Normal applications for these reducers include 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 selection of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes as well as various combinations thereof. All common servo motors can be very easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and reliable transmission through their unique design. All ring gears, world gears and sunlight pinions are case – hardened and ground. This provides 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 result torque capacities up to 16,227 lb.ft. The output can be provided with a good shaft or ISO 9409-1 flange, for installation to rotary or indexing tables, pinion gears, pulleys or other drive components 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 offered.

Some planetary-geared servo-motors offer additional options. For example, planetary gearbox for servo motor oil-circulation lubrication and cooling lets models operate continuously 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 styles, alternative components and coatings, custom shafts, nonstandard engine voltages such as for example 24 or 48 Vdc, special feedback products, 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 electric motor technology, providing restricted integration of the motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or personalized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and quiet running.

Fewer components also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads often use right-angle 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 change. These gears boost the solution’s size, price, complexity, and total backlash since another mechanism is placed between your load and the engine. Usage of beveled gears defeats the advantage of a planetary gearhead entirely.
