PAGUFLEX® PLUS shaft couplings... the sure, uncomlicated, economical solution, if angled, radial and/or axially displaced drive shafts are to be frictionally connected.

PAGUFLEX® PLUS shaft couplings

The double loop-shaped, thermoplastic compensating element of the coupling HYTREL®, a Thermoplastic Ether Ester Elastomer (TEEE) from DuPont.

Owing to the hogh reverse bending strenght of the flexible material and the cardan-like shaping of the power transmitter, this development is the ingenious, technical solution for shaft displacement problems in motive power engineering and in measurement and control techniques.

Recommendations fpr our products come from the design of:
shaft-anle encorders, counting mechanisms, tachogenerators, servo valves, elevating tables, feeding drives, pumps, compressors and ventilators, kitchen equipment, office systems, textile machines and for numerous applications in the automobile and aircraft industries.

The one-piece coupling works frictionless, waerless and silently, and without any troubling effects (i. e. without troubling structure-borne sounds).

Thus in changes of direction of rotation or during torque fluctuations with load direction reversal, PAGUFLEX® PLUS enables play-free and shock-free power transmission, together with effective vibration damping and sound insulation.

In noumerous technical applications the material HYTREL® has been successfully substituted not only for established thermoplastics but also for elastomers. In combines ideally the advantages of both materials and therefore is the innovation for flexible shaft couplings.

It enables the opening up of new areas of application in extremely low and high temperatures. Also in association with media in which owing to their sensitivity elastic elements have shown themselves to be of `limited use´. Further applications are those in which up to now the reverse bedning strenght of the material has set narrow limits with regard to mechanical fatigue loading. In these,
PAGUFLEX® PLUS is now the solution.

The high flexibility of the thermoplastic coupling element effectively lightens the burden of the shaft bearings of motors and machines even in circumstances of large radial and angular, alignment errors. With the help of PAGUFLEX® PLUS, the bearings run quieter, warm up less and achieve longer durability, thus lengthening service life.

 

PAGUFLEX® PLUS - plus points

The double loop coupling uses a moulded plastic element permanently swaged to steel or stainless steel hubs to give a compact design. It forms an effective two-stage coupling with exceptional flexibility in all three modes. Ideal for transmitting rotation in small drives, this type of coupling works without any friction, wear or noise, although its low torsional stiffness makes it less suitable for high precision positioning applications.

Exceptional flexibility in all three directions: radial, angular and axial.

Coup-Link is a full line of zero backlash flexible shaft  including Beam, Bellows, Jaw, Disc and Oldham.  All are available in a variety of mounting options including set screw, keyway, clamp, conical and shrink disc configurations.

Beam, Disc, Jaw, Bellow, Encoder and Oldham couplings

Motors, reducers, encoders, shafts and other rigid elements often fail prematurely. Many times this is from misalignment, which often leads to bearing, shaft or seal failure. Zero backlash, flexible shaft couplings  accommodate parallel and angular misalignment and shaft endplay.

Properly selecting a Candy Coup-Link provides the flexibility to handle many types of misalignment and may offset problems such as minor design errors or improper assembly.
