The function principle of a torque multiplier. High Output Torque = Low Input Torque x Revolution. 5x 1:5 1x Why use a torque multiplier? The longer a lever arm the higher the force action. But espacially when it comes to industrial screw connections from a certain torque value onwards this basic physical principle is no longer practicable. In case of high torque values it is even no longer possible. For instance, a torque value of 9,500 Nm cannot be reached with a torque wrench in accordance with the lever rule which says that the distance to the fulcrum determines the rotational effect of the applied force. Torque multipliers provide a remedy. They substitute the classic lever principle by the physical formula: Torque (Output) = Torque (Input) x Revolution. It is thus the number of revolutions that determines the output torque, not the lenght of the lever. Effective gearing as a standard. Torque multipliers can be compared to adapters which multiply the applied force (= the input torque) with the help of a gear without having to use long lever arms. The multiplying effect depends on the gear ratio of the gear used. MATADOR torque multipliers are equipped with high quality ball-bearing precision planetary gears that have an additional overload protection. Thanks to the effective gear ratio the desired output torque is easy to calculate and complicated correction tables are things of the past. Torque multipliers are very robust and designed for continuous operation under industrial conditions. They should not be missing in any workshop. 3.3 TORQUE MULTIPLIERS Function example Input torque = 300 N·m Gear ratio 1:5 Output torque = 1500 N·m Based on a gear ratio of 1:5, 5 revolutions at the input (with an input torque of 300 N·m) are required in order to achieve 1,500 N·m as the output torque. Input torque and output torque are regarded as constant, the power is only determined by the number of revolutions. 28 www.matador.de High quality tools and more since 1900.
