Worm Gear Reducers

A worm gear reducer, also known as a worm gearbox, is one type of right-angle drive. It is used to reduce rotational speed and increase torque in a mechanical system.

It consists of a worm (a threaded cylindrical gear) and a worm gear (or worm wheel). The worm has a spiral thread that meshes with the teeth of the worm gear, resulting in high reduction ratios in compact housing.


Standard Worm Gear Reducer Features

•    Compact and space-saving design
•    Right angle drive
•    Can transmit high torque loads
•    Non-back driving characteristic (ratio above 20:1)
•    High gear reduction ratios available
•    Worm gear efficiency is 50-90% based on ratios of 3.5:1 to 100:1

Right Angle Gearboxes / Right Angle Drives

Right-angle gearboxes, also known as right-angle drives, are mechanical devices used to transmit power and change the direction of rotational motion by 90-degrees. Designed to efficiently transfer torque from an input shaft (typically parallel to the motor or power source) to an output shaft (perpendicular to the input shaft).
A right-angle gearbox can use bevel gears, helical gears, or even worm gears. Each gear set has its own advantages. A straight bevel, spiral bevel or Zerol gear provides a 90-degree input/output on the same plane. Whereas helical and worm gearing, the input shaft is on one plane and the 90-degree output shaft is on a second plane.


Standard Right Angle Gearboxes Features

•    Load capacity of gearboxes are unaffected by direction and rotation
•    High efficiency power transmission, minimum power loss
•    Bevel and helical gear efficiency is 93-98%
•    1:1 and 2:1 ratios
