Efficiency is low, or even failure.
Utility model content
Task of the present utility model is to provide for that a kind of wearability is good, intensity is high, the automatic watch for efficiency high of winding up
The hardware configuration of planet gear type changement.To achieve the above object, this patent adopts the following technical scheme that：
A kind of planet gear type changement of automatic watch, including automatic teeth portion part, from moving teeth axle, the first planetary gear,
Two planetary gears, hammer wheel, automatic winding wheel, change wheel slice and cover plate, first planetary gear are located at institute with second planetary gear
It is described to have axle platform one, axle platform two and the axle platform three that from top to bottom order is set from moving teeth axle in the plane for stating automatic teeth portion part,
The automatic teeth portion part is provided with two planetary gears and followed closely, and second planetary gear nails on installed in the planetary gear, and described the
Two planetary gears are freely rotated around planetary gear nail, and the automatic teeth portion part is arranged on the axle platform two, described from moving teeth
Part coordinates with the gap of axle platform two, and the hammer wheel engages with the automatic teeth portion part, first planetary gear, the cover plate
With the change wheel slice be arranged on the axle platform three on, first planetary gear, the cover plate and the change wheel slice with it is described
Axle platform three is interference fit, and the automatic up-regulation wheel engages with the axle platform one, the tooth of first planetary gear and described second
The tooth of planetary gear overlaps.
Using the planet gear type changement of automatic watch provided by the utility model, overcome abrasion and cause to coordinate greatly
Gap increases, even results in the technical problem for coordinating failure, the substitute is the commutation of the relatively reliable planet gear type of structure
Structure, its advantage are no springs, transmit torque in one direction, and another direction does not stress then, and idle running angle is smaller, upper string efficiency
Height, torque transmit steady, compact-sized, reliable operation, suitable for manufacture few containing movement thickness of the present utility model increase
Slim automatic movement.
Brief description of the drawings
Fig. 1 is the structural representation of the planet gear type changement of the utility model automatic watch；
Fig. 2 is the structural representation of the test tube sorting case of the planet gear type changement of the utility model automatic watch；
Wherein, automatic wheel component -1, the second planetary gear -2, cover plate -3, the first planetary gear -4, from moving teeth axle -5, axle platform one -
50, axle platform two -51, axle platform three -52, hammer wheel -6, automatic winding wheel -7, change wheel slice -8.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings, but protection model of the present utility model
Enclose the scope for being not limited to embodiment statement.
With reference to figure 1, a kind of planet gear type changement of automatic watch, including automatic wheel component 1, from moving teeth axle 5, first
Planetary gear 4, the second planetary gear 2, hammer wheel 6, automatic winding wheel 7, change wheel slice 8 and cover plate 3.
First planetary gear 4 is located at second planetary gear 2 in the plane of the automatic wheel component 1, described automatic
There are axle platform 1, axle platform 2 51 and the axle platform 3 52 that from top to bottom order is set, the axle platform 1, axle platform 2 51 on tooth axle 5
It is gradually reduced from top to bottom with the external diameter of axle platform 3 52, is arranged with two planetary gears nails on the automatic wheel component 1, described the
Two planetary gears 2 nail on installed in the planetary gear, and second planetary gear 2 freely rotates around planetary gear nail, described
Automatic wheel component 1 is arranged on the axle platform 2 51, and the automatic wheel component 1 coordinates with the gap of axle platform 2 51 so that institute
Automatic wheel component 1 to be stated to slide from moving teeth axle 5 is relative with described, the hammer wheel 6 engages with the automatic wheel component 1, and described first
Planetary gear 4 is provided with 13 teeth, and second planetary gear 2 is provided with 6 teeth, the tooth of first planetary gear 4 and second planet
The tooth of wheel 2 overlaps, and first planetary gear 4, the cover plate 3 and the change wheel slice 8 are arranged on the axle platform 3 52
On, first planetary gear 4, the cover plate 3 and the change wheel slice 8 are to be interference fitted with the axle platform 3 52, the cover plate 3
Between the change wheel slice 8 and first planetary gear 4, the cover plate 3 and the change wheel slice 8 are pressed on described automatic
On tooth axle 5, and overlay on first planetary gear 4, when first planetary gear 4 rotates, drive it is described from moving teeth axle 5,
The cover plate 3 and the change wheel slice 8 rotate.
The course of work of the planet gear type changement of the automatic watch is as follows：Automatic watch is when wearing with arm
Motion, autoplugger do clockwise and rotate counterclockwise, power passes to automatic wheel component 1 by gear drive, when automatic wheel portion
When part 1 rotates counterclockwise, the second planetary gear 2 revolves round the sun counterclockwise with automatic wheel component 1, while counterclockwise around planetary gear nail
Rotation；First tooth of one of them the second planetary gear 2 is in contact with first tooth of the first planetary gear 4, with rotation second
Second tooth of planetary gear 2 mutually pushes up with second tooth of the first planetary gear 4 so that the first planetary gear 4 can not have enough to meet the need, and then screens
First planetary gear 4 rotates together, realizes that movement winds up automatically, and wearability is good.When automatic wheel component 1 rotates clockwise, second
Rotationally clockwise, the second planetary gear 2 is when revolution clockwise along the helical teeth of the first planetary gear 4 around planetary gear for planetary gear 2
Rotation clockwise is followed closely, pressure is not applied to the first planetary gear 4, with the relation in motion does not occur from moving teeth axle 5, now, automatically
Wheel component 1 dallies, clockwise idle running, counterclockwise upper bar, so as to ensure to clockwork spring input power or single direction passing power
It is required that.
Above description is only the preferred embodiment of the application and the explanation to institute's application technology principle.People in the art
Member should be appreciated that utility model scope involved in the application, however it is not limited to what the particular combination of above-mentioned technical characteristic formed
Technical scheme, while should also cover in the case where not departing from utility model design, by above-mentioned technical characteristic or its be equal
Other technical schemes that feature is combined and formed.Such as features described above has with (but not limited to) disclosed herein
The technical scheme that the technical characteristic for having similar functions is replaced mutually and formed.
