WASTE HEAT RECOVERY MECHANISM, AND WASTE HEAT RECOVERY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a waste heat recovery mechanism capable of generating electric power even when an expander is locked.

SOLUTION: A rotary shaft 40 constituting an alternator 43 acquires rotational drive force via a pulley from an engine. A cylinder part 44 is formed in an inner end part of the rotary shaft 40. A small diameter end part 59 is formed on an output shaft 70. The small diameter end part 59 is thrusted into a cylinder of the cylinder part 44, and a torque limiter 58 is interposed between an inner peripheral surface 442 of the cylinder inside 440 of the cylinder part 44 and an outer peripheral surface 591 of the small diameter end part 59. The output shaft 70 is coupled coaxially with the rotary shaft 40 via the torque limiter 58.
