Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
The present invention is the instrument of a action line that shows gear that can be vivid, mainly as experimental apparatus and instruments used for education.The appearance of this product mainly, for numerous teachers and students' service, is talked about abstruse reason thoroughly, makes people can understand very soon the problem of usually not too noting thinking, thereby grasps very soon knowledge.
Referring to Fig. 1-2, the present invention includes that be arranged on support 4 can intermeshing insulation gear 1 and conductor gear 2, and conductor gear 2 is connected with propulsion system by shaft coupling, the flank of tooth of insulation gear 1 is provided with some first enameled wires parallel with flank of tooth osculatory, every the first enameled wire correspondence is connected for the LED lamp 5 that shows action line with one, and LED lamp 5 is arranged on gear teeth one end of insulation gear 1 along the flank profil track of insulation gear; Each LED lamp 5 is fitted in one end of the gear teeth by plastic plate, and LED lamp just represents the meshing point of action line in this two Meshing Process of Spur Gear.Due to LED lamp 5 along the flank profil arranged in tracks of insulation gears in gear teeth one end of insulation gear 1, LED lamp just can accurately be arranged on LED lamp in the flank profil of gear like this, thereby accurately shows meshing point, finally reaches the object of accurate demonstration action line.On the gear teeth flank of tooth of conductor gear 2, be fitted with one deck conducting resinl, on the gear teeth flank of tooth of conductor gear 2, offer groove along the track of conductor gear 2, in groove, be inlaid with second enameled wire, the first enameled wire is connected with the positive pole of LED lamp power supply, and the negative pole of LED lamp power supply is connected with conductor gear 2.
Referring to Fig. 3, described support 4 is made up of base and bracing frame, and the side of bracing frame is provided with the base groove for laying base, is provided with the brace groove for installing insulating gear 1 and conductor gear 2 on bracing frame.Insulation gear 1 is arranged in the groove of bracing frame by the first gear shaft 3, and conductor gear 2 is arranged in the groove of bracing frame by the second gear shaft 6.The present invention utilizes insulating material nylon sheet to make the frame that supports two single bearing seats.The feature of support 4 of the present invention is that mounting or dismounting are convenient.Can be subject to the restriction of condition owing to considering that teacher attends class, instruments used for education are not easy to carry.The shelf of entirety is designed to detachable type, no time, will be placed chest the inside, and when needs, assembling just can moulding very soon.Such design has fully taken into account user's demand.
The propulsion system that the present invention adopts adopt stepper motor, and stepper motor is the open loop control unit stepper motor part that electric impulse signal is changed into angular displacement or displacement of the lines.The in the situation that of non-overload, the rotating speed of motor, frequency and the umber of pulse of pulse signal only depended in the position stopping, and be not subject to the impact of load variations, when step actuator receives a pulse signal, it is pressed direction initialization with regard to Driving Stepping Motor and rotates a fixing angle, is called " step angle ", and its rotation is that a fixing angle is moved step by step.Can carry out pilot angle displacement by the number of gating pulse, thereby reach the object of accurate location; Can control by gating pulse frequency speed and the acceleration of electric machine rotation, thereby reach the object of speed governing simultaneously.
Gearing of the present invention is shaft coupling, by shaft coupling transmitting torque.In the power transmission of high-speed overload, some shaft coupling also has buffering, and vibration damping and raising axle are the effect of dynamic property.Shaft coupling is made up of two halves, connects respectively with main drive shaft and driven shaft.General engine is mostly connected by means of shaft coupling and working machine.Type of the present invention is connected the axle of the axle of stepper motor and fixed conductor gear 2 by shaft coupling, thereby the rotation form of stepper motor and energy are delivered to driven gear rotation engagement on gear shaft.
The course of work of the present invention: use before apparatus of the present invention, first take out base from the base groove of bracing frame, be assembled into support 4; Then insulation gear 1 and conductor gear 2 are arranged on respectively in the groove of support 4, gear of the present invention is fixed adopts m=16mm than transmission demonstrator, the pair of engaged gears of z=20, wherein, insulation gear 1 is as the negative pole of circuit, and conductor gear 2 is as the positive pole of electrode.In the time that stepper motor drives insulation gear 1 to rotate, insulation gear 1 and conductor gear 2 engage, meshing point is pasted the LED lamp for showing action line by one end of the flank of tooth at insulation gear along flank profil track, in the time that power supply is switched on, because gear engagement philosophy, the LED lamp composition straight line lighting successively, is action line.In addition, first and second enameled wire of the present invention all adopts very thin enameled wire, so just can ensure the correct engagement of gear, and don't as for being stuck.
In R&D process of the present invention, find in the time being inlaid with three the second enameled wires in the groove on the gear teeth flank of tooth of conductor gear 2, along with gear rotates, each circuit conducting and disconnection successively that the gear teeth is contacted successively to different contact points of insulation gear 1 and conductor gear 2, LED lamp is luminous one by one, although the straight line of the LED lamp lighting successively composition has represented action line.But there is vertical error because manufacturing tolerance causes each enameled wire insulating in gear 1 and conductor gear 2, thereby on end face, can see simultaneously and lead three bright lamps, cannot correctly watch action line.Find through research, in the time changing the second enameled wire of conductor gear 2 into one by three, just can guarantee that a meshing point ensures that leading of a LED lamp is bright, thereby can observe real action line.
