Description

Technical Field

[0001] This utility model relates to the field of magnetic powder brake technology, specifically a hollow magnetic powder brake. Background Technology

[0002] Magnetic powder brakes are automatic control components based on electromagnetic principles and the torque transmission of magnetic powder. They achieve stepless speed regulation and stable braking by adjusting the excitation current. They have advantages such as high torque control accuracy, strong constant torque characteristics, fast response speed, and good durability. They are widely used in winding tension control, overload protection of transmission machinery, and buffer start-up in industries such as papermaking, printing, and textiles. When selecting a model, it is necessary to consider torque, speed, heat dissipation, and installation requirements to ensure that it matches the working conditions.

[0003] According to the magnetic powder brake published on the China Patent Network with publication number CN201307821Y, it includes an outer cover, a coil, a non-magnetic rotating shaft, a plurality of magnetic attraction components, and at least one isolation component. The key feature is that the coil, magnetic attraction components, and isolation component are located inside the outer cover, and the coil surrounds the periphery of the magnetic attraction components and the isolation component. The magnetic attraction component includes an outer copper ring and a rotor. The outer copper ring surrounds the outer ring of the rotor and is electrically connected to the coil. The isolation component is located between the magnetic attraction components and includes a partition plate and an inner copper ring. The partition plate surrounds the outer copper ring. Magnetic powder is distributed between the rotor and the partition plate on the outer ring of the inner copper ring. The non-magnetic shaft passes through the center of the outer cover and through the inner copper ring and is fixed to the rotor. In this way, when the coil conducts electricity, the magnetic powder is attracted to the rotor surface in a bundle shape under the influence of the current. The magnetic powder generates magnetism under the influence of the current, thereby braking the rotor torque. The rotor can synchronously brake the rotation of the non-magnetic shaft. However, the heat dissipation effect of this magnetic powder brake is poor. After braking, the electromagnetic coil will generate heat, which is difficult to dissipate through the housing in time. The excessively high temperature will affect the braking effect of the brake and accelerate the aging of the magnetic powder.

[0004] Therefore, the magnetic powder brake needs to be redesigned and modified to effectively prevent its poor heat dissipation. Utility Model Content

The circular sleeve 304 is located on the left side of the baffle 302.

[0027] As a technical optimization of this utility model, by setting the fixing component 3, the fixing cover 203 can be fixedly supported, thereby improving the ease of assembly and disassembly of the fixing cover 203.

[0028] refer to Figure 5 A magnet plate 4 is fixedly connected to the left side of the fixed cover 203, and the circular sleeve 304 is attracted to the magnet plate 4.

[0029] As a technical optimization of this utility model, by setting the magnet plate 4, the circular sleeve 304 can be limited, preventing the circular sleeve 304 from rotating at will, thus improving the stability of the circular sleeve 304.

[0030] refer to Figure 3 A dustproof net 5 is provided on the right side of the fixed cover 203, and a magnetic ring 6 is fixedly connected to the left side of the dustproof net 5. The left side of the magnetic ring 6 is attracted to the right side of the fixed cover 203.

[0040] The working principle and usage process of this utility model are as follows: When the brake body 1 is put into operation, its transmission shaft 201 will synchronously drive the fan 202 to rotate. With the suction effect of the fan 202, external air is introduced into the inner cavity of the fixed cover 203. During this process, the dustproof net 5 can effectively intercept dust and foreign objects in the air, preventing them from entering the fixed cover 203 and interfering with the operation of the brake. The filtered air will flow through the ventilation frame 204 and the heat-conducting fins 206, and carry away the heat generated by the brake body 1 through heat exchange, forming an efficient heat dissipation cycle. When it is necessary to maintain and disassemble the heat dissipation component 2, simply rotate the anti-slip block 7 to separate the round sleeve 304 from the magnetic plate 4 and remove it. Then rotate the fixed cover 203 to make its short rod 303 disengage from the baffle 302 limit. Finally, pull it to the right to completely disassemble the entire fixed cover 203 component. The fixed cover 203 and the fan 202 can be installed by reversing the above steps. The operation process is simple and the structure is stable.

[0041] In summary, this hollow magnetic powder brake utilizes a heat dissipation component to effectively cool the brake body. After braking, the electromagnetic coil generates heat, which can be promptly dissipated through the housing, preventing excessively high temperatures from affecting the braking effect and preventing high temperatures from accelerating the aging of the magnetic powder, thus solving the problem of poor heat dissipation.
