Specific embodiment
Embodiment 1, a kind of high speed interval movement device of being made up of gear rack comprise disk 1, gear 2, tooth bar 3; Wherein:
The cam rail 7 of arc and the tooth bar 3 of arc all are fixed on the disk 1; The destination county of the cam rail 7 of arc is provided with flex point 8 and is connected with the starting point of the tooth bar 3 of arc; The starting point of the cam rail 7 of arc is connected with the terminal point of the tooth bar 3 of arc;
Rotate in the cam rail that is stuck in disk 17 of thumb wheel 4 activities of gear 2 and slide, fluted disc 5 activities of gear 2 with tooth bar 3 engagement.
The method of work of embodiment 2, a kind of high speed interval movement mechanism device of forming by gear rack, wherein:
The cam rail 7 of arc and the tooth bar 3 of arc all are fixed on the disk 1; The destination county of the cam rail 7 of arc is provided with flex point 8 and is connected with the starting point of the tooth bar 3 of arc; The starting point of the cam rail 7 of arc is connected with the terminal point of the tooth bar 3 of arc;
When gear 2 and cam rail 7 do relative motion in the flex point 8 that the destination county that enters cam rail 7 is provided with, cam rail 7 curvature change, driven gear 2 breaks away from cam rail 7 under certain rotational velocity, the fluted disc 5 and the tooth bar 3 of gear 2 enter engagement, disk 1 drives tooth bar 3 rotations, tooth bar 3 continues fluted disc 5 rotations of driven gear 2, and fluted disc 5 is the central shaft of actuation gear 2 again;
Working principle: when gear 2 broke away from engagement with tooth bar 3, because of the central shaft of external power source driver plate 1, by above-mentioned transmission, the central shaft of gear 2 can drive external mechanical part by axle.
When entering in the cam rail 7 when gear 2 breaks away from engagements with tooth bar 3, the central shaft of fluted disc 5, gear 2 all is in drive condition at out-of-work intermittence.
Because hocketing of above-mentioned two kinds of working staties finished two kinds of work that intermittence and rotation drive.
Because the axle power that is hit in the centre of motion of the present utility model is less, be more suitable under high speed, carrying out intermittent movement than the ratchet and pawl arrangement of routine.
The method of work of embodiment 3, a kind of high speed interval movement mechanism device of forming by gear rack, wherein: gear 2 is by thumb wheel 4, and parts 6 and fluted disc 5 three-deckers are formed in the gear; Thumb wheel 4 is arranged in the edge of a side of gear parts 6, and fluted disc 5 is arranged in the opposite side of gear parts 6, and parts 6 are coaxial in fluted disc 5 and the gear; The cam rail 7 of arc and the tooth bar 3 of arc all are fixed on the disk 1; The destination county of the cam rail 7 of arc is provided with flex point 8 and is connected with the starting point of the tooth bar 3 of arc; The starting point of the cam rail 7 of arc is connected with the terminal point of the tooth bar 3 of arc; Thumb wheel 4 with gear 2 is stuck in the cam rail 7 of disk 1 earlier; Disk 1 usefulness locking member is fixed, forbidden that disk 1 rotates; The central shaft of external power source actuation gear 2 is done the planet wheel motion around the central shaft of disk 1, and the thumb wheel 4 of gear 2 slides at cam rail 7; When gear 2 and cam rail 7 do relative motion in the flex point 8 that the destination county that enters cam rail 7 is provided with, cam rail 7 curvature change, gear 2 breaks away from cam rail 7 under certain rotational velocity, the fluted disc 5 and the tooth bar 3 of gear 2 enter engagement, fluted disc 5 is done relative rotary motion with tooth bar 3, and fluted disc 5 is the central shaft of actuation gear 2 again; Gear 2 moves to the terminal point of the tooth bar 3 of arc, and fluted disc 5 breaks away from engagement with tooth bar 3, and just in time facing to cam rail 7, gear 2 enters in the cam rail 7 thumb wheel 4 of gear 2 again; Finish an operation cycle.
Concrete application 1:
The central shaft of external power source driver plate 1, the central shaft axle of gear 2 drive the dialing parts of the automatic dialer in the seal paper money field, finish at a high speed the intermittently task of dialing.
Concrete application 2:
Disk 1 usefulness locking member is fixed, forbidden that disk 1 rotates; Enable the central shaft of external power source actuation gear 2 and do the planet wheel motion around the central shaft of disk 1, the central shaft of gear 2 drives the dialing parts of the automatic dialer in the seal paper money field again with axle, finish at a high speed the intermittently task of dialing.
The Chinese patent that the technology that automatic dialer relates to can be declared with reference to Nanchang Banknote Printing Plant or Chinese coinage parent company.
During automatic dialer in seal paper money field was used, dialing itself need be used intermittent motion mechanism's device automatically, and the high-speed and stability of seal paper money field printing requires high than traditional printing field.So the high speed interval movement method of work there is special demand.
Adopt high speed interval movement method of work of the present utility model to improve more than 2 times than the working efficiency of the low speed intermittent movement of traditional ratchet and pawl arrangement.
