LAP Series Linear Actuator

Linear actuator model selection Check duty cycle Duty cycle Fu% ACME screw linear actuator Actual load speed and stroke requirement Considering lifespan and overheat Ball screw actuator is recommend Ball screw actuator Model pre-select Check the stability according to curve page 12 Choose a bigger size if stability can not meet requirement. Ball screw actuator or not final confirmation Input version Fu%=(t2+t4+t6) / 10min Fu%= Working Percentage within 10min T2.t4.t6 : working time T1,t3,t5: waiting time Input position Duty cycle calculation Choose a bigger size if stability can not meet...

Lifetime calculation The lifetime of Ball screw linear LBP series depends on the lifetime of ball screw and worm gear and shaft, we just need to calculate the lifetime of screw, worm gear and shaft will wear but normally lifetime is longer than screw. Nut lifetime calculation: L10=(C / Fm)3xS L10: theoretic lifetime km C: Rated dynamic load N Fm: mean load N S: Ball screw lead mm Fm mean load calcuation: Load N F1 Load and speed changing curve Storke mm LIM-TEC BEIJING TRANSMISSION EQUIPMENT CO.,LTD.
