Abstract
Provided is an isolated transmission device. The isolated transmission device comprises a transmission shaft which is divided into a driving shaft and a driven shaft, wherein a heat insulation connector is installed in a driving end of the driven shaft, the heat insulation connector is used for connecting the driving shaft of a power device and isolating heat transmission between the driving shaft and the driven shaft, and a load end of the driven shaft outputs power. The driven shaft is connected with the driving shaft via the heat isolation connector, wherein the driving shaft is a rotary shaft of a motor, the load end of the driven shaft is placed in the environment where power driving is required, and the motor is in an external environment. The heat isolation connector is employed to isolate the driving shaft of the motor from the load end of the driven shaft, thereby blocking out heat transmission along a power shaft of the motor. It is prevented that high temperature of the load end is transmitted into the motor via the driven shaft, which leads to high temperature or overheating inside the motor, influences the service life of the motor, or even burns the motor out; or it is prevented that coldness is transmitted into the motor that has stopped running, which leads to solidification of lubricating oil inside the motor, thereby effectively protecting the motor against burning out when the motor is started.
