Embodiment 1

[0034] like figure 1 , figure 2 As shown, this embodiment provides a disk-type permanent magnet transmission device with a slotted back iron, which is used to transmit power between two shaft bodies. The two shaft bodies include the first shaft body 11 and the second shaft body 21 . The first shaft body 11 and the second shaft body 21 are coaxially arranged. The transmission device includes: a top plate 12 , a vortex plate 13 , a bottom plate 22 , and a fixing mechanism 3 .

[0035] please combine image 3 , in this embodiment, in order to facilitate installation, the shaft body 11, the top plate 12, the eddy current plate 13, the mounting plate 33, the bottom plate 22 and the middle part of the shaft body 2 21 are all provided with through holes, and a plurality of said The inner diameters of the through holes are all equal. The outer diameters of the top plate 12 , the vortex plate 13 , the mounting plate 33 and the bottom plate 22 are all equal. The top plate 12 is c...

Embodiment 2

[0046] see Figure 9 , This embodiment provides an installation method, and the installation method can be applied to the disk-type permanent magnet transmission device with the back iron slotted in the embodiment 1. The installation method includes:

[0047] Step S1 : first coaxially dispose the first shaft body and the top plate 12 , and then fix the first shaft body 11 and the top plate 12 by welding or other means.

[0048] Step S2: First, coaxially dispose the top plate 12 and the eddy current plate 13, and then fixedly connect the eddy current plate 13 and the top plate 12 by means of gluing or the like.

[0049] Step S3: firstly coaxially dispose the chassis 22 and the second axle body 21, and then fix the chassis 22 and the second axle body 21 by welding or other means.

[0050] Step S4: firstly, the plurality of auxiliary magnetic poles 34 are classified and embedded in the plurality of installation grooves 36 on the installation plate 33 at intervals, then the inst...

Embodiment 3

[0054] The difference between this embodiment and Embodiment 1 lies in that, on the basis of the existing structure of Embodiment 1, this embodiment is additionally provided with a casing. The shell includes: a first shell and a second shell.

[0055] The first shell and the second shell are arranged separately. Among them, the shaft body 11, the top plate 12 and the eddy current plate 13 can all be installed inside the casing one. The second shaft body 21 , the chassis 22 and the fixing mechanism 3 can all be installed inside the second casing. Shell 1 and shell 2 can also be made of light material with paramagnetic properties, which can protect the entire transmission device and the two shafts, which can prevent dust from entering the internal structure of the transmission device and prevent external objects from colliding with the internal structure. It can also reduce the degree of oxidation and aging of the internal structure of the transmission device, thereby prolongi...

Abstract

The invention relates to the technical field of transmission, in particular to a disk-type permanent magnet transmission device with a slotted back iron, which is used for transmitting power between two shaft bodies. The two shaft bodies include shaft body 1 and shaft body 2. The first shaft body and the second shaft body are arranged coaxially. The transmission device includes: top plate, eddy current plate, chassis, and fixing mechanism. The top plate is coaxially fixed on one side of the first shaft body. The vortex disk is coaxially fixed on the side of the top disk facing the second shaft body. The chassis is coaxially fixed on the two sides of the shaft body facing the first side of the shaft body. The fixing mechanism is arranged on the side of the chassis facing the first axle body. The fixing mechanism includes a mounting frame, a plurality of main magnetic poles, a mounting disk, and a plurality of auxiliary magnetic poles. The mounting plate is fixed on the side of the chassis facing the shaft body 1. One side of the mounting plate is provided with a first mounting groove, and the other side is provided with a plurality of mounting grooves two corresponding to the plurality of auxiliary magnetic poles in a circular arrangement of the central axis of the mounting plate. The invention effectively reduces the side magnetic leakage existing in the traditional disc magnetic coupling, thereby increasing the torque that the transmission device can transmit.

Description

technical field [0001] The invention relates to the technical field of transmission, in particular to a disk-type permanent magnet transmission device with a slotted back iron. Background technique [0002] Coupling refers to a device that connects two shafts or shafts and rotating parts, rotates together in the process of transmitting motion and power, and does not disengage under normal circumstances. The magnetic coupling is also used as a safety device to prevent the connected parts from being subjected to excessive load and cause the motor to stall, and play the role of overload protection. [0003] The existing disc magnetic coupling structure inevitably has side magnetic leakage. When the size of the coupling increases, the side magnetic leakage is more obvious, and the utilization rate of magnetic energy is reduced. SUMMARY OF THE INVENTION [0004] In view of the problems in the prior art, the present invention provides a disk-type permanent magnet transmission d...
