Mechanical gyroscopes are different. The rotary gyroscope is especially interesting. Its essence lies in the fact that a body rotating around its axis is quite stable in space, although it can change the direction of the axis itself. The rate of rotation of the axis is significantly lower than the rate of rotation of the edges of the gyroscope. Rotating a gyroscope is like moving a whirligig on the floor. The difference between a whirligig and a gyroscope is that the whirligig is free in space, and the gyroscope rotates at strictly fixed points located in the outer bar, and has protection so that it continues to rotate when falling.
It is necessary
- - two lids from cans
- - a piece of laminate
- - electrical tape
- - nuts 6 pcs.
- - steel axle or nail
- - plasticine
- - glue
- - 2 bolts
- - thick wire
- - drill, file
Instructions
Step 1
With these parts in hand, we can start assembling the rotor. Exactly in the center of the lids from the cans we punch holes, preferably with the same nail as the one from which we will make the rotor axis. Then, using plasticine, we fasten the nuts on the lid, you can put more than six, the weight along the edge of the rotor will increase its rotation time.
Step 2
Next, we make an axis. To do this, we fix the electric drill in a vice, tighten the nail without a cap in it and sharpen it with a file. This will keep the axle sharpening as close to the center of the axle as possible. It is necessary to sharpen from both sides.
Step 3
Without removing the sharpened axis from the drill, we will make a groove for the thread, which will start the rotor. We attach a cover with nuts to the axle using glue, but do not use one that hardens too quickly. Poxipol works well. Coat the nuts with the same glue.
Step 4
Now the most important thing is balancing. While the glue dries, you need to position the weights perfectly around the edge of the lid. We turn on the drill (vertically), if the rotating rotor hits in one direction, then some weight is not located correctly. Correcting, trying again. Lubricate the nuts from above and cover with the second lid. We glue electrical tape on the edges of the rotor. Dry. The rotor itself is ready!
Step 5
We take two longer bolts, fasten them in a vice and punch recesses in them, in which the rotor will be fixed. Now you need to come up with an outer frame. Cut a circle out of the laminate. It is better to draw it in advance with a compass. Immediately draw vertical and horizontal lines at a 90 degree angle. Inside, we cut out a smaller circle, but such that the rotor would fit there. Along the horizontal lines we make holes for the bolts against each other. We screw in the bolts. We place the axis of our gyroscope between them. In this case, you must not tighten too tightly, otherwise friction will extinguish the rotation speed, and nothing will work. Leave about 1 mm of travel, but so that the gyroscope does not fall out of the bolts. We glue the bolts to the bar so that vibration does not unscrew them from the frame.
Step 6
It remains only to establish protection. We take a thick wire, bend it into a ring. At the place of the marked horizontal line, we attach it to our product. The gyroscope is ready. We wind the thread on the axle and, pulling sharply on it, we check the performance.
