Harmonic Drive UK has introduced a gear component for use in robotics and motion control. The shorter, SHD drive targets the trend for smaller, lighter rigs.
A hollow shaft has been incorporated into the centre of the unit with a diameter ranging from 11 to 40mm, allowing the feed-through of cabling, supply lines and other services.
Available in six sizes, from 14-40 with equivalent weights of 0.33 to 3.09kg, the SHD-2SH series units are available with a repeatable peak torque from 12 to 453Nm and reduction ratios of 50, 100 and 160:1. This enhanced power-to-weight ratio is complemented by a shorter Flexspline and heavy duty output bearings.
The SHD-2SH series has been specially adapted to incorporate heavy-duty cross roller output bearings to minimise the overall length. The bearing can withstand both high axial and radial forces as well as high tilting moments.
