XBF-II Differential Gear | XBJQR Harmonic Drive

Specially designed for phase adjusting and differential gear applications, these component sets and gear units are ideal for adjusting registration or phasing of shafts. High reduction ratios allow precise adjustments with minimal torque.

XBF-II series is a pancake-style component set phasing differential.

The XBF series is an extremely compact differential unit that allows you to fine-tune the phase and timing during operation. The XBFcomponent set consists of four parts: the wave generator, flexspline, circular spline and dynamic spline. This unit must be integrated into the machine design.

Key Features:

Pancake component set
Ultra compact differential unit
Backlash is very small and unit requires no assembly adjustment
Very large reduction ratios between the adjusting shaft and the output, it allows precision position adjustment and requires little torque for adjusting the shaft
Easily installed into OEM equipment
Consists of only four parts and is mounted coaxially

Rotational direction and reduction ratio

The section describes how to use the unit as differential unit.
(R indicates the reduction ratio value in the ratings table.)
