Summary of the invention
In order to overcome that existing mechanical classroom train demonstration teaching aid weight is large, demonstration combination is single and not shortcoming intuitively of demonstration effect, the utility model provides a kind of mechanical classroom train demonstration teaching aid, and this teaching aid has advantages of that weight is less, can combine according to demand and demonstrating visual.
The utility model solves the technical scheme that its technical matters adopts:
A kind of mechanical classroom train apparatus for demonstrating, it comprises horizonal base plate, floor, pivoted arm, gear, pointer, bearing, vertical base plate, support, outer ring rubber ring, inner ring rubber ring, worm gear, worm screw, large rubber ring, described gear comprises cylindrical gear, bevel gear, horizonal base plate is connected with vertical base plate by floor, horizonal base plate and vertical base plate are respectively equipped with regularly arranged through hole, are used for fixing bearing or support; Described support top is provided with worm screw, cylindrical gear, bevel gear are fixed in vertical base plate by bearing, or worm gear is fixed on horizonal base plate by worm screw and support, between bearing, connect the composition train of intermeshing between cylindrical gear or bevel gear by pivoted arm.
Described bearing outer ring first overlaps outer ring rubber ring, then is embedded in through hole, and bearing inner race also overlaps inner ring rubber ring, then is inserted in axle.
Described outer ring rubber ring and gear junction are provided with a pointer, and pointer is L-type, and pointer one end is inserted in the gap of outer ring rubber ring and gear junction, and fixes by friction force, the other end and gear radial parallel.
Described horizonal base plate or vertical base plate adopt transparent plastic sheet material.
Described gear adopts light material.
The beneficial effects of the utility model are, can allow very intuitively observation of students to train motion process and rotating speed speed, can make teacher have multiple demonstration scheme, whole teaching aid all can and can directly be purchased available material by plastics and form, simple in structure, cost is lower.
