LOADTORQUE CALCULATION AND DETERMINATION OF MAXIMUM AXIAL LOAD ONTHE PNCE CYLINDER Load torque The load torque is a function of an applied axial load on the PNCE and can be calculated as follows: Faxial × l Mload = 2000 × π × η When the motor side drive (MSD) is taken into consideration: Faxial × l Mload = 2000 × π × η × i Mload Load torque [Nm] Faxial Applied axial load on the PNCE [N] l Ball screw lead [mm] η Mechanical efficiency ≈ 0,9 [-] i Gear ratio [-] It should be noted that the load torque Mload must never exceed the maximum drive torque Mp . Maximum axial load on the PNCE Application conditions example: • PNCE 40 with ball screw 16×5 • Absolute stroke = 500 mm • Extended piston rod E = 0 mm • Travel speed vmax = 0,2 m/s • Using motor side drive type T1 with a gear ratio i = 1,5 • Mounting: simple – simple mount with SGS and SBG attachment Using the diagram of the maximum axial loading as a function of the absolute stroke, the maximum axial load depending on the given mounting case can be obtained as Fmax = 700 N. Using the diagram of the maximum axial loading as a function of the travel speed, the maximum axial load depending on the ball screw lead and absolute stroke can be obtained as Fmax = 4700 N. For a selected motor side drive, the maximum drive torque Mp, MSD = 2 Nm can be found (technical data table). Using the equation for the load torque calculation when the motor side drive is taken into consideration, the maximum axial load Fmax = 3392 N can be calculated. For selected mounting attachments, the maximum axial load is limited to the maximum axial load of the PNCE, i.e. Fmax = 6020 N. Finally, for this application example, the maximum axial load on the PNCE can be determined, i.e. Fmax = 700 N. This is the smallest value of all the values obtained in the previous steps.
