In electrical power transmission, belts are versatile loops of substance that can hyperlink two rotating shafts mechanically and transmit electricity between them. Belts are also the main component in belt drives, in which one particular or a lot more steady belts are fitted above two pulleys at two shafts and rotary movement is transferred from the driving pulley to the pushed pulley.

As compared to chain drives and equipment drives, belt drives operate quietly and smoothly and do not need lubrication. Routine maintenance is also comparatively convenient, and the pushed shaft speed can be easily altered by modifying pulley sizes.

The most frequent sorts of belts are V-belts and timing belts. V-belts are the most typical variety of belt nowadays, and as their title implies, their cross-sectional shape arrives in the form of a “V”. CZPTly limitless, the “V” cross-sections of these belts lodge in the mating grooves of their corresponding V-belt pulleys, avoiding slipping because of to beneath-tensioning. In standard, V-belts need significantly less width and rigidity in comparison to flat belts.

Timing belts are toothed belts that empower constructive travel. They have rows of interlocking enamel that suit securely with a toothed pulley to stay away from slipping. Timing belts require much less stress than other belts, have no slippage, and do not require lubrication, nonetheless their energy ability is reduced than V-belts and chains. They are frequently utilised in camshafts of automobiles and crankshafts.
