Beschreibung
Zusammenfassung:	The invention provides a transmission pin fitting method and device and a drain bucket. The method includes: freezing a transmission pin; fitting the transmission pin into a transmission disc and/or a hollow shaft. According to the transmission pin fitting method and device and the drain bucket, the transmission pin is cooled first to reduce the diameter of the transmission pin according to the principle of thermal expansion, the transmission pin frozen is then fitted into the transmission disc and/or the hollow shaft, and the transmission pin can expand to fully fill a through hole of the transmission disc and/or the hollow shaft when the temperature of the transmission reaches the room temperature. Therefore, the cost is saved, the time of fitting the transmission pin can be shortened, and labor can be saved.
