Uhing linear drive pitch is manually adjustable

Aston, Pennsylvania – Changing linear pitch on Uhing rolling ring linear drives uses a lever control option on the drive unit. The pitch control lever permits manually setting and changing linear pitch independently of the drive motor speed or other controls. Motors and devices in a machine may continue operating at production speed without interruption while the drive unit's linear pitch is changed or adjusted to better meet application requirements.  

Each of 17 models of Uhing rolling ring drives has a different maximum linear pitch. The smallest drive has a maximum linear pitch of 6.2mm (0.24") and the largest drive has a pitch of 76mm (3.0"). Gearing the drive shaft to the drive motor enables operators to shift the maximum pitch for a specific drive unit up or down based on application needs. For example, the model RG3-15 drive unit has a maximum linear pitch of 11.4mm (0.45") at a 1:1 gear ratio. Gearing of 2:1 makes the maximum pitch 22.8mm (0.90").

 

There are 100 notched settings on the pitch control scale. Moving the pitch control lever one notch up or down increases or decreases the linear pitch by a value of 0.01. Thus, a Uhing rolling ring drive has a linear pitch adjustability range of 10:1. Using the RG3-15 drive unit as an example, if the drive is geared for a maximum linear pitch of 22.8mm (0.90"), an operator can turn the pitch down to 2.28mm (0.09") just by moving the pitch control lever – without adjusting any other controls.

 

In addition to the 10:1 adjustable pitch range, Uhing linear drives offer axial thrust from 30N (7 lb) to 3,600N (800 lb). Pitch, thrust, and travel direction are all controlled mechanically – without clutches, cams or gears. Machine designers working with linear motion devices will find Uhing rolling ring drives provide backlash-free reciprocating motion that doesn't complicate machine design, setup, or operation.

 

Rolling ring linear drives are used in machinery requiring a component for smooth, backlash-free linear motion, such as moving measuring probes and spraying. A Uhing linear drive operates on a smooth shaft. Debris cannot get trapped in threads which then might cause clogging and jamming.
