AI Technical Summary
Technical Problem
Traditional reduction gearboxes generate high pressure due to heat during high-speed, heavy-load operation, leading to seal failure and lubricant leakage, which affects operational stability and safety.
Method used
A reduction gearbox including elastic seals and protective structures was designed. Through the combination of connecting pipes and flanges, high-pressure gas can be discharged and pressure balanced to prevent seal failure.
Benefits of technology
It effectively maintains the air pressure balance inside the gearbox, reduces seal failure, and improves operational stability and safety.

Abstract
The application provides a reduction gear box, comprising a gear box structure and a protection structure arranged on the gear box structure, the gear box structure comprising an upper box body, the protection structure comprising a connecting piece arranged on the upper box body, the connecting piece being connected with a bottom shell, the bottom shell being communicated with a third connecting pipe, the bottom shell being provided with a second connecting pipe, an elastic sealing piece being arranged between the bottom shell and the second connecting pipe, and the elastic sealing piece being used for sealing the second connecting pipe. Through the protection structure, the excess pressure generated in the operation process of the gear box structure can be released to the external environment in time, the pressure in the gear box structure is maintained at a reasonable level close to the atmospheric pressure, the sealing failure of the connecting surface of the gear box structure caused by high pressure is reduced, and the operation stability and safety are improved.
