Clock movement

Abstract

The invention relates to a clock movement. The time travel system of the clock movement comprises a wind-up mechanism for providing a power for a second hand, a minute hand and an hour hand, a power transmission wheel train matched with the wind-up mechanism and used for driving the second hand, the minute hand and the hour hand to run, and an escapement pallet swing mechanism for limiting the rotation speed of the power transmission wheel train, wherein the escapement pallet swing mechanism is composed of an escapement mechanism and a swing wheel assembly, and the escapement mechanism comprises an escapement wheel and an escapement pallet, and the swing wheel assembly comprises a swing wheel, a swing wheel shaft, a hairspring and an index lever adjustment rod; the swing wheel is a plastic part or a plastic electroplated part which is injection-moulded by a die, and the swing wheel shaft is a metal part. According to the clock movement disclosed by the invention, the problems of high manufacturing cost, high machining difficulty, difficult accuracy control, liability to break a swing tip, and the like of the swing wheel are solved; meanwhile, the problems of high weight of a tourbillon component, and liability to break and incline the central shaft of the tourbillon component can also be solved, the time travel accuracy of mechanical parts can also be improved through an electronic control system, and the problem of low time travel accuracy of a mechanical watch is solved.

Description

technical field [0001] The invention relates to the technical field of timepieces, and more specifically, to a watch movement. Background technique [0002] At present, there are generally only two types of clocks on the market: one is mechanical clocks, and the other is quartz electronic clocks. Among them, mechanical clocks and watches have exquisite craftsmanship. The continuous swing of the balance wheel and the continuous beating of the second hand allow users to experience the passage of time. It is difficult to process. The balance wheel in mechanical clocks and watches is a component with high size requirements and strict weight control, and the processing accuracy is high. It is difficult to ensure the consistency of each part through machining, the qualified rate of parts is low, and the processing cost is high; the balance wheel The pendulum tip on the component is easily broken after being subjected to vibration. In addition, in the higher-end tourbillon movem...
