Types of Speed Reducers
The Speed Reducer eliminates unnecessary transmission equipment, thus providing compact drives, and assures positive performance. It is made with speed reduction ratios up to 4,000 to 1 and with right angle (vertical or horizontal), or parallel shafts for either light or heavy duty. The information which follows gives applications and other pertinent data on the various general types. Right Angle
Thickener Drive Speed Reducer
The Integral Lift Vertical Worm Gear-Box Speed Reducer is used on Center and Side Air-lift Agitators, Hydroclassifiers, and on thickeners in many mills and industrial plants where it is necessary to have a simple, compact, totally – enclosed, self-lubricated reduction unit. This unit is widely used to step down speeds of high-speed motors to the slow speed required by many ore
