The gearbox comprises a gearbox body, a gear shaft and a linkage gear installed on the gear shaft, and is characterized in that a plurality of supporting columns used for positioning and supporting the linkage gear are arranged on the inner wall of the gearbox body, one ends of the supporting columns are connected with the inner wall of the gearbox body, and the other ends of the supporting columns are connected with the linkage gear. A linkage gear is arranged at one end of the base, a rotating disc abutting against the linkage gear is arranged at the other end of the linkage gear, mounting bases are arranged on the two sides of the linkage gear, a fixing disc used for being matched with the rotating disc is further arranged on the linkage gear, and a plurality of balls are arranged between the rotating disc and the fixing disc.

Description

Technical Field

[0001] The utility model belongs to the field of gearboxes, and in particular relates to a positioning and fixed gearbox. Background Art

[0002] Most of the gears in the gearbox are installed in the gearbox through the gear shaft. During the operation of the gearbox, the continuous meshing and collision between the gears may cause the gears to shift on the gear shaft, causing the gears to be out of fit and causing the gearbox to fail to operate normally. Summary of the invention

[0003] The purpose of the utility model is to provide a positioning and fixed gearbox in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a fixedly positioned gearbox, comprising a gearbox body, a gear shaft and a linkage gear mounted on the gear shaft, characterized in that a plurality of support columns for positioning and supporting the linkage gear are arranged on the inner wall of the gearbox body, one end of the support column is connected to the inner wall of the gearbox body, and a rotating disk abutting against the linkage gear is arranged on the other end;

[0005] Mounting seats are arranged on both sides of the linkage gear, and a fixed disk for cooperating with the rotating disk is also arranged on the linkage gear, and a plurality of balls are arranged between the rotating disk and the fixed disk.

[0006] In the above-mentioned positioning and fixing gearbox, the support column is arranged in parallel with the mounting seat, and a bearing is arranged between the support column and the mounting seat.

[0007] In the above-mentioned positioning and fixing gearbox, the balls are arranged in a circular ring shape between the rotating disk and the fixed disk.

[0008] Compared with the prior art, the present positioning and fixing gearbox fixes the position of the linkage gears through the support column, thereby avoiding gear deviation caused by the operation of the gearbox. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a main schematic diagram of the gearbox with fixed positioning;

[0010] Figure 2 It is a cross-sectional view of the gearbox with fixed positioning.

[0011] In the figure, 1. gearbox body; 2. gear shaft; 3. linkage gear; 4. support column; 5. rotating plate; 6. fixed plate; 7. ball; 8. bearing. DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the present positioning and fixed gearbox comprises a gearbox body 1, a gear shaft 2 and a linkage gear 3 mounted on the gear shaft 2. A plurality of support columns 4 for positioning and supporting the linkage gear 3 are arranged on the inner wall of the gearbox body 1. One end of the support column 4 is connected to the inner wall of the gearbox body 1, and a rotating disk 5 abutting against the linkage gear 3 is arranged on the other end.

[0014] Mounting seats are arranged on both sides of the linkage gear 3 . A fixed plate 6 for cooperating with the rotating plate 5 is also arranged on the linkage gear 3 . A plurality of balls 7 are arranged between the rotating plate 5 and the fixed plate 6 .

[0015] To be more specific, the support column 4 is arranged in parallel with the mounting seat, and a bearing 8 is arranged between the support column and the mounting seat.

[0016] To be more specific, the balls 7 are arranged in a ring shape between the rotating disk 5 and the fixed disk 6 .

[0017] During the operation of the gearbox, the support column 4 fixes the position of the linkage gear 3. When the linkage gear 3 rotates, the support column 4 and the rotating disk 5 connected to the support column 4 remain stationary. The linkage gear 3 drives the fixed disk 6 to rotate, and at the same time drives the ball 7 to rotate, thereby avoiding wear of the support column 4 during the rotation of the linkage gear 3. The bearing 8 on the outside of the mounting seat avoids wear on the side of the support column 4.

[0018] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0019] Although the terms such as gearbox body 1, gear shaft 2, linkage gear 3, support column 4, rotating plate 5, fixed plate 6, ball 7, bearing 8 are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
