Rotor sheet of reluctance motor

Abstract

The utility model provides a rotor sheet of a reluctance motor, which relates to the technical field of rotor sheets and comprises a rotor sheet main body. Through the arrangement of the auxiliary part, on one hand, when the rotor sheet main body is unbalanced, the weight balance adjustment of the rotor sheet main body can be realized by increasing or reducing screws at local positions; due to the fact that the adjusting groove is formed in the screw rod, after the adjusting position of the screw rod is damaged, an internal hexagonal wrench can be used for being inserted into the adjusting groove for adjustment, and practicability is high. As the top end face of the auxiliary seat is 0.3 cm lower than the top end face of the screw rod, after a plurality of rotor sheet main bodies are assembled, the screw rod can be prevented from loosening through extrusion of the rotor sheet main bodies, the auxiliary seat cannot influence the extrusion of the upper rotor sheet main body on the lower screw rod, the practicability is high, and the problem that in the using process of an existing rotor sheet, when the self weight of the rotor sheet is not balanced enough, the screw rod cannot be loosened is solved. And in the use process after assembly, the vibration amplitude in the rotation process of the motor is too large, and the normal use of the motor is influenced.

Description

Technical Field

[0001] The utility model relates to the technical field of rotor sheets, in particular to a rotor sheet of a reluctance motor. Background Art

[0002] A rotor refers to a rotating body supported by bearings; an object that does not have its own rotating axis, such as a CD, can be considered a rotor when it uses a rigid connection or an additional shaft. The rotor is equipped with multiple rotor plates, which are made of metal.

[0003] When the weight of the existing rotor plates is not balanced enough during use, it is easy to cause excessive vibration amplitude during the rotation of the motor during use after assembly, thus affecting the normal use of the motor. Utility Model Content

[0004] In view of this, the utility model provides a rotor plate of a reluctance motor, which solves the problem that when the weight of the existing rotor plate is not balanced enough during use, it is easy to cause excessive vibration amplitude during the rotation of the motor during use after assembly, thereby affecting the normal use of the motor.

[0005] The purpose and effect of the rotor piece of a reluctance motor of the utility model are achieved by the following specific technical means:

[0006] The utility model provides a rotor sheet of a reluctance motor, which specifically comprises: a rotor sheet main body; the rotor sheet main body is a circular plate-shaped structure, and the rotor sheet main body is made of iron material.

[0007] Furthermore, a connection hole for connecting with the rotor shaft is provided on the top surface of the rotor sheet body, and a limiting groove is provided on the inner wall of the connection hole. The limiting groove is a rectangular groove structure and is a positioning key insertion groove.

[0008] Furthermore, the rotor plate body is provided with first cooling holes in an annular array, and the first cooling holes provided in an annular array together constitute a cooling structure and a weight reduction structure of the rotor plate body.

[0009] Furthermore, the rotor sheet main body is provided with second cooling holes in an annular array, and the second cooling holes are circular hole structures. The second cooling holes provided in an annular array together constitute a second cooling structure and a weight reduction structure of the rotor sheet main body. During use, the rotor sheet main body can be cooled by the first cooling holes and the second cooling holes, and after the first cooling holes and the second cooling holes are opened, the weight of the rotor sheet main body can be reduced, thereby saving energy consumption.

[0010] Furthermore, an auxiliary part is provided on the rotor sheet body, and the auxiliary part is composed of a threaded hole, a screw and an adjustment groove. Sixty threaded holes are opened in a circular array on the rotor sheet body, and the sixty threaded holes together constitute the weight reduction structure of the rotor sheet body.

[0011] Furthermore, each of the threaded holes is threadedly connected to a screw rod, and the threaded hole and the screw rod together constitute a weight adjustment structure of the rotor sheet body. When the rotor sheet body is overweight, the weight balance of the rotor sheet body can be achieved by adding or reducing the screw rods at local positions.

[0012] Furthermore, the adjustment portion of the screw is a hexagonal structure, and an adjustment slot is provided at the adjustment portion of the screw. The adjustment slot is a hexagonal slot structure, and the adjustment slot is an auxiliary adjustment part of the screw. When the adjustment portion of the screw is damaged, an hexagonal wrench can be inserted into the adjustment slot for adjustment.

[0013] Furthermore, an auxiliary seat is welded to the top surface of the rotor sheet body. The auxiliary seat is an annular structure. The auxiliary seat covers the outside of the screw. The top surface of the auxiliary seat is 0.3 cm lower than the top surface of the screw. During use, when multiple rotor sheet bodies are assembled, the screw can be prevented from loosening by squeezing the rotor sheet bodies. When rotating, the contact effect between air and the screw can be reduced by blocking the auxiliary seat, thereby reducing wind resistance and saving energy.

[0014] Beneficial Effects

[0015] An auxiliary part is provided. Through the provision of the auxiliary part, on the one hand, when the rotor sheet body is overweight, the weight balance of the rotor sheet body can be adjusted by adding or reducing the screw rods at the local position. Because an adjustment groove is provided on the screw rod, when the adjustment part of the screw rod is damaged, an Allen wrench can be inserted into the adjustment groove for adjustment, which is highly practical.

[0016] An auxiliary seat is provided. Through the setting of the auxiliary seat, on the one hand, the contact effect between air and the screw can be reduced through the blocking of the auxiliary seat, thereby reducing wind resistance and saving energy consumption; on the other hand, because the top surface of the auxiliary seat is 0.3 cm lower than the top surface of the screw, when multiple rotor sheet bodies are assembled, the screw can be prevented from loosening through the extrusion of the rotor sheet bodies, and the auxiliary seat will not affect the extrusion of the lower screw by the upper rotor sheet body, and the practicality is high.

[0017] A first cooling hole and a second cooling hole are provided, through which the cooling of the rotor sheet main body can be achieved, and after the first cooling hole and the second cooling hole are opened, the weight of the rotor sheet main body can be reduced, thus saving energy consumption and having high practicality. By reducing weight through the two weight-reducing structures of the first cooling hole and the second cooling hole, the weight-reducing effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
