屏蔽泵电动机转子联接环结构
摘要：
本发明涉及一种屏蔽泵电动机转子联接环结构。本发明对转子联接环环的设计和转子联接环凹槽设计结构进行了详细的说明，解决了转子联接环与转子铜条间的焊接质量控制问题，保证了电机转子鼠笼式绕组导电的可靠性和60年使用寿命的功能性，通过优化方案的转子联接环凹槽的选择，设计具有更好的焊接特性以及较低的应力幅值和疲劳使用率，最终确定转子联接环凹槽内部坡口角度的设计和梯形结构设计，实现其转子鼠笼式绕组导电性的功能。并通过转子联接环和转子铜条的焊接质量保证其60年免维护设计的实现。
摘要（英）：

The invention relates to a shielding pump motor rotor connecting ring structure. The design of a rotor connecting ring and the design structure of a rotor connecting ring groove are explained in a detailed way so that the problem of welding quality control between the rotor connecting ring and the rotor copper bar can be solved, and the reliability of motor rotor squirrel-cage winding conduction and the functionality of the service life of 60 years can be guaranteed. The design has better welding characteristics and lower stress amplitude and fatigue rate through selection of the rotor connecting ring groove of the optimization scheme, and finally the design of the internal bevel angle and the design of the trapezoidal structure are determined so that the function of the rotor squirrel-cage winding conductivity can be realized. Besides, the 60-year maintenance-free design can be guaranteed by the welding quality of the rotor connecting ring and the rotor copper bar.
