Description

Technical Field

[0001] This utility model belongs to the field of permanent magnet rotor installation, and specifically relates to an installation structure for permanent magnet rotors. Background Technology

[0002] Currently, a permanent magnet rotor is a type of rotor used in electric motors, comprising a rotor core and a rotor shaft. The rotor shaft passes through the shaft hole of the rotor core and is fastened together with the rotor core. Its characteristic is that a number of bosses are provided on the outer side of the rotor core, and a number of magnetic tiles are respectively fastened between two adjacent bosses.

[0003] For example, a permanent magnet synchronous motor rotor structure with application number "CN202321468693.8" relates to the field of motor technology. The device includes: a rotor yoke, permanent magnets, and rotor poles, with the rotor yoke and rotor poles connected by fastening screws; the rotor yoke includes a yoke body, screw holes, shaft holes, a step accommodating the screw holes, a transverse mounting surface for the permanent magnets, and a longitudinal limiting surface for the permanent magnets; the rotor poles include a pole, a hole, a rotor surface, a transverse mounting surface for the permanent magnets, and a longitudinal limiting surface for the permanent magnets; the screw holes and hole cooperate to position and fasten the rotor poles; the transverse mounting surfaces of the rotor yoke and rotor poles cooperate to press the permanent magnets laterally; the longitudinal limiting surfaces of the rotor yoke and rotor poles cooperate to limit the permanent magnets longitudinally. There is no gap between the permanent magnet and the rotor core, which improves the utilization rate of the permanent magnet; the rotor yoke and the magnetic pole are connected by bolts, which has a good magnetic isolation effect; the rotor magnetic pole is detachable, which facilitates the disassembly and assembly of the motor permanent magnet.

[0004] Based on the aforementioned patents and existing technologies, it is known that, when installing existing permanent magnet rotors, it is necessary to manually align and place multiple shims one by one in order to install the laminations in multiple permanent magnet rotors. However, this installation method results in low rotor installation efficiency because it requires manual alignment of each lamination.

[0005] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides an installation structure for permanent magnet rotors to solve the problem that the existing method requires manual alignment of multiple shims to install the laminations in multiple permanent magnet rotors. However, this installation method leads to low rotor installation efficiency because it requires manual alignment of each lamination. Utility Model Content

A longitudinally arranged cylindrical guide rod assembly is installed at the bottom end of the end plate mechanism. There are six guide rod assemblies in total. Each guide rod assembly has a threaded connector assembly fixedly connected to both its upper and lower sides. A nut assembly is screwed onto the outer side of each connector assembly. The bottom ends of the guide rod assembly and the connector assembly are connected to the bearing mechanism.

[0009] In a preferred embodiment, a guide component with an annular bearing seat structure is embedded inside the support component, and a longitudinally arranged transmission component is interference-fitted inside the guide component.

[0010] In a preferred embodiment, a ring-shaped bearing mechanism is welded and fixed to the outside of the transmission assembly, and the bearing mechanism has a ring array of positioning components B that are aligned with positioning component A.

[0011] In a preferred embodiment, an annular insertion component A is fixedly connected to the top surface of the bearing mechanism, and rotor laminations are sleeved on the outer side of the transmission component in a linear array.
