LINEAR ACTUATOR

摘要

PURPOSE: A linear actuator is provided to improve driving efficiency by reducing friction between respective parts. CONSTITUTION: A linear actuator comprises a rotary driving unit(7), a rotating unit(2) driven by the rotary driving unit, plural radial bearings symmetrically fixed on both ends of the rotating unit, and a cylindrical moving tube(1) of which inner face contacts with the radial bearings. The rotating unit consists of plural cantilevers deformed radially and bending control units to control the initial bending of the cantilevers. Both ends of each cantilever are formed as slope faces inclined to a rotating shaft, so that the bearings are installed in a specific angle.
