ATLANTA Drive Systems Inc. has expanded its range of servo worm reducers, building a high-torque, economy and basic version to go with the existing high-precision reducer. The high-torque model has 150 percent of the torque capacity of ordinary servo-worm reducers, and a backlash level of less than 1 arc-minute. It has a redesigned output for higher bearing capacity, plus an option for ISO 9409 flanged connections. The economy model has the same torque capacity of an ordinary servo-worm reducer, with a less than 6 arc-minutes backlash level. The basic version has 90 percent of an ordinary servo-worm reducer, and a backlash level of less than 12 arc-minutes. There is a range of motor couplings and mounting flanges available for almost any servo motor, and the hollow bore output works well with output shafts, pinion shafts or other drive elements.
