Product Overview
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.
Frequently Asked Questions
What are the main advantages of SHG/SHF harmonic gearboxes?
They offer high torque density, zero backlash, lifelong precision, and high tilting capacity due to integrated cross roller bearings, making them ideal for space-saving designs.
What is the difference between SHG/SHF-2UH and 2SH models?
The 2UH model is a fully sealed unit with a large hollow shaft, while the 2SH is a shorter and more lightweight version designed for maximum flexibility in design integration.
Are these harmonic drives suitable for robotics?
Yes, they are specifically designed for highly dynamic applications such as robot axes, where positioning accuracy and compact size are critical.
What reduction ratios are available for these series?
The SHG and SHF series provide various ratios including 30:1, 50:1, 80:1, 100:1, 120:1, and 160:1 to suit different torque requirements.
Does the zero backlash feature last for the life of the gear?
Yes, harmonic drives are engineered to maintain lifelong precision and zero backlash under normal operating conditions.
Can I pass cables through the gearbox?
Yes, the hollow shaft designs (especially in 2UH and 2SH series) allow supply lines, cables, or shafts to be fed directly through the center of the unit.
