Basic characteristics of chain transmission
compared with belt transmission, chain transmission has no elastic sliding and slipping, and can maintain an accurate average transmission ratio; The required tension is small, and the pressure acting on the shaft is also small, which can reduce the friction loss of the bearing; Compact structure; It can work under high temperature, greasy dirt and other harsh environmental conditions
compared with gear transmission, chain transmission has lower requirements for manufacturing and installation accuracy; When the center distance is large, the transmission structure is simple. The instantaneous chain speed and instantaneous transmission ratio are not constant, so the transmission stability is poor, and there is certain impact and noise in the work
the average transmission ratio of chain drive is accurate, the transmission efficiency is high, and the distance between shafts is applicable to a large range. It can be used in 205 aluminum alloy window supports in high temperature and humidity environments; However, chain transmission can only be used as parallel shaft transmission, and its instantaneous transmission ratio fluctuates, and the sensor transmission noise is large. Because the chain link cylinder drives the hanging basket to move up and down in the cold and hot groove is rigid, there is polygon effect (i.e. uneven movement). This movement characteristic changes the instantaneous transmission ratio of the chain transmission and causes additional dynamic load and vibration, which must be considered when selecting the chain transmission parameters. Chain drive is widely used in transportation, agriculture, light industry, mining, petrochemical industry, tightening the preferential policies for machine tools and traditional fuel vehicles, and relaxing the policies for new energy vehicles
