Description

Technical Field

[0001] This utility model relates to the field of brake technology, specifically a high-torque 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 has advantages such as compact structure, simple operation, sensitive response, long service life, reliable use, and easy remote control. High-torque electromagnetic brakes mainly achieve greater braking torque by optimizing the magnetic circuit design, increasing the number of windings of the electromagnetic coil, or using high magnetic permeability materials to generate a stronger magnetic field during operation. However, most of the surface of high-torque electromagnetic brakes does not have noise reduction structures, which may lead to significant electromagnetic noise, mechanical noise, and aerodynamic noise during operation. Noise may cause problems such as loose fasteners and fatigue damage to components, reducing the service life of high-torque electromagnetic brakes. Utility Model Content

[0003] The purpose of this invention is to provide a high-torque electromagnetic brake to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-torque electromagnetic brake, comprising an electromagnetic brake body, a brake pad at the left end of the electromagnetic brake body, a bolt inside the brake pad, a sound-absorbing sleeve outer sleeve of the electromagnetic brake body, a cross block fixedly connected inside the sound-absorbing sleeve, a cross groove outside the electromagnetic brake body, a snap-fit ​​structure inside the electromagnetic brake body, the snap-fit ​​structure snapping with the cross block, an auxiliary structure on one side of the sound-absorbing sleeve, a sealing ring rotatably connected to the auxiliary structure, the snap-fit ​​structure comprising a collar and an arc-shaped plate, and a bolt inside the collar.

[0005] As a further preferred embodiment of this technical solution, the sound-absorbing sleeve is fitted over the brake pad, the brake pad is connected to the electromagnetic brake body by bolt two, and the sealing ring overlaps the front side of the brake pad.

[0006] As a further preferred embodiment of this technical solution, the cross block is engaged within the electromagnetic brake body, the collar is rotatably connected to the right end of the electromagnetic brake body, and the arc-shaped plate is fixedly connected to the outside of the collar.

[0007] As a further preferred embodiment of this technical solution, the collar is connected to the electromagnetic brake body by a bolt, the arc-shaped plate is snapped into the cross block, and the arc-shaped plate is rotatably connected to the electromagnetic brake body.

[0008] As a further preferred embodiment of this technical solution, the auxiliary structure includes a fixed column and a fixed plate. The fixed column is fixedly connected to one side of the sound-absorbing sleeve, the sealing ring is rotatably connected to the outside of the fixed column, and the fixed plate is fixedly connected to one end of the fixed column.

[0009] As a further preferred embodiment of this technical solution, a limiting disc is slidably connected to the outside of the fixed column, the limiting disc is engaged within the sealing ring, and a movable rod is fixedly connected to one side of the limiting disc, the movable rod being slidably connected within the fixed disc.

[0010] As a further preferred embodiment of this technical solution, the moving rod is fitted with a spring, one end of the moving rod is fixedly connected to a connecting plate, and the limiting plate is connected to the fixed plate via a spring.

[0011] This utility model provides a high-torque electromagnetic brake, which has the following advantages:

[0012] (1) This utility model sets up a sound-absorbing sleeve, a snap-fit ​​structure, a cross groove and a cross block. The sound-absorbing sleeve slides in the cross groove through the cross block. When the sound-absorbing sleeve is fully attached to the electromagnetic brake body, the ring is driven to rotate in the electromagnetic brake body by the bolt. When the ring rotates, the arc plate on the surface will snap into the cross block. Then the ring is threaded to the electromagnetic brake body by the bolt. The high-torque electromagnetic brake enables the sound-absorbing sleeve and the electromagnetic brake body to be quickly assembled through the snap-fit ​​structure, the cross groove and the cross block. It is convenient to replace or repair the sound-absorbing sleeve in the future, and avoids the phenomenon of noise transmission. It also avoids problems such as loosening of fasteners caused by the transmitted noise, thus ensuring the service life of the high-torque electromagnetic brake.

[0013] (2) By setting an auxiliary structure and a sealing ring, the present invention applies a pulling force to the limiting plate through the connecting plate and the moving rod. When the limiting plate slides on the surface of the fixed column, it will drive the spring to deform. When the limiting plate is separated from the sealing ring, the sealing ring will flip around the fixed column. The flipped sealing ring will overlap the front of the bolt two. After the limiting plate is released, it will be reset by the spring. The reset limiting plate will be locked into the sealing ring, thereby locking the position of the sealing ring. This facilitates the adjustment of the angle of the sealing ring and prevents the sealing ring from colliding with the electromagnetic brake body when the sound-absorbing sleeve is sleeved with it.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown in this embodiment, a high-torque electromagnetic brake includes an electromagnetic brake body 1. A brake pad 5 is provided at the left end of the electromagnetic brake body 1. A bolt 7 is provided inside the brake pad 5. A sound-absorbing sleeve 2 is fitted over the electromagnetic brake body 1. A cross block 9 is fixedly connected inside the sound-absorbing sleeve 2. A cross groove 8 is provided on the outside of the electromagnetic brake body 1. A snap-fit ​​structure 3 is provided inside the electromagnetic brake body 1. The snap-fit ​​structure 3 snaps with the cross block 9. An auxiliary structure 4 is provided on one side of the sound-absorbing sleeve 2. A sealing ring 6 is rotatably connected to the outside of the auxiliary structure 4. The snap-fit ​​structure 3 includes a collar 301 and an arc plate 303. A bolt 302 is provided inside the collar 301.

[0022] like Figure 1-5 As shown, the sound-absorbing sleeve 2 is sleeved on the outside of the brake pad 5. The brake pad 5 is connected to the electromagnetic brake body 1 by bolt 2 7. The sealing ring 6 overlaps on the front of the brake pad 5. The cross block 9 is snapped into the electromagnetic brake body 1. The collar 301 is rotatably connected to the right end of the electromagnetic brake body 1. The arc plate 303 is fixedly connected to the outside of the collar 301. The collar 301 is connected to the electromagnetic brake body 1 by bolt 1 302. The arc plate 303 is snapped into the cross block 9. The arc plate 303 is rotatably connected into the electromagnetic brake body 1.

[0023] By setting the cross groove 8 and the cross block 9, when the sound-absorbing sleeve 2 is installed with the electromagnetic brake body 1, the sound-absorbing sleeve 2 will slide in the cross groove 8 through the cross block 9, so that the cross groove 8 and the cross block 9 can position the sound-absorbing sleeve 2 and prevent the sound-absorbing sleeve 2 from shifting from the position of the electromagnetic brake body 1 when it is fixed.

[0024] like Figure 2-4 As shown, the auxiliary structure 4 includes a fixed column 401 and a fixed plate 402. The fixed column 401 is fixedly connected to one side of the sound-absorbing sleeve 2. The sealing ring 6 is rotatably connected to the outside of the fixed column 401. The fixed plate 402 is fixedly connected to one end of the fixed column 401. A limiting plate 403 is slidably connected to the outside of the fixed column 401. The limiting plate 403 is snapped into the sealing ring 6. A moving rod 404 is fixedly connected to one side of the limiting plate 403. The moving rod 404 is slidably connected to the fixed plate 402. A spring 405 is sleeved on the moving rod 404. A connecting plate 406 is fixedly connected to one end of the moving rod 404. The limiting plate 403 is connected to the fixed plate 402 through the spring 405.

[0025] By setting the sealing ring 6, when the limiting plate 403 is separated from the sealing ring 6, the sealing ring 6 will flip around the fixing post 401 as the center. After flipping, the sealing ring 6 will overlap the front of the bolt 7, so that the sealing ring 6 can protect the bolt 7 inside the brake pad 5 and prevent the bolt 7 from being exposed to the outside for a long time and causing wear.

[0026] This utility model provides a high-torque electromagnetic brake, the specific working principle of which is as follows:

[0027] When the high-torque electromagnetic brake is in use, the brake pad 5 is overlapped with the electromagnetic brake body 1 and then fixed to it by bolt 7. Then, the sound-absorbing sleeve 2 slides in the cross groove 8 through the cross block 9. When the sound-absorbing sleeve 2 is fully attached to the electromagnetic brake body 1, the ring 301 is driven to rotate in the electromagnetic brake body 1 by bolt 302. When the ring 301 rotates, the arc plate 303 on its surface will be engaged in the cross block 9. Then the ring 301 is threadedly connected to the electromagnetic brake body 1 by bolt 302.

[0028] Subsequently, a pulling force is applied to the limiting plate 403 through the connecting plate 406 and the moving rod 404. When the limiting plate 403 slides on the surface of the fixed column 401, it will cause the spring 405 to deform. When the limiting plate 403 is separated from the sealing ring 6, the sealing ring 6 will flip around the fixed column 401. After flipping, the sealing ring 6 will overlap the front of the bolt 2 7. After the limiting plate 403 is released, it will be reset by the spring 405. After the reset, the limiting plate 403 will be locked into the sealing ring 6.

[0029] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
