Ultra-Precise Positioning Achieved with Zero-Backlash Rack & Pinions
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.
These drives are perfect for a wide range of applications, including traveling gantries & columns, milling machines, and material feel axis drives. Industries served include Material Handling, Automation, Aerospace, Woodworking, Machine Tool and Robotics.
Typical delivery time for these standard components is only 2 to 3 weeks - ideal for OEM's requiring just-in-time delivery schedules. Special and/or modified designs are always possible.
