Shaft attach reducers are enclosed helical gear reducers with a hollow result. They are mounted directly on the insight shaft of the driven machine and are backed by the shaft and torque arm set up or motor mount framework. This eliminates the need for additional elements 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 quickness shaft
• an optional backstop
The Browning® shaft attach reducer, generally known as the Browning SMTP, is a cost-effective method of driving machinery. The shaft install design eliminates the necessity 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 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 decrease stage. Typical industries for the Browning SMTP are aggregate, baggage managing, grain and wastewater treatment.
