Abstract
The utility model relates to an automobile spur gear and demonstration device for its engage drive for teaching. The fixed device board of the device is made of a wooded board; a movable bracket is made of small square frame wood, and the movable bracket which is fixed in the back of the fixed device board by a bolt can rotate around a shaft; a circular straight tooth cylinder driving gear and a circular straight tooth cylinder driven gear are made of a device whose two surfaces are organic glass color boards and the middle is clamped with benzene boards and fillers; a driving transmission shaft is connected with the straight tooth cylinder driving gear and a driven pulley through a flat key; the straight tooth cylinder driven gear is fixed on the fixed device board through the transmission shaft; the driven pulley and the driving pulley are respectively fixed on a transmission wheel and a motor; dynamic is transferred by a circular belt in the middle; a direct current motor is fixed on the back side of the fixed device board by the bolt; a dry battery is served as power supply; the device can be driven by electricity or hand. The device solves the problem that the true object of a gear is too small to demonstrate in teaching conveniently; the utility model can be widely used in related teaching.
Description
Technical field:
The utility model relates to a kind of automobile straight spur gear and engaged transmission apparatus for demonstrating thereof of the usefulness of imparting knowledge to students.
Background technology:
Gear is a part common in the mechanical drive, also be the strength member in the automobile mechanical, in teaching, how structure, parameter and each relationship between parameters of this part are made clear most important because the gear material object is too little, inconvenience is demonstrated in teaching, brings certain difficulty to teaching.
The utility model content:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of automobile straight spur gear and engaged transmission apparatus for demonstrating thereof.This device can not only show parameter, structure and the connection of single straight spur gear accurate, clear, visually and can reflect two gear meshing transmission process.
The technical scheme that the utility model technical solution problem is adopted is: cement chromatic organic glass with benzene plate or other packing material two sides and make m=20-40, two circular straight spur gears of tooth number Z=20-30, the flank of tooth can replace with approximate circular arc, circle line (white) at the bottom of draw on the gear surface reference circle line and tooth, the shapes such as wheel section, keyway of drawing with colored paster, being attached to the last electricity consumption of gear surface is drilled in circle centre position and gets through the hole, on driving gear, be provided with keyway, make the square plank of a band frame again and be provided with travel(l)ing rest, on the plate face, paste with white paster.In position make a call to two apertures, pitch-row be two reference diameters and half, two gears are fixed on the plank with cantilevered axle, wherein initiative drive shaft is free to rotate.On each individual gears, all can image express parameters such as modulus, point circle, dedendum circle, reference circle, ad., height of teeth root, whole depth, transverse tooth thickness, tooth pitch, groove width, rotate two gears, can reproduce the overall process of tooth mesh, reflect the contents of courses such as rotation direction, ratio of gear.
The beneficial effects of the utility model are: it can accurately express the structure of straight spur gear, abstract parameter and connection visually, reproduce the overall process of the engaged transmission between two straight spur gears, simple in structure, be convenient to teaching, improve students'interest in learning and teaching efficiency.
