These systems
utilize our our precision
Planetary and Servo-Worm Reducers, which have backlash
levels down to one arc-minute, to rigidly support and drive a hardened & ground
pinion. The rack used in these systems is also hardened & ground.
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. Heavy 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.

NEW
HighForce ZTRS Rack & Pinion Drive Systems,
with an
integral output housing and outboard bearing to provide a rigid support to
the output pinion, increasing the linear stiffness of the system by
300%, as well as increasing the power density of the system.
Also, the unique design of the pinion allows for smaller pitch
diameters, which reduces the reducer torque. Because of these
design enhancements, a smaller reducer can typically be used.

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
,

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.
