Description
Technical field
The present invention relates to a kind of movement, more particularly to a kind of watch and clock movement.
Background technology
The general hour hands of large-scale desk clock or turret clock and minute hand have larger weight, therefore do not require nothing more than and provide rational hour hands
With the supporting structure of minute hand, and the larger torque for the operation for driving hour hands and minute hand is provided.Cassette mechanism structure common at present
It is as follows to still have problem：First, complete that definite its number of steps of speeds of gear ratio is few, and transmission mechanisms at different levels bear larger load,
Each parts discontinuity equalization, carrying torque is smaller, influences the service life of movement；Second, for hour hands and minute hand support arm end compared with
Short, the overhanging end of hour hands and minute hand is relatively long, and axis and split axle occur bending and deformation when being easy to cause.
The content of the invention
The present invention is in view of the deficiency of the prior art, there is provided and a kind of mechanism size is smaller, carrying torque is larger, and
The watch and clock movement of each parts stress equalization.
Heretofore described is front and rear, is that watch and clock movement is in hour hands and minute hand using the hour hands of clock and watch, minute hand mounting surface before
Rear side；
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of watch and clock movement, including housing, further include snail
Wheel, worm screw, split axle, when axis, center sun gear, fixed gear and planetary wheel carrier, the fixed gear fixes on the housing
And gap package, when described outside axis, the split axle is installed in the housing and stretches out outside the housing, institute along the longitudinal direction
State that to be set with the worm gear, the center sun gear, planetary wheel carrier arranged on worm gear front end on split axle successively from back to front timely
Axis；
The rear end of the planetary wheel carrier is provided with branch's star-wheel, and planetary gear when front end is provided with, the rear end of axis is set when described
There is hour wheel, planetary gear is meshed at the same time with the hour wheel and the fixed gear when described；

The inner circle of the housing is equipped with ring gear corresponding with plane where the center sun gear, and the ring gear is consolidated
It is scheduled in the housing, branch's star-wheel is meshed at the same time with the ring gear and center sun gear；
On the housing, the worm screw is meshed with the worm gear, and one end of the worm screw is equipped with for the worm screw installation
Drive motor.
The beneficial effects of the invention are as follows：Using multi-stage speed-changing structure, when completing identical gear ratio, components at different levels are born
Balance in power, meanwhile, the combined use of the timely planet gear transmission of branch's planet gearing, complete machine can provide larger moment of torsion, movement
Service life is grown, compact-sized.
Based on the above technical solutions, the present invention can also be improved as follows.
Further, branch's star-wheel includes 2 or 3, and branch's star-wheel is centered on the center sun gear
It is uniformly distributed.
Further, when described planetary gear include 2 or 3, and it is described when planetary gear centered on the fixed gear
Even distribution, the fixed gear are external toothing.
Further, axis is supported on outside the split axle by axle bearing when first when described, and passes through axle bearing branch when second
Support in the housing, the split axle front-end and back-end are respectively by the first split axle bearing and the second split axle bearings when described
In axis and housing rear end.
Further, the center sun gear and the worm gear are in integrative-structure, pass through sun gear bearing and worm-wheel shaft respectively
Hold and be supported on the split axle.
Further, the housing is in cylindrical structure, including leading portion and back segment, and it is straight that the diameter of the leading portion is less than the back segment
Footpath.
Further, axis stretches out the leading portion of the housing when described, the front end of axis when the split axle stretches out described.
It is using the above-mentioned further beneficial effect of technical solution：Minute hand is installed on split axle, for larger clock and watch, is divided
The weight of pin is larger, and the torque that two-part bearing is received is larger；Split axle and when axis front and back end support distances length (such as the first split axle bearing and
The distance between second split axle bearing is much larger than the length of split axle section of stretching out, and the split axle section of stretching out refers to axis when split axle stretches out
Part；When first axle bearing and when distance is much larger than between axle bearing when second axis section of stretching out length, axis section of stretching out when described
Axis stretches out the part of front housing section when referring to；Split axle section of stretching out and when axis section of stretching out on minute hand and hour hands are installed respectively), holding
When carrying greater weight hour hands and minute hand, axis will not occur bending and deformation, when hour hands are installed on axis, when the weight of hour hands is larger
When, when the torque received of bearing it is larger when housing is equipped with leading portion, axis plays certain supporting role during leading portion pair, axis during increase
Carry torque, and when axis certain supporting role is played to split axle, add the carrying torque of split axle.
Further, the front end of the housing, rear end are respectively equipped with drive end bearing bracket, rear end cap with timely shaft end with timely axis front end
Lid, drive end bearing bracket and when axis between, when hubcap and split axle between be equipped with dust seal.
It is using the above-mentioned further beneficial effect of technical solution：Prevent dust etc. from entering movement, prevent mill inside movement
Damage, ensures the accuracy of movement.
Further, axis and the hour wheel are integrally formed when described.
Further, the split axle with it is described when axis rotating ratio be 12:1 or 24:1；The center sun gear with it is described
