Abstract
The utility model discloses a bearing roller. The bearing roller comprises a support shaft and two groups of rolling bearings which are arranged at the two ends of the support shaft, wherein each rolling bearing group comprises two rolling bearings; the two rolling bearings are jointly sleeved in a bearing bush; and the outer wall of each bearing bush is provided with a groove. According to the bearing roller disclosed by the utility model, the outer parts of the bearings are provided with the bearing bushes, and the bearing bushes are contacted with the sliding track of a guide rail, so that the guide rail can be prevented from being worn by the bearings; and the bearing bushes are preferentially made of a nylon material, the cost is low, and the anti-wearing effect is good.
Description
Technical field
The utility model relates to a kind of roller, is specifically related to a kind of bearing roller.
Background technique
At present, in mechanical manufacturing field, especially often can use roller in the electric cutting tool.Roller usually cooperates with guide rail, drives the motion of head or miscellaneous part.Roller of the prior art is comprised of the bearing at back shaft and back shaft two ends, and the outer wall of bearing directly cooperates with the dragging track of guide rail, at sliding process middle (center) bearing outer wall guide rail is caused wearing and tearing, has reduced the working life of guide rail.
The model utility content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of bearing roller that can reduce wear.
Technological scheme: for solving the problems of the technologies described above, a kind of bearing roller of the present utility model, comprise back shaft and the rolling bearing that is installed in the back shaft two ends, described rolling bearing is two groups, every group of rolling bearing is two, two rolling bearings are set in the bearing housing jointly, and the outer wall of each bearing housing is provided with groove.
The bearing housing of described bearing housing for being made by nylon material.
Beneficial effect: bearing roller of the present utility model by at the outside installation shaft bearing sleeve of bearing, makes bearing housing contact with the dragging track of guide rail, thereby can avoid bearing to the wearing and tearing of guide rail; Bearing housing is preferably the bearing housing that nylon material is made, and is not only with low cost, and it is effective to resistance to wear.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of bearing roller of the present utility model, comprise back shaft 11 and the rolling bearing 12 that is installed in back shaft 11 two ends, rolling bearing 12 is two groups, every group of rolling bearing 12 is two, two rolling bearings 12 are set in the bearing housing 13 jointly, and the outer wall of each bearing housing 13 is provided with groove 14, and the dragging track of groove 14 and guide rail is to adaptive.Wherein, the bearing housing of bearing housing 13 for being made by nylon material.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
