 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.

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.

System Specifications: |
 Our
ZTR & ZR Rack & Pinion Drive Systems utilize our
Precision Planetary Reducers with an
ISO 9409-1 output flange to provide a rigid support for a hardened
& ground helical pinion. This provides tight integration of the
driven load while allowing replacement of the pinion if needed. These
systems are available in seven sizes with 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
,
