In electricity transmission, belts are flexible loops of material that can link two rotating shafts mechanically and transmit energy between them. Belts are also the major element in belt drives, exactly where one particular or much more steady belts are fitted more than two pulleys at two shafts and rotary motion is transferred from the driving pulley to the driven pulley.

As when compared to chain drives and equipment drives, belt drives run quietly and smoothly and do not require lubrication. Servicing is also comparatively handy, and the driven shaft pace can be effortlessly altered by shifting pulley measurements.

The most widespread types of belts are V-belts and timing belts. V-belts are the most frequent kind of belt today, and as their name indicates, their cross-sectional shape comes in the form of a “V”. CZPTly endless, the “V” cross-sections of these belts lodge in the mating grooves of their corresponding V-belt pulleys, protecting against slipping due to below-tensioning. In standard, V-belts need considerably less width and pressure compared to flat belts.

Timing belts are toothed belts that allow good travel. They have rows of interlocking tooth that in shape securely with a toothed pulley to avoid slipping. Timing belts call for significantly less tension than other belts, have no slippage, and do not call for lubrication, even so their electrical power capacity is reduce than V-belts and chains. They are frequently employed in camshafts of vehicles and crankshafts.
