Knowing more about Torque multipliers

The torque multipliers have been considered to be a gear box which functions on ‘Epicyclic Gearing’ principles. At input, given gets multipliers according to multiplication factor, which then gets transmitted at output. By placing in minimum efforts, it becomes possible to achieve greater load.

Their functioning

‘Planetary’ or ‘Epicyclic’ gear train is incorporated by hand torque multipliers, which have over one stage. The gearing’s every stage tends to have the multipliers increased by applying 5 factor, thereby allowing the multipliers to be offered in 5:1 ratios; 25:1 as well as 125:1. The multipliers within the planetary gear system get applied to ‘Sun’ gear or input gear. The teeth of 3 – 4 planet gears get engaged with sun gear to rotate. Torque multiplier’s outside casing or ‘Annulus’ as it is known gets engaged with planet gear teeth. It rotates normally to sun gear’s opposite direction. Annulus is prevented the anus is prevented by the reaction arm from rotating, causing planet gears in orbiting the sun. It is between the output and input plate that planet gears get held, also holding output square drive. Hence, as planetary gears start to orbit the sun gear, input and output plates makes square drive turns. Torque multiplier is likely not to get applied by output square, if annulus is not kept in stationary position by the reaction arm.

Why make use of Torque multiplier?

·    Accuracy: It is only upon being applied slowly and smoothly that multipliers can be accurately applied. This is enabled by having majority of physical efforts to be eliminated from tightening task.

·      Safety: It can be dangerous for using long levers. Using torque multiplier would mean the lever lengths would be reduced or factor of 125, 25 or 5 diminished in operator efforts.

·         Space limitation: Restricted space may create issues for using long levers.

Types of multipliers

Basically, there are three types of  torque multipliers which are given below:

·   Mechanical type: There are several benefits to using this type like:

Ø    For determining torque output, correction charts not required.

Ø    Stated ratio is considered to be real torque multiplication factor.

Ø  Most models come with safe, strong anti wind-up Ratchet for providing comfortable and safe operation.

Ø    There is present huge variety of reaction arms depending upon customized specifications, thereby making it adaptable to several applications.

·         Nano Series: Its features are as follows:

Ø  It has 5:1 torque multiplication and is a heavy duty, compact torque multiplier.

Ø  Enjoys higher repeatability with accuracy more than ± 4%.

Ø  Detachable reaction handle provided.

Ø  On demand, offset reaction arm optional available.

Ø  For better handling and storage, it is supplied in molded, sturdy plastic carrying case.

·         Slim type: Its features are as follows:

Ø  For low input, it has higher reduction ratio.

Ø  Its compact size can help it being utilized in constrained areas.

Ø  Input having safety shear pin is present to avoid overloading.

Ø  Output Sq. drive having pin lock mechanism to provide positive socket locking.

Ø  It offers ± 4% accuracy with great repeatability.

Knowing the different types can help the person to make a well informed purchase.
