Description

Technical Field

[0001] This utility model relates to the field of braking technology, specifically to a dual-redundant energized brake. Background Technology

[0002] A brake is a device that slows down, stops, or keeps a moving part (or machine) at a stop. It is a mechanical part that stops or slows down moving parts in machinery. Commonly known as a brake or decelerator.

[0003] A brake mainly consists of a frame, braking components, and an operating device. In existing brakes, an electromagnet is energized, driving an armature to move and thus press the brake pads tightly against the rotor, achieving braking. When braking is no longer needed, the brake pads return to their original position via the restoring force of a spring. However, a drawback of existing technology is that over time, the spring's elastic coefficient gradually decreases, eventually rendering it ineffective.

[0004] Therefore, it is necessary to propose a dual-redundant energized brake that adjusts the deformation of the spring as the spring elastic coefficient gradually decreases, thus ensuring the spring force. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and propose a dual-redundant energized brake that can adjust the distance between the rotor and the brake pads to adapt to different scenario requirements.

[0006] The purpose of this utility model is achieved through the following technical solution: a dual-redundant energized brake, comprising a stator and a rotor rotatably mounted on the stator, wherein an electromagnet, a permanent magnet, and an armature are sequentially arranged on the side of the stator near the rotor, a brake pad for braking the rotor is arranged between the stator and the rotor, and a spring is arranged between the rotor and the brake pad. The rotor has multiple grooves evenly distributed in a ring around its center on the side away from the stator, and an adjusting bolt is threaded through the grooves. A protrusion is provided at the end of the adjusting bolt, and the spring and brake pad are slidably sleeved on the adjusting bolt.

[0007] The stator is provided with multiple positioning columns that are evenly distributed in a ring around the center of the rotor on the side away from the rotor.

[0008] The stator has a mounting through hole at its center, and the rotor has a mounting post that is rotatably mounted on the mounting through hole.

[0009] A bearing is provided on the mounting through hole, and the bearing is sleeved on the mounting column.

[0010] The stator has an annular groove centered on the rotor side. The electromagnet, permanent magnet, and armature are slidably disposed in the annular groove, and the armature is connected to the brake pad.

[0011] The rotor has a slot for placing springs on the side closest to the robot.

[0012] A pressure plate is slidably disposed in the placement groove, and the pressure plate is slidably sleeved on the pressure plate.

[0013] The pressure plate is provided with sliding columns and telescopic rods at both ends on the side away from the spring plate, which slide through the inside of the rotor. The telescopic rod is provided with an inner tangent end that slides through the rotor.

[0014] The telescopic rod includes a mother rod disposed inside the rotor and a daughter rod that slides through the rotor. The daughter rod is threaded and rotatably connected to the mother rod. A first gear is fixedly sleeved on the mother rod. A second gear meshes with one side of the first gear. A turntable is rotatably disposed on the side wall of the rotor. The turntable is connected to the second gear through a connecting rod.

[0015] The stator has multiple positioning and mounting through holes on its periphery.

[0016] The beneficial effects of this utility model are: by setting an adjusting bolt, the size of the spring can be adjusted, thereby adjusting the degree of deformation of the spring, and ensuring the elasticity of the spring even as the elastic coefficient of the spring gradually decreases.

[0023] 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.

[0024] Example 1

[0025] A dual-redundant energized brake, see [link / reference] Figures 1-3 The system includes a stator 1 and a rotor 2. A mounting through-hole 12 is provided at the center of the stator 1. A mounting post 13 is provided at the center of the rotor 2 near the stator 1. The mounting post 13 is rotatably mounted at the mounting through-hole 12. A bearing 14 is provided at the mounting through-hole 12. The bearing 14 is sleeved on the mounting post 13.

[0026] Four positioning posts 11, evenly distributed in a ring around the center of the post, are provided on the side of the stator 1 away from the rotor 2. Positioning and mounting through holes 26 are provided at the top, bottom, left, and right ends of the stator 1 away from the rotor 2. Fixing bolts can be passed through the positioning and mounting through holes 23 to fix the stator 1 to the fixed surface.

[0027] Multiple brake pads 6 are disposed between the stator 1 and the rotor 2. The brake pads 6 are friction pads. The multiple brake pads 6 are evenly distributed in a ring around the mounting post 13. An annular groove 15, centered on the mounting post 13, is formed on the side of the stator 1 closest to the rotor 2. An electromagnet 3, a permanent magnet 4, and an armature 5 are sequentially disposed within the annular groove 15, moving from the direction furthest from the rotor 2 towards the direction closest to the rotor 2. The permanent magnet 4 and the armature 5 are connected and slidably connected to the inner wall of the annular groove 15. The electromagnet 3 is fixedly disposed within the annular groove 15. The armature 5 is fixedly connected to the brake pads 6.

[0028] The rotor 2 has multiple grooves 8 corresponding to the positions of the brake pads 6. On the side of the rotor 2 near the brake pads 6, multiple placement slots 16 corresponding to the positions of the brake pads 6 are also provided. A spring 7 is placed within each placement slot 16. The spring 7 abuts against the placement slot 16 and the brake pad 6 on both sides. An adjusting bolt 9 is threaded through the groove 8. A protrusion 10 is provided at the end of the adjusting bolt 9. The spring 7 and the brake pad 6 are slidably fitted onto the adjusting bolt 9. The spring 7 abuts against the inner wall of the placement slot 16 and the brake pad 6 on both sides.

[0029] When the elastic coefficient of the reed 7 decreases, the adjusting bolt 9 is rotated, thereby changing the degree of deformation of the reed 7 and thus changing the restoring force of the reed 7.

[0030] Example 2

[0031] If the elastic coefficient of the spring 7 decreases to a certain extent, rotating the adjusting bolt 9 will change the deformation of the spring 7, but when the size of the spring 7 after restoration is smaller than the size of the placement groove 16, the spring 7 will still be unable to push the brake pad 6 to separate from the rotor 2. Therefore, Embodiment 2 is proposed to solve this problem.

[0032] refer to Figure 4 and Figure 5 A pressure plate 17 is installed in the placement groove 6. The pressure plate 17 is slidably sleeved on the adjusting bolt 9. The pressure plate 17 abuts against the side of the spring 7 away from the brake pad 6. A sliding column 18 and a telescopic rod 19 are respectively installed at both ends of the pressure plate 17 away from the spring. The sliding column 18 is slidably inserted into the rotor 2. The telescopic rod 19 includes a female rod 24 and a female rod 25 threadedly connected. The female rod 24 is rotatably installed inside the rotor 2, and the female rod 25 is slidably inserted into the rotor 2 and connected to the pressure plate 17. A first gear 20 is fixedly sleeved on the female rod 24. A second gear 21 meshes with one side of the first gear 20. A turntable 22 is rotatably installed on the side wall of the rotor 2. The turntable 22 is connected to the second gear 21 via a connecting rod 23.

[0033] When adjusting the spring 7 by rotating the adjusting bolt 9 fails to achieve the desired effect, the turntable 22 can be rotated to drive the pressure plate 17 to move, thus changing the degree of deformation of the spring 7. This allows the brake pad 6 to separate from the rotor 2 when the spring 7 returns to its original position.

It should be understood that this utility model is not limited to the form 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 description or the technology or knowledge in related fields.
