The plastic bevel gears on a recent washer transmission, for example, measure as much as 15 in. Within a decade, injection molded plastic gear transmissions might properly have energy levels as excessive as 10 HP. Epicyclic gear trains are utilized in numerous engineering functions the place specific motion control, speed adjustment, or torque multiplication is required.
Manufacturers usually use alloy steels like nickel-chromium-molybdenum alloys such as 4340 or 4140 to make transmission shafts. These alloy steels are cost-effective and provide a good balance of energy and toughness required for the appliance. More importantly, metal transmission shafts are appropriate with heat …
