It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, it is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Gear set formula absolute value encoder, as depicted in figs. 1 and 2, including shell 1 and mounting plate 2, shell 1 and mounting plate 2
Opposite side is opposite to be fixed with connecting rod 3, is connected between connecting rod 3 by spring 4, on shell 1 and mounting plate 2 between connecting rod 3
It is respectively and fixedly provided with deck 5, it is equipped with shock absorbing ring 7 between connecting rod 3 and deck 5, through there is shaft 8 between shell 1 and mounting plate 2, installs
Plate 2 is equipped with the through-hole 9 that cooperate with shaft 8, is equipped with bearing on shell 1 with 8 contact position of shaft, equipped with driving tooth inside shell 1
Wheel 11, driving gear 11 is engaged with the first driven gear 12, the second driven gear 13, and shaft 8 is equipped with and driving gear 11
The tooth socket 10 of cooperation, driving gear 11, the first driven gear 12 are respectively and fixedly provided with magnet steel 14 on second driven gear 13, in shell 1
Wall is fixed with circuit board 15, is equipped with magnetic rotation angle of revolution sensor 16 with respect to place with magnet steel 14 on circuit board 15.
Magnetic rotation angle of revolution sensor 16 is for measuring angle of each gear relative to initial position, magnetic rotation angle sensor
Device 16 and circuit board 15 are electrically connected, and driving gear 11, the first driven gear 12, the second driven gear 13 are appointed during rotation
The number of teeth that one moment turned over is equal, driving gear 11, the first driven gear 12, any two gear in the second driven gear 13
The number of teeth meets irreducible relationship, deck 5 two-by-two and is symmetrical set, and it is driven that magnet steel 14 is fixed on driving gear 11, first
At gear 12,13 center of the second driven gear.
Each gear can measure with the angle of initial position by corresponding magnetic rotation angle of revolution sensor 16, realize according to this
Individual pen absolute encoder, therefore encoder can measure minimum angles as corresponding 16 institute of magnetic rotation angle of revolution sensor of driving gear 11
Minimum angles can be measured, minimum angles can be obtained by the resolution ratio of the corresponding magnetic rotation angle of revolution sensor 16 of driving gear 11.
If the resolution ratio of the corresponding magnetic rotation angle of revolution sensor 16 of driving gear 11 is n, absolute value encoder can be measured
Minimum angles are as follows: driven after driving gear 11 rotates a whole circle since driving gear 11 is different from the number of teeth of driven gear
The position that gear can be meshed originally with driving gear 11 can misplace, and the number of teeth of dislocation is the driven gear and driving gear
11 teeth number difference, the position of gear set will not all repeat with any position before, therefore realize circle number encoder according to this.So absolutely
There is a different set of angle-data to correspond therewith any position in value encoder rotation process.Therefore it may only be necessary to
The angle-data of each gear of end state is measured by circuit board 15, can calculate knot by this one-to-one relationship
The circle number that pencil state driving gear 11 is turned over, encoder can also be measured continuously in the event of a power failure and not lose data.
If driving gear 11 rotates in the same direction, until gears all again rotates back into original state, lead at this time
11 turns of moving gear of circle number is the maximum coding circle number of encoder.And the gear structure multi-turn absolute value encoder arranged side by side
Maximum coding circle number calculating method are as follows: the product of each driven gear number of teeth.
Any moment of gear set during rotation, the number of teeth that each gear turns over are equal；Total number of teeth of gear rotation
Equal to the number of teeth that the corresponding number of teeth of number of full circle of gear rotation adds position corresponding to current location；Driving gear 11 is turn-taked
Number is less than most great circle number.Constraint condition is established according to the three above conclusions, the turning collar of driving gear 11 can be calculated
Number.
The setting of shock absorbing ring 7 can be improved the structural strength between connecting rod 3 and deck 5, so as to guarantee that encoder exists
There is metastable working environment, reduction extraneous vibration as far as possible is influenced caused by encoder in the course of work.
Gear set formula absolute value encoder provided by the utility model realizes that individual pen is compiled using magnetic rotation angle of revolution sensor
Code, and using gear set, position is not repeated during rotation, is realized circle number encoder, is not with the more of no-load voltage ratio gear between gear
Grade relationship transmission, but with simultaneously grade relationship transmission, the load of Multi-stage transmission is multiplication relationship, and simultaneously the load of grade transmission is cumulative
Relationship, therefore effectively reduce the load of driving gear；It is simple using the absolute value encoder structure of gear structure arranged side by side, it is conducive to
High speed rotation has both accurate measurement and the measurement of great circle number, can continuously measure and not lose data in the event of a power failure, and existing
No-load voltage ratio gear structure absolute value encoder compare, it is less in identical coding range lower gear number；The setting energy of shock absorbing ring
The structural strength between connecting rod and deck is enough improved, there is metastable work so as to guarantee encoder during the work time
Make environment, reduction extraneous vibration as far as possible is influenced caused by encoder.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features；And these
Modify or replace, can't make corresponding technical solution essence be detached from various embodiments of the utility model technical solution spirit and
