Description
Technical field
The utility model belongs to educational aid field, is specifically related to a kind of Higher Mathematics Teaching surface of revolution demonstration teaching aid.
Background technology
Surface of revolution is the chapter in Advanced Mathematics, also be planform the most common and very important in daily production, life, but the surface of revolution demonstration teaching aid be not applicable at present, be unfavorable for the profound understanding of student to surface of revolution, make troubles to Higher Mathematics Teaching.
Summary of the invention
The purpose of this utility model is the problem in order to solve the surface of revolution demonstration teaching aid be not applicable at present, and provide a kind of Higher Mathematics Teaching surface of revolution demonstration teaching aid, its technical scheme is as follows:
A kind of Higher Mathematics Teaching surface of revolution demonstration teaching aid, it comprises pedestal, rotating shaft, wheel disc, braking vane and Surface forming device; Pedestal is fixedly connected sequentially by header board, top board, rear plate and base plate and forms, the rear end of rotating shaft is rotationally connected by bearing and front and rear panels, in order to increase stability, base plate thickeies and inner filling is plumbous, the rear end face of rotating shaft is arranged on the inside of rear plate, and pedestal can vertical and horizontal both direction steadily be placed; Rotating shaft is provided with a wheel disc between front and rear panels, wheel disc adopts heavy metal material or non-heavy metal material inside to fill with plumbous structure, the diameter of wheel disc is greater than the diameter more than ten times of rotating shaft, be provided with one block of braking vane in the below of wheel disc, the both sides of braking vane are provided with axostylus axostyle and are rotationally connected with front and rear panels; Surface forming device comprises many expansion links and spheroid, many expansion links are arranged in parallel within the side of rotating shaft, one end of many expansion links is fixedly connected with rotating shaft, the other end of many expansion links is provided with the eye-catching spheroid that scribbles fluorescent paint etc., the diameter of spheroid is greater than the maximum gauge of expansion link, be less than or equal to the axis spacing of adjacent two expansion links, the surface of many expansion links all scribbles black coating, and Surface forming device adopts the lightweight materials such as aluminium alloy.
The beneficial effects of the utility model are: spheroid can be made to be arranged in curve shape by adjusting the length of many expansion links, then rotating disk is rotated, the spheroid being arranged in curve shape is rotated and forms surface of revolution, the volume and weight of rotating disk is larger, so rotation time is longer, and can utilize braking vane that rotating disk is stopped operating fast; The utility model one-piece construction is simple, easy to use, does not need power consumption, economize energy, and pedestal can vertical and horizontal both direction steadily be placed, and is beneficial to the profound understanding of student to surface of revolution, brings convenience to Higher Mathematics Teaching, be applicable to popularity use.
