Reciprocating linear motion drive
Staff
General DPN
The Amacoil/Uhing model RG linear drive features mechanical control over travel direction and linear speed, and is said to eliminate the need for an electronic control system. Reversal of travel direction is automatic regardless of the speed or rotational direction of the shaft. Length of travel is increased or decreased using manually set end stops.
Travel speed may also be regulated using a manual control on the drive unit without requiring changes to motor speed or gearing. Available in 17 sizes, the RG drive meets axial thrust requirements from 7 to 800 lb. Backlash is eliminated with machined “rolling ring” bearings which maintain constant point-contact with the shaft. When the shaft rotates the rotary motion is immediately converted to linear motion output. There is no play or free movement between shaft and bearings including during reversal.
