Title:
METHOD AND DEVICE FOR POWER TRANSMISSION WITH LOAD-SENSING THRUST AMPLIFYING MECHANISM
Document Type and Number:
WIPO Patent Application WO/2006/030768
Kind Code:
A1
Abstract:
A method and a device for power transmission capable of converting a rotating motion into a liner motion according to loads by a simple structure, requiring low cost, and capable of providing high efficiency. A feed screw (21) and a female screw (22) with a diameter larger than the diameter of the feed screw are eccentrically threaded with each other, a reaction from a work is detected by a helical spring (28), the constriction of the rotation of the eccentrically threaded female screw (22) is released, and the female screw (22) is rotated to differentially rotate the feed screw (21) and the female screw (22) so as to reduce a moving speed and increase a pressurizing force.
