Torsion spring assembly fights backlash

摘要

San Jose, CA—Until now, designers looking to prevent backlash in light-duty motion-control applications had little to choose from but the traditional ball screw. While that method can be effective, it is primarily aimed at heavy loads, making it a more expensive approach than necessary in many cases. Now, a new line of plastic nut assemblies has been introduced that features a patented device, known as ActiveCAM, that automatically compensates for backlash, or play, between machine parts. Aimed at light-duty applications like semiconductor, packaging, medical, and other industries, it also provides a relatively high level of axial stiffness with a reduction in drag torque compared to other solutions.
