Description
Technical field
The present invention relates to a kind of watch parts, and in particular to a kind of external tooth planet gear type changement of automatic watch.
Background technology
Automatic watch realizes watch power and comes from self-energy, and key therein is provided with self wind function.
It realizes self wind function, needs that changement is arranged between the pendulum mechanism of automatic watch and former dynamic system, pendulum is double
It is clockwork spring unidirectional tightened-up on power to yearn for physical pendulum turn to turn to former move.Currently, automatic watch changement generally using surpass from
Box-like changement is bored, reverse wheel is by pendulum as shown in Fig. 6 using multiple rollers between reverse wheel and reversing shaft axle sleeve
It drives, a steering makes roller drill chuck enter small end in petal slot, and reverse wheel and non-return ratchet and reversing shaft axle sleeve solid lock are integrated
Rotation, and in another steering of reverse wheel, roller bores small end in abjection petal slot, and reversing shaft is made to be detached from the reverse wheel of rotation.
The mechanism is to force reversing shaft only to make Unidirectional by the fashionable friction lock clamp force of roller drill chuck, larger there are being worn between component
The technical issues of, roller can be caused to bore in a short time and increased with the fit clearance of reverse wheel and reversing shaft shaft room, work is caused
It is greatly attenuated as reliability, or even commutation work is made to fail.
Invention content
The present invention provides a kind of external tooth planet gear type changement of automatic watch, and functional reliability is high, and torque is transmitted flat
Surely, upper string efficiency automatically is improved；It is compact-sized, it is highly suitable for slim automatic watch.
Technical scheme is as follows：
A kind of external tooth planet gear type changement of automatic watch, including commutation tooth shaft, change wheel slice, commutation ratchet, only
Inverse ratchet and two planetary gears, commutation tooth shaft are arranged axis platform one, axis platform two and axis platform three, two protruding shafts are arranged on change wheel slice,
The planetary gear is mounted in the protruding shaft, and change wheel slice is mounted in axis platform one, and commutation ratchet is mounted in axis platform two, commutation
The tooth of ratchet and the tooth of the planetary gear overlap, and non-return ratchet is mounted in axis platform three.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are that change wheel slice is with axis platform one
Clearance fit.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are that commutation ratchet is with axis platform two
Clearance fit.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are that non-return ratchet is with axis platform three
Interference fit.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are that the planetary gear can be around described
Protruding shaft is freely rotated.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are non-return ratchet and change wheel slice
Axial gap be 0.22~0.24mm.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are that the planetary gear is equipped with 6
Tooth.
The external tooth planet gear type changement of the automatic watch, preferred embodiment are that commutation ratchet c is equipped with 13
Tooth.
Beneficial effects of the present invention are：The present invention relative to super-clutch type changement, eliminate roller bore and
The structure that the dynamic driving of one-way lock for generating friction lock clamp force is bored by roller, overcomes and wears big and fit clearance is caused to increase, very
To cause cooperation fail the technical issues of instead the relatively reliable external tooth planet gear type of structure commutating structure,
Advantage is no spring, transmits torque in one direction, another direction does not stress then, and idle running angle is smaller, is winded up efficient, torque
It transmits steady；Movement thickness containing the present invention increases few, compact-sized, reliable operation, suitable for manufacturing slim automatic machine
Core.

Specific implementation mode
As shown in Figures 1 to 3, the external tooth planet gear type changement of a kind of automatic watch, including commutation tooth shaft 2, reverse wheel
Axis platform 1, axis platform 28 and axis platform 39 is arranged in piece 1, commutation ratchet 3, non-return ratchet 5 and two planetary gears 4, commutation tooth shaft 2；It changes
It is φ 4.284mm, thickness 0.25mm to wheel 1 outer diameter of piece, is symmetrical arranged the protruding shaft 6 of two φ 0.3 on change wheel slice 1, two
6 centre-to-centre spacing of protruding shaft is 2.66mm；4 outer diameter of the planetary gear is φ 1.012mm, thickness 0.18mm, and the planetary gear 4 is mounted on
In the protruding shaft 6, the planetary gear 4 can be freely rotated around the protruding shaft 6；Change wheel slice 1 is mounted in axis platform 1, reverse wheel
Piece 1 is clearance fit with axis platform 1；3 outer diameter of ratchet that commutates is φ 1.987mm, thickness 0.25mm, and commutation ratchet 3 is mounted on
In axis platform 28, commutation ratchet 3 is clearance fit with axis platform 28；The planetary gear 4 is equipped with 6 teeth, and commutation ratchet 3 is equipped with 13
The tooth of tooth, the tooth and the planetary gear 4 of the ratchet 3 that commutates overlaps；Non-return ratchet 5 is mounted in axis platform 39；Non-return ratchet
5 with axis platform 39 be interference fit；Non-return ratchet 5 and the axial gap of change wheel slice 1 are 0.24mm, to ensure two planetary gears 4
There is suitable axial gap with commutation ratchet 3, it is ensured that being capable of flexible rotating when its work.
The external tooth planet gear type changement specific work process of above-mentioned automatic watch is as follows：Automatic watch wear when with
The movement of arm, autoplugger does clockwise and rotates counterclockwise, and power passes to change wheel slice 1 by gear drive, such as Fig. 4 institutes
Show：When change wheel slice 1 rotates clockwise, start in a flash, planetary gear 4 revolves round the sun clockwise with change wheel slice 1, while around convex
6 rotation clockwise of axis；First tooth of one of planetary gear 4 is in contact with first tooth of commutation ratchet 3, as rotation should
Second tooth of planetary gear 4 and second tooth of commutation ratchet 3 mutually push up, and by commutation 3 top pressure of ratchet in commutation tooth shaft 2, rely on
The frictional force to commutate between ratchet 3 and the tooth shaft 2 that commutates, change wheel slice 1 drive commutation ratchet 3 to rotate clockwise, at this time the planet
Wheel 4 stops rotation, at the same time commutation tooth shaft 2 and non-return ratchet 5 is driven also to rotate clockwise, and realizes that movement winds up automatically.Such as
Shown in Fig. 5：When change wheel slice 1 rotates counterclockwise, planetary gear 4 then when revolution counterclockwise along commutation 3 helical teeth of ratchet around
Rotation that protruding shaft is counterclockwise does not apply pressure to commutation ratchet 3, the relationship in movement does not occur with commutation tooth shaft 2, at this point, commutation
Piece 1 is taken turns to dally.
