Medium-Precision Rack & Pinion Drive Systems


These systems utilize our our precision Planetary and Servo-Worm Reducers, to rigidly support and drive a hardened & ground pinion.  The rack used in these systems is Quenched & Tempered, which has a quality level of DIN 8 (~AGMA 10) and through-hardened teeth.

These drives are perfect for a wide range of applications, including axis drives requiring precise positioning & repeatability, traveling gantries & columns, pick & place robots, CNC routers and material handling systems.  Medium loads and duty cycles can be easily handled with this drives.

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.

Systems Precision:

The system precision, including the pitch error and backlash, can be found below:

System Precision Level: Rack Type: Rack Quality Level: Rack Pitch Error: Rack & Pinion Minimum Backlash: *
Medium Quenched & Tempered DIN 8
(~AGMA 10)		 < 0.100 mm
per meter		 0.04 mm

* The rack and pinion backlash depends on the alignment of the rack to the linear guides.

 

Right-Angle System Specifications:

Our right-angle systems utilize our High-Torque (HT), High-Performance (HP) and Economy (E) Servo-Worm Reducers, which have backlash levels down to one arc-minute, to support and drive a hardened & ground pinion shaft.  These reducers are available in six sizes and have ratios from 4.75:1 to 52:1 (higher ratios available with planetary-worm reducers).  These reducers have options for keyed, compression or flanged outputs, which rigidly support our pinion.

The maximum drive force that each system can handle (with safety factor 1.0) is listed below; this should be compared to the application peak force, which can be calculated here, or by filling out our Application Sheet.

In-Line System Specifications:

These in-line systems utilize our precision Planetary Reducers, which have an ISO 9409-1 output flange which provide a rigid support to a hardened & ground helical pinion.  The reducers have backlash levels down to one arc-minute and ratios from 4:1 to 100:1.

The maximum drive force that each system can handle (with safety factor 1.0) is listed below; this should be compared to the application peak force, which can be calculated here, or by filling out our Application Sheet.
