A torque multiplier with simple calculations

摘要

Each gear stage of a Norbar multiplier has a gear ratio of typically 5.45:1, which results in a true torque multiplication factor of 5:1. While the company says other multipliers often require graphs or formulae to calculate the input torque to achieve a particular output, Norbar requires simple multiplication. Norbar claims Handtorque has the most comprehensive multiplier range available. Standard products are available for hand torqueing up to 47,500 Nm (35,000 lbfft) and special orders to 100,000 Nm (73,000 lbfft).
