Linear Actuator - Tubular Design , High Efficiency Planetary Gear Motor Integration For Space-constrained Applications

This new kind of Linear Actuator is disclosed in China patent No 78.5. The invention comprises a linear actuator of the tubular type comprising an inner tube that is partially contained in an outer tube and arranged for displacement relative to each other along the longitudinal axes of the tubes where one of the tubes is connected to a spindle and the other tube is connected to a threaded bushing such that the mutual displacement is achieved by a rotational interaction between the spindle and the threaded bushing, wherein the actuator comprises a driving unit, the driving unit being a motor and a planetary gear , wherein the driving unit is surrounded by and connected to one of the tubes for driving the rotational interaction. The new actuator is a high efficiency in-line actuator in an elegant design with small overall dimensions for a wide range of applications. The compact design of this actuator is ideal for applications with limited space or where dimensions of the application matters. In today's fast moving markets, it is extremely important to protect the high costs of development. This can best be achieved by Patents .This new actuator use patents for strategic important areas of the developed items. This procedure also gives a high degree of security for not spending time and money on inventing something that has already been invented and protected.
