Ultra-Flat, Zero-Backlash Gear



Harmonic Drive LLC offers its ultra-flat, zero-backlash CSF-2UP gear unit, part of its CSF mini-series product line.

These high-torque, zero-backlash gear units have an ultra-flat configuration and feature a large cross-roller bearing with high-moment stiffness. Complete with a housing and precision output bearing, Harmonic Drive gear units are lightweight and extremely compact. The CSF-2UP gear heads are suited for robots or manipulators requiring an ultra-compact solution.

Harmonic Drive gear units are comprised of a zero-backlash gear integrated with a housing and precision output bearing. These models are lightweight and flat. Utilizing a large cross-roller bearing at the output flange allows direct mounting of the load without the need for any additional support, enabling compact robot designs. "These bearings have excellent axial and radial run-out characteristics and provide high load capacity as well as high-moment stiffness to achieve precise, repeatable positioning of the robot arm," said a company spokesperson.

Gear Ratios of 30:1, 50:1 and 100:1 are available in each size, offering the machine designer a wide selection of speed and torque specifications. Motor mounting adapters are also available to match the designer's choice of motor.

The CSF-2UP mini gears are designed to be reliable and maintain zero backlash for the life of the gear.
