Calculation of Ball Screw Thrust

Thrust in the drive direction of the screw

background origin

Why do this Lead Screw thrust calculator?

First of all, because the current work requires frequent selection of the matching lead screw and motor, it is quite troublesome to calculate the thrust of the lead screw manually. A formula needs to be transformed over and over to calculate different variable values.

In addition, the calculator scientific mode provided by WIN 10 has no pi value, which is very inconvenient to calculate, and the results cannot be saved and compared with each other, so there is this screw thrust calculator.

basic introduction

The screw thrust calculator can arbitrarily calculate the value of any variable in the screw thrust formula, and can save the calculation results for easy selection and comparison.

Instructions

Open the program, click the "Result" radio button on the variable to be calculated, then fill in the values of the other three variables, click "Calculate" (you can also use the F5 shortcut key) and the result is calculated.

The results of each calculation are saved in the table on the right. The data in the table can be cleared manually or the specified items can be deleted.

Thrust P=2πηT/L
η: screw transmission efficiency, about 0.9~0.95
T: torque
L: screw lead

It is necessary to pay attention to whether the length units in torque T and screw lead L are consistent. If T is in kg*cm and screw lead L is in cm, the calculated result is kg. If T is in N*m and screw lead is in cm or mm, it must be converted.
