Designers snowmobiles know that linking directly to the crankshaft of the engine and the propeller is unprofitable: too high engine speed do not allow to use aredigital optimally. To reduce the propeller revolutions Amateur designers use chain gear, ploskostopie belts, banded V-belt transmission. You can meet the most reliable and compact single-stage gear reducers. As a rule, however, they are quite complicated. The most simple design managed to develop one of the enthusiastic Amateur “aerosanitary” from the city of Tchaikovsky, Perm region M. Psarev. On the processability of the mechanism at least tells TC that he “produced” a kind of microseries — was repeated at least five times. Today we introduce you to drawings and manufacturing technology of the gear.
GEAR FOR SNOWMOBILE
Almost all designs drive bikes have a common drawback that reduces their efficiency. This defect is uneconomical expenditure of muscular energy in the change efforts from one foot to the other during the passage of the pedals ‘dead spots’ (the vertical position of the connecting rod). A large part of the muscular effort at this point is directed to the axis of rotation of the pedals and not so much does the useful work, how much increases the wear of the bearings of the carriage. No wonder the cyclists before the withdrawal of the rods from the vertical position. As a result the course begins with partial loss of muscular energy, which causes premature fatigue of the cyclist.
If you live not too far from the pond, make our drawings Dinghy, and you will experience all the delights of sailing. But if this ancient engine is not too attract you, the body of the Dinghy can be used as the basis for small motor boats or rowing Dinghy. Materials for it will require only two sheets of plywood and pine slats.
Here come the summer. Where are you going to spend it? If near water, we propose to construct the original floating tool – equiped, that is a Pedalo. He will give you the opportunity to sit in on the morning dawn with a fishing rod, ride on the pond, to explore its most hidden corners.
Diverse and numerous family water bikes, but they all have a major flaw: transport them by land very difficult. Another thing — ampipe, on land he feels as confident as on the water. The secret to this versatility in the propeller — crankshaft with propeller wheels when traveling on the roads is the leading “front axle”.

Light truck, which I did for a holiday farm called “Edelweiss”, is difficult to attribute definitely to any type of vehicles. He rigidly jointed (of two parts) frame. On the front of the assembled engine from scooter “Tourist”, and in the back — a homemade body.
Autocostruzione — a long-standing passion of Krasnoyarsk Vladimir Alexandrovich Hassan. The readers interested in self-made machines, will probably remember and “Mini-Valga”, and “Buggy-350″… And here’s another one, just finished work. But unlike the previous one, where A. Hassan was the developer and Builder of the car, here he plays the role of the musician — the entire design and engineering linkages took on the son of Vladimir Alexandrovich, engineer-motorist Vladimir Hassan. And so, family debut.
Me years members Vorovskogo mug Seversk high school № 44 of Krasnodar territory are engaged in constructing a small-sized agricultural machines. The guys understand the importance of this kind of creative search, because has experienced the difficulties associated with manual tillage. Collective and state farms simply: to handle their huge fields of a set of mechanisms. For small parcels such cars practically does not exist a shovel, a hoe, a rake here, perhaps, and all the mechanization on the school or piticescu plot.
Since childhood read “modelist-Konstruktor” — he learned a lot of interesting technical ideas and developments. According to publications in the journal while still in school, redid the bike in the sled on the tires, and then with a crawler gear. During the construction of the manor house has designed a variety of tools and mechanisms to facilitate construction. And now with great pleasure engaged in technical creativity. Today, mainly from units and units decommissioned or abandoned equipment, collected four tractors, which offers its readers.
