Embodiment
Below by the drawings and specific embodiments the utility model is described in further detail:
As shown in Figures 1 to 4, the utility model wrist-watch tandem driving mechanism comprises first driving mechanism and second driving mechanism; Described first driving mechanism comprises: first driving wheel on barrel 1, article one lid 2, article one axle 3, clockwork spring 4, yielding attachment 5; Described second driving mechanism comprises second driving wheel on barrel 6, second lid 7, second axle 8, clockwork spring 4, yielding attachment 5; Energy is exported to the wheel sheet 9 and the wheel shaft 10 of train.In described first driving mechanism, clockwork spring 4, yielding attachment 5 and article one axle 3 are put into first driving wheel on barrel 1 in regular turn, the direction of hook 1a and the curve precession direction of clockwork spring 4 are clockwise direction in first driving wheel on barrel, and it also is clockwise direction that the tip of the outer hook 3a of article one axle is pointed to; Article one, the upper and lower end of axle 3 passes the center pit of first driving wheel on barrel 1 and article one lid 2 respectively, the described article one lid 2 and first driving wheel on barrel 1 are pressed into one and article one axle 3 can rotate, and the inner of clockwork spring 4 has clockwork spring slotted hole 4a so clockwise direction to rotate article one axle 3 can to make the outer hook 3a of article one axle hook clockwork spring 4 and yielding attachment 5 will hook hook 1a in first driving wheel on barrel.In described second driving mechanism, clockwork spring 4, yielding attachment 5 and second axle 8 are put into second driving wheel on barrel 6 in regular turn, the curve precession direction of the direction of hook 6a and clockwork spring 4 is clockwise direction and the tip sensing of the outer hook 3a of second axle also is a clockwise direction in second driving wheel on barrel, the second lid 7 and second driving wheel on barrel 6 are pressed into one and second axle 8 is rotary, can make the outer hook 8a of second axle hook clockwork spring 4 and yielding attachment 5 will hook hook 6a in second driving wheel on barrel because the inner of clockwork spring 4 has clockwork spring slotted hole 4a so clockwise direction to rotate second axle 8.Hook 1a is opposite with hook 6a direction in second driving wheel on barrel in described first driving wheel on barrel.Yielding attachment 5 in described first driving wheel on barrel and second driving wheel on barrel is fixed on the clockwork spring 4 by spot welding, and is arranged on the clamping plate.Second driving mechanism passes wheel shaft 10 by the center pit of second axle 8, both can be combined together because second axle 8 individual square groove being arranged and wheel shaft 10 have individual square projection, and wheel sheet 9 is integral by riveted with wheel shaft 10, so second axle 8 can rotate with wheel shaft 10 by driven wheel sheet 9 when rotating; Second driving wheel on barrel 6 in first driving wheel on barrel 1 in described first driving system and second driving system is meshing with each other; Described first driving wheel on barrel 1, second driving wheel on barrel 6 are 1: 1: 1 with the ratio of gear of wheel sheet 9, therefore, wheel sheet 9 be the energy output wheel of the double driving system of tandem, and it will drive train and offer the vibrational system energy and keep its unattenuated vibration, and the drive correct demonstration time of indicating mechanism.
The course of work to the utility model wrist-watch tandem driving mechanism is illustrated below:
As depicted in figs. 1 and 2, the process of the double driving system of wrist-watch tandem mechanism storage power is: article one axle 3 is rotated in a clockwise direction, because the outer hook 3a of article one axle has hooked clockwork spring 4, thus when article one axle 3 is rotated in a clockwise direction when, will drive clockwork spring 4 together clockwise direction rotate and rolling-in clockwork spring 4 gradually.Because yielding attachment 5 is fixed on the clockwork spring 4 by spot welding and has hooked hook 1a in first driving wheel on barrel, therefore yielding attachment 5 will drive the rotation of first driving wheel on barrel, 1 clockwise direction when clockwork spring 4 clockwise direction are rotated rolling-in gradually.Because first driving wheel on barrel 1 and 6 engagements of second driving wheel on barrel, so the rotation of first driving wheel on barrel, 1 clockwise direction can drive second driving wheel on barrel 6 rotation counterclockwise.Because yielding attachment 5 is fixed on the clockwork spring 4 by spot welding and has hooked hook 6a in second driving wheel on barrel and the outer hook 8a of second axle has hooked clockwork spring 4, can drive in the time of second driving wheel on barrel 6 rotation counterclockwise therefore that yielding attachment 5 counterclockwise rotates and clockwork spring 4 also can counterclockwise rotate and rolling-in gradually.Along with article one axle 3 constantly clockwise direction rotate the clockwork spring 4 of the clockwork spring 4 of first driving system and second driving system will be by rolling-in.It should be noted that second driving system this moment rotating band driving wheel sheet 9 by second axle 8 in the process of rolling-in clockwork spring 4 has had a little energy to be released to pass to train makes vibrational system begin vibration.
As depicted in figs. 1 and 2, the process that the double driving system of wrist-watch tandem mechanism releases energy is: along with the clockwork spring 4 of the clockwork spring 4 of first driving system and second driving system by rolling-in, their energy will be released gradually.But, two driving systems are not to release energy simultaneously but second driving system mainly is responsible for energy (energy that comprised two driving system storages) that the clockwork spring 4 with rolling-in the discharges rotating band driving wheel sheet 9 by second axle 8 energy is exported to train, and play the effect to second driving system makeup energy during the output torque of first driving system to be output torque at second driving system be lower than first driving system.
When the output torque of second driving system during greater than the output torque of first driving system, the clockwork spring 4 of second driving system rolling-in begins to loosen and releases energy.Because so the outer hook 8a of second axle has hooked clockwork spring 4 when clockwork spring 4 loosens counter clockwise direction when rotating, so it can drive second axle 8 rotation counterclockwise and because second axle 8 has been combined together and has taken turns sheet 9 with wheel shaft 9 and has been integral second axle 8 meeting driven wheel sheets 9 and wheel shaft 10 rotation counterclockwise with wheel shaft 10 by riveted, by wheel sheet 9 energy of clockwork spring 4 releases of second driving system be exported to train.It should be noted that since this moment first driving system output torque less than the output torque of second driving system, so so it be motionless and because first driving wheel on barrel 1 meshes second driving wheel on barrel 6 with second driving wheel on barrel 6 also is motionless.
When the output torque of second driving system during less than the output torque of first driving system, the clockwork spring that first driving system begins to loosen rolling-in releases energy.Because clockwork spring 4 is one with yielding attachment 5, thus when clockwork spring 4 loosens yielding attachment 5 will drive the rotation of the first driving wheel on barrel clockwise direction and this moment article one axle 3 be motionless.Because first driving wheel on barrel 1 and 6 engagements of second driving wheel on barrel are counterclockwise rotated so the first driving wheel on barrel clockwise direction rotation can drive second driving wheel on barrel.Because yielding attachment 5 is logical to be fixed on the clockwork spring 4 and to have hooked hook 6a in second driving wheel on barrel, therefore when second driving wheel on barrel counterclockwise rotates and drives yielding attachment 5 rotation counterclockwise, can drive clockwork spring 4 rotation counterclockwise also gradually once more the clockwork spring that has loosened 4 of second driving system of rolling-in make the output torque rising of second driving system, so and first driving system compensates to the output torque reduction of second its clockwork spring of driving system, 4 rolling-in owing to the part energy with it, when the output torque of second driving system during once more greater than the output torque of first driving system, the clockwork spring 4 of its rolling-in loosens once more and releases energy and take turns sheet 9 by one and continue the energy that its discharges is exported to train, and this moment first driving system output torque again less than second driving system output torque, so it is slack once more.So because first driving wheel on barrel 1 and second driving wheel on barrel, 6 engagements, second driving wheel on barrel 6 also can be slack once more.
More than two kinds of situations can occur repeatedly, as long as the output torque of second driving system is less than the output torque of first driving system, first driving system energy supplement will be given second driving system up to the clockwork spring 4 of its rolling-in loosen fully do not have energy supplement to give second driving system till, the output torque of first driving system was close to zero and stopped operating this moment.Having only second driving system oneself to continue first driving system replenished also has its energy that oneself does not discharge to continue that logical setting pinion 9 is exported to train with the energy of its release for own energy and is two just double energy of energy that driving system is stored by the energy that second driving system exported, up to there not being releasable energy to export to train, when this moment, wrist-watch stopped to walk.
