摘要： A transmission mechanism includes a planet carrier, a planet gear, a pin, a sliding bearing, and thrust bearings. The planet gear is rotatably disposed on the planet carrier through the pin. The thrust bearings are disposed between one end of the planet gear and the planet carrier, and between another end of the planet gear and the planet carrier, respectively. A first lubrication gap is formed between each thrust bearing and an end surface the planet gear. The sliding bearing is sleeved on the pin and is disposed between the planet gear and the pin. A second lubrication gap is formed between an inner circumference of the sliding bearing and the pin or between an outer circumference of the sliding bearing and the planet gear. Oil channels are disposed on the pin. Lubricating oil enters the first lubrication gap and the second lubrication gap through the oil channels respectively.
