Reliability

Kinematics slewing drives are designed and tested to guarantee a 30-year field life. All aspects of engineering control are based on creating a low-cost, reliable solution. Using the same methods and procedures that earned us our ISO 9001, CE, REACH, and TUV certifications, we qualify all the raw materials, components and final assemblies to meet these standards.

Performance

Kinematics slew drives are powered with patented hourglass worm technology to give maximum survivability load-holding as well as increased efficiency and accuracy. Unlike standard worms which touch only one 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.

Applications

When little to no backlash is needed for an application, the Kinematics ZE slewing drive is ideal. The drive offers as low as 0.01° of backlash. This is ideal for solar trackers, specifically Concentrated Photovoltaics (CPV), solar troughs, and heliostats that need to focus on a single point along with wind turbines and stellite and radar dishes. Various man-lift manufacturers also use the ZE slewing drive when backlash needs to be reduced for safety reasons while still maintaining 360° of rotation.

Specifications

Our base model sizes deliver performance ranges from 3kNm 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. It can be horizontally or vertically mounted.
