A single-rotor disc applied to a disc motor

Abstract

The invention discloses a single-rotor disk applied to a disk-type motor, which includes a mounting disk, in which several groups of mounting holes distributed in a circular array are arranged, and each group of mounting holes is provided with aligned magnetic steel pressing blocks. Magnetic steel is arranged between adjacent magnetic steel pressing blocks; both sides of the magnetic steel pressing block are respectively provided with pressing surfaces, and both sides of the magnetic steel are respectively provided with mating surfaces capable of matching the pressing surfaces. The advantage of the present invention is that the magnetic steel bracket is converted into a magnetic steel briquetting block, the positioning accuracy between the magnetic steel briquetting blocks is not related, and no over-positioning is formed, thereby reducing the accuracy requirement required for the assembling of the magnetic steel, and the magnetic steel briquetting The pressing block presses the magnetic steel to ensure the assembly stability and accuracy of the magnetic steel, and improves the installation efficiency of the single rotor disc; The disk can be directly milled out of the installation groove by milling, which is more convenient for processing.

Description

technical field

[0001] The invention belongs to the field of disc motors, in particular to a single rotor disc applied to disc motors. Background technique

[0002] Disc motor, also known as disc motor, has the characteristics of small size, light weight and high efficiency. Generally, the rotor and stator of the motor are set inside and outside. The shape of the disc motor is thin. The stator adopts a flat base plate. Magnet magnets or rotor discs with permanent magnet magnets glued on. The existing assembled rotor disc structure has many problems.

[0003] For example, the Chinese patent document CN208158266U disclosed on November 27, 2018 "the fixed structure of the magnetic steel in the rotor assembly of the disc motor", including the rotor disc, a number of magnetic steels, and a cage. The surface of the rotor disc is provided with an annular groove. The outer ring of the groove is provided with gaps at intervals, and several magnetic steels are arranged in the annula...

Examples

Embodiment 1

[0027] Such as Figures 1 to 4 As shown, it is a single-rotor disk applied to a disk motor, including a mounting disk 1, an annular mounting groove 11 is provided inside the mounting disk 1, and an upwardly protruding annular flange is provided on the inner and outer edges of the mounting groove 11 The shape of the inner ring 12 of the installation groove 11 is a regular polygon, and the shape of the outer ring 13 of the installation groove 11 is a circle. The mounting groove 11 can be directly formed by milling a cylinder. The mounting plate 1 is provided with ten sets of mounting holes 14 distributed in a circular array, the mounting holes 14 are located in the mounting groove 11 and the array axis of the ten sets of mounting holes 14 is the axis of the mounting plate 1 . Each set of mounting holes 14 is provided with aligned magnetic steel pressure blocks 2 , and a single set of mounting holes 14 includes two threaded holes, and the two threaded holes are located in the ra...

Embodiment 2

[0029] Such as Figure 5 As shown, the difference between embodiment 2 and embodiment 1 is that the pressing surface 21 is a bent stepped surface. Therefore, the mating surface 31 is a stepped surface mated with the pressing surface 21 . After the steel briquetting block and the magnetic steel 3 are mated, the matching accuracy of the end faces is low. Even if there is a processing error, the magnetic steel 3 will not move in the magnetic steel briquetting block 2, which is more convenient for assembly and has high stability.

Embodiment 3

[0031] Such as Figure 6 As shown, the difference between Embodiment 3 and Embodiment 1 lies in that four protruding rack pieces 22 are arranged in the pressing surface 21 . The rack plate 22 is a strip-shaped sheet structure, and the four rack plates 22 are equal and arranged in parallel, and the rack plates 22 are parallel to the bottom side of the magnetic steel pressing block 2; the adjacent rack plates 22 are on the pressing surface 21 The distance above is equal to the width of the rack plate 22. The rack piece 22 forms an outwardly convex elastic structure, which can be made of softer material than the magnetic steel. When there is a gap between the magnetic steel briquetting block 2 and the magnetic steel 3 due to processing errors, the rack piece 22 is bent to fill the pressure. The gap between the tight surface and the matching surface can assist the compression of the magnetic steel briquetting block 2 .
