What is the principle of the torque multiplier? What are the advantages of the torque multiplier?
Torque multiplier is a device that can help the operator increase torque. Since the power at the output does not exceed the power at the input, the number of output revolutions is lower than the number of input revolutions. The products of various brands on the market usually achieve torque multiplication through planetary gears, which are generally amplified 5 times to 125 times, and the maximum output torque can reach about 50,000 Nm. So what is the principle of the torque multiplier?

Torque multiplier principle
Â
The torque multiplier is driven by a combination of a circular or planetary gear in different combinations of layers to drive the gears to rotate. Each stage of gear torque magnification factor is 5, the conventional ratio is: 1: 4.2, 1:16, 1: 21.5,1 : 25 series. In a planetary gear system, torque is input and output via the sun gear. Three or four planet gears are combined with the sun gear to drive rotation. The circumferential gear in the multiplier housing is engaged with the inner planetary gear, but relative to the rotation of the inner planetary gear, the direction of rotation is opposite. The reaction force arm prevents the rotation of the housing integrated with the circumferential gear, and causes the planetary gear to rotate around the sun gear to drive the driving square head to rotate, thereby outputting torque.
The peripheral gear in the torque multiplier housing is engaged with the inner planetary gear, but the direction of rotation is opposite to the rotation of the inner planetary gear. The reaction force arm prevents the rotation of the housing integrated with the circumferential gear, and causes the planetary gear to rotate around the sun gear to drive the driving square head to rotate, thereby outputting torque. Without a reaction arm, torque cannot be output.

Torque multiplier advantages

Safe, use of extension rods can cause danger. Using the torque multiplier can reduce the length of the extension rod and the user's output by magnification of 4, 25 or 28 times.
Due to the limitation of operating space, the use of longer extension rods may be unsuitable for extension rods due to space constraints.
Accurate, the operation using the torque multiplier will be smoother, smoother and more accurate torque can be obtained. In the process of bolt tightening, physical expenditure can be reduced. It is quite difficult to tighten and remove large-diameter bolts and nuts in the power plant overhaul and production overhaul installation sites of various industrial industries, especially in environments where operators are difficult to construct, such as the small space around the equipment, it is not possible to use afterburners and various special Wrenches, etc., this contradiction becomes more prominent.
The above is about the principle and some points of the torque multiplier. If you want to use the torque multiplier correctly, the premise is that you choose the right tool product at all. Of course, you should also be familiar with the principle of the torque multiplier, so that you can use it. Time to be more handy and avoid those unnecessary problems.
