Apex Dynamics has been selected as the supplier of a key component by rotary measurement specialist Rotary Precision Instruments (RPI) UK because of the fast delivery, low backlash, low noise and good value offered by its AF series precision planetary gearboxes.

The world’s largest manufacturer of rotary devices, RPI UK was looking for a new supplier when lead times rose sharply after the Covid-19 pandemic and the company found it more difficult to source parts. After seeking a reliable supplier that could meet its very specific requirements for high-accuracy measurements and angular positioning, the company turned to Apex Dynamics, which provides delivery times of 2-3 weeks.

In this case, the gearbox had to fit into the existing design of a rotary table for CMMs. The AF series gearbox is now used in RPI UK’s LabStandard and QuadDualPurpose assemblies. Itmounts to a motor via a pulley arrangement with a belt that drives a worm and wheel arrangement.

Each Apex AF series gearbox has 100% optimised helical gearing, low backlash and easy mounting, reports the company. High precision taper roller bearings equip the gearboxes to handle high axial and radial loads and output torque ranges from 14 to 2000 Nm.

RPI UK technical manager Adrian Blake says: “High levels of accuracy are key to the success of our application-specific products. As a key component of our CMM rotary table, the low backlash provided by the AF series gearbox means that it positions correctly, an essential feature for our machines as it forms part of the drive assembly.All the gearboxes we’ve purchased are running smoothly and have met our calibration standards.”
