Usual applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and digital line shafting. Industries offered include Material Managing, 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 in addition to 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 dependable transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides an outstanding transmission quality and allows for precise positioning tasks.

They can be purchased in nine sizes with decrease ratios from 3:1 to 600:1 and output 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 elements with no need for a coupling. For high precision applications, backlash amounts down to 1 arc-minute can be found. Right-angle and input shaft versions of the reducers are also offered.

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

Fewer components also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads regularly use right-position gears to reduce the distance a reducer extends beyond a machine. Right-angle gears, however, require an additional set of bevel gears to make the change. These gears boost the solution’s size, price, complexity, and total backlash since another system is placed between the load and the motor. Use of beveled gears defeats the benefit of a planetary gearhead completely.
