REVOLEX® KX-D pin & bush coupling  with clamping set KTR 650

Pin & bush coupling with clamping set for frictionally engaged torque transmission

The flexible coupling REVOLEX® KX-D made of steel with KTR 650 is a fail-safe pin & bush coupling with clamping set.

Large drives often do without a feather key connection.
Transmitting torques with smooth drive shafts requires frictionally engaged connections. This is typically done via oil press fits. For that purpose the bore needs expensive grinding, the hub is heated and the shaft cooled for mounting.

With the pin & bush coupling REVOLEX KX-D with clamping set KTR 650 assembly and disassembly is simply made with a CLAMPEX clamping set. For that purpose the clamping set is screwed to a coupling flange having the benefit that the solid hub body is replaced by the clamping set. Having unscrewed the clamping screws the coupling flanges including the pin can be radially dismounted.

Safe torque transmission via the REVOLEX pin & bush coupling

REVOLEX® are torsionally flexible, fail-safe pin & bush couplings that are mainly used in applications with high torques and drives subjected to shocks. They are specifically solid, fail-safe, compensate for any kind of shaft displacement while transmitting the torque reliably.
The REVOLEX pin & bush couplings can be plugged in axially and are characterized by short dimensions. These pin & bush couplings are generally equipped with hydraulically dismountable pins which means that special tools are not required for disassembly. The coupling components of the REVOLEX® pin & bush couplings are maintenance-free and allow for a smooth disassembly of elastomer rings along with pins in mounted condition.

REVOLEX® pin & bush couplings are usually provided with 80 ShA NBR elastomer rings with the standard material being a true all-rounder. NR elastomers are available for low temperature applications. Apart from that backlash-free, electrically insulating NBR elastomers (coloured in blue) are available which are mainly used in cableway drives.

Small pin & bush couplings are relatively expensive with the REVOLEX commencing from a rated coupling torque of 4,300 Nm. The product ranges ROTEX and POLY-NORM are available for low performance ranges.

The pin & bush coupling is made up of two hubs identical in design. Pins and pocket holes alternate on the outside pitch circle of the hubs. The torques are transmitted via the steel pins with taper elastomer rings and the respective bores of the sleeve hub.

Any kind of shaft displacement, e. g. generated by inaccurate alignment of driving or driven elements, is reliably offset and vibrations as well as torque shocks are excellently compensated.
The pin & bush coupling is maintenance-free and used in general engineering as well as pump industry, conveyor technology, etc. Torques up to 1,220,000 Nm are available in 21 sizes for an optimum adaptation to the respective application. As a result customized solutions are available along with the standard product range.

REVOLEX KX-D holds the maritime type approval such as BV Bureau Veritas; ABS American Bureau of Shipping; DNV.GL Desk Nord Veritas. With maritime applications there are special demands acc. to EN 10204 (3.2) on hub bodies and pins.

Applications of our REVOLEX pin & bush couplings: REVOLEX pin & bush couplings are mainly used in safety-relevant applications, drives subjected to shocks with severely high speeds, e. g. marine technology, conveyor technology, chemistry parks, biogas plants, etc. The pin & bush couplings have a fail-safe design operating reliably with rated torques from 3,800 to 1,220,000 Nm.
