1. the processing of pump shaft is to equipment requirement height, bearing length is influenced by the stroke of equipment after friction welding (FW) welding；
2. pump shaft can deform after friction welding (FW)；
3. need to increase the blank allowance of pump shaft, material cost increases；
4. pump shaft is contacted with pumped (conveying) medium, such as there are pump shaft damage parts, then need integral replacing motor.
5. Package size is big, transportation cost is high.
Based on it is above-mentioned in the prior art the shortcomings that, a kind of novel pump shaft connection structure is needed to make up in existing design
Deficiency provides a kind of processing technology simple, at low cost, convenient transportation Novel pump shaft connection structure.
Utility model content
The utility model solves above-mentioned deficiency of the prior art, provides a kind of Novel pump shaft connection structure, pass through by
The form of pump shaft connection is designed as the form being threadedly coupled to solve the deficiency in existing design, by split type from friction welding (FW)
Structure causes the processing of product, transportation cost to reduce, and split structure is conveniently replaceable part, and pump shaft damage parts need not be replaced
Entire motor, only needs to change the part to break down, and use cost has effectively been saved in convenient and efficient, save trouble and labor.
Technical solution is used by the utility model solves its technical problem：This Novel pump shaft connection structure, the knot
Structure is mainly made of pump shaft ontology, and the pump shaft ontology is split structure, is connected with each other by pump shaft and motor shaft；Institute
The pump shaft and the contact surface of motor shaft stated are equipped with positioning element；The motor shaft is equipped with anti-rotation member.
The positioning element is respectively seam allowance positioning element and end face positioning element.
The seam allowance positioning element is the seam allowance of mutual cooperation being machined with respectively on pump shaft and motor shaft.
The end face positioning element is the end face being bonded to each other being machined with respectively on pump shaft and motor shaft.
The anti-rotation member is machined with screw hole on motor shaft and anti-reverse screw is housed in screw hole.
The pump shaft and motor shaft is respectively equipped with screw thread, the pump shaft and motor shaft and passes through the screw thread mutually company of fastening
It connects.
The pump shaft is corrosion-resistant material, and motor shaft is common metal material.
The beneficial effects of the utility model are：The utility model by the form design that connects pump shaft for be threadedly coupled come
Improve the deficiency in existing design, the advantage is that pump shaft and motor shaft can be processed respectively, the stroke of identical equipment can be completed more
The making of elongated workpieces；Pump shaft and motor shaft are fabricated separately, and deflection is small；Pump shaft and motor shaft are unlike material, can minimum level
Reduce material cost；Pump shaft is contacted with pumped (conveying) medium, pump shaft damage parts is such as occurred, is only needed to change pump shaft；It can individually wrap
Dress, space utilization is more reasonable, and transportation cost is low.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in the figure：A kind of Novel pump shaft connection structure, the structure are made of pump shaft ontology 1, and the pump shaft ontology 1 is
Split structure is connected with each other by pump shaft 2 and motor shaft 3；The contact surface of the pump shaft 2 and motor shaft 3 is equipped with positioning
Component 4；The motor shaft 3 is equipped with anti-rotation member 5.The positioning element 4 is respectively that seam allowance positioning element 6 and end face are determined
Position component 7.The seam allowance positioning element 6 is the seam allowance of mutual cooperation being machined with respectively on pump shaft 2 and motor shaft 3.It is described
End face positioning element 7 be the end face being bonded to each other that is machined with respectively on pump shaft 2 and motor shaft 3.The anti-rotation member 5 exists
Screw hole is machined on motor shaft 3 and in screw hole 8 equipped with anti-reverse screw 9.The pump shaft 2 and motor shaft 3 is set respectively
There is screw thread 10, the pump shaft 2 and motor shaft 3 are mutually fastenedly connected by screw thread 10.The pump shaft 2 is corrosion-resistant material,
