Technical Field
[0001] The utility model relates to the technical field of planetary reduction starters, in particular to a gear mounting structure for a planetary reduction starter. Background Technique
[0002] Planetary reduction starters are mainly used to start automobile engines. The planetary gears rotate around the sun gear and roll along the internal gear ring at the same time, forming a "revolution" motion. This design effectively converts the high-speed and low-torque motor power into low-speed and high-torque output power, which meets the requirements during engine starting. Planetary reduction starters are an essential component in vehicles such as automobiles. Their high-precision and high-reliability transmission devices ensure that the engine can start smoothly and operate stably.
[0003] During the installation of the sun gear of the planetary gear, there is usually no position centering device, which easily causes the concentricity between the installed sun gear and the connecting shaft to deviate. In the planetary gear system, concentricity directly affects the meshing effect and transmission efficiency of the gears. If the concentricity is not good, it will lead to problems such as poor gear meshing, increased noise, and accelerated wear, and may even cause equipment failures. Therefore, a gear mounting structure for a planetary reduction starter is proposed to solve the above problems. Summary of the Utility Model

[0007] One of the clamping tables is provided with a mounting frame, on which a driving motor is arranged. The output shaft of the driving motor is fixedly connected with a driving gear, and the driving gear is in driving connection with the connecting component.
[0008] Further, the connecting component includes a sleeve, a sliding cylinder is slidably connected to the sleeve, and connecting toothed rings are fixedly connected to the opposite sides of the sleeve and the sliding cylinder. The connecting toothed rings are meshed with the driving gear and a plurality of driven gears.
[0009] Further, a limiting rod is fixedly connected to the sliding cylinder, a limiting groove is formed in the inner peripheral wall of the sleeve, and the limiting rod is slidably connected with the limiting groove.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1:

One end of the second threaded rod 24 penetrates through the clamping table 2 and is fixedly connected to a clamping rod 25. A limiting block 26 is arranged on the clamping rod 25, and the limiting block 26 is slidably connected to the clamping table 2. An installation frame 14 is arranged on one of the clamping tables 2. A driving motor 15 is arranged on the installation frame 14. The output shaft of the driving motor 15 is fixedly connected to a driving gear 16, and the driving gear 16 is in transmission connection with the connecting component 3. The connecting component 3 includes a sleeve 31. A sliding cylinder 33 is slidably connected to the sleeve 31. Connecting tooth rings 32 are fixedly connected to the opposite sides of the sleeve 31 and the sliding cylinder 33.

A limiting rod 34 is fixedly connected to the sliding cylinder 33, and a limiting groove 36 is formed in the inner peripheral wall of the sleeve 31. The limiting rod 34 is slidably connected to the limiting groove 36. This connection method effectively ensures that during the use process, it can effectively achieve the effect of simultaneously driving multiple driven gears 22, so that the clamping rod 25 can produce the displacement effect of the same distance. During the displacement of the clamping rod 25, it can effectively achieve the effect of centering and clamping the sun gear 17 and the gear ring 18.
[0025] It should be noted that the displacement directions of the multiple clamping rods 25 in this embodiment are all towards the center of the clamping table 2 for displacement.
[0026] The fixed component 4 includes a fixed rod 41. The fixed rod 41 is fixedly connected to the two clamping tables 2. Limiting rings 42 are arranged on both fixed rods 41. The two limiting rings 42 are rotatably connected to the sleeve 31 and the sliding cylinder 33. By arranging the fixed rod 41 and the limiting rings 42, it can effectively achieve the effect of limiting the sleeve 31 and the sliding cylinder 33 during the use process.
[0027] As a preferred technical solution in this embodiment: During actual use, the staff first place the sun gear 17 in a clamping table 2 and the ring gear 18 in another clamping table 2. Then, the drive motor 15 can be controlled to drive the drive gear 16 to rotate. During the rotation of the drive gear 16, it can drive the connecting ring gear 32 to drive.

During the rotation of the sliding cylinder 33, it can drive another connecting ring gear 32 to rotate. At this time, both connecting ring gears 32 rotate. During the rotation of both connecting ring gears 32, it can drive multiple driven gears 22 to rotate simultaneously. During the simultaneous rotation of multiple driven gears 22, it can drive multiple second threaded rods 24 and clamping rods 25 to displace inward, thereby achieving the centering clamping effect on the sun gear 17 and the ring gear 18.
[0028] Embodiment 2:
[0029] Please refer to Figure 1 , to achieve a good installation effect, a first threaded rod 11 is also rotatably connected in the installation groove in this embodiment. The first threaded rod 11 is threadedly connected to a clamping table 2 that is slidably connected to the installation groove. One end of the first threaded rod 11 penetrates through one side surface of the installation table 1 and is fixedly connected to a rotating handle 12. A guiding table 13 for guiding the first threaded rod 11 is also provided in the installation groove.
[0030] As a preferred technical solution in this embodiment: When the staff achieves centering clamping of the sun gear 17 and the ring gear 18 through the clamping table 2, the rotating handle 12 can be rotated to drive the first threaded rod 11 to rotate. During the rotation of the first threaded rod 11, it can drive the clamping table 2 to displace. During the displacement of the clamping table 2, it can drive the sleeve 31 and the sliding cylinder 33 to slide relative to each other. During their relative sliding, it can drive the sun gear 17 to displace towards the ring gear 18, so that the sun gear 17 can be inserted between the planetary gears 19. This method effectively guarantees the installation effect during its use and avoids the occurrence of deviation during installation.
[0031] The working principle of the above embodiment is:
[0032] 1. First, the staff places the sun gear 17 in a clamping table 2 and the ring gear 18 in another clamping table 2. Then, by controlling the driving motor 15, the driving gear 16 can be driven to rotate. During the rotation of the driving gear 16, it can drive the connecting tooth ring 32 to drive. First, it can drive the sleeve 31 to rotate. During the rotation of the sleeve 31, it can drive the sliding cylinder 33 that is slidably connected to it to rotate. During the rotation of the sliding cylinder 33, it can drive the other connecting tooth ring 32 to rotate. At this time, both connecting tooth rings 32 rotate. During the rotation of both connecting tooth rings 32, it can drive multiple driven gears 22 to rotate simultaneously. During the simultaneous rotation of multiple driven gears 22, it can drive multiple second threaded rods 24 and clamping rods 25 to move inward, thereby achieving the centering clamping effect on the sun gear 17 and the ring gear 18.
[0033] 2. After the staff achieves centering clamping of the sun gear 17 and the ring gear 18 through the clamping table 2, the first threaded rod 11 can be driven to rotate by rotating the rotating handle 12. During the rotation of the first threaded rod 11, it can drive the clamping table 2 to move. During the movement of the clamping table 2, the sleeve 31 and the sliding cylinder 33 can slide relative to each other. During their relative sliding, it can drive the sun gear 17 to move towards the ring gear 18, so that the sun gear 17 can be inserted between the planetary gears 19. This method effectively ensures the installation effect during its use and avoids the occurrence of deviation during installation.
