ATLANTA Drive Systems, Inc., the World Leader in Rack & Pinion Drive Technologies, offers a wide 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, 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.

Eliminating the system backlash preserves accurate axis positioning during the transition period between acceleration/steady state and deceleration, when the rack & pinion flank contact and load reverses direction.

Even high-precision rack & pinions with minimum backlash cannot meet the positioning requirements of ultra-accurate CNC machine tools. For these requirements, a preloaded rack & pinion drive is needed.

The DRP+,KRP+ reducers, through mechanical or electrial pre-load, provide a 0-backlash rack and pinion drive.

Accurate axis positioning is thus preserved - and is maintained even during the transition period between acceleration/steady state and deceleration, when the rack & pinion flank contact and load reverses direction.

Preloaded systems consist of a rack, two pinions, and a reducer/motor drive system.

Additional Information

ATLANTA Drive Systems is pleased to announce a new range of ISO 9409-1 flanged pinions, which have compact designs to reduce the amount of drive torque required. Traditionally, flanged pinions have large pitch diameters which increase the amount of torque on the reducer they mount to.

With this new TR Pinion range, the pinion pitch diameters are significantly reduced, reducing the drive torque required and in turn allows for use of a smaller reducer.

Custom racks & pinions are available in many different shapes, sizes, and materials. Our full service tool and die facility enables us to produce racks and gears in configurations that in some cases allow several parts to be combined into one. Call, fax, or e-mail a sketch and Rack & Pinion will work with you to accommodate your needs.
