mm, and in this mode of execution of the present invention, the thickness of spacing flange 101 adopts 17mm.Often hold spacing flange 101 liang of side planes 1011 to be respectively equipped with a mounting hole 1012, mounting hole 1012 is perpendicular to plane 1011.Spacing flange 101 for fixing bearing shell body 1, to bearing shell body 1 position-limiting action.
In addition, bearing shell body 1 inwall is evenly distributed with oil storage point 11.In this mode of execution of the present invention, as shown in the figure, bearing shell body 1 inwall is evenly distributed with 6 row's oil storage points 11, and often row is provided with 4, and the distance of often arranging between adjacent two oil storage points is 35mm.As shown in the figure, oil storage point 11 semicircular in shape, its length is 9.05mm-12mm, and width is 5mm-7mm, and oil storage point 11 is circular arc at bearing shell body 1 radial cross section, and the degree of depth of oil storage point 11 is 0.4mm-0.5mm.In this mode of execution of the present invention, the length of oil storage point 11 is set to 11mm, and width is set to 6mm, and radius of the radian is set to 0.4mm.
In sum, bearing shell provided by the invention, its oil storage point, for storing lubricant oil, improves lubricity, reduces the friction between bearing shell and rotating shaft, prevents bearing shell inwall and rotating shaft outer wall plucking, pulls, and protection rotating shaft and bearing shell improve the working life of rotating shaft and bearing shell.
