Technical calculations

■Lead screw・Lead screw nut selection steps.

Calculate Contact Pressure P and Sliding Velocity V based on conditions of use to check that no abnormal wear will occur.
Plot the calculated P and V values against the PV value graph and confirm the intersection.
If the intersection falls inside of line ① and ②, it is determined that abnormal wear would not occur.

Determine conditions of use.

Lead screw・lead screw nut temporary selection

① Contact surface pressure P, ②Sliding speed V calculations.
Verify that the value is within ① and ②of the PV value graph.

Calculate screw efficiency η and load torque T.
