Abstract
The invention belongs to a kind of counting assembly in two pointer discharge counters.Its counting mechanism comprises counting, centre, carry gear and ad hoc position-limited wheel and moving tooth plate; Neutral gear by length, the square tooth is alternate constitutes, and cooperates with position-limited wheel and moving tooth plate with a teeth groove, has both done transmission, make the Positioning Gear usefulness of carry gear again, thereby cancelled the pressure spring location.Therefore this device not only has high sensitivity and reliability, and overcome the employing spring positioning to install, debugging has relatively high expectations, assembly difficulty is big, production efficiency low and sensitivity and the relatively poor disadvantage of reliability.
Description
The invention belongs to a kind of counting assembly in the discharge counter, particularly a kind of double-pointer electromagnetic counter is suitable for the number of times that the record lightning arrester moves in discharge counter.
At notification number is CN2066629U, name is called in the utility model patent of " two pointer discharge counter ", disclose a kind of double-pointer electromagnetic counter, the gear set that is used to count in this device is made up of counting gear (driving gear), neutral gear, individual gears and carry gear (follower gear); On the carry gear, also adopted a pressure spring sheet to be located, preventing of the motion of this gear, and made the carry gear produce misoperation by the friction force between its gear shaft and the carry gear bush because of counting gear (driving gear).It is had only when individual gears and carry gearing mesh, and the resistance that just can overcome the retainer spring sheet drives the carry gear and the pointer that is fixed on this gear bush is done the carry motion.There are two main disadvantages in this kind structure, and first, must overcome the resistance of spring leaf during carry, thus influenced the sensitivity of counter carry; The second,, and require the sensitivity that improves carry as far as possible on the other hand owing on the one hand require counter can not produce misoperation.Therefore the debugging to pressure in the selection of spring leaf pressure and the assembling has just proposed higher requirement, thereby has both influenced the throughput rate of product, has influence on the reliability and the sensitivity of product quality again.
The objective of the invention is to design a kind of neutral gear that utilizes and both rotated, again the double-pointer electromagnetic counter that the carry gear is played the role of positioning.Overcome the disadvantage that adopts pressure spring sheet location to be brought, simplify assembling and debugged program, improve the purposes such as quality, sensitivity and production efficiency of product to reach.
Solution of the present invention is to set up a position-limited wheel and a moving tooth plate, both cooperations both can pass to the carry gear by neutral gear with the action cycle property ground of counting gear, can on request neutral gear be pinned again, thereby the carry gear be located by neutral gear; On position-limited wheel and moving tooth plate, a teeth groove is arranged respectively, the overlapping setting of two teeth groove and can with the neutral gear engaged transmission; In moving tooth plate teeth groove side is pusher dog; And neutral gear is long and short alternate cylindricality gear; The carry gear is placed on the counting gear axle sleeve versatilely by axle sleeve, the mutual interlock of its gear teeth and neutral gear; Position limited gear is positioned at the radial section of long tooth bottom and is fixed on the counting gear axle sleeve; The moving tooth plate is positioned at short tooth sagittal plane.Both can be fixed on the counting gear axle sleeve, also can be directly fixed on the position limited gear, counting gear then be positioned at position limited gear the below and with the shift fork interoperation; Whole device then is connected into one by fixed head and discharge counter.Counting gear is 10 teeth, and the carry gear is 2: 1 with the ratio of the counting gear number of teeth; The nominal size of position-limited wheel radius is identical with the carry gear; The number of teeth of neutral gear can be 6,8 or 10 teeth, and wherein long tooth both can be set to an integral body, also can be arranged to upper and lower two parts, and the pusher dog of moving tooth plate teeth groove side both can be monodactyle, also a pawl can respectively be set in both sides.
Because the neutral gear of this electromagnetic counter adopts long and short tooth columnar tooth structure alternately, and cooperate with position-limited wheel, moving tooth plate, both can finish the carry transmission, can position the carry gear again, thereby make this counting assembly not only have high sensitivity and reliability, and can simplify its assembling and debugged program greatly, boost productivity.Thereby it is big to have overcome the assembling, the debugging difficulty that adopt spring positioning to exist, and throughput rate is low, influences disadvantages such as the sensitivity of counting mechanism and reliability.
Fig. 1 is this apparatus structure synoptic diagram;
Fig. 2. be the I partial enlarged drawing;
Fig. 3. be the A-A view;
Fig. 4. be the B-B view;
Fig. 5. be counting gear, position limited gear and moving tooth plate structure and mutual relationship synoptic diagram;
Fig. 6,7 is respectively the left and right view of Fig. 5.
Among the figure: 1, be counting gear, 2, neutral gear, 3, the moving tooth plate, 4, position-limited wheel, 5, carry gear, 6, shift fork, 7, short pointer, 8, Long pointer, 9, reading dial, 10, attachment pegs, 11, fixed head, 12, solenoid, 13, shift fork armature, 14, pusher dog, 15, teeth groove, 16, short tooth, 17, long tooth, 18, the carry gear bush, 19, the counting gear axle sleeve.
Embodiment
Each gear and position-limited wheel 4 in the present embodiment, moving tooth plate 3 all adopts brass sheet to be stamped to form, thick 1mm; Counting gear 1, tooth number Z=10, radius of addendum R5mm; Carry gear 5, tooth number Z=20, modulus m=0.6, radius of addendum R6.6mm; The radius of gyration of moving tooth plate 3 also is 6.6mm, and present embodiment pusher dog 14 is two profile of tooth pusher dogs and teeth groove 15, modulus be m=0.6; Position-limited wheel 4, radius R 6.6mm, neutral gear 2, present embodiment are 8 teeth, radius of addendum R3.32mm lacks tooth 16, high 2.1mm, long tooth depth 3.1mm, modulus also is 0.6, the remainder of this electromagnetic counter is all same with prior art.
In the use, by the next dash current of lightning arrester, enter discharge counter, again through capacitor to solenoid 12, discharge, shift fork armature 13 is held and is driven shift fork 6 actions, make counting gear 1, rotate a tooth position along clockwise direction, drive minute hand simultaneously and rotate a numerical digit, drive position-limited wheel and the moving tooth plate rotates 36 °.Because position-limited wheel 4, be positioned at below the lower surface of short tooth 16, and wheel rim is stuck in again between the two long teeth, promptly this moment neutral gear 2, be stuck (but position-limited wheel is free to rotate), and, carry gear 5 be fixed on (because of two gears mesh) on the corresponding position by neutral gear 2, in any case this moment, the carry gear 5, will never produce misoperation because of the friction force between its axle sleeve.Have only when counting gear 1, when turning to the 10th time, the outer rim of the pusher dog 14 on the moving tooth plate 3 contacts and stirs short tooth with short tooth 16 and rotates a tooth position, continue after be located at moving tooth plate 3, and the teeth groove 15 on the position-limited wheel 4, make it rotate a tooth position again with back one long tooth engagement simultaneously again; The rotation of neutral gear just drives carry gear 5, rotates two tooth positions synchronously, because of carry gear 5 and counting gear 1.The ratio of the number of teeth is 2: 1, so carry gear 5 drives the short pointer 7 of its sleeve end, has only advanced a numerical digit.At teeth groove 15 and neutral gear 2, break away from engagement after, position-limited wheel 4, outer rim be stuck in again between the two long teeth, neutral gear is blocked, only at counting gear 1, when turning to following one-period again, could repeat above-mentioned action, drive the carry gear and advance a numerical digit, go round and begin again to realize its purpose.
