And the steps of manual operation are greatly simplified.

The utility model provides a novel stator structure, and belongs to the field of motors. The problem that vibration noise is easily generated when an existing inner rotor rotates in a stator is solved. The novel stator structure comprises a stator body with a shaft hole, a plurality of opening type stator grooves are uniformly distributed in the inner circumference of the shaft hole in the circumferential direction, each groove body adopts a radial opening design, the stator body is divided into a plurality of independent stator winding blocks through the stator grooves distributed at intervals, and vibration buffering devices are arranged on the inner circumference surfaces of the shaft holes of the stator winding blocks. The vibration buffering device comprises a movable groove, an elastic protection plate and a rolling assembly, the movable groove is located in the inner circumferential surface of a shaft hole of the stator winding block, mounting pillow blocks are arranged on the two axial sides of the movable groove, and the inner arc face of the elastic protection plate and the shaft hole are kept concentric. And each pin roller is movably mounted in a T-shaped movable cavity formed by matching the elastic protection plate and the mounting plummer block through the bearing assemblies at the two ends. The shock absorber has the advantages of shock absorption and noise reduction.

This utility model relates to the field of support device technology and discloses a protective support device for the main shaft of a mining crusher, including two fixed plates and two load-bearing mechanisms. The top of each of the two fixed plates has a groove, and a hydraulic rod is fixedly installed on the inner bottom wall of each of the two grooves. A support mechanism is fixedly installed on the top of each of the two hydraulic rods. This protective support device for the main shaft of a mining crusher, through the hydraulic rods, can quickly raise the support mechanism when the main shaft bearing fails, allowing the roller load-bearing mechanism to form rolling contact support with the main shaft, replacing the load-bearing function of the failed bearing. This structure avoids rigid friction between the main shaft and the bearing seat, effectively preventing secondary damage such as wear of the main shaft journal and damage to the bearing seat. Through the interlocking action of the toothed plate and toothed seat in the support mechanism, the distance between the two rollers can be easily adjusted, thus adapting to main shafts of different diameters and improving the applicability of the device.
