Description
Technical field
The present invention relates to that a kind of watch and clock movement is anodontia hinders clutch idler wheel mechanism, be applied on watch and clock movement.
Background technology
As shown in Figure 1, existing pointer quartz clock and watch movement many employings pull-out piece on the market, arbor drives trip(ping) lever, when trip(ping) lever drives third wheel clutch structure to carry out timing school.Because it exists third wheel clutch structure, so gear can exist the phenomenon that third wheel and minute wheel two peak contact clash, collide, make the work of movement unreliable, Yi Yinzha tooth and cause and stop slow table, such that movement failure rate is high, maintenance difficulties is high.Therefore provide a kind of watch and clock movement anodontia hinder clutch idler wheel mechanism oneself become when business urgently.
Summary of the invention
Under overcoming existing pointer quartz clock and watch movement timing state, push-and-pull arbor, arbor drives trip(ping) lever, trip(ping) lever drives the tooth that causes in the clutch process of third wheel to hinder causing trouble bad product phenomenon, the invention provides that a kind of watch and clock movement is anodontia hinders clutch idler wheel mechanism, there is structure ingenious, do not hinder tooth, do not affect transmission accuracy, movement can be improved without the need to too high manufacturing accuracy and can improve the advantage such as quality and dependability.
Technical scheme of the present invention is as follows:
A kind of watch and clock movement is anodontia hinders clutch idler wheel mechanism, comprises the arbor, trip(ping) lever, third wheel, transmission wheel, back gear, minute wheel and the hour wheel that are installed on respectively on movement housing; Described transmission wheel, back gear, minute wheel and hour wheel connection for transmission successively; Described arbor can move axially relative to movement housing and rotate, and when arbor axially outwards moves to timing working position, arbor the inner is connected with transmission wheel coaxial drive, when arbor axis be moved into normally walk time working position time, arbor the inner to depart from transmission wheel and is connected; Middle part and the movement housing of described trip(ping) lever are articulated and connected, described third wheel is rotationally connected with one end of trip(ping) lever, the other end of described trip(ping) lever is connected with arbor the inner, and this link can drive trip(ping) lever to rotate around pin joint when arbor moves axially, and then third wheel is driven to realize engaging or disengaged condition with minute wheel; Described third wheel periphery is provided with around circumference alternatively distributed long tooth and short tooth at equal intervals, and the ad. of described long tooth is greater than short tooth.
The third wheel teeth size of existing third wheel mechanism is all the same, and therefore it is engaging with minute wheel or is easily hitting tooth in disconnecting process and touch tooth phenomenon.Third wheel after the application's improvement has the length tooth of alternate intervals distribution successively.Tooth spoke subtended angle a, the third wheel teeth of the application are made up of short tooth and long tooth, short tooth is compared long tooth and is reduced and rise S, thus compared to existing technology in the design of the little tooth of isometric third wheel, the arc length P of original adjacent two between cog is reduced to T, creates drift angle difference θ (this drift angle difference θ is original adjacent two tooth tooth top lines and the angle improveing rear adjacent long tooth and short tooth tooth top line).When third wheel engages with minute wheel, the long tooth of third wheel is introduced into the engagement of minute wheel teeth, short tooth enters the teeth engagement at interval more afterwards, avoid two pairs of teeth offset cause tooth wound, effectively prevent and to engage with minute wheel or hitting of disconnecting process touches tooth phenomenon, reduce failure rate and the maintenance cost of movement gear.
The drift angle difference θ of described long tooth and short tooth is 5-10 °.Hitting of third wheel and minute wheel can be touched tooth rate and drop to minimum by the design of this angle.
Described transmission wheel and arbor are coaxially socketed, described back gear and transmission wheel engaged transmission, described back gear and minute wheel engaged transmission, described minute wheel and hour wheel coaxial linkage.
Described trip(ping) lever is provided with the signal collection and the transmitter that to engage with minute wheel for collecting and send third wheel and throw off situation information, and the information collected wirelessly can be sent to external message handler by this signal collection and transmitter.The design achieves the effective monitoring to third wheel and minute wheel working condition, can safeguard clock and watch in the very first time, effectively reduce the damaged condition of clock and watch.
Compared with prior art, the present patent application has the following advantages:
1) design of third wheel is spaced apart successively length tooth, effectively prevent and to engage with minute wheel or hitting of disconnecting process touches tooth phenomenon, reduce failure rate and the maintenance cost of movement gear;
2) design of the drift angle difference θ of the long tooth of third wheel and short tooth 5-10 °, touches tooth rate drop to minimum by hitting of third wheel and minute wheel.
3) setting of signal collection and transmitter on trip(ping) lever, facilitates the timely maintenance of clock and watch.
