Abstract
The utility model discloses a winding mechanism of a miniature automatic-hammer mechanical watch. A winding ratchet is connected with a barrel shaft square tenon inside a barrel. Three automatic wheel parts are respectively arranged between a main clamping plate and a clamping plate. A ratchet which is arranged between the main clamping plate and a covering sheet is further engaged with the automatic first wheel part and rotates in a single direction. A commutation wheel sheet is fixedly jointed on the outer ring of a first bearing. The inner ring of the first bearing is fixedly jointed on a swing plate. The swing plate is fixed on the covering sheet through the inner ring of a second bearing. An miniature automatic hammer is fixedly jointed on a hammer wheel which is fixed on a position pin pipe. The position pin pipe is fixedly jointed on the inner ring of a third bearing. A commutation wheel reed is fixedly jointed on the covering sheet. The ratchet arranged inside the automatic winding mechanism is engaged with the automatic first wheel part. When the miniature automatic hammer changes its direction, the rollback idle running of the winding ratchet is reduced. A detent spring is further eliminated. Two bearings are additionally arranged on a commutation wheel. The friction loss is alleviated. The winding mechanism has good structural manufacturability and increases the winding efficiency of the miniature automatic hammer.
