Abstract
A portable gear train demonstration teaching aid, axle I and axle II are fixed on same slide block by bearing seat, and axle III and axle IV are fixed on same slide block by bearing seat, and axle V is fixed on separately on a slide block; Three slide blocks are slidably mounted on respectively on three guide rails; On motor shaft, be fixed with driving pulley, axle I is fixed with driven pulley, and belt is centered around on driving pulley and driven pulley; Driving gear and the engagement of axle II follower gear in axle I; Axle II is connected by shaft coupling with axle III, and axle III is fixed with drive sprocket, and axle IV is fixed with driven sprocket, and chain meshes with drive sprocket and driven sprocket respectively; Axle IV one end is connected with one end of worm screw by shaft coupling, worm and wheel engagement, and axle V is contained on worm gear.This device box is convenient for carrying, and inner gear train can arbitrarily be dismantled, install, the mode of demonstrating easily can be extraordinary the teaching of adaptation teacher on classroom, by this device, can make the relative merits of each mechanism of student's more intuitive understanding.
Description
Technical field
The utility model relates to demonstration teaching aid technical field, is specifically a kind of portable gear train demonstration teaching aid.
Background technology
Existing mechanical transmission mechanism teaching aid is generally independent demonstration teaching aid, and this type of teaching aid is generally to demonstrate separately each gear train, is not easy to student all kinds of mechanical drive are watched and compared, and increased the expense of teaching.Also have the teaching aid that can simultaneously demonstrate a plurality of gear trains, but this kind of teaching aid is all not easy to carry, inner gear train can not be dismantled, and is the demonstration teaching aid of a whole large part, is not easy to teacher and on classroom, carries at any time, demonstrates.
Utility model content
For the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of portable gear train demonstration teaching aid.
The technical solution of the utility model is: a kind of portable gear train demonstration teaching aid, comprise motor, axle I, axle II, axle III, axle IV, axle V, slide block, guide rail, casing, it is characterized in that: in casing, be provided with axle I, axle II, axle III, axle IV, five axles of axle V, axle I and axle II are fixed on same slide block by bearing seat, axle III and axle IV are fixed on same slide block by bearing seat, and axle V is fixed on separately on a slide block; Three slide blocks are slidably mounted on respectively on three guide rails, and three guide rails are fixed on the base plate and a side plate of casing; On motor shaft, be fixed with driving pulley, axle I is fixed with driven pulley, and belt is centered around on driving pulley and driven pulley; In axle I, be also fixed with driving gear, axle II is fixed with follower gear, driving gear and follower gear engagement; Axle II is connected by shaft coupling with axle III, and axle III is fixed with drive sprocket, and axle IV is fixed with driven sprocket, and chain meshes with drive sprocket and driven sprocket respectively; Axle IV one end is also connected with one end of worm screw by shaft coupling, worm and wheel engagement, and axle V is contained on worm gear.
Described each slide block can slide and dismantle from guide rail.
Described casing is connected through the hinge and is formed by six blocks of aluminium sheets, closed with snap close.
Advantage of the present utility model: this device box is convenient for carrying, inner gear train can arbitrarily be dismantled, install, the mode of demonstrating easily also can be extraordinary the teaching of adaptation teacher on classroom, by this device, can make the transmission of student's more intuitive understanding band, chain transmission, gear drive and worm geared feature, principle of work and structure, and its relative merits separately relatively, also can demonstrate separately modules, thereby grasp the ABC of mechanical drive design, rationally draft Mechanical Drive Type.
