Normal applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete selection of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes and also various combinations thereof. All common servo motors could be easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and reliable transmission through their particular design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides a superb transmission quality and permits precise positioning tasks.

They can be purchased in nine sizes with planetary gearbox for servo motor decrease ratios from 3:1 to 600:1 and result torque capacities up to 16,227 lb.ft. The output could be provided with a solid shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive components with no need for a coupling. For high precision applications, backlash amounts right down to 1 arc-minute are available. Right-angle and input shaft versions of these reducers are also obtainable.

Some planetary-geared servo-motors offer additional options. For instance, oil-movement lubrication and cooling lets products operate continually at up to 3 x the nominal torque and power rating. Oil-cooling also continues the actuator great in high-temperature environments. Other options include explosionproof styles, alternative materials and coatings, custom shafts, nonstandard motor voltages such as 24 or 48 Vdc, special feedback products, and special electric connectors to operate with most amplifiers.
This standard range of Precision Planetary Reducers are perfect for use in applications that demand powerful, precise positioning and repeatability. They were specifically developed for make use of with state-of-the-art servo motor technology, providing restricted integration of the electric motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or customized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.

Fewer parts also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads often use right-position gears to reduce the space a reducer extends beyond a machine. Right-angle gears, however, require yet another group of bevel gears to help make the turn. These gears increase the solution’s size, cost, complexity, and total backlash since another system is placed between the load and the engine. Use of beveled gears defeats the benefit of a planetary gearhead entirely.
