Description

Magnetic coupling technology

The invention relates to a magnetic coupling, in particular to a magnetic coupling capable of adjusting the spacing of the guiding disks.

Background technique

At present, countries all over the world are actively addressing the issue of energy demand. In addition to finding alternative energy sources, it is to improve the operational efficiency of various connected institutions. The place where power loss is most likely to occur is where the components are connected to the components, such as: couplings. A coupling is a mechanical assembly that uses components to connect two different machines so that the two shafts can rotate together during the transmission process as a bridge that drives each other. However, during the process of transmission and rotation, the components are affected by factors such as friction and component characteristics, resulting in loss of power.

In order to reduce the above-mentioned power loss condition, there is currently a coupling that utilizes magnetic force as power transmission, which is mainly composed of a conductive disk and a permanent disk, and uses magnetic characteristics to make the two achieve the effect of linkage, and as Power transmission is used. Since the transmission method does not directly contact, the magnetic coupling machine has less loss in operation than the conventional coupling machine, and has energy saving effect.

However, the permanent magnet coupling structure is known, and there are still disadvantages in practical application. The disadvantage is that the spacing adjustment of the two-conductor disk in the permanent magnet coupling machine is not easy, and one of the main factors affecting the transmission efficiency of the permanent magnet coupling machine lies in the spacing between the conductive disk and the permanent disk (ie, the air gap). The distance between each lead disk and the permanent disk must be within a certain range, so as to achieve the best stress effect. However, in the process of adjustment, the known technology is mainly in the form of single-chip movement, which may cause the spacing between the two-conductor disk and the permanent disk in the middle to be inconsistent, or the distance needs to be re-calibrated by other means, so After many adjustments, a lot of time will be wasted in this step.

Summary of the invention

In view of the above problems, the present invention provides a magnetic coupling capable of stably adjusting an air gap between a conductive disk and a permanent magnetic disk, and by moving the two conductive disks inward or outward at the same time, maintaining each The gap between the conductive disk and the permanent disk is the same, which overcomes the problem that the adjustment of the prior art is not easy.

The magnetic coupling of the present invention comprises an adjustable disk group and a permanent disk group. The adjustable conductive disk group includes a two-conductor disk, a connecting disk and at least one spacing adjustment mechanism.

The spacing adjustment mechanism is disposed on the lands and connected to the guiding disks for controlling the spacing between the two guiding disks. The permanent disk group contains a permanent disk, a majority of magnets and an auxiliary disk. The permanent disk is ring-shaped and disposed on the periphery of the lands, and includes a first surface and a second surface. Most of the magnets are centered on the center of the permanent disk, and are arranged in a radial arrangement on the permanent disk, and the magnets are exposed on the first side and the second side of the permanent disk. The auxiliary disk is connected to the permanent disk via at least two connection blocks, and is located outside one of the conductive disks. The invention synchronously changes the relative position of the two-conducting magnetic disk through the spacing adjustment mechanism, that is, changes the air gap between the permanent magnetic disk and the air gap of the permanent magnetic disk during the adjustment process, and the air gap of the permanent magnetic disk and the permanent magnetic disk are always kept equal, and no need to be separately adjusted to overcome the It is known that the problem of adjusting the air gap is not easy, and the present invention has the effect of simple and quick operation. The invention utilizes the spacing adjustment mechanism to make the two-lead disk move the same stroke inward or outward at the same time, stably adjust the air gap between the conductive disk and the permanent disk, and achieve the same effect as the known technology by using only one permanent disk. , Overcoming the problem that the adjustment of the known technology is not easy and the volume is too large.

Thereby, the stability of the guide disk movement can be improved.

Preferably, the number of the mobile auxiliary mechanisms may be three or more, and the distances of the adjacent mobile auxiliary mechanisms are the same. By this, the guide disk can be moved without shaking or changing the angle.

The racks are respectively engaged with the gears, and they are respectively connected to one of the guide disks. Thereby, the guide disk can be stably moved.

detailed description

Please refer to Figure 1 to Figure 3. The magnetic coupling of this embodiment includes an adjustable disk group 10 and a permanent disk group 20. In addition, in the embodiment of Fig. 1, the embodiment is connected to a body, which is not a necessary component, and is only one of the modes of use, so as to avoid causing doubt, it will be described first.

As shown in FIG. 2, the adjustable conductive disk group 10 includes a two-conducting magnetic disk 11, a connecting disk 12 and at least one pitch adjusting mechanism 13. The guide disks 11 are arranged in parallel with each other at intervals, and each of the guide disks 11 is provided with a guide shaft connecting hole 111. The lands 12 are disposed in parallel between the guide disks 11 and define a lands connecting shaft 121, the center of which corresponds to the center of the guide shaft connecting holes 111. The guide shaft connecting hole 111 and the connecting rod shaft connecting hole 121 can be connected to other bearings for power transmission. The spacing adjustment mechanism 13 is disposed on the lands 12 and connected to the conductive disks 11 for controlling the spacing between the conductive disks 11.

The permanent disk group 20 includes a permanent disk 21, a plurality of magnets 22 and an auxiliary disk 23. Wherein, the permanent disk 21 is in a ring shape, and It includes a first face 211 and a second face 212. The magnets 22 are centered on the center of the permanent magnetic disk 21, and are arranged in a radial arrangement on the permanent magnetic disk 21, and the magnets 22 are exposed on the first surface 211 and the second surface 212 of the permanent magnetic disk 21. The auxiliary disk 23 is connected to the permanent disk 21 via at least two connection blocks 231, and is located outside one of the conductive disks 11.

By the arrangement of the spacing adjustment mechanism 13, the conductive disk 11 is kept at the same distance from the permanent disk 21 in the process of adjusting the position, so as to achieve the effect of quickly adjusting the air gap, thereby overcoming the problem that the known technology must be repeatedly measured. .

Moreover, since the magnets 22 on the permanent magnetic disk 21 are directly exposed on the first surface 211 and the second surface 212, the two poles of each of the magnets 22 can be fully utilized, and the thickness of the permanent magnetic disk 21 is thinner than the thickness of the known permanent magnetic disk. . In addition, the permanent disk 21 can interact with the two-conductor disk 11 in only one piece, and the disadvantage that the known two-permanent disk and the two-conducting disk are excessively bulky is improved, which contributes to the overall volume reduction.

Since the pitch adjustment mechanism 13 can be in several forms, one example will be given below, but not limited thereto. Referring to Figures 4 to 10, the pitch adjustment mechanism 13 includes a gear 131 and two racks 132. The gears 131 are embedded in the lands 12, and the racks 132 are respectively engaged with the gears 131, and are respectively connected to one of the guide disks 11. Therefore, when one of the guide disks 11 moves, the gear 131 will be rotated through the connected rack 132, and at the same time, the other rack 132 will be moved by the gear 131, thereby pushing or pulling the other guide disk 11 The role. Moreover, by the arrangement of the gear 131 and the rack 132, the effect of generating the same distance of displacement can be achieved. Of course, in addition to the application of the gear and the rack, the same effect can be achieved by the setting of the link mechanism.

As shown in Fig. 5, the number of the pitch adjusting mechanisms 13 may be three or more, and the pitch of each adjacent pitch adjusting mechanism 13 is the same. Therefore, the guide disk 11 is biased so that the guide disk 11 does not become skewed during the movement.

Referring to FIG. 9 and FIG. 10, the movement assisting mechanism 14 is disposed on the lands 12 and includes at least two sliding grooves 141 and two sliding blocks 142. These sliders 142 are respectively inserted into one of the chutes 141 and respectively connected to a guide disk 11, and these sliders 142 can be moved in parallel. By the slider 142 being restrained by the chute 141 in a state of being horizontally movable only, the guide disk 11 can be more stable and smooth during the movement.

Further, as shown in Fig. 10, the number of the movement assisting mechanisms 14 may be three or more, and the distance between each adjacent the movement assisting mechanism 14 and the distance from the center of the land 12 are the same. With this arrangement, the guide disk 11 can be made smoother when moving, and due to its equal position setting, the guide disk 11 does not tilt during the movement, and the force distribution of the guide disk 11 can be made. On average, the movement of the disk 11 will be smoother. In addition, the sliders 142 can be made in a cylindrical shape to make the overall operation smooth.

In addition, as shown in FIG. 2, a plurality of heat sinks 112 are disposed on the conductive disks 11 to assist the conductive disks 11 to dissipate heat. Further, these magnets 22 are in the form of a block, so that when the whole body is operated, when the magnet 22 is pushed against the permanent disk, a large area can transmit the force. The magnetic poles of adjacent magnets 22 are opposite in position.

Further, as shown in Fig. 2, the auxiliary disk 23 further defines an auxiliary disk shaft connecting hole 232 which corresponds to the center of the wire connecting hole of the disk, so that the loss can be reduced when the force is transmitted.

The embodiments described above are merely illustrative of the technical idea and features of the present invention, and the purpose thereof is to enable those skilled in the art. It is to be understood that the scope of the present invention is not limited by the scope of the invention, and that the equivalents and modifications of the invention are intended to be included within the scope of the invention.
