Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic brake technology, and in particular relates to a high heat dissipation electromagnetic brake with a segmented replaceable slot disc. Background Technology

[0002] The yoke is one of the core components of an electromagnetic brake, primarily responsible for generating an electromagnetic field to achieve the braking function. The yoke is typically made of metal and contains an internal electromagnetic coil. When current flows through the coil, it generates a magnetic field that interacts with the armature or other components, thereby achieving braking or release.

[0003] Traditional magnetic yoke electromagnetic brakes typically use an integrated magnetic yoke. If a part of it is damaged, the entire yoke often needs to be replaced. If the coil or potting material has a problem after potting, the entire device must be scrapped, which increases maintenance costs and time.

[0004] Meanwhile, existing brakes typically use housings (such as rear covers) for natural heat dissipation. However, conventional housings have limited heat dissipation capabilities, making it difficult for heat to dissipate quickly. This can easily lead to brake overheating, resulting in performance degradation or even safety hazards.

[0005] Therefore, a new electromagnetic brake structure is needed that can be easily replaced and has improved heat dissipation. Utility Model Content

[0006] The purpose of this invention is to provide a high-heat-dissipation electromagnetic brake with a modular replaceable slot plate to solve the problems existing in the background art.

[0007] The objective of this utility model is achieved through the following technical solution: A high-heat-dissipation electromagnetic brake with a modular replaceable slotted disc includes a housing and a magnetic yoke assembly, a moving plate, and a rotor assembly located within the housing. The magnetic yoke assembly is a split structure, and the magnetic yoke assembly includes multiple fan-shaped magnetic yokes of the same specifications. Each magnetic yoke is equipped with a coil and a spring. The inner side of the housing is provided with heat dissipation fins.

[0008] Furthermore, the inner side of the magnetic yoke is provided with a slot, and the slots of the multiple magnetic yokes form a circular groove. A retaining ring is provided in the circular groove, and the multiple magnetic yokes are connected through the retaining ring.

[0009] Furthermore, the coil within each yoke is located in the middle of the corresponding yoke, and the two springs are located on either side of the corresponding coil, with the centers of the springs and the coils on the same pitch circle.

[0010] Furthermore, the magnetic yoke assembly, the moving plate, and the rotor assembly are arranged sequentially from the inside to the outside along the housing. A flange is provided at one end of the opening of the housing. The flange is located outside the rotor assembly, and the flange is connected to the magnetic yoke by bolts.

[0011] Furthermore, the bottom of the magnetic yoke is connected to the bottom of the housing by screws.

[0012] Furthermore, the housing and heat dissipation fins are made of aluminum, and the plurality of heat dissipation fins are arranged in a ring-shaped radial pattern.

[0013] Furthermore, the heat dissipation fins have an L-shaped structure, and the magnetic yoke is located on the heat dissipation fins.

[0014] The beneficial effects of this utility model are: 1) Modular maintenance of the yoke assembly is achieved through a segmented yoke design. When a segment fails, it can be replaced individually instead of the entire assembly, significantly reducing maintenance costs and downtime.

[0015] 2) The segmented structure also optimizes heat dissipation performance. A certain gap can be set between each segment to ensure air circulation, which can more effectively dissipate the heat generated during braking.

[0016] 3) Heat dissipation fins are installed on the inner wall of the housing to greatly improve heat dissipation efficiency and ensure that the brake can operate stably under continuous work or high load conditions, avoiding performance degradation or safety hazards due to overheating.

Detailed Implementation

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

[0019] See Figures 1-6 This utility model provides a technical solution: like Figure 1 and Figure 2 As shown, a high-heat-dissipation electromagnetic brake with a segmented replaceable slot plate includes a housing 1 and a magnetic yoke assembly 2, a moving plate 3, and a rotor assembly 4 located within the housing 1. The magnetic yoke assembly 2, the moving plate 3, and the rotor assembly 4 are arranged sequentially from the inside to the outside along the housing 1. At the same time, a flange 5 is provided at one end of the opening of the housing 1. The flange 5 is located outside the rotor assembly 4, and the flange 5 is connected to the magnetic yoke 21 by bolts.

[0020] The basic principle of the brake in this scheme is as follows: the magnetic yoke 21 plays the role of constructing a closed magnetic circuit with low magnetic resistance, and the coil 22 generates a magnetic field. When current passes through the coil 22, it generates magnetic flux. The magnetic yoke 21 generates an electromagnetic attraction force on the moving plate 3 and attracts it to the end face of the magnetic yoke 21. By continuously energizing the moving plate 3, the moving plate 3 is attracted and separated from the rotor assembly 4 after overcoming the elastic force of the spring 23, and the rotor assembly 4 continues to rotate. When the power is cut off, the moving plate 3 is released by the force of the spring 23, and the moving plate 3 is combined with the rotor assembly 4 to generate braking torque.

[0021] In this embodiment, as Figure 1 As shown, the magnetic yoke assembly 2 consists of three sets of identical sector-shaped magnetic yokes 21, with the bottom of the magnetic yokes 21 connected to the bottom of the housing 1 by screws. The magnetic yokes 21 are also connected to the flange 5 by bolts.

[0022] like Figure 3 As shown, each magnetic yoke 21 has a mounting slot for placing the coil 22 and spring 23, and also a screw hole for fixing it to the housing 1. Each magnetic yoke 21 and its corresponding coil 22 and spring 23 constitute a set of slots. Continuing as... Figure 1 As shown, the coil 22 in each of the magnetic yokes 21 is located in the middle of the corresponding magnetic yoke 21, and the two springs 23 are located on both sides of the corresponding coil 22. The centers of the springs 23 and the coils 22 are on the same pitch circle.

[0023] Furthermore, such as Figure 2 and Figure 4As shown, the inner side of the magnetic yoke 21 is provided with a slot 24. After multiple slots 24 form a circular groove, the retaining ring is placed in the slot 24. The slot 24 is provided with a slot for engaging the retaining ring. Multiple magnetic yokes 21 are connected by the retaining ring 6.

[0024] Since each yoke 21 has a corresponding coil 22, slot 24, and spring 23, the function of the yoke assembly 2 is achieved through the combination of multiple modular yokes 21. Each yoke 21 and its corresponding coil 22 and spring 23 are equivalent to a set of slots, and the modular design of the yoke assembly 2 allows for modular maintenance of the corresponding slots. When a segment fails, the slot of that segment can be replaced individually without replacing the entire assembly, significantly reducing maintenance costs and downtime. Furthermore, the modular structure optimizes heat dissipation; gaps can be established between the yoke segments to ensure airflow and more effectively dissipate heat generated during braking.

[0025] like Figure 5 As shown, heat dissipation fins 11 are provided on the inner side of the housing 1. In order to enhance the heat dissipation effect, the housing 1 and the heat dissipation fins 11 are made of aluminum, and the plurality of heat dissipation fins 11 are arranged in a ring-shaped radial pattern.

[0026] The ring-shaped heat dissipation fins 11 increase the heat dissipation area, allowing heat accumulated inside the brake to be transferred to the outside air more quickly. Simultaneously, they optimize the airflow path, guiding air to flow more efficiently and thus carrying away more heat.

[0027] like Figure 6 As shown, the heat dissipation fins 11 have an L-shaped structure, and the magnetic yoke 21 is located on the heat dissipation fins 11. The L-shaped heat dissipation fins 11 allow the sidewall of the magnetic yoke 21 to contact the bottom heat dissipation fins 11, achieving heat conduction. While relying on natural convection for heat dissipation, the heat dissipation fins 11 improve the heat dissipation effect, ensuring rapid heat dissipation and preventing the brake from overheating.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
