"507 Mechanical Movements" you can see from the animation and diagram the mechanisms of various gears and mechanisms move

A lot of machines are overflowing in the world, I think that there is not much conscious of the mechanism, but the site introducing the mechanism of such a machine with illustration and animation is "507 Mechanical Movements". There are 507 different mechanisms introduced on the site.

507 Mechanical Movements

The origin of the site was the book "507 Mechanical Movements" of the same name published by author Henry T. Brown in 1868, illustrations and explanations were published in the "21st edition" published in 1908 It is. Even after more than 100 years since publication, things that are only practical from extremely experimental ones are posted. In some casesHTML5Some animated images are displayed using them, and it has been awesome for those who love machines.

Animation looks something like this. On the site, thumbnails with color are displayed.

507 Mechanical Movements, 24

On the site, various machines are introduced over 50 pages.






Besides this, it has been introduced on so many pages, but since each group has been grouped to some extent, it is structured to make it easier to understand as you go through in order .

◆ Transmission of power using a belt
1: Two pulleys (pulleys) connected by a single belt. Both pulleys rotate in the same direction.


2: The belt crossed in the middle. By crossing, the rotation of the driven pulley is reversed. It is simple, but I feel fresh when taught again.


3: I put a guide pulley in the middle of the illustration of "1" and folded the belt halfway. This makes it possible to set the rotation axis of the pulley freely.


5: In the middle of the belt, put "Tension pulley" (B in the figure below) so that the tension of the belt can be adjusted. If the tension of the belt is weak, power will not be transmitted, but if you apply tension to the belt with "tension pulley", you will be able to transmit power.


And, like this, commentary on all mechanisms will be carried out.

8: Changing the diameter of the pulley enables speed change.


9: If you make the pulley into a cone shape, stepless speed change becomes possible. The "CVT(Continuously Variable Transmission) ".


12: Even if you use a pulley and a rope to lift heavy objects like this ...


22: By increasing the number of pulleys, you can lift heavier things. Basically the same mechanism as that described in the science textbook.


24: Gear using gear


25: "Bevel gear" that transmits power at right angles


30: It is hard to believe that Kore will move, a combination of quadrangular gears. It seems to be used in printing machines and others.


31: "Worm gear" combining screw and gear


34: Structure with gear in gear


38: Structure using a deformed gear. What kind of use is there ... ....


40: A tooth of a gear is machined into a V shape. There is a characteristic that the sound is quiet and can convey a great force. The shape of this tooth is an automobile manufacturerCitroenIt is also famous for becoming a motif of the logo.


47: The mechanism of the clutch of the car etc.


58: Transmission mechanism. It is hard to understand in the figure, but as the belt moves to the left, the speed increases gradually. It is the prototype of the automobile transmission.


89: Crankshaft mechanism. It is used for steam engines and automobile engines.


92: Crank and piston mechanism used for steam locomotives and others.


113: Mechanism of "rack and pinion" used for automobile steering and others. It is a mechanism to change the movement of the rotation to the movement of the straight line.


140: It is a mechanism used for "punching machine" which pushes down the lever and punctures the material.


144: Pantograph structure like 'Magic Hand'. The input to the right side is output several times as it is output on the left side.


227: Prototype of chain used for bicycle and so on.


242: It is a mechanism of a drum brake that is also used for bicycles and the like.


249: Ball socket joint used for joints of gas pipes and others.


289: It is used for spring watch etc. and controls movement of second handEscape machineMechanism. By repeating the engagement and disengagement of the tooth and the stopper, the movement of the second hand is born.


376: Mechanism of using horses as power is also introduced.


377: Humans will also power.


387: Automatically adjustable pier. Even if the angle of the pier changes according to the tide filling, the angle of the tread plate is adjusted horizontally.


421: Prototype of reciprocating engine.


425: This is the prototype of the rotary engine.


437: Conceptual diagram of water pump.


448: Well pump that has become less used now.


488: Underwater propeller widely used as a ship's power.


491: It is a hoist used for ship's Ikari. On the foundation, a ratchet type reverse rotation prevention mechanism using a claw is provided.


494: Mechanism of iron nail used when lifting stones and ice chunks. We can grasp the load firmly by using the weight.


In this way, the mechanism of the machine is introduced in the figure and animation.

In addition, the original book can still be obtained at a bookstore and so on.
