Helical planetary gearhead has the torque

The Stealth Advanced line of planetary gearheads from Bayside Motion Group, port Washington, N.Y.,have the high torque and low backlash needed for demanding servo applications.

Backlash is as low asthree arcminutes, and gearheads have 30% more torque than standard planetaries. They're also quiet,operating at 97% efficiency while generating less than 68 dB of noise with input speeds as high as6,000 rpm. They are available in a PS (Inline) and RS (Right Angle) model. They are available inseveral frame sizes and gear ratios. Both models have 40% more stiffness than comparable planetariesin the same frame size. Helical gearing increases gear-tooth engagement, thus ensuring quiet, smoothoperation. The gears also carry higher loads than spur gears. Contributing to the quiet operation areHelicrown gear teeth, a patented tooth design. It eliminates metal at the tooth's entry and exitpoints, without sacrificing gear strength. Gear teeth are also put through a plasma nitriding process.This results in a wear-resistant gear tooth that withstands heavy shocks, ensuring high accuracy forthe life of the gearhead.
