a torque multiplier makes the toughest nut-turning jobs a snap. The gear train of such a tool increases the mechanical advantage of a ratchet in direct proportion to the gear ratio of the multiplier. For instance, using a GA184A torque multiplier, which has a gear ratio of 4.0:1, and then applying 100 lb. ft. of input, the result will provide
This handbook covers operation and service instructions for the model TM-391 torque multiplier. 2. IMPORTANT INSTRUCTIONS. 2.1 Read and understand these operating instructions before using the Torque Multiplier. 2.2 DO NOT USE AN IMPACT WRENCH ON THE TORQUE MULTIPLIER. DAMAGE TO TOOL COULD OCCUR.
Example: A HandTorque® HT 1 has a ‘Multiplication ratio of 5.2:1, so for an input torque of 1 N∙m there is an output torque of 5.2 N∙m, with a +4% tolerance. To reach the HandTorque® HT 1 maximum output torque of 1,700 N∙m the below calculation is made: 1,700 (Required Torque) = 327 N∙m (Input Torque) 5.2 (Multiplication Factor) 3.
6 sie 2018 · The chapter focuses on the mechanism of fluid circulation and torque multiplication, including fluid velocity diagrams, analysis of the angular momentum of automatic transmission fluid (ATF) circulating inside the torque converter, and torque formulations on the torque converter elements.
For any given output torque demand, for example, for a given vehicle speed on a given grade, slip increases with the loose converter, as shown in Figure 3. This means that loss increases as well (see Figure 4b). In contrast to a clutch, a torque converter can multiply engine torque.
Typical torque multiplication ranges from 1.8 to 2.5:1 for most automotive applications, up to 5.0:1 or more for static industrial applications or heavy maritime propulsion systems.
