Abstract
A differential gear type number-of-turns counter belongs to the technical field of instrument manufacturing and comprises a support, a transmission shaft, a master gear, a slave gear, a master magnet, a slave wheel shaft, a circuit fixing plate, a master magnet angle sensor, a slave magnet angle sensor and a single chip microcomputer. When the magnetic field magnetizing device works, the transmission shaft is driven to rotate, the main gear drives the auxiliary gear to rotate, the main gear drives the main magnet to radially magnetize, the magnetic field position is sensed by the main magnet angle sensor, meanwhile, the auxiliary gear drives the auxiliary magnet to radially magnetize, the magnetic field position is sensed by the auxiliary magnet angle sensor, and the main angle sensor and data obtained from the auxiliary angle sensor are calculated through the single chip microcomputer to obtain the rotating circle number position. The utility model discloses reduce the degree of difficulty such as machinery, circuit, technology, raise the efficiency and stability.
Description
Technical Field
The utility model belongs to the technical field of the instrument is made, a counter is related to.
Background
The traditional multi-turn counter of the existing like product is realized by a plurality of gear sets (usually 3-5 gear combinations) under the condition of less turns (within 64 turns), and 64 turns are realized by 5 gears. And the manufacturing process is high in difficulty, the cost is high, and the realization difficulty is high. The stability is poor due to the large number of parts.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a differential tooth formula number of turns counter.
The utility model mainly comprises a bracket, a transmission shaft, a master gear, a slave gear, a master magnet, a slave wheel shaft, a circuit fixing plate, a master magnet angle sensor, a slave magnet angle sensor and a single chip microcomputer, the master gear meshes with the slave gear, the shaft of the master gear is connected with the transmission shaft, the transmission shaft passes through the bracket downwards, the slave wheel shaft of the slave gear is installed on the bracket, there is a master magnet at the top of the master gear, there is a slave magnet at the top of the gear, the circuit fixing plate is installed on the bracket, above the master gear and the slave gear, the master magnet angle sensor and the slave magnet angle sensor are installed on the bottom surface of the circuit fixing plate, the master magnet angle sensor corresponds to the position of the master magnet, the slave magnet angle sensor corresponds to the position of the slave magnet, the single chip microcomputer is installed on the circuit fixing plate, the single chip microcomputer is respectively connected, the number of primary gear teeth is one less than the number of secondary gear teeth.
When the magnetic field magnetizing device works, the transmission shaft is driven to rotate, the main gear drives the auxiliary gear to rotate, the main gear drives the main magnet to radially magnetize, the magnetic field position is sensed by the main magnet angle sensor, meanwhile, the auxiliary gear drives the auxiliary magnet to radially magnetize, the magnetic field position is sensed by the auxiliary magnet angle sensor, and the main angle sensor and data obtained from the auxiliary angle sensor are calculated through the single chip microcomputer to obtain the rotating circle number position.
Taking the example that the master gear is 31 teeth and the slave gear is 32 teeth, the data difference between the master gear and the slave gear is fixed and non-repeated within 32 circles for each rotation of the master gear, as shown in the following chart:
the resolution of the magnetic angle sensor is 0-1023
The singlechip is connected with a cable through a circuit fixing plate and can be connected with devices such as a display, a memory and the like through the cable.
The utility model discloses can solve the problem of few number of turns bull gear with two gears, reduce difficulty such as machinery, circuit, technology, reduce the product volume to solved a lot of problems because of the unable installation of space reason, raise the efficiency and stability.
