SMSR - Shaft Mounted Speed Reducer

Shaft mount reducers are enclosed helical gear reducers with a hollow output. They are mounted directly on the input shaft of the driven machine and are supported by the shaft and torque arm arrangement or motor mount frame. This eliminates the need for additional components to transmit torque from the reducer to the equipment.
The Browning® shaft mount reducer, also referred to as the SMSR, is a cost-effective method of driving machinery. The shaft mount design eliminates the need for support structures that are required in conventional foot mounted reducer assemblies. It also eliminates the need for chain, sprockets, couplings and bedplates. In addition, the design minimizes alignment problems.
The compact design of the shaft mounted reducer helps save space. It also allows the unit to be mounted at 360 degrees around the shaft and at the end of the conveyor. Additionally, the reducer is very efficient at approximately 98.5% efficiency per reduction stage. Typical industries for the SMSR are aggregate, baggage handling, grain and wastewater treatment.
