High positional accuracy in a zero-backlash gearhead
Built for OEM robotic applications, the SHD Gearhead Size 14 has a 1.5 arc-min positional accuracy and ±5 arc-sec repeatability. It has a high precision harmonic drive gearing and high-capacity cross roller bearing, with a rated torque of 33 inches-lb and a maximum torque of 310 inches-lb. It has an outer diameter of 70 mm, is only 17 mm long, and comes in 50:1 and 100:1 gear ratios. It has necessary motion control components like the harmonic drive gear and the cross roller bearing, which allows it to be incorporated into the machine housing.

Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
