Description

Technical Field

[0001] The utility model relates to the technical field of stator and rotor punching sheets, in particular to a seismic-resistant stator and rotor punching sheet assembly structure. Background Art

[0002] The motor rotor is the rotating part inside the motor, which is made of stacked silicon steel sheets. There are short-circuit rings at both ends of the rotor, which is the mechanism for outputting power from the motor. The motor stator is the fixed part inside the motor, which is made of stacked silicon steel sheets and is embedded with coil windings. The windings generate a rotating magnetic field to drive the rotor to rotate. The punching sheets are silicon steel sheets, which are punched from 0.3mm silicon steel sheets into punching sheets of different specifications to suit the stators and rotors of motors of different powers. The stator is used to generate an excitation magnetic field, which exerts a force on the energized conductors therein. There are armature windings in the rotor slots. When the armature windings are energized, they will rotate under the action of excitation and rotate with load through the rotating shaft.

[0003] At present, most stators and rotors have poor seismic resistance. During use, they are prone to wear, which reduces the service life of the components and is not convenient for long-term use. In addition, the cross-section of the stator and rotor punchings is small for the slot part and is severely stretched. When the material is sheared, the material rubs against the side of the mold, which will also cause the slot and the bottom of the slot to be stretched, resulting in warping of the punching. The more slots there are, the longer the slot shape is, and the narrower the slot is, the more serious the warping of the punching. In addition to transmitting vertical shear force, the stator and rotor punchings must also transmit unbalanced bending moment, and unbalanced bending moment will also be generated under the action of their own gravity. Therefore, a seismic-resistant stator and rotor punching assembly structure is needed to improve the above problems. Utility Model Content

[0004] In order to solve the problem that most of the current stators and rotors have poor seismic resistance, they are prone to wear during use, thereby reducing the service life of the components and making them inconvenient for long-term use. In addition, the cross-section of the stator and rotor punchings is small at the notch part and is severely stretched. When the material is sheared, the material rubs against the side of the mold, which will also cause the notch and the bottom of the groove to be stretched, resulting in warping of the punchings. The more slots there are, the longer the slot shape is, and the narrower the notch is, the more serious the warping of the punchings is. In addition to transmitting vertical shear force, the stator and rotor punchings must also transmit unbalanced bending moment, and unbalanced bending moment will also be generated under the action of their own gravity. The purpose of this utility model is to provide a seismic-resistant stator and rotor punching assembly structure to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A seismic-resistant stator and rotor punching assembly structure includes a connecting assembly, a protective seismic-resistant assembly is provided on the side of the connecting assembly, and an end assembly is provided on the side of the protective seismic-resistant assembly;

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the present invention, the overall seismic performance is increased by utilizing punching reinforcement rings and slab-column node rings. The hysteresis performance, stiffness, ductility and energy dissipation capacity of the slab-column node ring are significantly weakened with the increase of the weight-shear ratio, and are enhanced with the improvement of the reinforced plate. The reinforced plate mainly affects the stiffness value during the loading process. The predicted results of the punching shear bearing capacity of the slab-column node ring are still safe, and the calculated results of the unbalanced bending moment bearing capacity are generally safe, while reducing their discreteness.

In the utility model, the tensile stress generated by the stretching ring plate and the grooved ring plate is used to offset the compressive stress generated around the rotor body when it is impacted. At the same time, the compressive force generated around the grooved ring plate can be avoided when it is impacted, so that the punching piece will not warp. In combination with the inclined punch ring plate, the direction of the force acting on the material can be changed when it is impacted, so the punching piece will not warp.

The hysteresis performance, stiffness, ductility and energy dissipation capacity of the plate-column node ring 206 are significantly weakened with the increase of the shear ratio, and are enhanced with the increase of the reinforced plate 205. The reinforced plate 205 mainly affects the stiffness value during the loading process. The predicted result of the shear bearing capacity of the plate-column node ring 206 is still safe, and the calculation result of the unbalanced bending moment bearing capacity is generally safe, while its discreteness is reduced.

[0027] Among them, a protective tube 305 is provided inside the inclined punch ring plate 304, and a positioning ring 306 is fixedly connected to the side of the protective tube 305. The inclined punch ring plate 304 passes through the protective tube 305, and a positioning plate 209 is provided on the side of the rotating shaft 204. A connecting tube 303 is provided inside the inclined punch ring plate 304. The tensile stress generated by the stretching ring plate 302 and the grooved ring plate 301 is used to offset the compressive stress generated around the rotor body when it is impacted. At the same time, the compression force generated around the grooved ring plate 301 can be avoided when it is impacted, so that the punching piece will not warp. In combination with the inclined punch ring plate 304, the direction of the force acting on the material can be changed when it is impacted, so the punching piece will not warp.

[0028] In this embodiment, reference Figure 1 and Figure 2 As shown, the side of the insulating French pulling cylinder 201 is fixedly connected to a hollow frame 202, and the side of the hollow frame 202 is fixedly connected to a fixed disk 203. The connecting component 1 includes a connecting rod 101, and the connecting rod 101 is fixedly connected to a connecting shaft 102.

The side of the second clamping shaft 106 is fixedly connected to a disk rod 107, and a through hole 108 is opened inside the disk rod 107. The insulating French pulling cylinder 201 can effectively prevent heat from being transferred to the motor, thereby preventing the motor from being burned by heat.

[0029] In this solution, a seismic-resistant stator and rotor punching sheet assembly structure is used to clamp the first clamping shaft 104 and the second clamping shaft 106. When the motor drives the connecting rod 101 and the connecting shaft 102 to rotate, the disk rod 107 will be driven to rotate, and the through hole 108 is the position of the fixed rotating shaft 204, so the rotating shaft 204 will drive the punching sheet body 207, the punching steel bar ring 208 and the positioning plate 209 to rotate, that is, the inclined punch ring plate 304 and the positioning ring 306 to rotate.
