摘要： PROBLEM TO BE SOLVED: To relax an impulsive contract surface pressure load when starting a turn table-type rotary drive transmission device.SOLUTION: The center of rotation of a turn table 1 and the center of a kelly rod 4 agree with each other, a gap between a torque transmission surface 11 of the turn table 1 and a protrusion 41 for transmission of a rotary drive force, which is brought into contact with the torque transmission surface 11 of the turn table 1 when the turn table is rotated in the direction of an arrow, is substantially eliminated, and a gap (α) is formed between the side of an opposite surface and the torque transmission surface of the turn table 1. Since the gap is substantially eliminated, an impulsive contract surface pressure load at the rotational starting of the turn table 1 is relaxed, the protrusion 41 for the transmission of the rotary drive force of the kelly rod 4 is hardly damaged, and a use period of the kelly rod can be prolonged to increase economical efficiency.
摘要翻译：要解决的问题：当启动转台式旋转驱动传动装置时，放松冲击式压缩载荷。解决方案：转台1的旋转中心和凯利杆4的中心彼此一致，转台1的转矩传递表面11之间的间隙和用于传送旋转驱动器的突起41 基本上消除了当转台沿箭头方向旋转时与转台1的转矩传递表面11接触的力，并且在相对表面的侧面之间形成间隙（α）以及转台1的转矩传递面。由于间隙基本上消除，转台1的旋转启动时的冲击收缩面压力负担缓慢，所以用于传递凯利旋转驱动力的突起41 杆4几乎不被损坏，并且可以延长使用期限，以提高经济效率。版权所有（C）2013，JPO＆INPIT
