Abstract
The utility model discloses a slewing bearing spacer, which comprises a spacer body. Two end faces of the spacer body are concave spherical faces, the outer circumference face of the spacer body is a uniparted hyperboloid, a first oil storage pit is arranged at the center of each concave spherical face, third oil storage pits are uniformly and alternately arranged on a portion, close to the edge, of each concave spherical face along the circumferential direction, each third oil storage pit extends along the circumferential direction, second oil storage pits are uniformly and alternately arranged on a portion, between the first oil storage pit and the third oil storage pits, on each concave spherical face along the circumferential direction, each second oil storage pit extends along the radial direction, and the second oil storage pits and the third oil storage pits are arranged independently in mutual dislocation. The slewing bearing spacer can contain more lubricating oil, has fine self lubricating performance, small friction coefficient, superior wear resistance, light weight and low noise, and can realize best performance of slewing bearings.
Description
Technical field
The utility model relates to the turntable bearing technical field, is specifically related to a kind of turntable bearing spacing block.
Background technique
The effect of turntable bearing retainer in turntable bearing is evenly to separate rolling element, and the performance of retainer has material impact to life-span of bearing, starting friction moment, flexibility of revolution etc.Common retainer has two kinds in turntable bearing at present, and a kind of is the segmented pressing cage, and another kind is the retainer that spacing block is formed.At present in the retainer that spacing block is formed, the structure of common spacing block is a solid cylinder, and the concave ball shape face is made at the two ends of spacing block, so as with rolling element be that steel ball adapts, steel ball promotes spacing block and advances in rolling process, slide mutually between spacing block and the raceway.In the turntable bearing working procedure, must guarantee between steel ball and the spacing block, sufficient lubricating oil fat be arranged between spacing block and the raceway, if when lubricant grease is not enough, surface of contact abrasion phenomenon will occurs, thereby reduce the life-span of bearing.The spacing block that uses is owing to be subjected to himself structural limitations at present, be between steel ball and the spacing block, the space between spacing block and the raceway is very little, so the lubricant grease amount that can fill is limited, therefore needs frequent supplemental lubrication grease, for the user brings very big inconvenience, and the maintenance cost height.
The model utility content
The purpose of this utility model provides a kind of turntable bearing spacing block, with satisfy between steel ball and the spacing block, lubricating requirement between spacing block and the raceway.
For achieving the above object, the utility model adopts following technological scheme: a kind of turntable bearing spacing block, comprise the spacing block body, the both ends of the surface of spacing block body are the concave ball shape face, the outer circumferential face of described spacing block body is the hyperboloid of one sheet, the center of described concave ball shape face is provided with the first oil storage pit, the part that keeps to the side of concave ball shape face along the circumferential direction has the 3rd oil storage pit uniformly at intervals, described the 3rd oil storage pit along the circumferential direction extends, part along the circumferential direction has the second oil storage pit uniformly at intervals between first oil storage pit of concave ball shape face and the 3rd oil storage pit, the described second oil storage pit radially extends, and described second oil storage pit and the 3rd oil storage pit independently are provided with and dislocation each other.
Further, described first oil storage pit and the described second oil storage pit independently are provided with or connect and be integral.
Described spacing block body is made by the polyamide 1010 resin material.
The outer circumferential face of the spacing block that the utility model provides is the hyperboloid of one sheet, and the clearence degree between spacing block and the raceway increases, and has therefore increased the storage volume of lubricant grease, has also reduced the area of contact between spacing block and the raceway simultaneously, has reduced friction and wear; First, second and the 3rd oil storage pit are set on the concave ball shape face at spacing block two ends, increased the voidage between steel ball and the spacing block, increased the storage volume of lubricant grease, also reduced the area of contact between rolling element and the spacing block simultaneously, reduced friction and wear, the second oil storage pit and the 3rd oil storage pit are dislocatedly distributed each other, have guaranteed that effectively rolling element all can reach lubricated fully in each sense of rotation; Simultaneously, the own wt of the spacing block that the utility model provides alleviates greatly, more helps the work of bearing, has also saved raw material.Spacing block of the present utility model is made by the polyamide 1010 resin material, has self-lubricating function, even under the situation of lubricant oil deficiency, also can play certain lubrication, has guaranteed the normal use of bearing effectively.
The spacing block that the utility model provides can hold more lubricating oil fat, and self-lubricating property is good, and friction factor is little, and wear-resisting property is superior, long service life, and in light weight, noise is low, can realize the optimum performance of turntable bearing.

Fig. 2 is the concave ball shape face schematic representation of embodiment 2 in the utility model.
Embodiment
As shown in Figure 1, the turntable bearing spacing block, the outer circumferential face of spacing block body 1 is the hyperboloid of one sheet, both ends of the surface are the concave ball shape face, the center of concave ball shape face is provided with the first oil storage pit 2, the periphery of the first oil storage pit 2 evenly is provided with the second oil storage pit 3, the along the circumferential direction spaced apart and radially extension of the second oil storage pit 3, the periphery of the second oil storage pit 3 evenly is provided with the 3rd oil storage pit 4, the along the circumferential direction spaced apart and extension along the circumferential direction of the 3rd oil storage pit 4, the second oil storage pit 3 and the 3rd oil storage pit 4 independent settings and dislocation each other, the first oil storage pit 2 and the second oil storage pit, 3 independent settings.
As shown in Figure 2, embodiment 2 with embodiment 1 difference is: the first oil storage pit 2 and the second oil storage pit 3 connect and are integral.
Claims (3)
1. turntable bearing spacing block, comprise the spacing block body, the both ends of the surface of spacing block body are the concave ball shape face, it is characterized in that: the outer circumferential face of described spacing block body is the hyperboloid of one sheet, the center of described concave ball shape face is provided with the first oil storage pit, the part that keeps to the side of concave ball shape face along the circumferential direction has the 3rd oil storage pit uniformly at intervals, described the 3rd oil storage pit along the circumferential direction extends, part along the circumferential direction has the second oil storage pit uniformly at intervals between first oil storage pit of concave ball shape face and the 3rd oil storage pit, the described second oil storage pit radially extends, and described second oil storage pit and the 3rd oil storage pit independently are provided with and dislocation each other.
