New lighter, super flat gear component set
Available in five sizes from 20 to 50, Harmonic Drive's new CSD design is smaller, flatter, lighter and more efficient than its previous component sets
For today's engineers who are forever looking for ways of making devices smaller yet better, Harmonic Drive has developed a precision gear component set that will help them in their task.
The new CSD range, available from Heason Technologies Group, is smaller, flatter, lighter and more efficient than its previous component sets and will enable engineers to design extremely compact dynamic devices.
Some ten years ago Harmonic Drive introduced the HFUC range that was 40% shorter and 20% lighter than the company's preceding HDUC gear component sets.
Now, the new super flat CSD component sets have reduced the length of the compact HFUC by nearly 50% with something in excess of 40% saving in weight.
The CSD covers a repeated peak torque range from 39 to 823Nm with reduction ratios of 50:1, 100:1 and 160:1.
Accuracy exceeds 30 seconds of arc and repeatability is better than 5 seconds of arc whilst torsional stiffness is improved by 30%.
It is available in five sizes from 20 to 50.
According to Heason, as well as being physically small, tests have shown the CSD to be very robust.
This makes it ideal for flat precision drives and indexing tables, plus applications for the aerospace industry.
Like other Harmonic Drive gear sets, the CSD comprises three basic components: Wave Generator, Flexspline and Circular Spline.
To achieve the reduced length the company's engineers cut the Flexspline and Wave generator bearing dimensions to shrink overall length to a third of the original HDUC.
