Problems solved by technology

[0007] However, in the composite coating described in Patent Document 1, although it is possible to prevent the coating film on the surface of the pinion on which pointers such as the hour hand and the minute hand are mounted, from rolling up, since the composite coating is formed by electroless plating treatment, it is impossible to make the composite coating The surface of the coating is smooth enough
That is, there is a problem that even if the composite coating described in Patent Document 1 is applied for the purpose of imparting wear resistance and lubricity to the frictional sliding portion and switching portion of a timepiece component, sufficient wear resistance cannot be imparted. and lubricity

Embodiment Construction

[0039] (The overall structure of electronically controlled mechanical clocks)

[0040] Embodiments of the present invention will be described below with reference to the drawings.

[0041] FIG. 1 is a schematic plan view of a timepiece 100 according to this embodiment, and FIG. 2 is a partial sectional view of the timepiece 100 . In the present embodiment, the timepiece 100 is a wristwatch having a structure in which generated power is obtained by rotation of a rotary weight when the wrist is moved, and a secondary battery is charged with the generated power. In FIG. 1 and FIG. 2 , the timepiece 100 has: a rotary weight 110; a speed-increasing gear train 111 that transmits the speed-up of the rotation of the rotary weight 110; a generator 120 that generates electricity through the rotation of the rotary weight 110; The secondary battery 130 in which the electric power generated in 120 is stored; and the circuit module 140 driven by the electric power generated by the generato...

Abstract

The invention provides a clock component and a clock having the clock component which increases the abrasion resistance property and lubricating property of a friction sliding part and a switching part. The upper and the lower pivot shaft of a rotor (121) are bore by a jewel bearing (150) assembled between a wheel-train clapboard and a main board (220). The rotor (121) is provided with the lower pivot shaft (124) arranged at the lower part of the rotor (121). The jewel bearing (150) consists of a red jewel and etc whose middle is formed with a pivot-shaft hole (151). The surfaces of the rotor (121) and the lower pivot shaft (124) are covered by a composite plate (160). The composite plate (160) comprises a nickel plate (161) formed through electroplating process and a graphite layer (162) which is formed through dispersants such as PAA in such a way of being exposed from the surface of the nickel plate (161). Therefore, the rotor (121), the lower pivot shaft (124), and the pivot-shaft hole (151) slide with the graphite layer (162) arranged among.

Description

technical field [0001] The present invention relates to a timepiece component and a timepiece having the same. Background technique [0002] Conventionally, there are known timepieces that use energy such as a battery or a mainspring to move hands. In such timepieces, timepiece parts are used that have a friction sliding part that slides in contact with other timepiece parts, or a switching part that switches a contact state with other timepiece parts according to an operation of operating the timepiece. For example, as a timepiece part having a frictional sliding part, a pinion and a pivot of a wheel train part for a watch can be exemplified, and as a timepiece part having a switching part, a hand lever and a clutch constituting a hand setting mechanism can be exemplified. pole etc. [0003] Here, the friction sliding part and switching part are easily worn due to point contact with other timepiece components, so in order to impart wear resistance and lubricity, the frict...
