Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of planetary carriers, in particular to an adjustable planetary carrier. Background Art
[0002] The planetary carrier is one of the main components of a planetary gear transmission. It is usually mounted on the planetary axle or bearing. It is a complex part with three common structural forms: double-side plate integral type, double-side plate separate type and single-side plate type. The planetary carrier must have sufficient strength and rigidity to ensure the stability and load-bearing capacity of the gear transmission. It is widely used in mechanical transmission fields such as industrial machinery, automobiles, aerospace, etc.
[0003] A Chinese patent with publication number "CN221145265U" discloses a planetary carrier, including a transmission module and a dustproof module. The transmission module includes a planetary carrier body, a shell sleeved on the bottom of the planetary carrier body, and a top plate sleeved on the top of the planetary carrier body. The dustproof module includes a rubber sleeve detachably connected between the planetary carrier body and the shell, a ring body interference-sleeved on the outside of the rubber sleeve, three gaskets movably sleeved on the top of the planetary carrier body, and three nuts connected to the rubber sleeve.
[0004] However, this planetary carrier still has some shortcomings. When installing the planetary carrier, the length of the planetary carrier cannot be adjusted due to the length regulations of the planetary carrier. If the length is long, the user needs to widen the planetary carrier installation point by stretching. When disassembling the planetary carrier, it needs to be disassembled in the same way. While it is difficult to adjust the length of the planetary carrier, it also reduces the efficiency of the subsequent disassembly and maintenance of the planetary carrier. Utility Model Content
[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide an adjustable planetary carrier to solve the problems raised in the above background technology.
[0006] The above technical objectives of the present invention are achieved through the following technical solutions:
[0007] The adjustable planetary carrier includes a shell, a mounting shell is slidably connected to the inner wall of the shell, a first slide groove matching the mounting shell is opened on the inner wall of the shell, the mounting shell is slidably connected to the inner wall of the shell through the first slide groove, a planetary carrier body is installed at the inner bottom end of the mounting shell, the top of the planetary carrier body is threadedly connected to a top cover, a transmission module is installed on the top of the top cover, a protective shell is slidably connected to the outer wall of the shell, a second slide groove matching the protective shell is opened on the outer wall of the shell, the protective shell is slidably connected to the outer wall of the shell through the second slide groove, the top of the protective shell is fixedly connected to a connecting plate, the connecting plate is threadedly connected to the top of the top cover, a slot is opened on the outer wall of the shell, a spring buckle is clamped on the inner side of the slot, the bottom end of the protective shell is fixedly connected to a limiting block, a card hole matching the spring buckle is opened on the front side of the limiting block, and the spring buckle is clamped on the inner side of the card hole.
[0008] As an optimal technical solution, the top of the planetary frame protrudes from the top of the top cover, the top of the planetary frame is threadedly connected to a nut, the bottom of the nut is in contact with the top of the top cover, and the top cover is fixed to the top of the planetary frame through the nut thread.
[0009] As an optimal technical solution, a through hole is opened at the top of the top cover, which passes through the top cover. Transparent glass is fixedly connected to the inside of the through hole, covering the inside of the through hole. The position of the transparent glass is symmetrical with that of the planetary carrier.
[0010] As an optimal technical solution, a screw hole is provided at the top of the connecting plate, and the screw holes pass through the top of the connecting plate and the top cover. The inner side of the screw hole is threadedly connected to a bolt, and the bottom end of the bolt is threadedly connected to the inside of the top cover through the screw hole, and the connecting plate is threadedly connected to the top of the top cover through the screw hole and the bolt.
[0011] As an optimal technical solution, a circular groove is provided at the inner bottom end of the outer shell, and a telescopic block is fixedly connected to the inner bottom end of the circular groove. The telescopic block is fixedly connected to the four sides of the inner bottom end of the circular groove near the corners, and the bottom end of the mounting shell is fixedly connected to a connecting block matching the telescopic block, and the top end of the telescopic block is clamped to the bottom end of the connecting block.
[0012] As a preferred technical solution, a rubber pad is fixedly connected to the inner bottom end of the circular groove, the rubber pad is located close to the inner side of the telescopic block, and the top end of the rubber pad is in contact with the bottom end of the mounting shell.
[0013] As a preferred technical solution, an anti-corrosion layer is coated on the outer wall of the shell. The thickness of the anti-corrosion layer on the outer wall of the shell is one centimeter, and the anti-corrosion layer on the outer wall of the shell covers the shell.
[0014] In summary, the present invention has the following beneficial effects:
[0015] First, during use, in order to facilitate the installation of the planetary frame, the user can slide the protective shell through the second slide groove. Since the connecting plate is threadedly fixed to the top of the top cover, when the protective shell moves upward, the top cover will be pulled together. When the top cover is pulled, the entire installation shell will also move upward along the first slide groove, which can facilitate the user to adjust the installation length of the planetary frame. When the adjustment is completed, the user can press the spring buckle and use the rebound principle of the spring buckle to clip it into the card hole, thereby effectively limiting the position of the protective shell. While achieving the convenience of adjusting the length of the planetary frame, it is also more convenient for the user to disassemble and maintain it later.
[0016] Secondly, when the mounting shell needs to be disassembled later, first press the spring clip to make it rebound into the slot, then unscrew the bolt through the thread principle, and finally directly pull out the protective shell through the second slide groove. After the protective shell is pulled out, the user only needs to pull the entire mounting shell directly out of the outer shell along the first slide groove, which is convenient for the user to disassemble the mounting shell individually and also helps the user to check and maintain the planetary carrier inside the mounting shell later. The installation of the telescopic block can provide secondary support and limit to the bottom end of the mounting shell without hindering the adjustment of the height of the mounting shell, thereby effectively improving the stability of the height adjustment of the mounting shell and the later disassembly.

A slot 21 is provided, and a spring clip 22 is clamped on the inner side of the slot 21. The bottom end of the protective shell 15 is fixedly connected to the limit block 19. The front side of the limit block 19 is provided with a clamping hole 20 that matches the spring clip 22. The spring clip 22 is clamped on the inner side of the clamping hole 20. The planetary carrier is a key component in the planetary gear transmission device. Its basic structure is complex and diverse. Common planetary carrier structures include double-side plate integral type, double-side plate separate type and single-side plate type. These structures depend to a large extent on the use function, manufacturing process and assembly conditions of the planetary gear transmission device. The planetary carrier has sufficient strength and rigidity to ensure the stability and load-bearing capacity of the gear transmission. In addition, a reasonable planetary carrier structure should also be easy to process and assemble to meet the needs of actual applications.
[0025] refer to Figures 1 to 3 The top of the planetary carrier body 3 protrudes from the top of the top cover 4, and the top of the planetary carrier body 3 is threadedly connected with a nut 5. The bottom end of the nut 5 is in contact with the top of the top cover 4, and the top cover 4 is threadedly fixed to the top of the planetary carrier body 3 through the nut 5. Due to the existence of the nut 5, the mounting shell 2 of the nut 5 effectively fixes the position of the top cover 4 to prevent the top cover 4 from being displaced. When the top cover 4 needs to be removed, just unscrew the nut 5. It is also convenient for the user to check or maintain the planetary carrier body 3 inside the mounting shell 2 later.
[0026] refer to Figure 1 and Figure 3 A through opening 7 is provided at the top of the top cover 4, and the through opening 7 passes through the top cover 4. A transparent glass 8 is fixedly connected to the inner side of the through opening 7, and the transparent glass 8 covers the inner side of the through opening 7. The position of the transparent glass 8 is symmetrical with the position of the planetary carrier 3. Due to the opening 7, the user can directly view the inner side of the mounting shell 2 through the transparent glass 8 when the top cover 4 is removed, which is beneficial for the user to observe the operation of the planetary carrier 3 at any time in the later stage.
[0027] refer to Figures 1 to 5, a screw hole 17 is provided at the top of the connecting plate 16, and the screw holes 17 all pass through the top of the connecting plate 16 and the top cover 4. The inner side of the screw hole 17 is threadedly connected with a bolt 18. The bottom end of the bolt 18 is threadedly connected to the inside of the top cover 4 through the screw hole 17. The connecting plate 16 is threadedly connected to the top of the top cover 4 through the screw hole 17 and the bolt 18. A circular groove 10 is provided at the bottom end of the inner side of the shell 1. The inner bottom end of the circular groove 10 is fixedly connected with a telescopic block 11. The telescopic block 11 is fixedly connected to the four sides of the inner bottom end of the circular groove 10 near the corners. The bottom end of the mounting shell 2 is fixedly connected with a connecting block 9 that matches the telescopic block 11. The top of the telescopic block 11 is snapped into the bottom end of the connecting block 9. When the installation needs to be installed later When the shell 2 is disassembled, first press the spring clip 22 to make it rebound into the slot 21, and then unscrew the bolt 18 through the thread principle, and finally the protective shell 15 can be directly pulled out through the second slide groove 14. After the protective shell 15 is pulled out, the user only needs to pull the entire mounting shell 2 directly out of the outer shell 1 along the first slide groove 13, which not only facilitates the individual disassembly of the mounting shell 2, but also facilitates the user to check and maintain the planetary carrier 3 inside the mounting shell 2 later. The installation of the telescopic block 11 can provide secondary support and limitation to the bottom end of the mounting shell 2 without hindering the adjustment of the height of the mounting shell 2, thereby effectively improving the stability of the height adjustment and later disassembly of the mounting shell 2.
[0028] refer to Figure 4 The inner bottom end of the circular groove 10 is fixedly connected with a rubber pad 12. The rubber pad 12 is located on the inner side close to the telescopic block 11. The top of the rubber pad 12 is in contact with the bottom end of the mounting shell 2. Due to the presence of the rubber pad 12, the rubber pad 12 is a rubber product with good anti-slip ability and rubber shock absorption ability. At the same time, it also has good elasticity, so that the top end and the bottom end of the mounting shell 2 can always be kept in contact, which can effectively improve the stability of the fixed position of the mounting shell 2.
[0029] refer to Figure 1 The outer wall of the shell 1 is coated with an anti-corrosion layer. The thickness of the anti-corrosion layer on the outer wall of the shell 1 is one centimeter. The anti-corrosion layer on the outer wall of the shell 1 covers the shell 1. Due to the existence of the anti-corrosion layer, the anti-corrosion layer is an anti-corrosion coating with good wear resistance and corrosion resistance, thereby effectively improving the service life of the outer wall of the shell 1.
[0030] Principle and advantages of use: When installing the position of the planetary carrier 3, first slide the protective shell 15 through the second slide groove 14. When the protective shell 15 moves, its top cover 4 will also be pulled together. When the top cover 4 is pulled, the entire installation shell 2 will also move upward along the first slide groove 13. Adjust the position of the top cover 4 according to needs. When the adjustment is completed, press the spring buckle 22 and use the rebound principle of the spring buckle 22 to clip it into the card hole 20, thereby effectively limiting the position of the protective shell 15. It is convenient to adjust the installation of the planetary carrier 3. At the same time of installing the length, it is also more convenient for the user to disassemble and maintain it later. Due to the existence of the nut 5, the mounting shell 2 of the nut 5 effectively fixes the position of the top cover 4 to prevent the top cover 4 from being displaced. When the top cover 4 needs to be removed, the nut 5 can be unscrewed. At the same time, it is also convenient for the user to check or maintain the planetary carrier 3 inside the mounting shell 2 later. Due to the opening 7, the user can directly check the inside of the mounting shell 2 through the transparent glass 8 when the top cover 4 is removed, which is convenient for the user to check or maintain it later. The operation of the planetary carrier 3 is constantly observed. When the mounting shell 2 needs to be disassembled later, the spring buckle 22 is first pressed to make it rebound into the slot 21, and then the bolt 18 is unscrewed through the thread principle, and finally the protective shell 15 can be directly pulled out through the second slide groove 14. After the protective shell 15 is pulled out, the user only needs to pull the entire mounting shell 2 directly out of the outer shell 1 along the first slide groove 13, which is convenient for the user to disassemble the mounting shell 2 individually and also facilitates the user to check and maintain the planetary carrier 3 inside the mounting shell 2 later. The installation of the telescopic block 11 can provide secondary support and limit to the bottom end of the mounting shell 2 without hindering the height adjustment of the mounting shell 2, thereby effectively improving the stability of the height adjustment and later disassembly of the mounting shell 2. Due to the presence of the rubber pad 12, the rubber pad 12 is a rubber product with good anti-slip and rubber shock absorption capabilities. At the same time, it also has good elasticity, so that its top and the bottom end of the mounting shell 2 can always be kept in contact with each other, which can effectively improve the stability of the fixed position of the mounting shell 2.
