Ištrauka

Worm-gear drives have wide application in mechanics because they have noisless operation, they can have rather high transmission ratios and not very big dimensions. Their work is even and uniform. Among shortcomings we have to note not big efficiency, they produce big amount of heat, they are rather expensive, because their production should be very accurate. Designed worm-gear will be used in the factory for moving crane base. Moving crane is carrying a load, so the movement of crane should be uniform, even. As worm-gear work is noisless, it increases comfortability for workers. Working medium is not "active". ...
