Abstract
PURPOSE: To reduce stress concentration and increase strength by providing cut lines alternately, each having a circular hole at its ends.
CONSTITUTION: Of cut lines 1 provided on flat plate 10, cut lines 1 perpendicular to the shaft are arranged alternately. Joint 4 of vane part 2 and machine part 3, surrounded by cut lines 1, is taken large. Circular holes 11 provided at the ends of cut lines 1 reduce stress concentration at joint 4. Consequently, by providing cut lines 1 alternately, the cross section of the break part, due to the centrifugal force and the impulsive force, is made large compared with conventional devices. By providing circular holes at the ends of the cut lines, stress concentration is reduced compared with conventional devices. By this, it is possible to increase the strength of the joint against the centrifugal force and the impulsive force markedly.
