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.

If the hand is a metal sheet or scrap plywood, enter them between the fork tines – get a good shovel.
31 October 1945 the technical Department of the Us air command (the name of the U.S. air force) requested the leading firms, they create new weapon systems capable of hitting targets at ranges from 40 to 8000 km.
European champion 1979, on models of missiles in the category of S-6-A X. Ignota (Spain). In three rounds it model showed the best result, and the fourth, additional, — 3 min.
The first attempts to improve operational mobility artillery through the installation of various caliber guns on tracked or wheeled chassis has been made at the beginning of XX century. There was a certain bias towards the latter, that was no accident. Crawler tractors, and then the tanks were not only much more difficult technically, but much more expensive. Tactics combat use of armored units in 1920 — 1930-e years have not yet been worked out. The role and place of self-propelled artillery clearly were not visible, and most self-propelled artillery as such did not exist. So developers saw significant advantages crawler front wheel. Moreover, the automotive industry in that period had developed rapidly. New impetus for the creation of self-propelled guns on a wheeled chassis gave the appearance of vehicles. The most successful design of this kind admittedly French SPG chassis truck-terrain vehicle Laffly, armed with 47mm anti-tank gun.
