<P>PROBLEM TO BE SOLVED: To provide a shaft coupling having a function of shaft lock and torque transmission and improved to attain cost reduction and miniaturization by reducing the number of parts and to be advantageous in assembly and management. <P>SOLUTION: The shaft coupling interlockingly connects the drive shaft 1 and the driven shaft 2 while having a locking mechanism n and a torque transmitting mechanism t, wherein the torque transmitting mechanism t is formed by engagement of a recess 7 at a shaft end 1a of the drive shaft 1 and a projection 8 at a shaft end 2A of the driven shaft 2 and the locking mechanism n is formed by screwing and fitting a tubular body 12, which has a right-hand female screw 15 at one end and a left-hand female screw 16 at the other end, astride a right-hand male screw 4 formed on a counter-shaft end side of the recess 7 at the drive shaft end 1A and a left-hand male screw 9 formed on a counter-shaft end side of the projection 8 at the driven shaft end 2A. The recess 7 is the tip-flared recess having a pair of opposed taper surfaces 7A, 7A and the projection 8 is the tip-narrowed projection having a pair of contact surfaces 8A, 8A which can respectively surface-contact with the pair of taper surfaces 7A, 7A. <P>COPYRIGHT: (C)2010,JPO&INPIT |
