Description

Technical Field

[0001] This invention relates to a magnetic coupling, and more particularly to a component for forming a magnetic coupling and the magnetic coupling itself. Background Technology

[0002] A coupling is a mechanical component used to connect two shafts (driving end and driven end) in different mechanisms, enabling them to rotate together and transmit torque. Magnetic couplings are a special type, belonging to the non-contact coupling category. They generally consist of two magnets, an inner magnet connected to the driven component and an outer magnet connected to the driving component. In operation, magnetic couplings transmit force and torque without direct contact between the driving and driven ends.

[0003] A magnetic coupling, as disclosed in Chinese Patent Publication No. CN222940686U, includes a first rotating component (10), a second rotating component (20), and a magnetic adjustment mechanism. The first rotating component has several first magnets (12) arranged around a first axis (R1). The second rotating component has several second magnets (22) arranged around a second axis (R2). The second rotating component is spaced apart from the first rotating component, and the first and second axes are parallel or overlap. When one of the first and second rotating components rotates, the magnetic force between the first and second magnets can drive the other rotating component to rotate synchronously. The magnetic adjustment mechanism can adjust the magnitude of the magnetic force between the first and second magnets. This magnetic coupling can be used with a motor to adjust the load, shorten the motor's start-up acceleration time, reduce the motor's start-up temperature, and protect the motor. However, this patent has the following problems: Magnetic drives are mainly used to avoid prolonged high loads on motors. However, for equipment that requires high initial loads, such as crushers, the motor needs to be started using a delta starter to increase torque. But the coupling will limit the high torque output in the early stages, making the magnetic coupling unable to adapt to the starting of high-load equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a component for forming a magnetic coupling and a magnetic coupling, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a component for forming a magnetic coupling and a magnetic coupling, comprising a magnet base and a power mechanism. Two magnet bases are provided, and a magnet is embedded in the end of each magnet base. A second transmission shaft is fixedly connected to one side of one of the magnet bases. A transmission sleeve is slidably mounted on the second transmission shaft. A second connecting flange is fixedly connected to the other end of the transmission sleeve. An adjustment mechanism is connected between the second transmission shaft and the transmission sleeve. The adjustment mechanism includes a first bearing and a second bearing. The first bearing is sleeved on the transmission sleeve, and the second bearing is sleeved on the second transmission shaft. A fixed seat is fixedly connected below the first bearing. An adjustment motor is fixedly connected to one side of the fixed seat. A telescopic adjustment rod is fixedly connected to the output end of the adjustment motor. The other end of the telescopic adjustment rod is fixedly connected to the adjustment seat.

[0006] Preferably, a first drive shaft is fixedly connected to one side of another of the magnet seats, and a first connecting flange is fixedly connected to the other end of the first drive shaft.

[0007] Preferably, the outer wall of the second drive shaft has symmetrically formed limit grooves.

[0008] Preferably, the inner wall of the transmission sleeve is symmetrically fixed with limiting protrusions, and the limiting protrusions are slidably engaged with the limiting grooves.

[0009] Preferably, a mounting bracket is fixedly connected to one side of the fixed base, and the other end of the mounting bracket is fixedly connected to the power mechanism.

[0010] Preferably, a plurality of telescopic connecting rods are fixedly connected between the fixed seat and the adjusting seat, and the plurality of telescopic connecting rods are arranged in a row and evenly surround the adjusting screw.

[0011] Preferably, the telescopic adjusting rod includes an adjusting screw and a threaded sleeve, with one end of the adjusting screw fixedly connected to the output end of the adjusting motor.

[0012] Preferably, the other end of the threaded sleeve is fixed to one side of the adjusting seat, and the threaded sleeve is threadedly engaged with the adjusting screw.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The distance between the two magnet seats can be controlled by adjusting the mechanism, so that the distance between the two magnet seats is reduced, the torque transmission of the coupling is increased, and the coupling can start under high load in the early stage of the load equipment, avoiding the problem that the coupling cannot achieve power transmission when the load equipment is difficult to start in the early stage.

[0014] 2. By sliding the limiting groove and the limiting protrusion, the second drive shaft can only move inside the first connecting flange, avoiding the problem of relative rotation between the first connecting flange and the second drive shaft, allowing one magnet seat to move and adjust the distance between the two magnet seats.

[0015] 3. The telescopic connecting rod is used to connect the fixed seat and the adjusting seat, so that the fixed seat and the adjusting seat are on the same horizontal plane, and at the same time bear the lateral torque, avoiding the problem of bending of the adjusting screw and threaded sleeve.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0020] Example 1 A component for forming a magnetic coupling and a magnetic coupling include a magnet base 1 and a power mechanism 9. Two magnet bases 1 are provided, with a magnet embedded at one end of each magnet base 1. A second drive shaft 103 is fixedly connected to one side of one magnet base 1. A drive sleeve 2 is slidably mounted on the second drive shaft 103. A second connecting flange 202 is fixedly connected to the other end of the drive sleeve 2. An adjustment mechanism 3 is connected between the second drive shaft 103 and the drive sleeve 2. The adjustment mechanism 3 includes a first bearing 301 and a second bearing 302. The first bearing 301 is sleeved on the drive sleeve 2, and the second bearing 302 is sleeved on the second drive shaft 103. A fixed seat 303 is fixedly connected below the first bearing 301. An adjustment motor 304 is fixedly connected to one side of the fixed seat 303. A telescopic adjustment rod is fixedly connected to the output end of the adjustment motor 304. The other end of the telescopic adjustment rod is fixedly connected to the adjustment seat 307.

[0021] In this embodiment, the output end of the power mechanism 9 is fixed to the limiting protrusion 201 via a flange, thereby enabling the power mechanism 9 to drive the transmission sleeve 2 to rotate. The transmission sleeve 2 then drives the second transmission shaft 103 and the magnet base 1 to rotate. The magnet base 1 can drive another magnet base 1 to rotate. The first connecting flange 102 connects to the load device, thus transmitting power to the load device. If the load is too high during startup and exceeds the normal torque transmission between the magnet bases 1, the extension of the telescopic adjustment rod can be adjusted using the adjusting motor 304. The telescopic adjustment rod will push the second transmission shaft 103 to move, allowing the second transmission shaft 103 to engage with the transmission sleeve 2. The transmission rod composed of sleeve 2 becomes longer, thereby reducing the distance between the two magnet seats 1 and increasing the torque transmission of the coupling. At the same time, due to the change in the optimal air gap between the two magnet seats 1, vibrations and other phenomena will occur during the transmission process, which is normal. This is suitable for the initial low-speed rotation process of the load equipment during the initial start-up. After the load equipment has started normally, it is necessary to control the adjustment motor 304 to drive the second transmission shaft 103 to reset, so that the air gap between the magnet seats 1 returns to the optimal state. This allows the coupling to start under high load during the initial start-up of the load equipment, avoiding the problem of the coupling being unable to transmit power when the load equipment is difficult to start.

[0022] Example 2 Another magnet base 1 has a first drive shaft 101 fixedly connected to one side, and a first connecting flange 102 fixedly connected to the other end of the first drive shaft 101. The outer wall of the second drive shaft 103 is symmetrically provided with limiting grooves 104, and the inner wall of the drive sleeve 2 is symmetrically fixed with limiting protrusions 201. The limiting protrusions 201 and the limiting grooves 104 slide in cooperation.

[0023] In this embodiment, the first connecting flange 102 can be connected to the power input end of the load device, and then the magnet base 1 can be used to drive the first drive shaft 101 to rotate. The first drive shaft 101 can drive the first connecting flange 102 to rotate, so that the first connecting flange 102 can drive the load device to operate. The limiting groove 104 and the limiting protrusion 201 are in sliding engagement, so that the second drive shaft 103 can only move inside the first connecting flange 102, avoiding the problem of relative rotation between the first connecting flange 102 and the second drive shaft 103.

[0024] Example 3 A mounting bracket 306 is fixedly connected to one side of the fixed base 303, and the other end of the mounting bracket 306 is fixedly connected to the power mechanism 9. Several telescopic connecting rods 309 are fixedly connected between the fixed base 303 and the adjusting base 307. The several telescopic connecting rods 309 are arranged in a row and evenly surround the adjusting screw 305. The telescopic adjusting rod includes the adjusting screw 305 and the threaded sleeve 308. One end of the adjusting screw 305 is fixedly connected to the output end of the adjusting motor 304, and the other end of the threaded sleeve 308 is fixedly connected to one side of the adjusting base 307. The threaded sleeve 308 is threadedly engaged with the adjusting screw 305.

[0025] In this embodiment, starting the adjusting motor 304 can drive the adjusting screw 305 to rotate. The adjusting screw 305 is threadedly engaged with the threaded sleeve 308, and the rotation of the adjusting screw 305 can drive the threaded sleeve 308 to move. The movement of the threaded sleeve 308 can drive the adjusting seat 307 to move, and then drive the second transmission shaft 103 to move through the second bearing 302. The telescopic connecting rod 309 is used to connect the fixed seat 303 and the adjusting seat 307, so that the fixed seat 303 and the adjusting seat 307 are on the same horizontal plane. The mounting bracket 306 is fixedly connected to the power mechanism 9, restricting the entire adjusting mechanism from rotating together.

[0026] The working principle and usage process of this invention are as follows: During the initial startup of the load equipment, if the load is too high and exceeds the normal torque transmission between the magnet seats 1, the starting adjustment motor 304 can drive the adjustment screw 305 to rotate. The adjustment screw 305 is threadedly engaged with the threaded sleeve 308, and the rotation of the adjustment screw 305 can drive the threaded sleeve 308 to move. The movement of the threaded sleeve 308 can drive the adjustment seat 307 to move, which in turn drives the second transmission shaft 103 to move through the second bearing 302. The second transmission shaft 103 drives the magnet seat 1 to move closer to the other magnet seat 1, reducing the distance between the two magnet seats 1 and increasing the torque transmission of the coupling. After the load equipment has started normally, the adjustment motor 304 needs to be controlled to drive the second transmission shaft 103 to reset, so that the air gap between the magnet seats 1 returns to the optimal state.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
