The difference between belt drive and gear drive

The biggest difference between belt transmission and gear transmission lies in the transmission mode. Belt drive is driven by friction, and the driving wheel and driven wheel rotate similarly; Gear transmission is driven by the extrusion of gear teeth, and the driving wheel and the driven wheel rotate in opposite directions. Using belt drive for a long distance, the speed ratio is not high or the load impact force is too large, which is easy to cause slipping. In contrast, gear transmission will not cause slippage, and it is suitable for use in occasions with compact structure and large speed ratio. There are also differences in efficiency between the two. Excellent gear transmission rate can reach 98-99%, while belt transmission efficiency is relatively higher, reaching 99%. Design and manufacturing level are important differences between them. In view of the loss of oil, the belt transmission system will not be harmed, and the gear transmission mode needs to maintain the necessary pressure. The pressure value at no-load is mostly above 2.5bar, even as high as 4.0bar, while the no-load pressure of belt drive mode is generally 0. I hope the above introduction can help car owners in daily use.
