A special feature of the CENTAFLEX X is the slender element made of a extremely tough and highly stressable plastic.
This element is torsionally very stiff, free from play, but has bending elasticity and is flexible in angular and axial directions. Moreover, it is oil resistant and withstands temperatures up to 150° C.
This element contains steelbushes, which are alternately bolted to the hubs in axial and radial direction. The radial bushes are firmly injection moulded into the element.
The axial bushes are available in 2 versions:
Standard design X
The axial bushes are firmly pressed into the element, which makes this design axially movable only within close limits, namely within the limits of the elasticity of the element. This coupling can transmit axial forces.
The axial bushes are free to slide axially in the element.
The design type X-S therefore is axially freely movable, it is a plug-in type and free from axial forces, provided there is axial play. It is used for fitting in closed housings where blind fitting is necessary and especially where larger axial movement is required.
With the introduction of the torsionally stiff element of the series X design, and using existing construction parts, the CENTAFLEX system is most economically extended to new areas of application, e.g. pump drives (especially with radially removable spacer pieces), cooling tower drives, air conditioning, printing machines, packaging machines, step motors, tachometer drives, hydraulic drives, com- pressor drives.
Advantages and features
• Simple, compact, smooth-face design
• Low weight, low inertia
• High performance, high permissible speed, large permissible bores, rupture-proof
• The torque is transmitted absolutely evenly and free from play
• The coupling is free of maintenance
• The element is airflushed all around, the heat generated is easily conducted away and it remains cool
• The elements can be dismantled transversely without any axial displacement
• By slackening the axial screws, the drive can easily be disconnected and rotated without dismantling
• No axial reaction forces are imposed on the shafts and bearings as a result of the transmissions of torque.
