Regular applications for these reducers include planetary gearbox for servo motor precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the whole range of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes in addition to various combinations thereof. All common servo motors can be easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes guarantee high stiffness and reliable transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This gives an outstanding transmission quality and permits precise positioning tasks.

They can be purchased in nine sizes with reduction ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output could be provided with a good shaft or ISO 9409-1 flange, for installation to rotary or indexing tables, pinion gears, pulleys or other drive elements with no need for a coupling. For high precision applications, backlash amounts down to 1 arc-minute are available. Right-angle and insight shaft versions of the reducers are also available.

Some planetary-geared servo-motors offer additional options. For example, oil-stream lubrication and cooling lets units operate constantly at up to three times the nominal torque and power ranking. Oil-cooling also helps to keep the actuator cool in high-temperature environments. Additional options include explosionproof designs, alternative components and coatings, custom shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback devices, and special electrical connectors to operate with most amplifiers.
This standard selection of Precision Planetary Reducers are ideal for use in applications that demand powerful, precise positioning and repeatability. These were specifically developed for make use of with state-of-the-art servo engine technology, providing tight integration of the engine to the unit. Design features include installation any servo motors (IEC, NEMA, or customized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and calm running.

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