Embodiment
Below in conjunction with drawings and Examples, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
As everyone knows, the serviceable life of wrist-watch and timekeeping performance are two principal elements passing judgment on wrist-watch quality, from serviceable life, use different cassette mechanism can affect the length in its life-span, and when making movement, clamping plate as support timepiece movement requisite device, material select and structure design on all can affect serviceable life of whole wrist-watch; From timekeeping performance, stem-winder error is large compared with quartz watch, General Influence stem-winder timekeeping performance because have:
(1) external environmental factor.Solution: aseismatic design, waterproofing design, antimagnetic design, supplementary protection shell etc.
(2) friction factor of transmission bar is large.Solution: improve lubricating condition, according to different requirements, selects different lubricating oil; Adopt jewel bearing or pad; Improve the flank of tooth condition of gear, comprise the conjugate tooth profile of employing science and improve surface smoothness etc., but the general flank of tooth is unlubricated.
(3) index lever is a kind of economic structure when being convenient to school, but theory and practice all confirms that its can the tautochronism of influential system, and also may produce potential difference, these timing error randomnesss are larger, cannot compensate or offset.Solution: as far as possible reduce inside and outside index lever spacing; But best bet does not have index lever, regulate speed, as the Mircro stella regulating system of Rolex company by regulating the inertia of escapement.
(4) impact of escapement mainly in energy transfer process on the impact that balance and hair spring system produces, balance and hair spring system is only when freely shaking, could maintain fixing concussion frequency, obviously, the energy transfer process of escapement can affect concussion frequency.Theory shows, when transmittance process is close to escapement equilibrium point, this impact can reduce.Solution: adopt accurate escapement, as claw escapement, its energy transfer process occurs near equilibrium point, the angle passing punching is also very little, affect also smaller, and its unidirectional biography punching make balance and hair spring system have more freely to shake space.
(5) impact of temperature is mainly manifested in two aspects: first, temperature variation can change the active length of hairspring, changes the inertia of escapement simultaneously, directly can have influence on accuracy of timekeeping; Secondly, temperature variation can affect oil body, affects transmission efficiency, thus affects timing.Solution: adopt opening bi-metal temperature compensating ablancer hair spring system; Adopt specific alloy material to make hairspring and escapement, make it there is certain temperature compensation in working temperature district; Adopt the temperature compensation of moving speed pin.
Except above-mentioned 5 factors affect except timekeeping performance, also have the influence factors such as magnetic field, hairspring balance, escapement balance.And the timekeeping performance of quartz watch is mainly because the decline of quartz oscillation causes, relative
accuracydecrease, external factor is the same with the influence factor of stem-winder, such as: vibrations, water inlet, magnetic field, without shell protection, temperature etc.
