Title: Power transmission device
Inventor: NOSAKA MICHIYASU
IPC: F16H35/10
Filed: 2002-05-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a power transmission device for interrupting transmission of power within a predetermined operating range.   <P>SOLUTION: In a transmission pathway, a dumper 13e is located at a compressor 1 side nearer than a pin 14 serving as a torque limiter portion. Thereby, torque fluctuation generated in the compressor 1 is absorbed in the dumper 13e, so that the torque fluctuation transmitted to the pin 14 gets small. Accordingly, as a range of the torque fluctuation acting on the pin 14 gets small to make lower limits lower, the operating range is widened to make development and design of the torque limiter easy and further a malfunction of the torque limiter is sufficiently prevented, even when difference in the operating range due to variation in its manufacturing is generated.  <P>COPYRIGHT: (C)2004,JPO
