行星齿轮式动力换e traditional forms of structure, thus causing the transmission accuracy control is not good, the maintenance cost is high; at the same time, there are some security risks. Therefore, the security requirements of the higher, the operation will give the staff to bring a strong shock, so that the operation is very uncomfortable. Although the transmission through the transmission efficiency is high, the transmission effect is good, but the price is more expensive, for the average user to accept. So the research of a new type planetary power
Transmission as a core component in a motor vehicle, when it is working, the engine through the V belt drives the gear box to rotate, thereby indirectly driven by the rotation of the wheels, so that the vehicle.
This paper introduces the theoretical calculation, structure design must be the planetary power shift gearbox working principle and main parts of the strength check and correlation, and the innovative design of the structure, the advantages of the gearbox is a short drive chain, high efficiency, easy to manufacture, use and maintenance are very convenient, more suitable for work in the bad environment, the most important is its high transmission efficiency
Key words: planetary gear type power shift gear box;Crankshaft;Processing craft;Fixture;
