Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer installation, in particular to an auxiliary structure for installing a planetary gear speed reducer for an automobile. Background Art

[0002] In the automotive industry, planetary gear reducers, as a precision reduction motor, are widely used in various transmission systems due to their high efficiency, high rigidity and high precision. Planetary gear reducers are usually composed of key components such as planetary gears, sun gears, inner ring gears, planetary carriers and transmission sources (such as motors or electric motors). The precise coordination and efficient transmission of these components enable planetary gear reducers to meet the transmission needs in different fields and scenarios.

[0003] The gear set of the existing planetary gear reducer is installed in the reducer housing through the positioning gear ring. The gears are very tightly fitted, which makes installation inconvenient.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] An auxiliary structure for mounting an automobile planetary gear reducer includes an auxiliary platform 1, a reducer body 2 is provided on the top of the auxiliary platform 1, a gear auxiliary mounting mechanism 3 is provided on the top of the reducer body 2, an auxiliary pressing mechanism 4 is provided on the top of the auxiliary platform 1, and a positioning mechanism 5 is provided on the top of the auxiliary platform 1;

[0031] The gear auxiliary installation mechanism 3 includes an auxiliary sleeve 31, corresponding teeth 32, a docking inner gear ring 33, a positioning rod 34 and a positioning hole 35. The auxiliary sleeve 31 is arranged at the top of the reducer body 2, and the auxiliary sleeve 31 is sleeved and matched with the reducer body 2. The corresponding teeth 32 are arranged on the inner wall of the auxiliary sleeve 31, and the corresponding teeth 32 are adapted to the gear ring of the reducer body 2. The three docking inner gear rings 33 are fixedly connected to the top of the auxiliary sleeve 31, and the docking inner gear rings 33 are adapted to the corresponding teeth 32. The positioning rod 34 is arranged on the side wall of the auxiliary sleeve 31, and the positioning hole 35 is opened on the side wall of the reducer body 2, and the positioning rod 34 is adapted to the positioning hole 35.

[0032] Specifically, such as Figure 2 and Figure 3 As shown, the positioning mechanism 5 includes a threaded seat 51, a threaded rod 52 and a positioning block 53. The threaded seat 51 is fixedly connected to the top of the auxiliary table 1, the threaded rod 52 is threadedly connected to the middle of the threaded seat 51, and the positioning block 53 is movably set at one end of the threaded rod 52. The side wall of the positioning block 53 is arc-shaped, and the side wall of the positioning block 53 is in contact with the reducer body 2.

[0033] Specifically, such as Figure 2 As shown, two guide rods 6 are fixedly connected to the side wall of the positioning block 53 , and two guide blocks 7 are fixedly connected to both ends of the top of the auxiliary platform 1 , and the guide blocks 7 are movably connected to the guide rods 6 .

[0034] Specifically, such as Figure 3 As shown, a mounting groove 9 is formed on the side wall of the positioning block 53 , and a rubber protective pad 10 is bonded to the inner wall of the mounting groove 9 .

[0035] Specifically, such as Figure 5As shown, a mounting ring 11 is fixedly connected to the top of the reducer body 2 , and a positioning pin 12 is movably provided in the middle of the mounting ring 11 , and the positioning pin 12 is plugged into and matched with the auxiliary platform 1 .

[0036] Specifically, such as Figure 1 and Figure 2 As shown, an auxiliary support block 13 is provided on the top of the auxiliary table 1 , and the auxiliary support block 13 is in contact with the reducer body 2 .

[0037] First, place the reducer body 2 on the top of the auxiliary table 1. At this time, the auxiliary support block 13 supports the reducer body 2. The reducer body 2 is positioned by installing the lifting ring 11 and the positioning pin 12. Then, the threaded rod 52 and the threaded seat 51 are rotated. At this time, the threaded rod 52 pushes the positioning block 53 to move. In this process, the guide rod 6 guides the movement of the positioning block 53. The two positioning blocks 53 clamp and position the reducer body 2. When the reducer body 2 is assembled and installed, the auxiliary sleeve 31 is sleeved on the top of the reducer body 2 and placed in the positioning hole 35 through the positioning rod 34. The auxiliary sleeve 31 can be positioned so that the corresponding teeth 32 are adapted to the inner ring gear of the reducer body 2. When installing the planetary gear, it is only necessary to place the planetary gear into the docking inner ring gear 33. In this process, the planetary gear and the inner ring gear of the reducer body 2 are quickly positioned and installed, which improves the efficiency of the installation of the reducer body 2.

[0038] Specifically, such as Figure 2 As shown, the auxiliary pressing mechanism 4 includes a top frame 41, an electric push rod 42 and a pressure plate 43.

[0040] During use, after the planetary gear is placed in the reducer body 2, the electric push rod 42 is started to push the pressure plate 43 downward. At this time, the pressure plate 43 pushes the planetary gear tightly into the reducer body 2. The rubber head 8 can prevent the pressure plate 43 from causing damage to the planetary gear, thereby assisting in the installation of the reducer body 2.

[0041] By adopting the above technical solution, the problem that the existing installation structure of the planetary gear reducer is not convenient for quickly positioning and installing the planetary wheels and the inner ring gear is solved. Since the teeth of multiple planetary wheels and the inner ring gear are difficult to quickly connect, the planetary wheels are difficult to install quickly.

[0042] Working principle: When using this application, first, place the reducer body 2 on the top of the auxiliary table 1. At this time, the auxiliary support block 13 supports the reducer body 2. The reducer body 2 is positioned by installing the lifting ring 11 and the positioning pin 12. Then, the threaded rod 52 and the threaded seat 51 are rotated. At this time, the threaded rod 52 pushes the positioning block 53 to move. In this process, the guide rod 6 guides the movement of the positioning block 53. The two positioning blocks 53 clamp the reducer body 2 for positioning. When the reducer body 2 is assembled and installed, the auxiliary sleeve 31 is placed on the reducer body 2. It is sleeved on the top of the reducer body 2 and placed in the positioning hole 35 through the positioning rod 34. The auxiliary sleeve 31 can be positioned so that the corresponding teeth 32 are adapted to the inner ring gear of the reducer body 2. When installing the planetary gear, it is only necessary to place the planetary gear into the docking inner ring gear 33, and start the electric push rod 42 to push the pressure plate 43 downward. At this time, the pressure plate 43 pushes the planetary gear tightly into the interior of the reducer body 2. The rubber head 8 can prevent the pressure plate 43 from causing damage to the planetary gear. In this way, it can assist in the installation of the reducer body 2.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
