AI Technical Summary

Technical Problem

In the fan drive unit of the cooling tower, the belt drive mechanism occupies a large space, resulting in an excessively large overall space occupied by the power unit and low transmission efficiency.

Method used

A single-stage planetary gear reducer is used as the power transmission mechanism, which includes a motor, reducer, planetary gear mechanism and fan connection. The layout of the planetary gear mechanism makes the power transmission more concentrated, the structure is compact, the number of parts is reduced and the transmission efficiency is increased.

Benefits of technology

It reduces the size of the power unit, improves transmission efficiency, saves electricity and electricity costs, extends the service life of transmission components, and reduces maintenance requirements.
