TYPES OF TORQUE WRENCHES
The dial-indicating torque wrench, Figure 63, indicates the amount of torque
applied at any given moment. Dial-indicating wrenches are especially suited
for jobs requiring many different torque values because the dial does not
have to be reset each time.
To measure bearing or preload, use a dial-
indicating torque wrench.
DIAL-INDICATING TORQUE WRENCH
Beam-type torque wrenches, Figure 64, are made of flexible alloy steel which
deflects when torque is applied. A pointer attached to the end of the beam
indicates the torque reading on a scale. This type torque wrench has the
advantage of simple design. It does not use a multiplying device or a cam
mechanism that can be ruined easily.
