Clamping Systems

U-Clip and easylock® Shaft collar for smooth shafts/tubes U-Clip The types U-Clip and Uhingeasylock® offer solutions for many problems at handling. U-Clip is using a clamping ring which is off-set to the shaft and therefore clamping forces are provided. Like a bushing the U-Clip is pushed foreward against the to be fixed component and it automatically locks into position. To release, just pull the clamping ring towards the user. The Uhing-easylock® System is characterized by ease of handling and its clamping/ tensioning function on smooth shafts. The result is rapid roll changing combined with high but sensitively applied retaining pressures for spools and rolls of flexible width and with varying core diameters in a modular system suitable for a variety of applications. Its main component parts are a fixed pintle and a clamping section comprising a tensioning unit and an interchangeable pintle point. Its function relates to a clamping ring which is located in the tensioning unit and which is brought into pressure contact with the shaft. The greater the tensioning force, the greater is the clamping effect of the ring. The spool or roll is retained and fixed by pushing the tensioning unit up against it and turning the tensioning wheel until the required clamping force has been achieved. To release, the clamping force is reduced via the tensioning wheel and the clamping pintle is pulled off the shaft. Also suitable for driven shafts.

Linear Drive Systems

Uhing - Linear Drive Nut Uhing Linear Drive Nuts are non-positive drives which convert the rotation of a plain shaft into linear motion. In contrast to Rolling Ring Drives, the Rolling Rings are not arranged to swivel but are fitted at a fixed angel of pitch, the speed being varied by varying the speed of the shaft. The change of direction is achieved by reversing the direction of rotation of the shaft. Backlash-free, low noise, rolling-friction giving high-efficiency, combined drive and carrier, release mechanism enables unit to be manually positioned on the shaft, compact design, small space requirement, safe as it will slip when overloaded, thrust can be multiplied by ganging-up units, available with a variety of pitches, leftand right-hand pitch on the same shaft possible, good sealing possibilities e.g. for use in dusty, dirty or humid environments. Wherever linear motion is required, the Uhing Linear Drive Nut is a modern alternative to hydraulics and pneumatics, chain drives and lead srews.

Uhing - Rolling Ring Drive RG, RGK The drive converts the constant rotation of a plain shaft into a twoway reciprocating motion and is also used in the general linear motion area. Accommodation of heavy loads and high forces when used in conjunction with additional load carrier. Standstill on rotating shaft possible with a high degree of repeat accuracy (external impulse restart). Suitability for two-way shaft rotation. Pneumatic or electromagnetic reversal. In addition to our standard range, we can supply you with tailormade solutions to your specific problems and requirements. Application areas Surface treatment / Converting Measuring and testing Materials handling / Packaging Tyre manufacture Feeds / Positioning drives Power amplifiers (servo functions) Drives for synchronous cutting machines Sequential drives / Special machines

Remote control All functions (reversal, width of stroke, speed and free-movement) can be remotely controlled. Precise repeatability of movement sequences, including different characteristics in the two directions of travel, possible via cam follower control.	Rolling Ring Principle Rolling Ring Drives are friction drives which convert the constant rotation of a plain round shaft into reciprocating motion. They operate like nuts on a threaded bar, however the pitch both left-hand and right-hand is capable of fine adjustment or can be set at zero. This effect is achieved by using ball bearing based Rolling Rings which are designed to pivot about the shaft, their specially crowned running surfaces being pressed against the shaft as it rotates.	Your benefit automatic reciprocating motion with constant direction of shaft rotation side thrust up to 3600 N width of stroke up to 5m speed up to 4.2m/sec. suitable for horizontal and vertical application variable linear output speed from constant shaft input speed rapid or speeded down reversal high reversal position dynamics can be disengaged on the shaft good sealing possibilities (plain shaft) high efficiency low operating costs high corrosion protection

Linear Drives: Uhing®-Z-Drives - Uhing® Timing belt drives The basis of the Uhing Z -Drive is a bending and torsion resistent rigid aluminium profile. A number of T-slots in the carrier section offer variable extension possibilities and simplify assembly. Slide connection blocks can be easily inserted. The transmission of power from the drive belt to the load carrier is via belt fastener fitted to the carrier. Uhing-Z-Drives are characterized by the use of high grade materials including corrosion resistant hardened guide rails and robust timing belts which retain their shape. They are precise, positionally exact, reach high acceleration rates and speeds and are built for long life.

Winding-Systems

Automatic Winding Width Control AVS

The AVS prevents winding flaws in the particularly critical reversing area. Within a specified window, it detects where a dent or bulge starts, stores its position and corrects the flaw during the next strokes. This results in an optimum pattern on the spool and ensures smooth unwinding later on.


Areas of application Wire diameter: 0.1 up to 5 mm Spool speed max. 3,000 rpm (upon request 6,000 rpm) Suitable for many spool types – deformed flanges and bi-conical flanges too Appropriate for dirt loaded environment (no optical sensors)	AVS advantages Optimum winding within the critical flange area Smooth unwinding of the wound material Optimum laying result without manual intervention Compensation for flange bulging during winding Winding is even possible on faulty or deformed spools Winding on spools with straight or conical flanges Winding on cylindrical and conical spool cores Up to 10 spool types can be stored Commercially available components

Uhing®-Guide System GS Uhing®-guide system GS transmits the traversing movement of the traversing unit to the guide roller and the material to be wound. Additional modules allow the system to be universally matched to the winding task. Advantages: Modular construction for easy adaptation to the winding task continuously adjustable Torsionally rigid adapter for assambly on Uhing Rolling Ring Drives KI, RG15, RG20, RG22 and RG30 made entirely of stainless steel versatile attachment options for guide rollers suited for all traversing systems





Uhing®-Non-Contact Flange Detecting System FA Function Sensors (reflection) scan the inside of the spool flanges and trigger the reversal of the traversing movement. As an alternative, light barriers can be used for flange scanning. Scope of delivery: Uhing® rolling ring traversing system with pneumatic reversal Optical sensors or light barriers with adjustable forward movement PLC for controlling the reversal time Determination of the shaft speed by a reed switch Connection requirements: For optical sensors: constant reflection conditions and flange geometries. Power supply: 85 - 264 V AC 47 - 63 Hz Pressure: Max. 6 bar Advantages: Once the system has been set up for a spool type, the points of reversal need not be adjusted after a spool change, and no readjustments are required during winding. Easy to connect Existing Uhing rolling ring drives can be retrofitted Inexpensive Uhing®-Non-Contact Flange Detecting System.

Your Benefit No readjusting of reversal points after spool change No readjusting during winding Easy to install Low price	Function A sensor (light barrier) detects the coil flanges and trips the reversal of the traversing unit. When the speed of the traversing shaft decreases proportional to the filling rate of the coil, the length of travel of the traverse is reduced as the reversal time remains constant. To compensate this stroke reduction, a PLC can be supplied.	Description The traversing system is based on the tried and tested Uhing rolling ring drive that mechanically converts the traversing shaftís constant direction of rotation into a permanent traversing motion. It features a pneumatic system triggered by a light barrier instead of the conventional spring-actuated reversal system. The light barrier travels on the traversing system and is fastened such that the spool flanges interrupt its light beam at each stroke end, thus triggering the reversal.
