Portescap (West Chester, PA) has introduced the R08 planetary gearhead that delivers continuous torque of 0.05 Nm within an overall envelope of 8 mm. The standard gearbox is available from 4 to 256 ratios, which can be further extended to ratios of 4096. The gearhead can be coupled with brush DC, brushless, and stepper motors in their respective frame sizes. It can also be customized to meet specific customer requirements. Design improvements include a crimping process performed along with the press fit that increases strength and shock absorption capacity. A monobloc shaft reduces the total number of components. The gearheads are suited for use in medical applications, imaging (collimators, radiography), and security and access applications; and in instrumentation applications such as industrial robots.
