MODULAR RACK & PINION SYSTEM RACK & PINION INSTALLATION GUIDELINES The mounting and alignment of rack & pinion drives is critical to the performance and lifetime of the axis. Racks can be mounted in any position. In environments where debris is present (chips, sawdust, etc.) the rack should be mounted with the teeth facing down or covered to minimize contamination. It is recommended that a small right angle “ledge” be provided on the mounting surface to locate the rack on two faces. This makes it easier to accurately mount several pieces of rack in succession. We recommend using the predrilled holes in the rack as a guide for the tapped holes in the mounting surface in order to insure optimum alignment. The following instructions are meant to be general guidelines on how to achieve an accurate mounting of a rack & pinion drive: 1. Mount and align the linear slides (rails) to the axis base. 2. Measure the location of the rail in relation to the rack mounting surface with a dial indicator (see A.). A shoulder should be provided on the mounting surface to locate the back of the rack (see B.). The rack mounting surface tolerance will affect the contact pattern of the drive; the rack shoulder tolerance will affect the backlash of the drive. The more accurate these surfaces are, the better the axis will perform. 3. Attach the first rack segment to the rack mounting surface. Measure the location of the rail in relation to the pitchline of the rack segment with a dial indicator (see diagram C.). To locate the pitchline of the rack, a pin (see table for size) is placed in-between the rack teeth and an over-pin tolerance is measured: Rack Module Module 2.0 Module 3.0 Module 4.0 Module 5.0 Module 6.0 Module 8.0 Module 10.0 Pin Size Ø3.5 mm (Ø0.138”) Ø5.0 mm (Ø0.197”) Ø7.0 mm (Ø0.276”) Ø8.0 mm (Ø0.354”) Ø10.0 mm (Ø0.394”) Ø12.0 mm (Ø0.472”) Ø18.0 mm (Ø0.709”) If the tolerances are found to be high, the rack should be shimmed accordingly and the rack pitchline parallelism should be checked again (step #3).
