Abstract
The invention relates to a timer spring having high precision time-travelling. According to the invention, a cover casing and a pedestal compose a housing of a timer; a spring 8 is arranged in the housing and is connected with a first wheel 7, a second wheel 6, a third wheel 5 and a fourth wheel 4 so as to realize acceleration, time is controlled by releasing an escape wheel 3 and a balance wheel 2, and timing control is carried out by disconnecting or connecting a lever 9, a cam 12, a disconnecting and connecting seat 13, a movable contact spring 14 and a static contact spring 15. Compared to the prior art, the invention is characterized in that the spring is no longer of a same thickness, and the thickness of the spring is increasingly thinner from head to end instead; therefore, when the spring is wound up or loosened in winding, the spring has a constant active force on gears, thereby improving time-travelling precision of the timer.
Description
Technical field
The present invention relates to a kind of clockwork spring, especially relate to the high timer clockwork spring of a kind of timekeeping performance.
Background technology
Timer inside mainly comprises three parts: first is a power part: be made up of clockwork spring, the unidirectional mechanism that winds up, clockwork spring provides the power of total system.Second portion is a release portion: by one group of speed gear, escape wheel is formed, the power output that balanced release clockwork spring provides.Third part is a timing springing unit, makes in the gear set certain gear forward certain angle to and sends a mechanical signal, the control break-make.
The thickness of existing clockwork spring whole piece is all the same; When rolling-in or volume pine, clockwork spring will be different to the acting force of gear, and the timekeeping performance of timer receives the influence of clockwork spring power output; The clockwork spring that whole piece thickness is all the same has so just influenced the speed that gear rotates, and causes the timer timekeeping performance to reduce.
Summary of the invention
The object of the invention is exactly in order to overcome existing clockwork spring in rolling-in weak point first big after small to the gear power output during to the volume pine, to provide a kind of output torque more constant clockwork spring, be applied in timer, reaching the purpose of raising timekeeping performance.
The present invention forms the housing of timer by case and base, clockwork spring 8 is housed in the shell is connecting great wheel 7, two and take turns 6, three-wheel 5; Four-wheel 4 is realized speedup, discharges the control time through escape wheel 3 escapements 2, through lever 9; Cam 12, the disconnected seat 13 that closes, movable contact spring 14 carries out timing controlled with static contact spring piece 15 disconnected closing.
Because the precision the when output torque of the escape wheel of timer size influences timer travel; And escape wheel moment size is the influence that receives the clockwork spring output torque; The clockwork spring output torque receives the influence of length and width, thickness and the elasticity modulus of materials of clockwork spring, so the present invention adopts a kind of like this clockwork spring: its thickness from top to the end gradually by thick to thin, reach clockwork spring when rolling-in or volume pine; To the more constant purpose of gearing force rate, thereby improve the timer timekeeping performance.
Fig. 1, Fig. 2 are the structural representations of the embodiment of the invention.
Fig. 1 representes structure member, and Fig. 2 representes the flip flop equipment of timer.
Label among the figure is that 1-case, 2-escapement, 3-escape wheel, 4-four-wheel, 5-three-wheel, 6-two are taken turns, 7-great wheel, 8-clockwork spring, 9-lever, 10-base, 11-main shaft, 12-cam, disconnected seat, 14-movable contact spring, the 15-static contact spring piece of closing of 13-
Embodiment
Below in conjunction with accompanying drawing and embodiment invention is described further:
As shown in the figure, form the housing of timer by case 1 and base 10, clockwork spring 8 is housed in the shell is connecting great wheel 7; Two take turns 6, three-wheel 5, and four-wheel 4 is realized speedup; Discharge the control time through escape wheel 3 escapements 2, through lever 9, cam 12; The disconnected seat 13 that closes, movable contact spring 14 carries out timing controlled with static contact spring piece 15 disconnected closing.Described clockwork spring 8 thickness from top to the end gradually by thick to thin.No matter clockwork spring 8 reaches the purpose that improves the timer timekeeping performance more constant to the gear set power output when rolling-in or volume pine like this.
