High-Precision Inline Strain Wave Gearboxes

SureGear strain wave gearboxes offer many advantages over planetary and helical gearboxes. Strain wave (also known as harmonic) gearboxes allow for a higher gear ratio compared to the same sized planetary gearbox. They also generate less heat and noise and are more efficient. These gearboxes are designed to work with SureServo2 motors (up to 1kW medium-inertia) and SureStep stepper motors (or other small NEMA frame motors).

• Stressproof output shaft, high tensile strength, resistant to fatigue and excellent wearability
• Output flange has a precision pilot
• Double-row angular contact bearing provides a precision output with high stiffness, and high radial and axial load capacities
• Flexspline progressively engages with the circular spline with a zero backlash tooth mesh
• Precision shaped circular spline remains stationary and engages with the Flexspline
• Wave generator elliptical ball bearing turns with input motor and causes the rotating elliptical wave form on the Flexspline
• Precision sealed bearing axially fixes the input shaft and wave generator positions
• Quick-connect motor coupling provides reliable and simple connection
• Factory-machined input flange match SureServo2 and SureStep motors
