Problems solved by technology
The pump shaft is one of the key parts of the multi-stage pump. If the dimensional accuracy, straightness and coaxiality do not meet the requirements, the impeller in the pump will be difficult to install, and the impeller will vibrate or even get stuck during operation.
[0004] The inventor of the present application found that the spline shaft of the water pump in the prior art, the spline shaft is one piece, and the positioning is done by cutting grooves and matching positioning sleeves during processing, and the positioning error is large. The spline groove of the spline shaft is milled, Processing by extrusion and other methods, the processing efficiency is low, and the strength of the spline shaft is poor

Abstract
The embodiment of the invention discloses a water pump spline shaft and a machining method thereof. The water pump spline shaft comprises a spline shaft section, a spline gasket and a smooth round shaft section; the spline shaft section and the smooth round shaft section are arranged on the two sides of the spline gasket correspondingly; the spline gasket is provided with an inner spline hole matched with the spline shaft section and arranged at the end of the spline shaft section in a sleeving mode, and the end surface of the spline shaft section stretches out of the spline gasket; and the end surface of the smooth round shaft section is fixedly connected with the end surface of the spline shaft section through friction welding. According to the water pump spline shaft and the machining method thereof, during water pump spline shaft machining, the spline shaft section is subjected to stretching and solution treatment and then formed after being straightened; the water pump spline shaft is positioned through the spline gasket, the positioning precision is high, in addition, after the spline shaft section is subjected to stretching and solution treatment through the profile, the spline shaft section is formed through straightening, milling and extrusion machining procedures are omitted, and the strength of the spline shaft is high.
Description
technical field [0001] The embodiments of the present invention relate to the mechanical field, and in particular to a spline shaft of a water pump and a processing method thereof. Background technique [0002] A multi-stage water pump refers to a centrifugal pump in which the water inlet section and the water outlet section of the pump are combined through a tie rod. Its output water pressure is very high, and it relies on the rotation of the impeller to obtain centrifugal force to pump out the material. [0003] Multistage water pumps generally transmit power through the pump shaft (spline shaft). The pump shaft is one of the key parts of the multi-stage pump. If the dimensional accuracy, straightness and coaxiality do not meet the requirements, the impeller in the pump will be difficult to install, and the impeller will vibrate or even get stuck during operation. [0004] The inventor of the present application found that the spline shaft of the water pump in the prior a...
