PURPOSE:To relieve the shock in the rotary direction effectively in the idle time untill reaching to the ballancing, by rotating an armed nut through the driving force of the primary rotary shaft of a shaft coupling and pressing one buffer material then compressing untill ballancing with the start torque of the secondary rotary shaft. CONSTITUTION:A secondary rotary shaft 3 is inserted through an angular hole 2 in a screwed boss 1. Then an armed nut 5 is screwed with the screw 4 of said boss 1 and one 8B of the stoppers 8A, 8B secured to both ends of said screw 4 is used as the fixed nut. Furthermore a metal seat 9 and a circular buffer material 10 are placed between both faces at the boss section of the armed nut 5 and the stoppers 8A, 8B, and under the state where the both faces at the boss section of the armed nut 5 are held by the stoppers 8A, 8B through the fastening of the stopper 8B, the driving force of the primary rotary shaft is applied on the arm 7 of the armed nut 5 to rotate the armed nut 5 thus to compress one buffer material 10 untill it is ballanced with the start torque of the secondary rotary shaft 3 and to transmit the rotary force to the secondary rotary shaft 3. In the idle time until said transmission, the buffer in the rotary direction is relieved. |
