Abstract

PURPOSE:To eliminate the oiling of a wrist watch and to reduce maintenance expenses necessary for a user by coating a shaft as one of the constituent annular parts of the propagating mechanism of the watch with MoS2. CONSTITUTION:A rotor pinion 1 is held by metal 4 at the positions of cogs 1a. A bush is placed under a magnet 2 set around the pinion 1. The outsides of the cogs 1a are coated with MoS2 so as to reduce friction with the shaft holes in the metal 4. The thrust section 1b of the pinion is also coated with MoS2 so as to reduce friction with the metal 4.

Description

【発明の詳細な説明】 この発明は、腕時計の伝達機構を構成する輪列の軸部構
造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shaft structure of a wheel train that constitutes a transmission mechanism of a wristwatch.

めに、定期的に分解し、洗浄、注油をする必要がある。Conventionally, parts are completed by subjecting structural carbon steel to heat treatment to harden it and polishing the tenon, but the tenon in contact with the metal (ruby) wears out and increases friction, so it is lubricated. However, due to the problem of oil deterioration and dust, it is necessary to periodically disassemble, clean, and lubricate to maintain the initial performance.
