Description

Technical Field

[0001] This utility model relates to a brake, and more particularly to an electromagnetic brake. Background Technology

[0002] An electromagnetic brake is a connector that transmits torque from the active side to the passive side. It can be freely engaged, disengaged, or used for braking as needed. It features a compact structure, simple operation, sensitive response, long lifespan, reliable use, and ease of remote control. It is widely used in machinery in metallurgy, construction, chemical, food, machine tools, printing, and packaging industries, as well as in applications requiring braking during power outages. When energized, the winding generates a magnetic field that attracts the armature back, while simultaneously compressing the spring fixed within the iron core.

[0003] In existing electromagnetic brakes, the elastic disc rings are typically designed with a flat shape, resulting in a small gap between the brake disc and the rotating base. During braking, the large amount of heat generated by friction on the brake disc is difficult to dissipate quickly and tends to accumulate inside the brake, causing overheating. This not only reduces the braking performance of the electromagnetic brake but may also accelerate component aging, shorten its service life, and affect the reliability and safety of the equipment. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology in that the heat generated during brake disc braking cannot be dissipated quickly, the purpose of this utility model is to provide an electromagnetic brake.

[0005] The technical solution of this utility model is as follows: An electromagnetic brake, comprising:

[0006] Fixed base;

[0007] Brake filler, the brake filler being disposed at the left end of the fixed base;

[0008] A rotating base is mounted on the left side of the fixed base;

[0009] A brake disc, wherein the brake disc is disposed on the rotating base and located between the rotating base and the fixed base;

[0010] The elastic disc is disposed on the rotating base and located between the rotating base and the brake disc. The elastic disc is a circular disc composed of multiple sector plates, with adjacent sector plates staggered from each other.

[0011] Screws are used to thread the rotating base, the brake disc, and the elastic disc together.

[0012] Preferably, the brake disc is provided with heat dissipation holes 4a at intervals.

[0013] Preferably, the brake disc is provided with anti-crack grooves 4b at intervals.

[0014] Preferably, the brake disc is provided with positioning holes 4c spaced circumferentially, and the screw is located in the positioning holes 4c.

[0015] As a preferred option, it also includes:

[0016] An elastic washer is located inside the positioning hole 4c, and the screw passes through the elastic washer to thread the elastic disc together with the rotating base.

[0017] Preferably, the brake disc is provided with threaded holes spaced circumferentially, and the threaded holes are adapted to the screws.

[0018] Preferably, the brake filler is provided with heat dissipation holes 1a at intervals and anti-crack grooves 1b at intervals.

[0019] Preferably, the elastic disc has positioning holes 2c spaced apart, through which the screw passes.

[0020] Preferably, the rotating base is provided with positioning holes 6a spaced circumferentially. The screw located in the positioning hole 6a passes through the positioning hole 2c and is threadedly connected to the threaded hole, thereby threading the elastic washer together with the brake disc.

[0021] The beneficial effects are: 1. This utility model, through the staggered design of the fan-shaped plates of the elastic disc, increases the gap between the brake disc and the rotating base, thus improving the heat dissipation performance of the brake. The heat dissipation holes spaced evenly on both the brake disc and the fixed base significantly improve the heat dissipation efficiency of the brake, allowing the heat generated during braking to dissipate quickly.

Detailed Implementation

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] An electromagnetic brake, such as Figures 1-5 As shown, it includes: a fixed base 1; a brake filler 103; the brake filler 103 is disposed at the left end of the fixed base 1, and the brake filler 103 is provided with heat dissipation holes 1a101 spaced apart, and anti-crack grooves 1b102 spaced apart; a rotating base 6, which is installed on the left side of the fixed base 1; and a brake disc 4, which is disposed on the rotating base 6. When the brake disc 4 is in the braking process, the right side of the brake disc 4 will contact the left end of the brake filler 103, and the brake disc 4 will rub against the brake filler 103. To achieve the braking effect, it is located between the rotating base 6 and the fixed base 1; the elastic disc 5 is disposed on the rotating base 6, located between the rotating base 6 and the brake disc 4. The elastic disc 5 is a circular disc composed of multiple sector plates. Adjacent sector plates are staggered, and the staggered design of the sector plates increases the gap between the brake disc 4 and the rotating base 6, which is beneficial to the heat dissipation effect and increases the service life of this brake; the screw 2 is used to thread the rotating base 6, the brake disc 4 and the elastic disc 5 together.

[0030] like Figure 5As shown, the brake disc 4 is provided with heat dissipation holes 4a at intervals. The presence of heat dissipation holes 1a101 and 4a reduces the contact area between the brake disc 4 and the brake filler 103. The reduced contact area helps to reduce the heat generated by the brake disc 4 during braking and increases the contact area between the brake disc 4 and the air, thus accelerating the heat dissipation of the brake disc 4. The brake disc 4 is provided with anti-crack grooves 4b402 at intervals. When the brake disc 4 generates a large amount of heat during braking, the presence of anti-crack grooves 1b102 and 4b402 provides space for deformation of the brake disc 4 and the brake filler 103, making them less prone to deformation and cracking. The brake disc 4 is provided with positioning holes 4c403 at intervals in the circumferential direction. The screw 2 is located in the positioning hole 4c403. The brake disc 4 is provided with threaded holes 201 at intervals in the circumferential direction. The threaded holes 201 are adapted to the screw 2.

[0031] like Figure 2 As shown, it also includes: an elastic washer 3, which is located in the positioning hole 4c403. The screw 2 passes through the elastic washer 3 to thread the elastic disc 5 to the rotating base 6. The elastic washer 3 can prevent the screw 2 from damaging the elastic disc 5.

[0032] like Figure 4 As shown, the elastic disc 5 has positioning holes 2c202 spaced apart. The positioning holes 2c202 allow the screw 2 to pass through. The positioning holes 2c202 can help the screw 2 to quickly connect the elastic disc 5, the rotating base 6 and the brake disc 4 together.

[0033] like Figure 1 and Figure 2 As shown, the rotating base 6 is provided with positioning holes 6a601 spaced around the circumference. The presence of the positioning holes 6a601 is beneficial to the use of the screw 2. The screw 2 located in the positioning hole 6a601 passes through the positioning hole 2c202 and is threadedly connected to the threaded hole 201, thereby threading the elastic washer 3 and the brake disc 4 together.

[0034] To assemble this brake, the elastic disc 5 is fitted onto the rotating base 6, and then the brake disc 4 is placed on top of the elastic disc 5. The elastic disc 5 and the brake disc 4 are rotated so that one of the positioning holes 2c202 on the elastic disc 5 is aligned with one of the positioning holes 6a601, and the threaded hole 201 on the brake disc 4 is aligned with the positioning hole 2c202. The screw 2 is inserted from the bottom of the rotating base 6 into the positioning hole 6a601, and the screw 2 is rotated to thread the elastic disc 5 and the brake disc 4 together. Then, the elastic washer 3 is placed into the positioning hole 4c403 of the brake disc 4, and the screw 2 is inserted into the positioning hole 4c403. The screw 2 is rotated to thread the elastic disc 5 and the rotating base 6 together. Finally, the rotating base 6 and the fixed base 1 are assembled together, thus completing the assembly of the brake.
