TYRE COUPLINGS Quality Products for Mechanical & Fluid Power

an excellence in engineering www.jbj.co.uk/tyrecouplings.html tyre couplings cushion the effects of overloading, absorb vibrations, reduce noise and protect your system from the destructive effects of vibration. With a flexible body that compensates misalignment and protects other components in the transmission system, UNE-FLEX couplings can be produced in accordance with the requirements of regulation 94/9/CE (ATEX 95) of a group ll device, category 2G or 2D (zone 1) and temperature class T4. The fundamental element of the UNE-FLEX tyre coupling is a rubber tyre reinforced with a synthetic...

Une-Flex Tyre Couplings General Characteristics The UNE-FLEX coupling eliminates the need for exact alignment. Its ability to achieve multiple displacements surpasses more complex coupling mechanisms, and operates with the simplicity and safety of a modern rubber tyre. This new coupling has been made possible by the technological advances that have contributed to the wonders of present day rubber tyres, designed to carry huge loads at high speeds and to withstand tremendous impacts. UNE-FLEX couplings can be produced in accordance with the requirements of regulation 94/9/CE (ATEX 95) of the...

Une-Flex Tyre Couplings fflune Selection: Couplings: In order to determine the type of coupling to be used the following formula should be applied: hp- . 7017. k n M = nominal torque. N = Driving-motor power (hp or kW). n = Minimum speed of the connected axles (rpm) k = Multiplying factor The value obtained on applying the formula should be less than or equal to that indicated in the tables of sizes and powers that refer to the corresponding coupling in the column "nominal torque". Value of K-Coefficient Notes: The values indicated in the above table are by no means applicable to every...

Une-Flex Tyre Couplings Example: The elevator bucket is driven by a motor of 16 kW; n=1.450 rpm., by means of a reducer whose outlet shaft rotates at a speed of n= 180 rpm. The motor and reducer are protected by a UNE-FLEX flexible shaft coupling. 1. Coupling Between Motor And Reducer Elevator buckets figure in group 2 of the classification under "variable load machinery". The multiplying co-efficient k = 1,5 figures in the k value table under heading 2 and in the classification of machines driven by "electric motor". Then, according to the power table. the appropriate coupling for a torque of...

Une-Flex Tyre Couplings 1. Join the two halves of the coupling and fastening rings to the pivots of the shaft. 2. Draw back the machine with the two halves until the N measurement, as indicated in the table, is reached. 3. Align the shaft until distance ‘N' between the two halves of the coupling is reached. Normally, it is sufficient to carry out adjustments with simple measuring tools since small inaccuracies in the coupling assembly can be permitted. For high speed couplings, it is recommended to adjust more accurately with a gauge, since, if this is not done, the subsequent knocking...

Une-Flex Tyre Couplings Damping & Torsional Stiffness Resonance takes place when ^ j lies between ^ and^ Jjp j= 2 When p >3, the isolation can be considered as good. Fp = Perturbing frecuency.
