[0002] The impeller is the core component of the water pump. The motor drives the impeller to rotate, so that the blades of the impeller rotate, so that the water in the pump is sent to a high place under the centrifugal force of the blade rotation, and the rotation of the impeller is driven by the motor through the transmission shaft. In the prior art, the impeller and the drive shaft are driven by a flat key, and then the impeller is fixed on the drive shaft with nuts or bolts, which requires complex processing and many installation steps

Embodiment 1
[0030] A water pump impeller transmission shaft connection structure, including a transmission shaft body 1, an impeller body 2 and a connecting sleeve 3; the material of the connecting sleeve 3 is elastic metal, and the shape of the connecting sleeve 3 is a ring. The outer arc surface of the connecting sleeve 3 is provided with an elastic protrusion 31; the inner ring of the connecting sleeve 3 is sleeved on the transmission shaft, and the impeller body 2 is provided with a shaft hole, and the inner wall of the shaft hole and the protrusion of the connecting sleeve 3 From 31 interference fit. The transmission shaft body 1 has a circular groove 11 , the axial length of the groove 11 is equal to the axial length of the connecting sleeve 3 , and the inner ring of the connecting sleeve 3 is embedded in the groove 11 . The thickness of the connecting sleeve 3 is greater than the depth of the groove 11 . The depth of the groove 11 is 0.5-1 mm. The thickness of the connection slee...

Abstract
The invention relates to the technical field of water pump impeller structures, in particular to a water pump impeller and transmission shaft connecting structure. A transmission shaft body is sleevedwith an annular connecting sleeve. An elastic protrusion is designed on the cambered surface of the connecting sleeve. When the transmission shaft body and a shaft hole of an impeller body are in butt joint and an assembled body is formed, tight interference fit is formed between the assembled body and the inner wall of the shaft hole due to elastic deformation of the protrusion, and positioningconnection of the transmission shaft body and the impeller body is achieved. Compared with a flat key connection manner in a traditional connection manner, the installing steps can be greatly simplified, fixing through additional nuts and bolts is not needed any more, the connecting sleeve is simple in structure, the machining cost is low, impeller body and transmission shaft body connection coaxiality and stability can be guaranteed, and transmission is stable.
