Rack and pinion drives eliminate system backlash via split-pinion or dual-pinion arrangement. Positioning accuracy is maintained during acceleration and deceleration as well as for direction of travel reversals. Mechanically preloaded split-pinion drives utilize axial spring to load one pinion half against other. Electrically preloaded dual-pinion drives utilize 2 motors, each driving one pinion loaded against each other via motor controller.
********************
Atlanta Drive Systems, Inc. offers a range of zero-backlash rack & pinion drives that eliminate system backlash by means of a split-pinion and dual-pinion arrangement, providing ultra-precise positioning and repeatability. Positioning accuracy is maintained during acceleration and deceleration, as well as for direction of travel reversals.
The backlash is eliminated by using two pinions - one to drive the axis and the other to engage the opposite tooth flank and take up the backlash. Mechanically preloaded split-pinion drives utilize an axial spring to load one pinion half against the other. Electrically preloaded dual-pinion drives utilize two motors, each driving one pinion, which are loaded against each other by means of a special motor controller.
