Gear reducers

A gear reducer is a gearbox that brings motor speed down and, in exchange, multiplies torque at the output shaft. It is how a fast-spinning electric motor gets matched to the low speed and heavy load of conveyors, mixers, agitators, elevators, pumps and crushers.

Part numbers combine the series and the housing size. In the Quantis line, Quantis ILH 38, Quantis ILH 68 and Quantis ILH 108 are one series in ascending sizes, and a larger size means more torque capacity. When you replace a reducer, have the nameplate at hand with series, size and ratio.

Selection starts with output torque and motor power, multiplied by a service factor for the load type (uniform, moderate shock or heavy shock) and the hours of operation per day. Next come the ratio, input speed, mounting style (foot, flange or shaft mount), output shaft diameter and any overhung load it will carry, for example from a chain or sheave. Environment (dust, humidity, temperature) and the lubrication method also count.

We quote DODGE gear reducers. Send the full part number or a photo of the nameplate by WhatsApp. For new equipment, include motor power, input and output RPM and duty type, and we will quote it shortly. We can also quote the couplings, sheaves, chains and belts to complete the drive.
