Kinematics slew drives are powered with hourglass worm technology to
give the maximum survivability load-holding capability as well as
increased efficiency and accuracy. Unlike standard worms which touch
only 1 tooth, our hourglass worm engages 5-11 teeth on the pitch line of
the ring gear from the hourglass thread. This increased tooth
engagement gives the gearbox enormous strength and power.
We manufacture a wide variety of model sizes, performance ranges and
mounting characteristics. We currently make 9 base model sizes from 75mm
to 800mm in diameter. The performance load characteristics range from
6kNm to 220kNm of holding torque, 200Nm to 63kNm of output torque, 500Nm
to 271kNm of overturning moment load capacity, and gearbox reduction
ratios of 30:1 up to 156,600:1. The mounting can be done horizontally,
vertically or a combination of multiple axes.
