What are the advantages and disadvantages of electromechanical actuation solutions compared to hydraulically powered solutions?
Kelston has created an online System Builder for customers to quickly and easily determine an appropriate screw jack system.
Screw Jacks are found wherever there is a need to lift, position and hold load. A Screw Jack (also known as a Jack Screw, a Worm Screw Jack, a Machine Screw Jack or a Lead Screw Jack) is a devise used to convert rotational motion into linear motion.
Worm Drives are used when the axis of rotation of a shaft must change direction. Being low-cost, potentially self-locking and providing high gear reductions, Worm Drives provide an effective means of decreasing speed whilst increasing torque.
Bevel gears are used when the axis of rotation of a shaft must change direction. Providing a highly efficient and durable means of gear reduction, Bevel Gear sets have many uses.
A screw is a mechanical system that converts rotational motion in to linear motion. In other worlds it converts rotational force (torque ) in to a linear force. Here the resultant axial force due to an input torque is calculated from first principles.
A screw thread is a helical groove formed on an internal or external diametrical surface and is described by various terms including pitch, root, crest, flank and major diameter. These terms are described here.
