What is a torque multiplier

Among its benefits are upgraded safety, greater precision and better efficiency and productivity. Torque multiplier allows reducing the lever length or operation effort by a factor of2 or 125.

Accuracy of the torque value improves when applying torque smoothly and slowly. A torque multiplier is a device that increases the torque that can be applied by an operator. If you think of a seesaw, you already know that the more leverage you have over whatever it is that is trying to be lifte the easier it becomes to do. Review the torque multiplication factor for the individual model of torque multiplier, then set the wrench based on these specifications.

For example, if the desired torque output is 4lbf. Make sure you don’t exceed the maximum input torque. If you look in any tool box you are bound to find screwdrivers and a few wrenches. This video is unavailable.

Different types of torque multipliers are best suited for different applications. No gearbox is 100% efficient and so the velocity ratio (the number of turns that the input has to make to achieve one revolution of the output) is not the same as the torque multiplication ratio. Apply more torque than your wrench can deliver on its own.

Internal gears multiply the amount of force (or torque ) that can be applied to the fastener. Use a multiplier with a torque wrench to ensure you do not exceed the maximum input torque. Place the torque multiplier assembly on the fastener with the reaction bar securely restrained against a fixed object or surface.

Through a relatively simple arrangement of gears a torque multiplier makes the toughest nut-turning jobs a snap. High ratios allow the use of a small torque wrench. Robust construction means minimal maintenance and long life. Supplied in carrying case with replacement square drive.

In hand torque multiplier there is a planetary gear system which is used to perform the function of torque multiplication. A reaction arm is fitted to the torque multiplier which resists the opposite motion of the annulus (the outer case of the multiplier ) to the input torque. Manual torque multipliers offer a range of output torques from manual inputs that can easily be achieved by an operator, providing accurate, efficient torque multiplication for make-up or breakout of joint fasteners.

The gearing design allows for a high torque output with minimal input. Commonly used in petrochemical. Power generation, transportation, shipping and maintenance industries.

I believe that the intent is not to make a torque multiplier, but rather to adjust a nut that is only accessible in this way. For the purpose of discussion let’s say this wrench is inches from center of wrench opening to center of square drive. It will be used with the torque wrench in line with the axis of the extension wrench.

Torque Multiplier Lug Nut Wrench - Cheater Wrench 4. The multiplier should be vertical when in use to avoid damage. The support arm should be on the same level as that of the socket or connector. The motor stops once the pre-set torque is attained. Check airflow with the tool in the running mode.

The gear train increases the mechanical advantage of a ratchet in direct proportion to the gear ratio of the multiplier. We perform the sourcing duties for many different products saving administrative costs by streamlining purchases, deliveries and invoicing. Not all multiplier wrenches are quality.

So, to help you find your ideal pick, we have scoured the market to get you the best options on the market. The sun gear (yellow) is driven by an input torque. The planet gear carrier (green) provides the output torque, while the ring gear (red) is fixed.

The tool has multiple user-programmable configurations for control, such as torque, angle and gang count. While not too many of our readers will likely need the kind of torque this tool produces, some will.

Torque output calculations are therefore a matter of simple arithmetic with little risk of incorrect bolt loading due to conversion errors. The Norbar HandTorque is the most comprehensive multiplier range available.
