But, due to two driving wheel on barrel one the first from left right arrange, the third wheel increased therebetween has tied up the position of centre wheel, and therefore centre wheel is forced down to move position, and the diameter of movement the most just requires bigger.In the pocket-watch epoch, double going barrels chain on the 8th has been made the most thick and heavy huge, has arrived the wrist-watch epoch, movement is required to be made small and exquisite frivolous, but double going barrel parallel technologies are difficult to accomplish that movement is frivolous small and exquisite, at existing long power movement, double going barrel parallel connections are lost ground gradually.

And another kind of double going barrel serial connection technology is increasingly becoming design main flow, the advantage of double going barrels series connection is: double going barrels and each travelling gear, layout that can be the compactest, takes full advantage of the space in timepiece movement, and movement can be made small and exquisite.But the inferior position of double going barrels series connection is: the power of first driving wheel on barrel is transferred to second driving wheel on barrel, screwed the clockwork spring of second barrel by first driving wheel on barrel after, again by second driving wheel on barrel transmission to third wheel and centre wheel, between two driving wheel on barrels, power in-fighting is big, equilibrium is owed before and after power, the decay of later stage power is many, and third wheel to bear the lateral pressure increasing suddenly nearly several times, makes the pressure of wheel shaft side and abrasion increase.

Need a kind of train arrangement compact and reasonable, double going barrel parallel connection movements that volume is smaller and more exquisite the most in the market.

Utility model content

Technical problem to be solved in the utility model is that existing pair of going barrel parallel machine core volume is excessive, the problem that train arrangement is the compactest.

In order to solve above-mentioned technical problem, this utility model be employed technical scheme comprise that the drive mechanism providing a kind of pair of going barrel parallel connection timepiece movement, include two going barrel wheels being set up in parallel successively, and shape is the first third wheel of second order gear, second third wheel and centre wheel, the center of movement is located in the axle center of described first third wheel, the tooth axle both sides of described first third wheel are engaged with two described going barrel wheels respectively, the wheel sheet of described first third wheel engages with the tooth axle of described second third wheel, the wheel sheet of described second third wheel engages with the tooth axle of described centre wheel, described centre wheel is coaxially disposed with described first third wheel, the wheel sheet of described centre wheel and three-wheel, second wheel and escape wheel engage linkage successively.

In such scheme, the wheel shaft of described first third wheel is the tube axle with through hole, and the tooth axle of described centre wheel is arranged in the wheel shaft of described first third wheel, and described first third wheel and described centre wheel are individually fixed between two laminated planks.

This utility model, the first third wheel and centre wheel the two is made to account for very much the gear overlap of plane space, two gears only account for the plane space of a gear, save the biggest plane space, centre wheel the most down moves position, and movement diameter can be made smaller and more exquisite, and the layout of train is the compactest, reasonable and attractive in appearance, and also remain the advantage that double going barrel is in parallel, there is advantage energy-conservation, that power output is powerful, power is stable and wear-resistant before and after exporting.
