Description

Technical Field

[0001] This utility model relates to the field of double planetary gear technology, specifically a double planetary gear with good load-bearing capacity. Background Technology

[0002] Planetary gears, also known as planetary propellers, are gear systems where, in addition to rotating around their own axis like fixed-axis gears, their axes also rotate around the axes of other gears along with the planet carrier. Rotation around their own axis is called "rotation," and rotation around the axes of other gears is called "revolution," much like the planets in our solar system, hence the name. Double planetary gear sets are part of a planetary gear system, primarily serving a transmission function. Existing double planetary gear sets exhibit wear over prolonged use, with the wear patterns of the large and small gears differing. Since existing double planetary gear sets are integrated units, they can only be replaced as a whole, resulting in waste. Utility Model Content

[0003] The purpose of this invention is to provide a double planetary gear with good load-bearing capacity to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a double planetary gear with good load-bearing capacity, comprising:

[0005] A double planetary gear body includes a large gear body and a small gear body, which are integrally formed. Both the large and small gear bodies are provided with matching coupling rings. Each coupling ring has multiple annularly equidistantly distributed gear teeth. The inner wall of each coupling ring has multiple annularly equidistantly distributed limiting blocks. Both the large and small gear bodies have mounting grooves on their side walls, each mounting groove having multiple annularly equidistantly distributed insertion grooves. The limiting blocks are adapted to the insertion grooves. Each mounting groove has a locking ring and multiple annularly equidistantly distributed threaded holes. The locking ring has multiple annularly equidistantly distributed through holes, each through hole containing a fastening bolt threaded into the threaded hole.

[0006] Preferably, the large gear body and the small gear body are provided with shaft holes.

[0007] Preferably, the mounting groove is provided with a plurality of annularly distributed positioning grooves, and a plurality of annularly distributed positioning posts are fixedly welded to the inner wall of the locking ring, the positioning posts being adapted to the positioning grooves.

[0008] Preferably, the sleeve ring is integrally formed with the wheel teeth and the limiting block.

[0009] Preferably, the gear teeth are made of high-carbon steel.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The two sets of gear teeth of this utility model are respectively sleeved on the large gear body and the small gear body through corresponding sleeve rings. The sleeve rings are limited and fixed by the insertion of the set limit blocks and the insertion slots. The set locking rings lock and fix multiple limit blocks, so that after the gear teeth wear out after long-term use, only the gear teeth need to be replaced, without the need to scrap and replace the entire double planetary gear. Moreover, the gear teeth on the large gear body and the small gear body can be replaced independently, avoiding the problem of scrapping the entire double planetary gear due to the damage of one gear tooth, reducing waste and saving costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a double planetary gear with good load-bearing capacity, comprising:

[0019] The double planetary gear body 1 includes a large gear body 2 and a small gear body 3, which are integrally formed. Both the large gear body 2 and the small gear body 3 are provided with matching sleeve rings 4. Each sleeve ring 4 has multiple annularly equidistantly distributed gear teeth 5. The inner wall of the sleeve ring 4 has multiple annularly equidistantly distributed limiting blocks 6. Both the large gear body 2 and the small gear body 3 have mounting grooves 7 on their side walls. Each mounting groove 7 has multiple annularly equidistantly distributed insertion grooves 8, and the limiting blocks 6 are adapted to the insertion grooves 8. Each mounting groove 7 has a locking ring 9, and each mounting groove 7 has multiple annularly equidistantly distributed threaded holes 10. Each locking ring 9 has multiple annularly equidistantly distributed through holes 11, and each through hole 11 contains a fastening bolt 12 threadedly connected to one of the threaded holes 10.

[0020] The large gear body 2 and the small gear body 3 are provided with shaft holes 13, which are used to install double planetary gears.

[0021] The mounting groove 7 is provided with a plurality of annularly distributed positioning grooves 14. The inner wall of the locking ring 9 is fixedly welded with a plurality of annularly distributed positioning posts 15. The positioning posts 15 are adapted to the positioning grooves 14. Through the insertion and cooperation of the positioning posts 15 and the positioning grooves 14, the locking ring 9 can be positioned during installation, and the through hole 11 can be aligned with the screw hole 10.

[0022] The sleeve ring 4 is integrally formed with the gear tooth 5 and the limiting block 6.

[0023] The gear teeth 5 are made of high-carbon steel, which has the characteristics of high strength, high toughness and wear resistance, thus improving the load-bearing capacity of the double planetary gears.

[0024] Working principle: The two sets of gear teeth 5 of this utility model are respectively sleeved on the large gear body 2 and the small gear body 3 through corresponding sleeve rings 4. The sleeve rings 4 are limited and fixed by the insertion cooperation between the set limit block 6 and the insertion groove 8, and the set locking rings 9 lock and fix multiple limit blocks 6. This allows only the gear teeth 5 to be replaced after long-term use and wear, without the need to scrap and replace the entire double planetary gear. Moreover, the gear teeth 5 on the large gear body 2 and the small gear body 3 can be replaced independently, avoiding the problem of scrapping the entire double planetary gear due to the damage of one gear tooth 5, reducing waste and saving costs.
