Description

Technical Field

[0001] The utility model relates to the technical field of reverse inner rings, in particular to a reverse gear ring assembly of a gearbox. Background Technique

[0002] The planetary gear set in the gearbox is divided into two parts: reverse gear and first gear. The reverse internal gear ring, as an important part of the reverse gear part, plays a crucial role in achieving the opposite direction of input and output. During the transmission process of the traditional internal gear ring, the internal gear ring is prone to radial offset, thereby reducing the positioning effect of the internal gear ring. Content of the Utility Model

[0003] The purpose of the utility model is to provide a reverse gear ring assembly of a gearbox, which can increase its positioning effect through the reverse gear ring and the reverse gear mounting plate, and effectively prevent the phenomenon of radial offset of the reverse gear ring during the transmission process.

[0004] To achieve the above purpose, a reverse gear ring assembly of a gearbox is provided, including a gear ring body, the gear ring body includes a reverse gear ring and a reverse gear mounting plate, a standard washer is arranged on the outer side of the reverse gear mounting plate, an internal thread groove is annularly arranged on the surface of the reverse gear ring, and an internal hexagonal round head screw is threadedly connected inside the internal thread groove.

[0005] According to the reverse gear ring assembly of a gearbox, the standard washer is fixedly connected with the reverse gear ring through the internal hexagonal round head screw.

[0006] According to the reverse gear ring assembly of a gearbox, twelve internal hexagonal round head screws are provided.

[0007] According to the reverse gear ring assembly of a gearbox, four openings are arranged on the surface of the standard washer.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] 1. For the reverse gear ring assembly of a gearbox, the reverse gear ring has a unified tooth shape, which simplifies the part processing process, improves the processing efficiency and reduces the tool cost.

[0010] 2. For the reverse gear ring assembly of a gearbox, by setting the reverse gear ring and the reverse gear mounting plate, its positioning effect is increased, and the phenomenon of radial offset of the reverse gear ring during the transmission process is effectively prevented.

[0011] The additional aspects and advantages of the utility model will be partially given in the following description, partially become obvious from the following description, or be understood through the practice of the utility model. Description of the Drawings

[0012] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments;

[0013] Figure 1 is a three-dimensional view of a reverse gear ring assembly of a transmission for the present utility model;

[0014] Figure 2 For the present utility model Figure 1 is a sectional view taken along line B-B.

[0015] In the figure: 1, reverse gear ring; 2, reverse gear mounting disc; 3, standard washer; 4, hexagon socket round head screw. Specific embodiments

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0017] Please refer to Figure 1-2 , an embodiment of the present utility model provides a technical solution: a reverse gear ring assembly of a transmission, including a gear ring body, the gear ring body includes a reverse gear ring 1 and a reverse gear mounting disc 2. By setting the reverse gear ring 1 and the reverse gear mounting disc 2, its positioning effect is increased, effectively preventing the reverse gear ring 1 from radially shifting during transmission, and the reverse gear ring 1 has a unified tooth profile, simplifying the part processing process, improving the processing efficiency and reducing the tool cost. A standard washer 3 is provided on the outer side of the reverse gear mounting disc 2, and an internal thread groove is annularly formed on the surface of the reverse gear ring 1, and a hexagon socket round head screw 4 is threadedly connected inside the internal thread groove.

[0018] The standard washer 3 is fixedly connected to the reverse gear ring 1 by the hexagon socket round head screw 4. There are twelve hexagon socket round head screws 4, and four openings are formed on the surface of the standard washer 3.

[0019] The above has described the embodiments of the present utility model in detail in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the purpose of the present utility model within the knowledge scope of those of ordinary skill in the relevant technical field.
