Description
Technical field
This utility model relates to a kind of watch parts, is specifically related to the external tooth planet gear type reversing machine of a kind of automatic watch
Structure.
Background technology
Automatic watch achieves watch power and comes from self-energy, therein it is crucial that be provided with self wind function.
Self wind function to be realized, needs to arrange changement between the pendulum mechanism of automatic watch and former dynamic system, and pendulum is double
Being converted into former moving to reciprocally swinging is bar power on clockwork spring unidirectional tightened-up.At present, automatic watch changement commonly used surpass from
Box-like changement, as shown in Figure 6, utilizes the multiple rollers between reverse wheel and reversing shaft axle sleeve to bore, and reverse wheel is by pendulum
Driving, one turns to and makes roller drill chuck enter small end in petal groove, is admittedly locked with non-return ratchet and reversing shaft axle sleeve by reverse wheel and is integrated
Rotate, and in another of reverse wheel turns to, roller bores small end in abjection petal groove, makes reversing shaft depart from the reverse wheel rotated.
This mechanism is dependent on the fashionable friction lock clamp force of roller drill chuck forces reversing shaft only to make Unidirectional, exist wear and tear between parts bigger
Technical problem, roller can be caused at short notice to bore the fit clearance with reverse wheel and reversing shaft shaft room and to strengthen, cause work
It is greatly attenuated as reliability, even makes commutation work lose efficacy.
Utility model content
This utility model provides the external tooth planet gear type changement of a kind of automatic watch, and functional reliability is high, and moment passes
Pass steadily, improve upper string efficiency；Compact conformation, is highly suitable for slim automatic watch.
The technical solution of the utility model is as follows:
The external tooth planet gear type changement of a kind of automatic watch, including commutating tooth axle, change wheel slice, commutation ratchet, stops
Inverse ratchet and two planetary gears, commutating tooth axle arranges pillow block one, pillow block two and pillow block three, and change wheel slice arranges two protruding shafts,
Described planetary gear is arranged in described protruding shaft, and change wheel slice is arranged on pillow block one, and commutation ratchet is arranged on pillow block two, commutation
The tooth of ratchet overlaps with the tooth of described planetary gear, and non-return ratchet is arranged on pillow block three.
The external tooth planet gear type changement of described automatic watch, its preferred version is, change wheel slice with pillow block one is
Matched in clearance.
The external tooth planet gear type changement of described automatic watch, its preferred version is, commutation ratchet with pillow block two is
Matched in clearance.
The external tooth planet gear type changement of described automatic watch, its preferred version is, non-return ratchet with pillow block three is
Interference fit.
The external tooth planet gear type changement of described automatic watch, its preferred version is, described planetary gear can be around described
Protruding shaft is freely rotatable.
The external tooth planet gear type changement of described automatic watch, its preferred version is, non-return ratchet and change wheel slice
Axial gap be 0.22～0.24mm.
The external tooth planet gear type changement of described automatic watch, its preferred version is, described planetary gear is provided with 6
Tooth.
The external tooth planet gear type changement of described automatic watch, its preferred version is, commutation ratchet c is provided with 13
Tooth.
The beneficial effects of the utility model are: this utility model, relative to super-clutch type changement, eliminates rolling
Son bores and is moved the structure of driving by the one-way lock of roller brill generation friction lock clamp force, overcomes and weares and teares big and cause fit clearance
Strengthen, even result in the technical problem coordinating inefficacy, the substitute is the commutation of the relatively reliable external tooth planet gear type of structure
Structure, its advantage is not have spring, transmits moment in a direction, and another direction does not then stress, and idle running angle is less, upper string efficiency
Height, moment transmission is steadily；Increase few containing movement thickness of the present utility model, compact conformation, reliable operation, it is adaptable to manufacture
Slim automatic movement.

Detailed description of the invention
As shown in Figures 1 to 3, the external tooth planet gear type changement of a kind of automatic watch, including commutating tooth axle 2, reverse wheel
Sheet 1, commutation ratchet 3, non-return ratchet 5 and two planetary gears 4, commutating tooth axle 2 arranges pillow block 1, pillow block 28 and pillow block 39；Change
Being φ 4.284mm to wheel sheet 1 external diameter, thickness is 0.25mm, and change wheel slice 1 is symmetrical arranged the protruding shaft 6 of two φ 0.3, two
Protruding shaft 6 centre-to-centre spacing is 2.66mm；Described planetary gear 4 external diameter is φ 1.012mm, and thickness is 0.18mm, and described planetary gear 4 is arranged on
In described protruding shaft 6, described planetary gear 4 can be freely rotatable around described protruding shaft 6；Change wheel slice 1 is arranged on pillow block 1, reverse wheel
Sheet 1 and pillow block 1 are matched in clearance；Commutation ratchet 3 external diameter is φ 1.987mm, and thickness is 0.25mm, and commutation ratchet 3 is arranged on
On pillow block 28, commutation ratchet 3 and pillow block 28 are matched in clearance；Described planetary gear 4 is provided with 6 teeth, and commutation ratchet 3 is provided with 13
Tooth, the tooth of commutation ratchet 3 overlaps with the tooth of described planetary gear 4；Non-return ratchet 5 is arranged on pillow block 39；Non-return ratchet
5 with pillow block 39 be interference fit；Non-return ratchet 5 is 0.24mm with the axial gap of change wheel slice 1, to ensure two planetary gears 4
Suitable axial gap is had, it is ensured that can flexible rotating during its work with commutation ratchet 3.
The external tooth planet gear type changement specific works process of above-mentioned automatic watch is as follows: automatic watch when wearing with
The motion of arm, autoplugger does clockwise and rotates counterclockwise, and power passes to change wheel slice 1 by gear drive, such as Fig. 4 institute
Showing: when change wheel slice 1 rotates clockwise, starting in a flash, planetary gear 4 revolves round the sun clockwise along with change wheel slice 1, simultaneously around convex
Axle 6 rotation clockwise；First tooth of one of them planetary gear 4 contacts with first tooth of commutation ratchet 3, should along with rotating
Second tooth of planetary gear 4 pushes up mutually with second tooth of commutation ratchet 3, is pressed on commutating tooth axle 2 on commutation ratchet 3 top, relies on
Frictional force between commutation ratchet 3 and commutating tooth axle 2, change wheel slice 1 drives commutation ratchet 3 to rotate clockwise, now this planet
Wheel 4 stopping rotation, meanwhile drives commutating tooth axle 2 and non-return ratchet 5 also to rotate clockwise, it is achieved movement winds up automatically.As
Shown in Fig. 5: when change wheel slice 1 rotates counterclockwise, planetary gear 4 then one side counterclockwise revolution one side along commutation ratchet 3 helical teeth around
Rotation that protruding shaft is counterclockwise, does not applies pressure to commutation ratchet 3, the relation not moved with commutating tooth axle 2, now, and commutation
Wheel sheet 1 dallies.
