WebApr 7, 2016 · The questioner's formula is erroneous because it doesn't include the important effect of the screw thread. The "K" in that equation should include friction as well as the …
WebJan 23, 2024 · In order to design a reasonable thread connection structure, it is necessary to understand the axial force distribution of threaded connections. For the application of bolted connection in mechanical design, it is necessary to estimate the stiffness of threaded connections. A calculation model for the distribution of axial force and stiffness … WebThis calculator will calculate torque given the lead screw parameters and the required force. There are two torques the torque to raise the load and the torque to lower the load. Once the torque is calculated an appropriate stepper can be selected. Common Stepper Motor Typical Torque Ranges and Dimensions.
WebImportant Note: The UN threads standard (ASME B1.1) lists all the data for the length of engagement of five times the pitch diameter (5xP). The ThreaDoctor is more sophisticated and considers the length of engagement in the formulas. The results will equal the tabulated figures in ASME B1.1 when you set the engagement length to 5xP..
