Thomson Micron's UltraTrue CD® gearhead doubles service life in high-speed, continuous-duty applications. "The new gearhead lasts better than twice as long as conventional planetary gearheads when used in continuous applications," says Serge Jean-Charles, Thomson Micron's product supervisor for power transmission products.
UltraTrue CD specifies a 4,500 rpm input speed, and a 98.5% mesh efficiency with an extended life. Istrophic tooth surface treatment reduces friction and scoring probability. The design also features post-heat-treatment flank-finished carburized gears, a tooth profile that reduces sliding contact in the gear mesh, and tooth crowning for even load distribution across the gear's flank, according to Jean-Charles. In addition, a unique venting system reduces internal pressure, and a passive filtration system keeps the lubricant clean. Improvements compared to conventional gearheads include:
A 25,000 hr service life
A 20% backlash reduction over industry standard
Lower startup backlash and lower backlash increase over time
Efficiency improvements ranging from 3% to 6% (at 25% torque)
A reduction of the normal running temperature
An 8 dB reduction in noise
Thomson Micron’s UltraTrue CD uses novel surface treatments that reduce friction and heat generation to effectively double service life in high-speed, continuous-duty servo applications
