Shaft install reducers are enclosed helical gear reducers with a hollow output. They are mounted on the input shaft of the powered machine and are supported by the shaft and torque arm arrangement or motor mount framework. This eliminates the necessity for additional components to transmit torque from the reducer to the gear. The parts of a shaft attach reducer include:

• rotating bushing ring
• TorqTaper® bushing
• torque arm bracket
• torque arm rod and turnbuckle
• foot bracket
• input or high speed shaft
• an optional backstop

The Browning® shaft install reducer, generally known as the Browning SMTP, is a cost-effective approach to driving machinery. The shaft attach design eliminates the necessity for support structures that are necessary in conventional foot installed 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 machine to be mounted at 360 degrees around the shaft and at the end of the conveyor. Additionally, the reducer is quite efficient at approximately 98.5% efficiency per reduction stage. Typical industries for the Browning SMTP are aggregate, baggage handling, grain and wastewater treatment.
