Zero-backlash speed reducers

02 March 2009

A new range of zero-backlash speed reducers is now available in the UK. This news comes as a result of the recent appointment of Precision Motion (COFIL) as agent for Japanese manufacturer Kamo Seiko Corporation.

Available in both co-axial and right-angle configurations, these patented speed reducers utilise precision ground steel balls as the transmission medium. The benefits, when compared with the more conventional planetary or cycloidal gearboxes, include: no clearances, therefore zero backlash; rolling contact, thus considerably reducing noise; high efficiency; high torque capacity; and excellent accuracy.

There is a huge choice of input/output options to suit all applications, including a version to allow direct fitting of NEMA 11 to 34 frame motors. In addition, the housing is designed to facilitate easy addition of custom made flanges for special applications. Reduction ratio’s are available from 5:1 to 1600:1, with rated output torque capacity ranging from 1.6Nm to 98Nm.
