Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
The present invention is a instrument showing the action line of gear that can be vivid, main as experimental apparatus and instruments used for education.The appearance of this product is mainly that numerous teachers and students serve, and the reason of profundity is talked about thoroughly, makes people can understand the problem usually not too noting thinking very soon, thus grasp knowledge very soon.
See 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 the first enameled wire that is some and face line parallel, every root first enameled wire correspondence is connected for the LED 5 showing action line with one, and LED 5 is arranged on the gear teeth one end of the gear 1 that insulate along the flank profil track of insulation gear; Each LED 5 is fitted in one end of the gear teeth by plastic plate, and LED just represents the meshing point of action line in this two Meshing Process of Spur Gear.Due to LED 5 along the flank profil arranged in tracks of insulation gear in gear teeth one end of insulation gear 1, LED just can accurately be arranged in the flank profil of gear by such LED, thus accurately shows meshing point, finally reaches the object accurately showing action line.The gear teeth flank of tooth of conductor gear 2 is fitted with one deck conducting resinl, the gear teeth flank of tooth of conductor gear 2 offers groove along the track of conductor gear 2, be inlaid with second enameled wire in groove, the first enameled wire is connected with the positive pole of LED power supply, and the negative pole of LED power supply is connected with conductor gear 2.
See 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, bracing frame is provided with the brace groove for installing insulating gear 1 and conductor gear 2.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 of support 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.Overall shelf is designed to detachable type, and time no, will be placed inside chest, assembling very soon when needs just can be shaping.Such design has fully taken into account the demand of user.
The propulsion system that the present invention adopts adopt stepper motor, and stepper motor is opened loop control unit stepper motor part electric impulse signal being changed into angular displacement or displacement of the lines.When non-overload, the rotating speed of motor, frequency and the umber of pulse of pulse signal are only depended in the position stopped, and not by the impact of load change, when step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by direction initialization, is called " step angle ", and its rotation is that a fixing angle is run step by step.Pilot angle displacement can be carried out by the number of gating pulse, thus reach the object of accurately location; Speed and the acceleration of electric machine rotation can be controlled simultaneously by gating pulse frequency, thus reach the object of speed governing.
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, the effect of vibration damping and raising axle system 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 by the axle of shaft coupling by the axle of stepper motor and fixed conductor gear 2, thus rotates engagement by the rotated versions of stepper motor and energy transferring to gear shaft carrying out driven gear.
The course of work of the present invention: before using 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 in the groove of support 4 respectively, the fixed pair of engaged gears adopting m=16mm, z=20 than transmission demonstrator of gear of the present invention, wherein, insulation gear 1 is as the negative pole of circuit, and conductor gear 2 is as the positive pole of electrode.When stepper motor drives insulation gear 1 to rotate, insulation gear 1 and conductor gear 2 engage, meshing point is passed through to paste the LED for showing action line in one end of the flank of tooth of insulation gear along flank profil track, when power supply is energized, because gears meshing philosophy, the LED composition straight line lighted 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 being stuck.
When finding in R&D process of the present invention to be inlaid with three second enameled wires in groove on the gear teeth flank of tooth of conductor gear 2, along with pinion rotation, insulation gear 1 and each pair of gear teeth of conductor gear 2 contact circuit conducting and the disconnection successively of different contact point successively, LED is luminous one by one, although the straight line of the LED composition lighted successively represents action line.But because manufacturing tolerance causes each enameled wire insulated in gear 1 and conductor gear 2 to there is vertical error, thus can see on end face simultaneously and lead three bright lamps, correctly cannot watch action line.Find through research, when 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 is bright, thus real action line can be observed.
