Harmonic Drive Mini Gearheads: HDI Series Infinit-Indexer® Phase Adjusters

These gearheads can be easily adapted to any OEM servo motor. Harmonic Drive® gear products offer zero-backlash with gear ratios from 30:1 to 160:1. Precision planetary gearing products are available with gear ratios from 3:1 to 45:1 with backlash maintained below 1 arc-min. High capacity output bearings are utilized for robust and accurate support of loads. Other benefits include flange and shaft output configurations, hollow shaft designs, and sizes ranging from 0.625 inches to over 10 inches in diameter.

HDI Series Mini Gearheads

HDI's are shaft mounted gear reducers. They provide hand adjustable, precise, static phase adjustment. On rotating shafts the HDI functions as rigid shaft coupling. Phase adjustment is accomplished when the drive system is stopped. Adjustments are made by hand in either direction by adjusting the knurled outer ring producing infinitely variable relative rotation of the hubs through a 100:1 reduction ratio. With the "D" hub fixed, rotation of the "S" hub is opposite to the direction of nut rotation. With the "S" hub fixed, rotation at the "D" hub is in the same direction as nut rotation.

Infinit Indexers are available in 6 sizes and have torque ratings form 500-20,000 inch pounds. There are two ways to purchase HDI phase adjusters; from our stocking program or by special order from a customer request.
