Title:
SHAFT COUPLING
Document Type and Number:
WIPO Patent Application WO/2017/094171
Kind Code:
A1
Abstract:
A slotted-type rigid coupling (1) is manufactured so that the internal-diameter dimension of a first shaft hole (5) of a circumferentially divided shaft-fastening part (16) is the same as that of a shaft (6). The first shaft hole (5) is widened by widening force from a pressing mechanism (4) provided with a fastening bolt (3), and the shaft (6) is inserted through the first shaft hole (5) up to a shaft insertion hole (18). The widening force is ceased, the first shaft hole (5) is narrowed by fastening force from the pressing mechanism (4), and the shaft (6) is securely fastened. When the shaft (6) is securely fastened to the shaft-fastening part (16) by the fastening bolt (3), eccentricity in the shaft (6) is prevented or minimized.
