Title:
POWER TRANSMISSION MECHANISM
Document Type and Number:
Japanese Patent JP2022094620
Kind Code:
A
Abstract:
To provide a power transmission mechanism that transmits a power generated in a drive side mechanism part to a driven side mechanism part coupled in a non-contact manner using magnetic force, the power transmission mechanism capable of detecting a lock-up on the driven side.SOLUTION: A power transmission mechanism 1 has a drive side mechanism part 10, a driven side mechanism part 35, a non-contact coupling part 60, and a lock-up determination part 71 formed in a circuit part 70. The drive side mechanism part 10 has a motor part 11, a shaft 14 as a drive side shaft, and a drive side magnet 20. The driven side mechanism part 35 has a driven side magnet 40 and a rotary member 41, and is installed separately from the drive side mechanism part 10. The non-contact coupling part 60 has a drive side magnet 20 and a driven side magnet 40 and couples the shaft 14 and the rotary member 41 in a non-contact manner by using magnetic force. The lock-up determination part 71 determines whether or not a lock-up of the driven side magnet 40 has occurred by using variation of rotary load related to an operation of the drive side magnet 20.SELECTED DRAWING: Figure 1
