AI Technical Summary

Technical Problem

Existing gearbox cooling methods suffer from low heat exchange efficiency, making it difficult to dissipate heat quickly, which leads to gear wear, reduced transmission accuracy, and may even cause malfunctions.

Method used

A heat dissipation duct is set inside the gearbox, and a directional airflow path is formed through the drive component and the transmission connection with the disturbance wheel. The disturbance wheel and heat dissipation fins are used to accelerate heat transfer and enhance heat dissipation efficiency.

Benefits of technology

It significantly improves heat dissipation efficiency, suppresses temperature rise, reduces gear wear risk, improves transmission accuracy and equipment reliability, simplifies structural layout, and reduces equipment weight and energy consumption.

Abstract

This utility model discloses a lightweight gearbox with an integrated heat dissipation duct, comprising two sets of housings connected by bolts. Two sets of heat dissipation channels are provided on each housing, and disturbance wheels are installed within these channels. A drive assembly is also provided within each housing, and the drive assembly is connected to the disturbance wheels in the two sets of heat dissipation channels, thereby agitating the air within the channels and accelerating heat dissipation. The beneficial effects of this utility model are: the two sets of heat dissipation channels on the housing provide a directional and dedicated flow path for the heat dissipation airflow, effectively avoiding airflow turbulence, while expanding the heat exchange area between the housing and the air, providing structural support for subsequent enhanced heat dissipation; moreover, the drive assembly and the disturbance wheels in the two sets of heat dissipation channels form a transmission relationship, which can forcibly agitate the air within the channels, significantly improving the airflow speed and exchange frequency within the channels.
