Abstract
The utility model relates to a connecting structure of an electric pump rotor shaft and a rotor screen plate of a shielding motor, which consists of a groove, a shaft and a protective ring, wherein the protective ring is welded on the shaft, and the groove is arranged on the protective ring. The product has simple structure and reasonable design. Through the groove formed at the stainless steel protective ring part of a rotor, the single-surface welding and double-surface forming with the stainless steel shaft can be realized, the stress and the fatigue strength of welding seams can be reduced, the welding can be completed in one step without many times of overlaying welding and many times of heat treatment, the welding process and the heat treatment process can be simplified, the rejection product rate of rotating shaft forge elements can be reduced, and the sealing reliability of the shield electric pump shaft and the protective ring welding seam can be improved.
Description
Technical field: the utility model relates to a kind of shield electric machine electric pump armature spindle and rotor plater board connecting structure.
Background technology: between traditional motor electric pump armature spindle and the retaining ring design unreasonable, fluting not on the retaining ring causes welding the back weld seam and is prone to crackle, welding once hands over the inspection qualification rate low, need repeatedly repair welding, repeatedly heat-treat, could guarantee the weld seam sealing without leakage.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of shield electric machine electric pump armature spindle and rotor plater board connecting structure are provided, it is unreasonable that it has mainly solved between traditional motor electric pump armature spindle and the retaining ring design, cause welding the back weld seam and be prone to crackle, need repeatedly repair welding and repeatedly heat-treat, could guarantee problems such as weld seam sealing without leakage.The purpose of this utility model be achieved in that shield electric machine electric pump armature spindle and rotor plater board connecting structure by: groove, axle, retaining ring constitute.Retaining ring is welded on the axle, has groove on retaining ring, and groove is a Ω shape groove.This product structure is simple, reasonable in design, by slotting at rotor stainless steel retaining ring place, can with the stainless steel shaft single face welding and double face shaping, reduced the stress and the fatigue strength of weld seam, can once finish welding, do not need repeatedly repair welding and repeatedly heat-treat, simplify welding procedure and Technology for Heating Processing, reduced the percent defective of rotating shaft forging, improved the sealing reliability of shielded electric pump axle and retaining ring weld seam.
Description of drawings:
Accompanying drawing is the structural representation of the utility model shield electric machine electric pump armature spindle and rotor plater board connecting structure.
