Shaft mounted speed reducers are commonly used in industrial applications where engines or electric motors are used to provide power for low shaft speed applications such as conveyors and hoists. Typically, AC motors run at approximately 1750 RPM, while the shaft speed of a conveyor may be only several revolutions per minute. Many types of speed reducers are available to accomplish this task. Parallel shaft gear reducers, right angle drives, worm gears, V-belt pulleys and others are all found in industrial settings.
For applications requiring high-torque loads and minimal space requirements, a shaft mount reducer is often the best choice. A shaft mount reducer consists of the housing; input and output shafts; and the internal gear sets. A stabilizing link may also be used to prevent rotation of the Falk gear reducer. Another common accessory for a shaft mount gearbox reducer is the anti-roll back adaptor, used to allow rotation in only one direction. This feature will prevent an inclined conveyor from reversing when power is shut off and the conveyor is loaded.
The shaft mount reducer can be installed directly onto the driven shaft of the unit and connected to the driving shaft with a coupling. Shaft mounted bevel speed reducers are also available; these bolt to electric motors and connect with a splined shaft. The bevel gearing allows the output shaft to be at right angles to the motor shaft. This is advantageous in many situations where space or other restrictions require the motor to mount at right angles to the shaft, either horizontally or vertically.
