Title:
POWER TRANSMITTING DEVICE FOR TRANSMITTING EXTERNAL FORCE INTO ROTATING BODY, AND ORBITAL PIPE CUTTING DEVICE AND HYDRAULIC CHUCKING DEVICE ABLE TO FREELY CONTROL CUTTING TOOL MOVEMENT INSIDE ROTATING BODY BY USING THE POWER TRANSMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/141998
Kind Code:
A1
Abstract:
Disclosed are: a power transmitting device that can be used to freely control specific objects inside a rotating body, which rotates at high speed, by directly transmitting an external force into the rotating body while the rotation remains unaffected; and a pipe cutting device and a hydraulic chucking device using the power transmitting device. The power transmitting device according to the present invention comprises: at least one linked-movement cylinder which is fitted in such a way that a rod projects to the side of a main body, on the back surface of the rotating body; a push part which is provided towards the main body so as to have at least one pusher projecting towards the rotating body; and a bearing which is coupled so as to perform an axially rotating action and perform an action whereby an axially-oriented load is transmitted, between the pusher and the rod. Such a power transmitting device can be used as a pipe cutting device by fitting a cutting tool that performs a reciprocating movement due to a hydraulic cylinder at the front of the rotating body, and by constructing the hydraulic cylinder and the linked-movement cylinder as a hydraulic closed circuit. Additionally, the invention can also be used as a hydraulic chucking device by constituting a plurality of the hydraulic cylinders of the rotating body, and by fitting jaws to each hydraulic cylinder.
