SHG&SHF series Harmonic Drive Gearbox

Features

SHG&SHF combination harmonic gearboxes are mainly structured by component sets.The cross roller bearing inside the harmonic drive is with high precision and high rigidity,it is used for holding(main bearing) external loading.

SHG&SHF series harmonic gearbox units are available in nine sizes with gear ratios of 50, 80, 100, 120 and 160:1.These harmonic drive gearboxes are ideal for highly dynamic applications, such as in robot axes. This is supported by: enormous torque density, high-tilt output bearing, lifelong precision and zero backlash.

The integrated output bearing with high tilting capacity enables the direct attachment of heavy payloads without the need for further support, ensuring a simple and space-saving design.

SHG/SHF-2UH harmonic drive is fully sealed with a large hollow shaft diameter to feed through supply lines, shafts or cables for further drive systems.Confirmed by many years of successful service,the gears cover a wide torque range and feature a long service life

SHG/SHF-2SO simple gear units are very compact and lightweight. The absence of input and output flanges make maximum flexibility in design integration. And the gears cover a wide torque range and feature a long service life

SHG/SHF-2SH simply units are very short and lightweight. The absence of input and output flanges make maximum flexibility in design integration. The enlarged hollow shaft can be used to feed through supply lines, shafts or cables for further drive systems. Surly,the gears cover a wide torque range and feature a long service life
