Description

Technical Field

[0001] The utility model relates to the technical field of water pump shafts, in particular to a water pump shaft with a connecting mechanism. Background Art

[0002] The water pump shaft is the core component of the water pump, used to support and transmit power.

[0003] The water pump shaft is usually composed of a shaft body, a sleeve, an impeller and a flange. When in use, before starting the water pump, you first need to check whether the structural composition of the water pump shaft is intact, especially whether the shaft body, sleeve, impeller and flange are fastened reliably. Then, the water pump shaft is driven to rotate by a motor or other driving device, and then the impeller is driven to start rotating. Flange connection is a common connection method. It connects the water pump shaft and the flange with bolts and nuts to fix the water pump shaft to the impeller or other components.

[0004] However, the existing water pump shaft is connected through a flange structure, usually fixed with bolts and nuts. When the water pump shaft rotates, it generates high temperature, which is transmitted to the flange connection, causing the bolts and nuts on the flange surface to loosen. In addition, when the water pump shaft rotates, it generates torque at the flange connection. If the bolt and nut connection becomes loose and the torque is too large, the axis of the water pump shaft will deflect. Excessive torque may cause the bolts and nuts to loosen or break, thereby affecting the tightness and sealing of the water pump shaft flange connection. To this end, we propose a water pump shaft with a connection mechanism. Utility Model Content
