Description
Technical field
The utility model relates to a kind of timepiece movement, particularly a kind of novel watch movement with elastic lever mechanism and friction gearing tarry device.
Background technology
Existing timepiece movement part is many, the manufacturing process complexity, and the pin timing is dialled in inconvenience, thereby needs innovation to improve.
Summary of the invention
The purpose of this utility model is intended to overcome the deficiencies in the prior art and provides a kind of simple in structure, parts machining process is realized easily, assembly process process is good, dials the convenient and reliable novel watch movement with elastic lever mechanism and friction gearing tarry device of pin timing function.
The purpose of this utility model is achieved in that
A kind of novel watch movement with elastic lever mechanism and friction gearing tarry device comprises rotor 01, power wheel 02, second wheel 03, third wheel 04, minute wheel 05, back gear 06, hour wheel 07, transmission wheel 09, push-and-pull arbor 08 ends a second post G1, elastic lever 31, bottom plate 51, train wheel bridge 52, train and friction gearing tarry device that positive plate 41 is formed also comprise supported hole 314 that third wheel 04 in the gear transmission chain is set on the elastic lever 31 and the pilot hole 318 that rotates around bottom plate reference column 518; Also be provided with the elasticity curved boom 311 and elasticity positioning head 312 that play the role of positioning; Transmission wheel 09 cooperates with the endoporus 091 of push-and-pull arbor 08 head 081; Positive plate 41 pilot holes 411 cooperate with the locating slot 082 and 083 of push-and-pull arbor 08 respectively, locate with group pin timing gear when having realized normally walking.By push-and-pull arbor 08, select different gears, when having realized normally walking with dial pin timing function.
Description of drawings
Fig. 1 and Fig. 2 are timepiece movement position (propelling arbor) when normally walking, elastic lever mechanism and friction gearing tarry device front view and expansion cut-open view.
Fig. 3 and Fig. 4 are that timepiece movement is being dialled pin timing position (pull-out piece), elastic lever mechanism and friction gearing tarry device front view and expansion cut-open view.
Embodiment
Be described further below by accompanying drawing and example the course of work elastic lever mechanism and friction gearing tarry device:
As Fig. 1～shown in Figure 2: positive plate 41 pilot holes 411 are stuck in 082 of push-and-pull arbor 08 locating slot, and elastic lever 31 pilot holes 318 are installed on the reference column 518 of bottom plate 51, and the third wheel 04 in the driving-chain is installed on the supported hole 314.Because 081 pair of elastic lever of push-and-pull arbor 08 head, 31 elasticity curved booms 311 have a side force, force elastic lever to rotate a certain angle around the reference column 518 of bottom plate 51, the third wheel 04 that is installed in like this on the elastic lever is in and second wheel 03 and minute wheel 05 position engaged, because only second, a post G1 broke away from elastic lever 31 and the wiring board, make stepper motor be in normal operating conditions simultaneously.When train realizes normally walking.
Its drive connection is: rotor 01 → power wheel 02 → second wheel 03 → third wheel 04 → minute wheel 05 → back gear 06 → hour wheel 07.
As Fig. 3～shown in Figure 4: when positive plate 41 pilot holes 411 are stuck in 083 of push-and-pull arbor 08 locating slot, arbor is removed the side force of elastic lever 31 curved booms 311, because 512 pairs of elastic levers of limiting stand, the 31 elasticity positioning heads 312 on the bottom plate have a pretension, under its effect, elastic lever is around reference column 518 revolutions of bottom plate 51, elastic lever 31 supported holes 314 oppositely produce displacement and drive the third wheel 04 generation inclination that is installed on the elastic lever 31, finishing third wheel 04 breaks away from minute wheel 05 engagement, driving-chain disconnects when walking, second hand high speed rotating when avoiding dialling the pin timing.Push-and-pull arbor 08 this time, head 081 and transmission wheel 09 endoporus 091 interference fit, when rotating push-and-pull arbor 08, friction force between push-and-pull arbor 08 head 081 and transmission wheel 09 endoporus 091 makes transmission wheel 09 rotate, transmission wheel drives the back gear 06 with its engagement, drive with the minute wheel 05 and the hour wheel 07 of its engagement by back gear 06 again and rotate, thereby realize dialling pin timing function.Simultaneously because elastic lever and control circuit board end a second post G1 contacts, make the stepper motor state that quits work, when movement stops to walk.
Its drive connection is: push-and-pull arbor 08 → transmission wheel 09 → back gear, 06 → minute wheel 05 and hour wheel 07.
