HIGH-SPEED ROTATION UNIVERSAL JOINT CONNECTION STRUCTURE OF CUTTING PROCESSING SYSTEM

摘要

PURPOSE: A universal joint connecting structure for high speed rotation of a cutting process device is provided to obtain excellent speed and efficiency of a cutting process work with respect to a cutting object by smoothly driving the universal joint even in high speed rotation. CONSTITUTION: A universal joint(10) connecting structure for high speed rotation of a cutting process device comprises a hemispherical yoke(11) in which a slot(12) is equipped at one side of the universal joint. A yoke combining member(13) in which a hemispherical groove(11a) and a pin combining hole(12a) are formed on the other side of the universal joint. A combining pin is combined in the pin combining hole and the slot by penetrating therein.
