Through the demonstration operations of the demonstrator, pupils can acquire the different structures and characteristics of various driving mechanisms while using hands and brains, so that the perceptual knowledge and the rational knowledge of power transmission can be obtained. The utility model is, therefore, suitable for the pupils to receive the primary education of mechanical principles.
Description
The utility model relates to the Transmission mechanism demonstrator that primary school education is used.
For adapting to the scientific and technological cause needs of fast development, cultivate many-sided knowledge talent, according to primary school nature education outline, the student who enters primary school six grades is just begun to carry out the experimental education of physical construction, with tap intellectual resources, allow the student understand secret how to remove to explore principle and the Nature, existing many in recent years teaching aids come out, but major part all is the static toy of simple building blocks form, a kind of by observation, understanding and analysis in conjunction with the physical construction motion, carrying out the learning aid of mechanical principle ushered-in education, is the problem that current urgent need solves.
The purpose of this utility model just is to provide a kind of extremely simple Transmission mechanism demonstrator, allows the student move back and forth in person, to assemble and to observe, and makes the student obtain the perceptual knowledge and the conceptual knowledge of gear train transmission of power.
By above-mentioned purpose, specific embodiments of the present utility model is:
One base plate is arranged, and base plate is provided with two vertical base plate also at a distance of the axle of certain distance, is respectively installed with initiatively driving member and and driven driving member on the axle.
This learning aid is a connecting rod transmission learning aid, described active driving member is a driving wheel, described driven driving member is a slide plate, driving wheel is movably connected by connecting rod with slide plate and is connected, the toggle of connecting rod is located at the eccentric part of driving wheel, in the slide plate guide groove, another activity is engaged in the guide groove other end of connecting rod by fixing finger close-fitting.
This learning aid is a bent axle transmission learning aid, and described active driving member is mounted in the rotating bent axle on the diaxon, and described driven member is a connecting rod, and an end of connecting rod and bent axle flexibly connect.
This learning aid is the belt gear learning aid, and described active driving member and driven driving member are belt pulleys, are set with belt between two belts.
This learning aid is the gear drive learning aid, and described active driving member and driven biography part are gears, and the centre distance of two gears is equal to the distance of diaxon.
The utility model is by the demonstration to four kinds of different gear trains, dismounting, assembling, make the pupil understand that the purposes of gear train is a torque transmission mechanism, different structural shapes obtains different transmission results, as first, second kind connecting rod transmission and bent axle transmission are to be used in to rotatablely move to be converted into the occasion of plane and straight line motion, and the 3rd, the 4th kind belt gear and gear drive are to be used under the constant occasion that rotatablely moves, thereby obtaining the perceptual knowledge and the conceptual knowledge of mechanical transmission mechanism transmission of power, is the indispensable learning aid of pupil to the mechanical principle ushered-in education.

According to above-mentioned accompanying drawing, below the utility model is described in detail again.
Transmission mechanism demonstrator has a base plate (1) and two vertical base plate also at a distance of the axle (7) of certain distance, is respectively installed with initiatively driving member and driven driving member on the axle, and different driving and driven driving members constitute the different kinds of drive.
Scheme 1 is a connecting rod transmission learning aid (referring to Fig. 1), initiatively driving member is driving wheel (2), driven driving member is slide plate (8), driving wheel and slide plate are movably connected by connecting rod (4), the toggle (3) that connects connecting rod is located at the eccentric part of driving wheel, finger (5) close-fitting that is fixed on the connecting rod other end is in slide plate guide groove (6), and another axle (7) is also movable to be engaged in the guide effect that plays skateboarding in the guide groove of slide plate.It serves as that guiding moves with guide groove, axle that the rotation of driving wheel makes slide plate through the promotion of connecting rod, finger, and forming rotatablely moves is converted into the plane and straight line motion.
Scheme 2 is a bent axle transmission learning aid (referring to Fig. 2), initiatively driving member is for being installed in the rotating bent axle (9) on the diaxon (7), driven driving member is connecting rod (9), one end of connecting rod and bent axle flexibly connect, this scheme can be moved by drivening rod by the revolution of bent axle, also be a kind of straight-line exemplary that is converted into by rotatablely moving, generally be used for the crankshaft connecting rod system in the cylinder.
Scheme 3 is belt gear learning aid (referring to Fig. 3), initiatively driving member and driven driving member are belt pulley (11), be set with belt (12) between two belt pulleys, the principle of this learning aid is to utilize the friction force of belt and belt pulley to come transferring power, the character that rotatablely moves is constant, when two diameter pulleys are identical, belong to the constant speed transmission; When big belt pulley, belongs to and drives up during as driven driving member as active driving member, small belt pulley; Otherwise belong to gearing-down.Two belt pulley wheelspans are greater than both radius sums.
Scheme 4 is gear drive learning aid (referring to Fig. 4), initiatively driving member and driven driving member are intermeshed gear (13), the principle of this transmission learning aid is to utilize the transferring power of intermeshing of two gears, and rotation character is constant, a kind of kind of drive of using the most generally in mechanical drive.When two gear diameters are identical, belong to the constant speed transmission; When gear wheel is the active driving member, when pinion wheel is driven driving member, belongs to and drive up; Otherwise belong to gearing-down.Two gear centres of this transmission learning aid are apart from equaling both radius sums.
