[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 8 As shown, an embodiment of the present utility model proposes a reduction mechanism housing, including a left housing 1 and a right housing 5. The left housing 1 and the right housing 5 are in an integrated shape. A No. 1 meshing groove 4 is provided at the internal front end of the left housing 1, and a No. 2 meshing groove 6 is provided at the internal upper end of the right housing 5. The No. 1 meshing groove 4 and the No. 2 meshing groove 6 are through-connected, and an axial hole 8 is penetrated at the internal rear end of the No. 1 meshing groove 4. An extension frame 2 is installed on the side of the left housing 1 away from the right housing 5, a No. 1 connecting frame 3 is installed on the upper end of the left housing 1, and a No. 2 connecting frame 7 is respectively installed on the upper and lower ends of the right housing 5 away from the left housing 1. A plurality of threaded holes are provided on the front surface of the left housing 1 and the upper end of the right housing 5.

[0024] like Figures 4 to 8 As shown, in another embodiment of the present invention, a plurality of heat sinks 9 are installed at the upper and lower ends of the outer side of the left shell body 1, and an air guide hole 10 is provided between the No. 1 connecting frame 3 and the No. 1 engaging groove 4. The air guide hole 10 is located in the channel between the No. 1 connecting frame 3 and the left shell body 1 and is set to be curved, and a filter is installed at the upper end of the inner part of the air guide hole 10, and an oil filling pipe 11 is installed on the lower side of the inner rear end of the No. 1 engaging groove 4, and a sealing cover 12 is installed at the rear end of the oil filling pipe 11 through a thread, and a filter is installed inside the oil filling pipe 11, and a sealing plug 13 is installed in the middle of the inner part of the sealing cover 12. The sealing plug 13 is snap-fitted and installed inside the oil filling pipe 11, and a sealing ring 14 is installed between the sealing cover 12 and the oil filling pipe 11.

[0025] The user removes the sealing cap 12 through the threaded part to allow the waste oil inside the left housing 1 to be discharged along the oil filling pipe 11. After the waste oil inside the left housing 1 is discharged, the user can inject new oil through the oil filling pipe 11 without the user having to disassemble the entire housing for oiling. This not only reduces the user's operating difficulty, but also improves the oiling efficiency and avoids the situation where dust and other substances fall into the left housing 1 and the right housing 5 due to disassembly and cause pollution.

[0026] The air guide hole 10 is used to maintain air circulation inside the left housing 1 and the right housing 5, reduce the internal pressure and temperature, maintain air pressure balance, and prevent lubricating oil from leaking through the air guide hole 10 through the curved shape inside.

[0027] The sealing plug 13 and the sealing ring 14 are used to improve the sealing performance between the sealing cover 12 and the oil filling pipe 11 to avoid leakage of lubricating oil;

[0028] The heat sink 9 is used to assist the overall heat dissipation and improve the overall heat dissipation efficiency and heat dissipation effect.

[0029] The working principle of a reduction mechanism housing:

[0030] When in use, the user first removes the sealing cover 12 through the thread to allow the waste oil inside the left shell 1 to be discharged along the oil filling pipe 11. Then, after the waste oil inside the left shell 1 is discharged, the user can inject new oil through the oil filling pipe 11. The user does not need to disassemble the entire body for oiling, which reduces the user's operating difficulty and improves the oiling efficiency. It also avoids the situation where dust and other substances fall into the left shell 1 and the right shell 5 due to disassembly and cause pollution.

[0031] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
