LIFTACT
LIFTACT
This document provides comprehensive specifications and guidelines for selecting and using screw jacks, focusing on travelling and rotating screw jacks. It details configurations, versions, and technical features of these mechanical devices.
Travelling Screw Jacks: The load is lifted by the linear motion of the screw, driven by the nut's rotation. Versions include trapezoidal screws (high start-up friction, low efficiency) and ballscrews (high efficiency, low start-up friction).
Rotating Screw Jacks: The load is lifted by the nut's linear motion, driven by the screw's rotation, suitable for heavy loads and long strokes. Versions include trapezoidal screws and ballscrews.
Tables summarize the technical features of S.E.L. and S.E.P. screw jacks, including maximum nominal load, screw diameter, lead, and transmission ratios. Real ratios are crucial for precise calculations, especially with encoders or servo motors.
A step-by-step procedure for selecting the appropriate screw jack based on load, efficiency, and service life requirements. Key steps include choosing the type, selecting size, verifying buckling load and thermal capacity, and calculating input torque and power.
Emphasizes safety and reliability in design and manufacturing, ensuring high safety coefficients and component durability. Critical parameters include effective load "Feff" and lifting speed "V".
Guidelines for determining the optimal combination of screw lead and transmission ratio. Verification of buckling load is crucial, ensuring the maximum stroke does not exceed allowable load.
Screw jacks are designed with high safety factors, adhering to European Community standards.
Real axial force (Feff) is derived from input torque, with formulas for calculating lifting speed based on screw lead, rotary speed, and gear set ratio.
Verification that buckling load (Pcr) exceeds real axial force (Feff). Tables assist in this verification.
Thermal capacity (CT) must exceed the product of lifting speed and load to prevent overheating.
Torque required to lift a load is proportional to the load, with efficiency varying with rotational speed.
Efficiency in quasi-static conditions is discussed, with efficiency improving with increased rotational speed.
Input torque required to lift a load is proportional to the load, with a constant equivalent number used for calculations.
Efficiency depends on friction in the worm screw/wheel and screw/nut interactions, varying with rotary speed.
Motor torque must be checked against rotary speed. Motor power is calculated using a constant equivalent number.
