Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 2, the utility model discloses an integral type coreless shell body subassembly, which comprises an outer shell 1, the magnet steel 3 in the axle sleeve 2 outside is located to axle sleeve 2 and cover, shell 1 is equipped with the cavity, magnet steel 3 is located the cavity, the pore wall of mounting hole inwards stretches into in the cavity, axle sleeve 2 holds and locates in the mounting hole and run through magnet steel 3, magnet steel 3 and the pore wall of mounting hole stretched into in the cavity, axle sleeve 2's both ends are provided with first snap ring 21 and second snap ring 22 respectively, one side of magnet steel 3 is kept away from to the pore wall of mounting hole is located to first snap ring 21 card, second snap ring 22 card is located one side that magnet steel 3 kept away from the pore wall of mounting hole, axle sleeve 2 runs through and is.
As shown in fig. 1 and 2, the bearing 4 and the bearing 4 sleeve are used in the conventional hollow cup structure, and the rotor assembly is arranged in the bearing 4 in a penetrating manner, so that the assembly is realized, and the assembly needs more parts, is complex in structure and is long in assembly time. The utility model discloses an integral type coreless shell, shell 1 is provided with the mounting hole, the pore wall butt of magnet steel 3 and mounting hole, mounting hole and magnet steel 3 are worn to establish in proper order by axle sleeve 2, and axle sleeve 2's both ends are provided with first snap ring 21 and second snap ring 22 respectively, first snap ring 21 is fixed magnet steel 3 with the pore wall respectively with second snap ring 22 and is in the same place to make magnet steel 3 realize fixedly with shell 1, simple structure, the equipment is simple and convenient, the structure is more firm, and stability is better.
