Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of locomotive maintenance equipment, specifically relating to an auxiliary device for the maintenance of driven gears in rail locomotives. Background Technology
[0002] The driven gear of a rail locomotive is a core component of the drive system, and its normal operation is crucial to the locomotive's performance. During routine maintenance and repair, the driven gear requires procedures such as tooth surface inspection, grinding, hole inspection, and application of lubricating oil before press-fitting. However, the driven gear component is heavy, making rotational maintenance difficult without support. Furthermore, rotating it on the ground poses quality and safety hazards, easily causing collisions and injuries. This presents major problems including complex operation, low work efficiency, potential damage risks, and high manpower requirements. Therefore, there is a need to develop an auxiliary device for gear maintenance, which is of great significance for simplifying the operation process, improving work efficiency, and ensuring maintenance quality. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to design an auxiliary device for the maintenance of driven gears of rail locomotives, in order to solve the problems mentioned in the background technology, such as complicated operation, low work efficiency and risk of gear damage.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for the maintenance of driven gears of rail locomotives, comprising a support leg, a base plate, a frame, a rotary support assembly, a limiting assembly, and a lighting assembly. The base plate is a rectangular plate structure, with a support leg on the bottom surface of the base plate and a frame on the upper surface of the base plate. The bottom of the frame is provided with a rotary support assembly for supporting the driven gear, and the upper part of the frame is provided with a limiting assembly for limiting the end face of the driven gear. The frame is also provided with a lighting assembly.
[0005] The frame consists of four units, each located at one of the four corners of the upper surface of the base plate. Two adjacent units form a group, and the units within the same group are symmetrical. The two groups of units are also symmetrical. Each frame includes uprights, connecting rods, and reinforcing ribs. There are four uprights, and their lower ends are fixed to the base plate to form a rectangular frame. Reinforcing ribs are provided between two adjacent uprights, and connecting rods are provided between the two outer uprights. A rotating support assembly is provided on the bottom surface of the frame, and symmetrical limiting assemblies are provided on the inner side of the upper part of the frame. A lighting assembly is provided between two units within the same group.
[0006] The rotary support assembly includes a base, bearing seats A, and a support roller. The base is composed of two oppositely arranged "C"-shaped plates. The base is provided with mutually symmetrical bearing seats A, and a support roller is provided between the two bearing seats A. The support roller is used to support the lower part of the driven gear, and through cooperation with the bearing seats A, it enables the driven gear to rotate for maintenance.
[0007] The limiting assembly includes bearing seats B and limiting rollers. There are multiple bearing seats B, which are respectively set on the inner side of each column relative to the frame. Limiting rollers are provided between two horizontally adjacent bearing seats B. The distance between two limiting rollers set on the same frame is slightly greater than the thickness of the driven gear.
[0008] The lighting assembly includes a mounting rod, a clamp, and a spotlight. The mounting rod is positioned between adjacent columns on the inner sides of two frames. A clamp is fitted onto the middle of the mounting rod, and a spotlight is mounted on the clamp to illuminate and inspect the inner side of the driven gear.
[0009] Both the support roller and the limiting roller are made of nylon to avoid damage to the driven gear.
[0010] The beneficial effects of this utility model are: this device can simultaneously inspect two driven gears. The driven gears can rotate, which makes it convenient for workers to inspect the gear tooth surface, gear hole, and apply lubricating oil during gear pressing. The operation is simple and improves work efficiency. Attached Figure Description

Two horizontally adjacent frames 3 form a group, and the two frames 3 in the same group are symmetrical to each other. The two groups of frames 3 are also symmetrical to each other. Each frame 3 includes a column 301, a connecting rod 302, and a reinforcing rib 303. There are four columns 301. The lower ends of the four columns 301 are fixed to the base plate 1 to form a rectangular frame. A reinforcing rib 303 is provided between two horizontally adjacent columns 301. A connecting rod 302 is provided between two columns 301 on the outer side. A rotating support assembly 4 is provided on the bottom surface inside the frame 3. A limiting assembly 5 is symmetrically provided on the inner side of the upper part of the frame 3. A lighting assembly 6 is provided between two frames 3 in the same group. The rotating support assembly 4 includes a base 401, bearing seats A402, and a support roller 403. The base 401 is composed of two oppositely arranged "C"-shaped plates. Symmetrical bearing seats A402 are provided on the base 401, and a support roller 403 is positioned between the two bearing seats A402. The support roller 403 supports the lower part of the driven gear and, through its cooperation with the bearing seats A402, allows the driven gear to rotate for maintenance. The limiting assembly 5 includes bearing seats B501 and limiting rollers 502. Multiple bearing seats B501 are provided, each located on the inner side of each column 301 relative to the frame 3. A limiting roller 502 is positioned between any two laterally adjacent bearing seats B501. The distance between two limiting rollers 502 on the same frame 3 is slightly greater than the thickness of the driven gear.

The support roller 403 and the limiting roller 502 are both made of nylon to prevent damage to the driven gear.
[0020] When using this utility model: Gear surface inspection, gear hole inspection and grinding operation: Use an overhead crane to place the driven gear on this auxiliary device, so that the lower teeth of the driven gear are placed on the support rollers 403 of the two rotating support components 4 of the same frame 3. Adjust the lighting component 6 so that the spotlight 603 illuminates the inner side of the driven gear. The operator begins to inspect and grind the gear teeth and gear holes. Under the action of the support rollers 403 and the limit rollers 502, the driven gear is rotated until all tooth surface inspection, gear hole inspection and grinding operations are completed and then the next process is entered. Applying lubricating oil before gear pressing: After inspection and grinding, the operator applies lubricating oil to the driven gear while rotating it until the lubricating oil application is completed. Then, the operator uses an overhead crane to lift the lubricated driven gear to the installation position for pressing. This auxiliary tooling has two sets of frames 3, which can simultaneously inspect, grind, and apply lubricant to two driven gears. It is simple to operate and easy to use, greatly improving work efficiency.
