Description

The special-purpose movement of a kind of case clock

Technical field

The utility model relates to the movement that a kind of clock is used, the particularly a kind of 31 days special-purpose movements of case clock.

Background technology

31 days B that the existing machinery case clock uses ₂The type movement, by give the correct time mechanism and when walking mechanism form, the mechanism of giving the correct time still adopts the structure of original pendulum clock constant, comprises parts such as header wheel assembly, newspaper two wheel assemblies, newspaper tricycle assembly, newspaper four-wheel assembly, newspaper five wheel assemblies, wind wheel assembly; 31 days B that the existing machinery case clock uses ₂The type movement mainly is that mechanism improves during to the walking of former pendulum clock movement, and it is at the former national standard B of Ministry of Light Industry ₁When movement is walked on the basis of mechanism, gear structure changes ratio of gear to realize by changing, and mechanism comprises pallet module, escape wheel assembly, walks the four-wheel assembly, central axis component, center wheel assembly, center stage clip, walks two wheel assemblies, great wheel assembly, hour wheel module, crosses parts such as wheel assembly, minute hand, hour hands when walking.Great wheel assembly and header wheel assembly all contain great wheel box, great wheel sheet, and the great wheel sheet number of teeth is 86, and modulus is 0.75, and great wheel is 64.5 to the ratio of gear of central shaft, and great wheel box internal diameter is 55.4 _-0.29 ^-0.1, being provided with clockwork spring in the great wheel box, the clockwork spring width is 20.2 _-0.03Mm, thickness are 0.43 _-0.03Mm, clockwork spring are 11.4 circles, and length of run is 2900 _-33Mm; Great wheel assembly and header wheel assembly are all A=36.2mm with the axis hole centre distance of walking (newspaper) two wheel assemblies, in the great wheel planimetric position in movement front, are true origin O as if the axle hole with hour wheel module, and then header axle hole coordinate is X ₁=-35.722, Y ₁=-17.8, walking great wheel axis hole coordinate is X ₂=35.722, Y ₂=-17.8.Design at that time, main application are to design at the seat wall clock, and are applied to the case clock movement, and this design does not fundamentally solve the drawback that is short of power, and cause fate when the frequent reflection of consumer does not reach away over 20 years, and 31 days clock can only be walked about 26 days.

Summary of the invention

The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, and a kind of improved case clock movement is provided, the continuity that this movement can satisfy case clock when walking, and its reliable operation, cost is low.

For realizing above-mentioned purpose of the present utility model, the technical scheme that is adopted is: the special-purpose movement of a kind of case clock, comprise give the correct time mechanism and mechanism when walking, the mechanism of giving the correct time comprises the header wheel assembly, report two wheel assemblies, the newspaper tricycle assembly, newspaper four-wheel assembly, report five wheel assemblies, the wind wheel assembly, mechanism comprises pallet module when walking, the escape wheel assembly, walk the four-wheel assembly, central axis component, center wheel assembly, the center stage clip, walk two wheel assemblies, the great wheel assembly, hour wheel module, cross wheel assembly, the time needle assemblies, the great wheel assembly contains the great wheel sheet, the great wheel box, be provided with clockwork spring in the great wheel box, its design feature is that the great wheel sheet number of teeth is 87, and great wheel box internal diameter is 57.8 _-0.2 ^-0.1The length of run of clockwork spring is 3075 in the mm, great wheel box _-33Mm, the great wheel assembly is A=35.625mm with the axis hole centre distance of walking two wheel assemblies, in the great wheel planimetric position in movement front, is true origin as if the axle hole with hour wheel module, then header axle hole coordinate is X ₁=-36.2, Y ₁=-18, walking great wheel axis hole coordinate is X ₂=36.2, Y ₂=-18.

Most preferred embodiment of the present utility model is that the great wheel assembly of described movement is identical with the header wheel assembly, and the header wheel assembly is identical with the axis hole centre distance of walking two wheel assemblies with the axis hole centre distance and the great wheel assembly of newspaper two wheel assemblies, also is 35.625mm.

When movement is walked mechanism comprised pallet module, escape wheel assembly, walked the four-wheel assembly, central axis component, center wheel assembly, center stage clip, walk two wheel assemblies, great wheel assembly, hour wheel module, cross wheel assembly, the time needle assemblies, level Four speedup transmission by gear, the energy of great wheel assembly output is delivered to the escapement speed regulator by fixed drive ratio, thereby makes pendulum by the design cycle operate as normal.

When case clock movement operate as normal, central shaft relies on the elastic-friction of center wheel assembly and center making leaf spring to drive and rotates, and the minute hand of needle assemblies and hour hands carry out work when making.

Former B ₂The movement great wheel to the ratio of gear of central shaft is:

The utility model B ₆The movement great wheel to the ratio of gear of central shaft is:

$I=\frac{87}{8}\×\frac{60}{10}=65.25$

As can be seen from the above equation, great wheel is changeed 1 circle, and centre wheel can change 65.25 circles, because centre wheel and central shaft link together, minute hand is connected with central shaft again, so centre wheel changes 62.25 circles, just minute hand changes 65.25 circles, it is 1 hour that minute hand changes 1 circle, and promptly great wheel is changeed 1 circle, can walk 65.25 hours.

When wanting continuity and walking 31 days, great wheel (clockwork spring) number of effective coils n must reach:

$n=\frac{24\×31}{I}=\frac{24\×31}{65.25}=11.4$ Circle

Great wheel box inner diameter size is by original B ₂55.4 _-0.29 ^-0.1Become B greatly now ₆57.8 _-0.2 ^-0.1, former B ₂The clockwork spring width is 20.2 _-0.03, thickness is 0.43 _-0.03, length of run is 2900 _-33, the B after the improvement ₆Clockwork spring under the identical situation of former width, thickness, increases by a circle length, and its length of run is 3075 _-33The great wheel sheet number of teeth becomes 87 by 86, and modulus still is 0.75.Because the change of the great wheel sheet number of teeth, and make great wheel assembly and the axis hole centre distance of walking two wheel assemblies become A=35.625mm, in the great wheel planimetric position in movement front, if with the time needle assemblies axle hole be true origin O, the coordinate of header axle hole C becomes X ₁=-36.2, Y ₁=-18, the coordinate of walking great wheel axis hole B becomes X ₂=36.2, Y ₂=-18.

Through above-mentioned change, the number of effective coils of clockwork spring is 13.5 circles, greater than 11.4 circles, the increase of clockwork spring length has changed the ratio of gear of train, has improved the continuity when movement is walked, its reliable operation, cost is low, can drive diameter and be 180 pendulum operate as normal, through test repeatedly, be when walking more than 33 days, and can add calendar as required, manually end newspaper, table tennis time reporting function, not only be up to state standards 31 days, and movement is when walking more than perdurability to 33 day.

In order further to improve effect of the present utility model, the utility model adopts movement great wheel assembly identical with the header wheel assembly, and the header wheel assembly is identical with the axis hole centre distance of walking two wheel assemblies with the axis hole centre distance and the great wheel assembly of newspaper two wheel assemblies.
