Abstract

The invention discloses a movable box for assembling a bearing, comprising an outer box body, an inner box body and three groups of bearing idler wheels mounted on the outer box body, wherein each bearing idler wheel comprises a supporting shaft and rolling bearings at two ends of the supporting shaft; two groups of the rolling bearings are arranged and each group comprises two rolling bearings; the two rolling bearings are commonly sleeved in the same bearing sleeve; a groove is arranged on the outer wall of each bearing sleeve; the outer box body is provided with mounting holes and the supporting shafts pass through the mounting holes to be mounted on the outer box body; and the inner box body is movably connected with the outer box body. According to the movable box for assembling the bearing disclosed by the invention, the bearing sleeves are mounted outside the bearings, so that the bearing sleeves are contacted with a sliding rail of a guide rail and the abrasion of the bearings on the guide rail is avoided; and preferably, the bearing sleeves are the bearing sleeves made of a nylon material, so that the cost is low and the abrasion resisting effect is good.

Description

Box is moved in a kind of bearing assembling

Technical field

The present invention relates to a kind of bearing assembling and move box, be specifically related to a kind of mobile box of bearing assembling that can reduce the wearing and tearing of track.

Background technique

At present, in mechanical manufacturing field, especially often can use the bearing pack dress in the electric cutting tool and move box.The bearing assembling is moved box and is usually cooperated with guide rail, drives the motion of head or miscellaneous part.Bearing assembling of the prior art is moved box and is comprised roller; Roller is made up of the bearing at back shaft and back shaft two ends; 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 mobile box of bearing assembling that can reduce the wearing and tearing of track.

Technological scheme: for solving the problems of the technologies described above; Box is moved in a kind of bearing assembling of the present invention, comprises outter box, inner box and be installed in three groups of bearing rollers on the outter box 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 outter box is provided with mounting hole, and said back shaft passes mounting hole and is installed on the outter box; Said inner box and outter box flexibly connect.

The bearing housing of bearing housing for processing by nylon material.

Said inner box is connected through bolt assembly with outter box; Said bolt assembly comprises the adjusting bolt; The screw rod of said adjusting bolt is provided with locking nut; Screw rod penetrates outter box from outside to inside, and said screw rod end and inner box are through being welded to connect, and perhaps screw rod is terminal is connected through set screw nut with inner box.

Beneficial effect: box is moved in bearing assembling of the present invention, through at the outside installation shaft bearing sleeve of bearing, bearing housing is contacted 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; Box is moved in a kind of bearing assembling of the present invention, comprises outter box 2, inner box 41 and be installed in three groups of bearing rollers 1 on the outter box 2 that bearing roller 1 comprises back shaft 12 and the rolling bearing 11 that is installed in back shaft 12 two ends; Rolling bearing 11 is two groups; Every group of rolling bearing 11 is two, and two rolling bearings 11 are set in the bearing housing 13 jointly, and the outer wall of each bearing housing 13 is provided with groove 14; Outter box 2 is provided with mounting hole, and back shaft 12 passes mounting hole and is installed on the outter box 2; Inner box 41 flexibly connects with outter box 2.

In the present embodiment; The bearing housing 13 of bearing housing 13 for processing by nylon material, inner box 41 is connected through bolt assembly with outter box 2, and bolt assembly comprises regulates bolt 42; The screw rod of regulating bolt 42 is provided with locking nut 43; Screw rod penetrates outter box 2 from outside to inside, screw rod terminal with inner box 41 through being welded to connect, perhaps screw rod is terminal is connected through set screw nut with inner box 41.

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.
