Speed reducers, often called gear reducers, serve primarily two purposes. One, take the toque created by the power source (input) and multiply it. Second, much as the name implies, reduce the speed of the input so the output is correct. A gear reducer is located between the motor and machinery being used to control the speed with which power is transmitted. So, how does a speed reducer increase the torque while decreasing speed? Gear teeth. The output gear of a speed reducer has more teeth than the input gear. So, while the output gear might rotate more slowly, reducing the speed input, the torque is increased. Simply put, take input power source and increase torque while decreasing speed.

Boston Gear Reducer F718-20-B5-G is a Right Angle Worm Gear Speed Reducer – Single Reduction, 20:1 Ratio, 1.75 in Center Distance, C-Face Quill, 0.6250 in Input Size, Left Hand Output, 56C Frame. Integral input worm and shaft design made from high-strength, case-hardened alloy steel. Multi-position mounting flexibility of the 700 Series speed reducers allows for installation in almost any position. Large oil reservoir provides highly efficient heat dissipation and lubrication for longer operating life. Reducer sizes 710 through 726 have pre-lubricated ball bearings; 732 through 760 have tapered roller bearings.
