Torque limiter with pawls category 2 - Eurocardan. Hub connection: 1 3/8 Z6 Cross measurement: 23.8 x 61.2 mm Maximum torque: 400 Nm Size C: 125mm Pawls for complete replacement: 8 Pawl files: 1 Technical characteristics and operation: The torque limiter is of the mechanical type with pawls acting in a radial direction which, when the transmitted torque exceeds the pre-set calibration value, come out of their seats overcoming the resistance offered by one or two helical springs. During operation, the pawl limiter interrupts power transmission, reducing the torque transmitted to a minimum pulsating value necessary for subsequent restoration. Transmission reset occurs automatically when the number of revolutions is reduced. The value of the calibration torque is pre-set in the factory according to the number of rows of pawls and the configuration of internal and external springs adopted and can be varied by changing the number of springs. Thanks to the residual torque reduced to a minimum, overheating and vibrations during work are also reduced. Button locking system. Special executions on request. It works in both directions of rotation as the pawls are symmetrical. Application The pawl torque limiter is recommended in cases where, following an overload, a sudden interruption of the torque is required and therefore an immediate stop of the driven machine, in order to avoid breakages of the transmission or the machine itself. The intervention of the device can be perceived by hearing the typical intermittent noise emitted during the disconnection state or by noting the inactivity of the machine itself. Maintenance The intervention of the device causes impacts and sliding of the pawls in the external body and therefore heat development: for this reason it is advisable to ensure that the slips are short to avoid excessive stress which can degrade the performance of the device. Maintenance can be performed by lubricating the device through the external grease fitting._x000D_Brand Eurocardan Production Made in Italy Weight 2.50kg
