<p>PROBLEM TO BE SOLVED: To provide an operation motor set which is installed in an electronic lock.SOLUTION: An operation motor set includes: a fixed socket provided with a housing chamber; a motor fitted to the fixed socket and provided with a rotary shaft; a power transmission set which is provided with a worm fitted to the rotary shaft, and teeth provided on the worm and not completely distributed and drawn until a propulsion end and a reduction end as both ends of the work are reached; and a spring in which a connection part is hooked on the teeth, a portion other than the connection part is a pressing part, an inner diameter of the pressing part is larger than an outer diameter of the teeth, the spring receiving spiral pressing pressure of the teeth by the rotation of the worm, moving forward and backward on an a shaft of the worm, when moving to the propulsion end of the worm, forming idling without movement due to mutual hooking of the teeth, and when inversely moving to the reduction end, forming idling without movement due to mutual hooking of the teeth. The operation motor set prevents an overshoot phenomenon when an operation motor is driven.</p> |
