Abstract
The utility model relates to a double gem step driving type counter, which is a displaying device used for electric meter power measurement. The utility model can be used as a display unit for counting in other industries. The structure of the utility model is provided with a frame, and a counting character wheel is installed in the frame. A step motor and a driving speed reducing gear are installed on one end of the frame. The utility model is characterized in that a gem bearing is installed on both end of a rotor drive shaft of the step motor, and the gem bearing is fixed on a base frame of a motor. A metal gear is adopted by the driving speed reducing gear, and a metal frame is adopted by the frame.
Description
What the two jewel stepper drive formula registers of the utility model related to is a kind of display device that is used for the watt-hour meter electric energy metrical, also can be used in the other industry as the counting display unit.
The common in the market stepper drive formula register that is used for watt-hour meter, its stepper motor output shaft adopts the supporting of pedestal hole, exist rub-moment greatly, not wear-resisting problem, and temperature influence easily produces distortion, cause motor not have enough torsion band character wheels, produce the card word, stop walking phenomenon, directly influence the life-span of single-phase watt-hour meter, have obvious weak point.Register character wheel structure is adopted the ABS plastic framework in addition, the gear of speed reduction unit also adopts ABS plastic to make, have plastic shrink and bring the gear matched tolerance to differ, precision is low, the operation noise is big, block word, lose word rate height, and numerous product qualities of selecting for use this register to produce electronic watt-hour Watch Factory are affected.
The purpose of this utility model is to provide a kind of pair of jewel stepper drive formula register at above-mentioned weak point, at stepping motor rotor driving shaft two end devices jewel bearing is arranged, the gearing speed-reducer gear adopts metal gear, framework adopts metal framework, stepper motor pivoting friction coefficient is reduced greatly, the moment of resistance is little during rotation, noise because of rubbing and bringing greatly when solving the gear rotation, card, unrest, dead word phenomenon have also been overcome because of reducing the moment of resistance simultaneously, accurate measurement has improved product quality and serviceable life.
Two jewel stepper drive formula registers take following scheme to realize: two jewel stepper drive formula register structures have framework, meter degree character wheel is housed in the framework, framework one end is equipped with stepper motor, transmission reduction gearing, it is characterized in that at stepping motor rotor driving shaft two ends jewel bearing being housed, jewel bearing is fixed on the motor pedestal.The transmission reduction gearing adopts metal gear.Framework adopts metal framework.
Two jewel stepper drive formula registers are because stepping motor rotor driving shaft two end devices have jewel bearing, and are therefore wear-resisting, moment of friction is little, linear expansion coefficient is little, the moment of resistance is little when rotating, the life-span is long.Because the register framed structure adopts metal framework, overcome owing to card, unrest, dead word phenomenon that frame deformation occurs, improved metering accuracy.The transmission reduction gearing adopts metal gear, and the moment of resistance is little during rotation, and is therefore reliable, noise is little, overcome plastic gear processing comprehensively and shunk the gear matched tolerance of being brought and differ, assemble the bad problem of consistance, improved work efficiency and product quality.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is two jewel stepper drive formula register structural representations.
Fig. 2 is two jewel stepper drive formula register electric machine structure synoptic diagram.
Fig. 3 is two jewel stepper drive formula register electric machine structure cut-open views.
With reference to accompanying drawing, two jewel stepper drive formula register structures have framework 1, framework 1 can adopt metal frameworks such as aluminium alloy, meter degree character wheel 2 is housed in the framework 1, meter degree character wheel 2 is made of several character wheels, transition shift fork 11 is housed between the character wheel, and framework 1 one ends are equipped with stepper motor 7, transmission reduction gearing.The transmission reduction gearing is made of motor-driven gear 5, transmission reduction gearing 4,3,8,9,10, and the transmission reduction gearing can adopt metal gear.Guard shield (radome) 6 is equipped with in stepper motor 7, transmission reduction gearing outside.Stepper motor 7 has motor pedestal 12, and motor pedestal 12 can be made of forward and backward two parts.Left stator 18, right stator 14 are housed on the motor pedestal, and stepper motor coil 19 devices are on the stator piece of the left and right sides.Stepping motor rotor 13 devices are at stepping motor rotor driving shaft 17 two ends, and device has jewel bearing 15,16 respectively, and jewel bearing 15,16 is fixed on the motor pedestal 12.
Two jewel stepper drive formula register principle of work: two jewel stepper drive formula register motors are to adopt a pair of bipolar centering type stepper motor, when not having electric current to pass through in the coil 19, because there are inhomogeneous gap in rotor 13 (permanent magnet steel) and 14,18 of left and right stator pieces, exist a static torque to make rotor static on the equilibrium position between rotor and stator.When passing through a positive pulse in the coil, because the magnetic field that coil 15 produces, produce a pair of magnetic pole at the stator piece two ends, because the inhomogeneous gap between stator and rotor makes stator produce a driving torque to rotor, promoting rotor rotates to another equilibrium position along clockwise direction, promptly rotate 180 °, thereby finish the motion in a week.Because stepper motor drives first character wheel of register (The Scarlet Letter wheel) by the transmission reduction gearing, rotate by first character wheel again and a week turn over a word by second character wheel of transition shift fork 11 drivings, rotate by second character wheel and a week to drive the 3rd character wheel and turn over a word by transition shift fork 11, by that analogy, so measure the electric degree number.
