Problems solved by technology

[0002] In the field of agricultural machinery and agricultural product processing, due to agronomic requirements or the needs of agricultural product processing technology, the speed of its working parts often needs to be adjustable, and the speed adjustment range of the working parts also determines the adaptability of the machine; in the fields of automobiles and tractors, in order to improve The passing performance of the vehicle also requires the gearbox to have more speeds to choose from. For the speed adjustment of the working parts of field machinery, the speed is often adjusted by replacing the gear or sprocket, such as the adjustment of the speed of the seeding shaft of the seeder. The random tool must carry multiple sets of gears or sprockets, which makes the work inconvenient, increases the auxiliary time, and reduces the work efficiency

For the field of agricultural product processing, it is possible to design a multi-gear gearbox, but the cost is high, which affects the economy of use; there is also a variable frequency motor for speed regulation. Although the speed adjustment is convenient, it is generally only suitable for light-load occasions, otherwise it will Reduce the life of the frequency converter; automatic transmissions in the fields of automobiles and tractors, the automatic transmission technology based on hydraulic torque converters has matured, but it has problems such as low efficiency, power loss, and high cost. In terms of mechanical efficiency, its power loss is higher than that of mechanical gearboxes
