Pump shaft structure

Abstract

The invention relates to a pump shaft structure. The pump shaft structure comprises a pump shaft and a motor shaft arranged in the pump shaft in a sleeve mode, a key groove is formed in the motor shaft, a key is arranged in the key groove, and a fixing device sequentially penetrates through the pump shaft, the key and the motor shaft to fix the pump shaft and the motor shaft together. the motor shaft, screws, the pump shaft and the key provided in the pump shaft structure are all standard parts except the pump shaft, the motor shaft, the screws and the key are standard parts, and the pump shaft is made of stainless steel, the motor shaft is embedded in a pump shaft end hole, the motor shaft and the pump shaft are fixed through the key in the key groove in the shaft, and the pump shaft, the motor shaft and the key are fastened together through the screws. According to the pump shaft structure, compared with a traditional shaft structure, the shaft structure is safer and more reliable, convenient to machine and disassemble, stable in operation and high in universality, the total length of the shaft can be effectively shortened through the structure, operation is stabler and lasting, cost is reduced, and meanwhile the service life of the whole pump and quick-wear parts of the pump is prolonged.

Description

technical field [0001] The invention relates to a pump shaft, in particular to a pump shaft structure that is safe, reliable, easy to process, easy to disassemble, stable to run, and highly versatile, and the structure can effectively shorten the total length of the shaft. Background technique [0002] The pump shaft is a device used by the motor to transmit power to the pump. The traditional structure is to connect the pump shaft and the motor shaft by a coupling. The traditional structure is bulky, inconvenient to disassemble, replace and repair; the concentricity of the connection points of the traditional structure is poor, resulting in high vibration and noise during pump operation, which seriously affects the service life of the pump; the shaft length of the traditional structure is too long, and the transmission torque is not good when the pump is running Stability, aggravating the vibration of the pump, seriously affecting the life of the unit, improving the structur...
