Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] Such as figure 1 , 2 As shown in and 3, an anti-rotation internal ring gear includes a main body 1, a tooth shape 1a is provided on the wall of the central hole of the main body 1, and an annular groove 1b is opened on one end of the outer surface of the main body 1. At the same time, a group of small axial ridges 1c are uniformly distributed along the circumference of the outer surface of the body 1, one end of the small axial ridges 1c communicates with the annular groove 1b, and the other end of the small axial ridges 1c opens to the body 1 the other end of the In addition, the cross-section of the axial small convex strip 1c is square, and its protrusion height is 1-2mm, and the distance between the two axial small convex strips 1c of the bell is 1-3mm, and the axial small convex strip 1c It is an integral structure with the body 1.

Abstract

The invention discloses an anti-rotation ring gear, which comprises a body (1); the wall of the center hole of the body is provided with tooth profiles (1a), and a ring groove (1b) is formed in one end of the outer ring surface of the body (1). The anti-rotation ring gear is characterized in that a group of axial small raised lines (1c) is also evenly distributed along the circumferential direction of the outer ring surface of the body (1); one end of each axial small raised line is communicated with the ring groove (1b), and the other end of each axial small raised line (1c) is opened to the other end of the body (1). The outer wall of the anti-rotation ring gear disclosed by the invention is additionally provided with the axial small raised lines, indentations can be formed on the hole of a mounting hole by the axial small raised lines, and thus, the anti-rotation goal can be achieved through the axial small raised lines and the indentations, and therefore the defect that the traditional ring gear is easy to rotate is overcome very well by small changes.

Description

technical field [0001] The invention belongs to the field of ring gears, and in particular relates to an anti-rotation inner ring gear. Background technique [0002] The inner ring gear is a widely used component, which is press-fitted into the mounting holes of other components during assembly. Because the outer circular surface of the inner ring gear is a smooth surface, the inner ring gear is easy to rotate after assembly, so that the requirement of reliable installation cannot be achieved. Therefore, it is urgent to solve the above-mentioned technical problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a securely installed anti-rotation ring gear. [0004] The technical scheme of the present invention is as follows: an anti-rotation internal ring gear, including a body (1), the hole wall of the center hole of the body is provided with a tooth shape (1a), and one end of the outer surface of the body (1)...
