Abstract
The invention discloses a bearing assembly, comprising a frame and a bearing roller arranged on the frame, wherein the bearing roller comprises a support shaft and rolling bearings arranged on two ends of the support shaft, the rolling bearings are divided into two groups, each group comprises two rolling bearings, every two rolling bearings are sleeved in one bearing sleeve together, the outer wall of each bearing sleeve is provided with a groove; and the frame comprises a mounting hole, and the support shaft is arranged on the frame after passing through the mounting hole. Through installing the bearing sleeves outside the bearings, so that the bearing sleeves are contacted with a sliding track of a guide rail, and further, the wear of the guide rail, caused by the bearings, can be reduced; and as the bearing sleeves are preferably made of a nylon material, not only is the cost low, but also the wear resistance effect is good.
Description
Technical field
The present invention relates to a kind of bearing assembly body, be specifically related to a kind of bearing assembly body that can reduce the wearing and tearing of track.
Background technique
At present, in mechanical manufacturing field, especially often can use bearing pack dress body in the electric cutting tool.The bearing assembly body usually cooperates with guide rail, drives the motion of head or miscellaneous part.Bearing assembly body of the prior art comprises roller, and roller is made up 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.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the existing technology, the present invention provides a kind of bearing assembly body that can reduce the wearing and tearing of track.
Technological scheme: for solving the problems of the technologies described above; A kind of bearing assembly body of the present invention comprises framework and is installed in the bearing roller on the framework that said bearing roller comprises back shaft and the rolling bearing that is installed in the back shaft two ends; Said rolling bearing is two groups; Every group of rolling bearing is two, and two rolling bearings are set in the bearing housing jointly, and the outer wall of each bearing housing is provided with groove; Said framework comprises mounting hole, and said back shaft passes mounting hole and is installed on the framework.
The bearing housing of said bearing housing for processing by nylon material.
Said bearing roller is three groups.
Beneficial effect: bearing assembly body of the present invention through at the outside installation shaft bearing sleeve of bearing, makes bearing housing contact with the dragging track of guide rail, thereby can avoid the wearing and tearing of bearing to guide rail; Bearing housing is preferably the bearing housing that nylon material is processed, and is not only with low cost, and it is effective to resistance to wear.
Description of drawings
Fig. 1 is a fractionation structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As shown in Figure 1; A kind of bearing assembly body of the present invention comprises framework 2 and is installed in the bearing roller 1 on the framework 2 that bearing roller 1 comprises 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, and 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; Framework 2 comprises mounting hole, and back shaft 11 passes mounting hole and is installed on the framework 2.In the present embodiment, the bearing housing 13 of bearing housing 13 for processing by nylon material.Bearing roller 1 is three groups.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
