It would seem that in this field of mechanics it is difficult to come up with something new: in the friction units of machines and devices have from time immemorial used bearings two main types — ball or roller (rolling) and a stub or vladishev (slip). Not only the device but also of their traditional materials: steel, Babbitt, bronze, textolite, special cast iron.WHAT’S NEW BEARING?

Memories of childhood and adolescence accompany the person in his life: about the native log house with a Russian stove; the sun warmed the dusty paths of the garden, the goats (most of the emphasis in conversation and make on the second syllable) for sawing wood, standing in a corner in the yard near the woodshed…
On the night of November 1, 1924, the workers took the first car entirely manufactured in the factory AMO. One of the mechanics, bent his head low in front of the radiator with the Soviet, and not a foreign brand, spun winding the handle-and AMO-F15 No. 1 came to life. A few laps in the factory yard did then this… not even a car, and naked – without a body and cabin – chassis with inverted box on the frame instead of the seat.
the SPECIAL ASSAULT AIRCRAFT of JAPAN. By early 1945, the Japanese military-political leadership was aware that sooner or later we should expect the allied invasion to the territory of Japan proper. This understanding has penetrated all layers of Japanese society. The bombing of cities and industrial enterprises were conducted daily, and the armed forces of the Empire fought desperately, pressed on all fronts.
“Dear edition! In rooms 11 and 12 your magazine from 1973 published a description of the guitar in Leningrad designers and lovers Guzina O. and D. Med, hex. The tool we liked.
I remember a few years ago in the journal “modelist-Konstruktor” there is the material possibility of measuring electrical capacitance using a PC “Specialist”. Then published the program in machine code that allows with reasonable accuracy to determine the values of capacitors in the range of 0.1—1000 UF, and later version of it written in forth language, for which the wording, of course, a huge thank you!
We are not talking about armored planes-fighter planes or combat helicopters, and about real tanks on the tracks. But with wings. It came up in the early 1930s, American designer Walter Christie’s tanks. He proposed to attach to the tank wings and tail, and his powerful motor to make spin the propeller.
The first and most important work on the rotating propeller to generate lift forces were made in the period between the world wars. Thus, it was found that the spinning rotor can generate lift force, maintaining its rotation from the incoming flow. Any drive to the rotor in this case was not needed. This mode is called “autorotation”. Its use allowed the Spanish designer Juan de La Cierva to invent the autogyro.
Specialists, no doubt, will note the advantages of a new car company Renault — RENAULT MEGANE COUPE. Memorable appearance, underlined “big-eyed” slanted headlights and back symmetrical they grilles air intakes at the front of the hood — that’s not all.
The entire model except for the axles and the engine is made of paper and cardboard. It can make students 3rd-5th grade. The model is like a real machine of the separately mounted parts, so building it is best to deal with just a few people. Before proceeding to the construction of the model, it is necessary to review the plans, collect all materials and tools. It is necessary to increase the drawings in the correct scale and make sure they are correct.
