Background
The permanent magnet motor is widely applied to various industries, such as the fields of fans, water pumps, air compressors and the like in the industrial field due to high energy efficiency and high speed regulation performance.
In order to ensure the clamping rebound deformation of the split lower end cover and the iron ring rotor structure in the prior art in the turning process of the iron ring rotor, a certain thickness or thickening of the iron ring is generally required to be ensured, so that the weight of a product is overweight and the cost is overhigh, the split connection has high requirements on the process of motor assembly tightness, meanwhile, poor sealing phenomenon is easy to occur, and the accumulated tolerance of the assembled size of two machined parts is low in precision;
the rotor and the lower cover are cast into an integrated structure by adopting an iron casting process, 1 exists, and the production process is not environment-friendly; 2. the weight is too heavy and not light; 3. the cost is high;
the iron ring is embedded in the die and cast with aluminum alloy by adopting a die casting or casting process, so that the rotor and the lower end cover are cast into an integrated structure, 1 exists, and the production part is environment-friendly; 2. the energy consumption and the cost are high; 3. the disadvantage of the poor sealing is easily caused by the fact that the center of the lower cover needs to be perforated for casting exhaust, which requires 2 times of sealing.
Disclosure of Invention
In view of the above, the utility model provides an outer rotor lower cover shell applied to an industrial ceiling fan permanent magnet motor, which is reasonably designed in a targeted manner according to the applied technical parameters, and aims at saving cost, reducing weight, improving tightness and improving machining precision, and solving the problems of high manufacturing process cost, insufficient tightness, high energy consumption of component process, overweight weight, high machining rebound resilience and insufficient production efficiency.
The utility model provides an outer rotor lower cover shell applied to an industrial ceiling fan permanent magnet motor, which comprises an integrated stretching steel ring and a bearing seat, wherein the integrated stretching steel ring is barrel-shaped, the bearing seat is positioned in the integrated stretching steel ring, a reinforcing outer ring is arranged on the integrated stretching steel ring, and the reinforcing outer ring is connected with a rotor.
Preferably, the integral stretching steel ring is formed by stretching a cold-rolled plate through a press and a die.
Preferably, one end, far away from the bearing seat, of the integrated stretching steel ring is provided with a plurality of threaded holes, and the threaded holes are located on the integrated stretching steel ring and are distributed linearly in a circumferential mode.
Preferably, the reinforcing outer ring is located at one end of the integrated stretching steel ring far away from the bearing seat.
