Normal applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and electronic line shafting. Industries offered include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo planetary gearbox for servo motor gearboxes PT complete the complete selection of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes in addition to various combinations thereof. All common servo motors can be easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and reliable transmission through their unique design. All band gears, planet gears and sunlight pinions are case – hardened and ground. This gives a superb 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 solid shaft or ISO 9409-1 flange, for installation to rotary or indexing tables, pinion gears, pulleys or other drive elements without the need for a coupling. For high precision applications, backlash amounts down to 1 arc-minute can be found. Right-angle and insight shaft versions of the reducers are also offered.
Some planetary-geared servo-motors offer additional options. For example, oil-flow lubrication and cooling lets systems operate continually at up to three times the nominal torque and power rating. Oil-cooling also will keep the actuator cool in high-temperature environments. Other options include explosionproof styles, alternative materials and coatings, custom shafts, nonstandard engine voltages such as for example 24 or 48 Vdc, special feedback gadgets, and special electrical connectors to use with most amplifiers.
This standard selection 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 motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless 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-angle gears, however, require an additional set of bevel gears to help make the turn. These gears increase the solution’s size, price, complexity, and total backlash since another mechanism is placed between the load and the electric motor. Usage of beveled gears defeats the benefit of a planetary gearhead entirely.
