Filed: 2005-12-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a shaft coupling for transmitting power between two parallel shafts via a rolling element arranged at an intersecting position of guide grooves perpendicular to each other while preventing abnormal sounds and damage to components during the maximum eccentricity without increasing the size of the coupling.  <P>SOLUTION: At both edges of an oblong hole 7 of a cage 4 storing a steel ball (the rolling element) 3, soft shock absorbing members 8 are mounted which are elastically deformed when receiving the steel ball 3 being moved from the center side of the oblong hole 7 to the end. Thus, the steel ball 3 is avoided from strongly colliding with the guide grooves 5, 6 of both plates (rotary members) 1, 2 or the edges of the oblong hole 7 of the cage 4 when the eccentricity is the maximum, to hardly give abnormal sounds and damage to components. At this time, an increase of resistance to the eccentricity is detected during operation to reduce the eccentricity to be smaller than an eccentricity possible limit, therefore eliminating the need for conventionally giving an allowance to a eccentricity possible range and suppressing an increase in the size of the coupling.  <P>COPYRIGHT: (C)2007,JPO&INPIT
