Linear drives adjust for pitch
Once pitch is set on a Uhing drive, it remains constant regardless of the drive motor speed or other control settings.
Uhing "rolling ring" linear drives now feature a mechanical pitch adjustment lever, enabling a variable pitch drive system without requiring gear changes or adjustment of other controls Users adjust pitch by moving the selector lever along a notched scale

Catalogue details "rolling ring" linear drives
The just-published RS linear drive catalogue from Amacoil/Uhing provides complete descriptive and design engineering information for using "rolling ring" linear drives in positioning and indexing.
Each notch on the scale corresponds to a discrete pitch setting.
Changing between notches causes changes of a factor of 0.01 on Uhing models RG15 through RG40 and by 0.02 on models RG50 through RG80.
If a more precise pitch adjustment is required, a worm gear and threaded rod design bypasses the notched-scale settings.
Users turn a control knob on the end of the threaded rod, which permits fine tuning of linear pitch on-the-fly without stopping the drive system.
Once pitch is set on a Uhing drive, it remains constant regardless of the drive motor speed or other control settings.
The Uhing pitch adjustment lever eliminates the need for gear reducing devices and minimises electronic control requirements.
Machine design, setup and operation are thereby simplified.
Both the notched scale and worm gear options for pitch adjustment are available on all seventeen sizes of Uhing model RG linear drives.
Besides linear pitch, travel direction of the drive nut is also mechanically controlled independently of the motor and controls.
Uhing rolling ring drives are used in machinery that requires smooth, backlash-free linear motion.
Applications include packaging/converting machinery, sealing equipment, traversing material onto a reel, moving measuring probes, spraying/scanning set ups and other processes involving repetitive back-and-forth linear movement of tools, materials and equipment.
