Servo gearhead holds up to continuous duty

Thomson Micron's UltraTrue CD^(R) 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
