Novel transmission device for middle-size and small-size vertical type axial-flow pumps

The utility model provides a novel transmission device for middle-size and small-size vertical type axial-flow pumps, which is composed of a motor cabinet, a bearing housing component and a transmission shaft. The utility model is characterized in that a sink-type bearing housing component is adopted and are placed below the motor cabinet, thereby lowering the positions of the transmission shaft and an elastic coupling and ensuring that the motor coupling is provided in the motor cabinet and can be connected with a shaft head of a YL type vertical motor. The transmission device for middle-size and small-size vertical type axial-flow pumps has the following characteristics: no requirement for adding a transition member, lowered motor center, improved operation stability of motor, simple structure, good use effect, etc.
