Embodiment 1

[0043] refer to Figure 1-Figure 4 , the cylindrical self-adjusting air gap permanent magnet soft connection device provided in this embodiment includes:

[0044] The first connecting shaft 1 is suitable for connecting a load;

[0045] The second connecting shaft 2 is suitable for connecting and driving and is coaxial with the first connecting shaft 1;

[0046] The conductor rotor 3 includes a conductor ring 31 and a cylindrical conductor ring carrier 32, the conductor ring carrier 32 is relatively fixed on the first connecting shaft 1, and the conductor ring 31 is fixed on the inner wall of the conductor ring carrier 32 above; as known to those skilled in the art, the conductor ring carrier 32, the conductor ring 31 and the first connecting shaft 1 are coaxial; the so-called cylindrical shape is a hollow columnar structure with openings at both ends; "relatively fixed" can be fixed directly or through The connecting piece is indirectly fixed on the first connecting shaft 1,...

Embodiment 2

[0075] refer to Figure 5 , the difference between the present embodiment and the first embodiment is only that the installation structure of the elastic member 45 is different, as follows:

[0076] The end face of the second connecting shaft 2 close to the first connecting shaft 1 is sealed and a connecting portion 221 protrudes from the middle, the elastic member 45 is a tensile elastic member, and one end of the elastic member 45 is connected to the carrier block 411 , and the other end of the elastic member 45 is connected to the connecting portion 221 . The tensile force of the elastic member 45 drives the carrier block 411 close to the second connecting shaft 2 , thereby hindering the radial outward movement of the carrier block 411 .

Embodiment 3

[0078] refer to Figure 6-Figure 7 , the difference between the present embodiment and the first embodiment is only that the installation structure of the elastic member 45 is different, as follows:

[0079] The elastic member 45 is a tensile elastic member, and two ends of the elastic member 45 are respectively connected to two adjacent carrier blocks 411 . The tensile force of the elastic member 45 drives two adjacent carrier blocks 411 close to each other. Since the carrier blocks 411 are slidably mounted on the second connecting shaft 2, the carrier blocks 411 will be driven close to the second connecting shaft 2, thus hindering the carrier blocks. 411 moves radially outward.

[0080] Above-mentioned three embodiments have provided three kinds of different installation structures of elastic member 45, and in other embodiments, elastic member 45 can be compression elastic member also can be tension elastic member; Elastic member 45 can adopt such as figure 1 or Figure 5...

Abstract

The invention relates to the technical field of mechanical transmission, in particular to a barrel type permanent magnet flexible connection device with an air gap self-adjusting function. The device comprises a first connecting shaft suitable for being connected with a load, a second connecting shaft, a conductor rotor, and apermanent magnet rotor. The second connecting shaft is suitable for being connected with a driver and is coaxial with the first connecting shaft; the conductor rotor comprises a conductor ring and a cylindrical conductor ring carrier, the conductor ring carrier is relatively fixed on the first connecting shaft, and the conductor ring is fixed on the inner wall of the conductor ring carrier; the permanent magnet rotor is located between the conductor ring and the second connecting shaft and is coaxial with the conductor ring, the permanent magnet rotor comprises a permanent magnet carrier, the permanent magnet carrier comprises at least two carrier blocks which are evenly distributed in the circumferential direction of the second connecting shaft, and the carrier blocks are installed on the second connecting shaft and can slide in the radial direction of the second connecting shaft; the surface, facing the conductor ring, of each carrier block is fixedly provided with a permanent magnet, and each carrier block is connected with an elastic piece suitable for preventing the carrier block from sliding outwards in the radial direction. By adopting the scheme, the air gap can be automatically adjusted during starting, the structure is simple, the weight is light, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of permanent magnet couplers, in particular to a cylindrical self-adjusting air gap permanent magnet soft connection device. Background technique [0002] In order to solve the problem of excessive starting torque, a hydraulic coupling or soft starter is generally added between the motor and the load. The hydraulic coupling can delay the start-up time of the motor and slow down the start-up impact, but it has the problems of low efficiency, oil leakage and large space occupation; the conventional soft starter can realize the soft start of the system, but all require a special control system, Complex structure and inconvenient maintenance. [0003] For this reason, a permanent magnetic coupler specially designed to solve the above problems has been developed on the market. Existing permanent magnetic couplers mainly include disc permanent magnetic couplers and barrel permanent magnetic couplers. There is a...
