Straight-toothed sprocket wheel ZTRS series

Dual-Pinion Electrical Preload Another method to remove the backlash at the rack & pinion is to use two motor/reducer assemblies with dual pinions operating on the same rack in a master/slave setup. One pinion drives the axis (the "master") while the second pinion is "preloaded" to remove the backlash (the "slave"). The preload is created electronically with a special motor controller; these systems can also be set up to drive together during cycle times when backlash is not critical. Dual-pinion gearboxes using only one motor are also possible, please consult the factory. Our Automatic Lubrication Systems are highly recommended for use with these drives, providing continuous grease lubrication to the rack & pinion tooth flanks to preserve the quality and lifetime of the gearing. These drives are perfect for precise positioning applications, such as traveling gantries and columns, milling machines, CNC routers and material feel axis drives. Two reducers/motors can also be used to eliminate the axis backlash by electrical preload.
