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

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

The Browning® shaft attach reducer, generally known as the Browning SMTP, is a cost-effective approach to traveling machinery. The shaft mount design eliminates the necessity for support structures that are required in conventional foot mounted reducer assemblies. In addition, it 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 installed 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 decrease stage. Common industries for the Browning SMTP are aggregate, baggage managing, grain and wastewater treatment.
