Description

Technical Field

[0001] The utility model relates to the technical field of rotor end rings, in particular to a submersible asynchronous motor with a rotor end ring structure. Background Art

[0002] In the prior art, the key component in the submersible motor, the submersible motor rotor short-circuit ring, also known as the rotor end ring, fixes the bars together by riveting pressure, and at the same time forms an induction coil with a squirrel-cage structure. Currently, the bars used are round bars, and the short-circuit rings on both sides connected to the bars are round-hole shapes, which are easy to process and rivet.

[0003] For example, the patent application with the application number CN201821813483.7 includes a rotor, which is composed of a short-circuit ring and bars. The short-circuit ring and the bars form a squirrel-cage structure. The characteristics are as follows: there are several connecting holes with a trapezoidal cross-section along the axis on the short-circuit ring, the inner side of the connecting hole is shorter than the outer side, the cross-section of the bar is trapezoidal, and the end of the bar is matched and connected in the connecting hole. For this submersible asynchronous motor with a novel rotor short-circuit ring structure, due to the use of special-shaped bars, the output is increased by 1.5 times compared with round bars, and the relative length is reduced by 1.5 times. Therefore, the over-current capacity is enhanced, the output state is increased, and the purpose of high-efficiency capacity increase is achieved.

[0004] However, when the common bars are assembled in the short-circuit ring, if the bars and the short-circuit ring are in an interference fit, it is not convenient for the staff to assemble the bars in the short-circuit ring, thus reducing the assembly efficiency of the rotor end ring. If the bars and the short-circuit ring are not in an interference fit, there is a gap between the bars and the short-circuit ring, thus reducing the assembly effect of the rotor end ring. It is urgent to design a submersible asynchronous motor with a rotor end ring structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a submersible asynchronous motor with a rotor end ring structure to solve the above deficiencies in the prior art.

A first card slot is formed on one side of the first circular ring plate, a second card slot is formed on one side of the second circular ring plate, and an annular gear is fixedly installed on one side of the first circular ring plate.

[0009] The assembly component can facilitate the assembly worker to assemble the conducting bar in the first card slot and the second card slot while performing interference connection on it, thereby increasing the assembly efficiency of the rotor end ring structure and improving the assembly effect of the rotor end ring structure.

[0010] A circular groove is formed on one side of the second circular ring plate. A cylinder is rotatably installed in the circular groove. An assembly gear is fixedly installed on one side of the cylinder. A rhombic groove is formed on one side of the cylinder.

[0011] A circular ratchet is fixedly installed on one side of the annular gear. A ratchet buckle is rotatably installed on one side of the second circular ring plate. A torsion spring is fixedly installed between the second circular ring plate and the ratchet buckle. An arc-shaped groove is formed on one side of the second circular ring plate.

[0012] A rotation groove is formed on one side of the housing. The rotating shaft is rotatably installed in the rotation groove. The rotor core is sleeved on the outer surface of the rotating shaft. A core groove is formed on one side of the rotor core. The conducting bar is arranged in the core groove.

[0013] The limiting component includes a first annular plate, a limiting plate, a spring and a second annular plate. The first annular plate is arranged on one side of the rotor core. A limiting groove is formed on one side of the first annular plate.

[0014] The limiting plate is slidably installed in the limiting groove. The spring is fixedly installed between the limiting plate and the first annular plate. The second annular plate is threadedly installed on one side of the second circular ring plate.
