Shaft mount reducers are enclosed helical equipment reducers with 
a hollow result. They are mounted directly on the input shaft of the powered machine and are supported by the shaft and torque arm arrangement or motor mount body. This eliminates the necessity for additional components to transmit torque from the reducer to the gear. 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 acceleration 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 need for support structures that are required in conventional foot installed reducer assemblies. It also eliminates the necessity for chain, sprockets, couplings and bedplates. In addition, the look minimizes alignment problems.
The compact design of the shaft mounted reducer helps save space. In addition, it allows the unit 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. Typical industries for the Browning SMTP are aggregate, baggage handling, grain and wastewater treatment.
