INVERTER DEVICE FOR A CLOCK MOVEMENT

摘要

#CMT# #/CMT# The gear (32) has a panel with a radius, where the gear is provided with a peripheral tooth. Periphery of a central countersink (5) comprises n peripheral tips (10) that are engaged with an inverter member (25), where each tip is defined by intersection of circular hole with the periphery, where n is equal to or greater than one. The hole is secant to a portion of periphery of the countersink defined by secondary circular holes. Center of the hole is situated on a radius different from a radius passing via a center of corresponding secondary circular hole to define the tips. #CMT# : #/CMT# Independent claims are also included for the following: (1) a method of manufacturing a gear for inverter device (2) a clock movement, comprising a simple inverter device. #CMT#USE : #/CMT# Gear for an inverter device placed in an automatic winding train of a barrel spring of an automatic winding clock movement (all claimed). #CMT#ADVANTAGE : #/CMT# The gear is manufactured in a simple manner. The design of the gear enables formation of inverter device with a simple and compact structure, and reduces components for manufacturing the inverter device to reduce manufacturing cost of the device. The peripheral tips engage with the inverter member, and are defined by intersection of circular hole with periphery of the central countersink, so that the gear cooperates with the inverter member in general plane without requiring implementation of complex and expensive milling operations for formation of gear. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partially transparent simplified perspective view of installation of simple inverter in clock movement. 5 : Central countersink 10 : Peripheral tips 25 : Inverter member 32 : Gear.
