How a shaft-mounted reducer works

A shaft-mounted reducer fits directly onto the shaft of the driven machine, so no coupling or base plate is needed. The motor drives the reducer through a belt, and a torque arm anchors the reducer and keeps the belts at the correct tension. Changing the motor and reducer pulleys gives a range of output speeds.

Construction and options

• Grey cast-iron housing with reinforcing and cooling ribs
• Case-hardened helical steel gears with a controlled or ground tooth profile
• Ball and/or taper-roller bearings

• Backstop available on request for all sizes, plus special executions and accessories

Gear capacity is calculated to ISO 6336, DIN 3990 and AGMA 2001-B88. Efficiency is about 0.98 for single-stage and 0.96 for double-stage units.
