Beschreibung
Zusammenfassung:	The invention discloses a sealed transmission device which comprises a driving mechanism, a coupler, a transmission shaft, a transmission gear and a seal mechanism; the seal mechanism is arranged on the side wall of a sealed cavity in a sealed way; a connecting hole and a compressed air inlet are arranged on the seal mechanism; the transmission shaft penetrates through the connecting hole in a sealed way; one end of the transmission shaft is provided with the transmission gear, and the other end of the transmission shaft is connected with one end of the coupler; the other end of the coupler is connected with the output shaft of the driving mechanism; the driving mechanism drives the transmission shaft to rotate through the coupler; the transmission shaft drives the transmission gear to rotate so as to transmit the rotary motion to a liquid environment in a sealed way; compressed air is pressed into the connecting hole through the compressed air inlet, so that a high-pressure environment is maintained in the c
