Abstract
The utility model discloses a turnover gyroscope which is composed of a big spherical crown, a small spherical crown, a post body and the like. The turnover gyroscope is characterized in that: a hollow sphere (such as a table tennis ball) is cut into the big spherical crown and the small spherical crown at the position of 2/3 to 4/5 of the diameter of the hollow sphere; the post body with a polished convex length at the two ends a little greater than the curvature diameter of the big spherical crown is fixed along the symmetric axis of the big spherical crown, and one end of the post body is fixed with the bottom of the inner side of the big spherical crown; the space in the big spherical crown is partially or completely filled with padding; the padding is fixed with the big spherical crown by using glue, and the edge of the inner side of the big spherical crown is coated with the glue; the top part of the small spherical crown is provided with a through hole; the edge at the top part of the small spherical crown is in the same direction as the top part of the big spherical crown, and the small spherical crown is sleeved on the post body, so that the edge of the small spherical crown is fixed together with the edge of the big spherical crown; and the glue is coated at the post body and the through hole at top part of the small spherical crown for fixing. The turnover gyroscope, disclosed by the utility model, is characterized by realizing rapid making of the turnover gyroscope and has the advantages of being extremely simple to make, having obvious effects and adding more educational functions after popularization in teaching.
Description
Technical field
The utility model patent relates to the lecture experiment instrument of demonstration friction square to rotary body upset Changing Pattern, belongs to the physical experiment apparatus field.
Background technology
Upset gyro lecture experiment instrument up till now, we see is to make processing by oneself with wooden mostly, and many technical difficulty are arranged, and is difficult for successfully.Though moulding upset (body) gyro was arranged on the market in recent years to be sold; But for teaching, need the students'creative spirit and the ability of practice; More need provide the practical plan of a quick Fabrication upset gyro; The inventor herein periodical " Physical Experiment " 2002.3 " can fall gyro mechanism research with make " in provide the scheme of the general angle of upset; But how the manufacture craft relative complex accomplishes to be convenient to student's self-control or improvement, simple, rollover effect good and failure rate is low upset gyro, and this patent will address this problem.
Summary of the invention
The utility model patent is to solve the upset gyro of using under classroom or the class, solves the turnover technology of upset gyro emphatically through the built-in material of hollow ball.
The utility model patented technology scheme: a kind of upset gyro is made up of large ball prefix, little spherical crown and cylinder etc.It is characterized in that a hollow ball (like, soldier's pang ball etc.) is cut into large ball prefix and little spherical crown at 2/3 to 4/5 place of diameter; The protruding length of one two ends light is slightly larger than the cylinder of large ball prefix curvature diameter; Fix (fixing) along the axis of symmetry of large ball prefix and with cylinder one end and large ball prefix inside bottom with fast glue; With space segment in the large ball prefix or all put completely soft filling material; With liquid glue filling material and large ball prefix are fixed, blended rubber is smeared the large ball prefix inside edge; Through hole is beaten at the top of little spherical crown, bead is preced with edge, top and large ball prefix top in the same way and little spherical crown is enclosed within on the cylinder, the edge of little spherical crown and large ball prefix edge just in time are fixed together, the through hole that spreads upon cylinder and bead Guan Ding with glue is again fixed.
During experiment, the gyro that will overturn places on the surface level, because barycenter is in the large ball prefix part; The large ball prefix contact plane; Twist cylinder with hand and rotate, just can see that gyro begins to stand upside down in rotation, along with large ball prefix is holded up around vertical axes; The cylinder contact plane begins stable rotation, has realized the upset of gyro.
Its unique distinction of the utility model patent is to have realized quick Fabrication upset gyro.Make extremely simple and easyly, effect is obvious, and promotion conference increases more educational function in teaching.
