Description

Technical Field

[0001] This utility model relates to the field of brake technology, and in particular to an adjustable torque-increasing brake. Background Technology

[0002] Existing spring-loaded electromagnetic brakes apply pressure to the armature via a spring, which acts on the rotating friction flange to generate braking torque. By energizing the electromagnetic coil, electromagnetic force is generated to pull the armature back, thereby releasing the brake. Typically, the brake has only one rotating friction flange, and with only two friction surfaces, the braking effect is poor.

[0003] To address the aforementioned issues, we propose an adjustable torque-enhancing brake. This brake uses an adjustable screw to ensure the clearance. When the clearance becomes too large, it can be reduced by adjusting the screw, thus increasing the brake's service life. Furthermore, the adjustable torque-enhancing brake typically employs two rotating friction flanges, resulting in four friction surfaces, thereby increasing the torque. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable torque-increasing brake, solving the technical problem that existing spring-pressurized electromagnetic brakes generate braking torque by applying pressure to the armature with a spring, which then acts on the rotating friction flange; by energizing the electromagnetic coil, electromagnetic force is generated to pull the armature back, thereby releasing the brake. Typically, the brake only has one rotating friction flange, resulting in only two friction surfaces and low braking effect.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adjustable torque-increasing brake includes an internal drive unit. A coil seat is fixedly mounted on the outside of the internal drive unit. A connecting shaft is driven to the output end of the internal drive unit. Electromagnetic coils are installed both above and below the inside of the coil seat. A friction rotating flange is fixedly sleeved on the outside of the connecting shaft. Friction plates are provided on one side of the friction rotating flange. A connecting flange is fixedly connected to the side of the friction plates away from the friction rotating flange. An armature plate is provided on one side of the coil seat. The armature plate is rotatably connected to the outside of the connecting shaft. The connecting flange is rotatably connected to the outside of the connecting shaft. A restoring spring is fixedly connected between the middle of the armature plate and the inner wall of the coil seat.

[0009] The technical effect of adopting the above-mentioned further solution is that the internal drive device can provide power to the connecting shaft, and the connecting shaft can drive the friction rotating flange to rotate. During braking: (e.g.) Figure 1 As shown: When the electromagnetic coil is de-energized, the magnetic field disappears, and the restoring spring returns to its original position. Under the action of the restoring force, it drives the fast armature plate to move towards the coil seat. Simultaneously, the adjusting bolts move the two connecting flanges closer to the friction rotating flange until the friction plates are in close contact with all four sides of the friction rotating flange. This provides a braking effect on the connecting shaft. In the non-braking state: When the electromagnetic coil is energized: as shown... Figure 2 As shown, the electromagnetic coil generates an electric field after being energized. Under the action of the electric field force, it can push the armature plate to move away from the electromagnetic coil, and drive the two connecting flanges and friction plates away from the friction rotating flange, so that the connecting shaft can operate normally.

[0010] Preferably, a guide plate is fixedly connected to the upper end of the armature plate, and a limiting groove corresponding to the guide plate is opened inside the coil seat.

[0011] The technical effect of adopting the above-mentioned further solution is that the guide plate and the limiting slot can make the armature plate more stable when moving.

[0012] Preferably, the connecting flanges are threaded together with adjusting bolts, one end of which is fitted with a connecting bearing, and the adjusting bolt is rotatably engaged with the armature plate through the connecting bearing.

[0013] The technical effect of adopting the above-mentioned further solution is that the friction plate will become thinner due to long-term wear. Once the wear is severe, it will reduce the braking effect on the connecting shaft. At this time, it is only necessary to rotate the adjusting bolt. Under the restriction of the connecting shaft, the connecting flange will slowly move closer to the friction rotating flange, thereby reducing the distance between the friction plate and the friction rotating flange, thereby improving the braking effect on the connecting shaft.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by setting up an armature plate, a restoring spring, a guide plate, a limiting groove, a connecting flange, a friction plate, and a friction rotating flange, can make the friction plate and the friction rotating flange fit together under the magnetic force of the electromagnetic coil, thereby achieving effective braking of the connecting shaft.

[0017] 2. This utility model, by setting an adjusting bolt, a connecting bearing, and a connecting flange, allows the connecting flange to slowly move closer to the friction rotating flange under the constraint of the connecting shaft when the adjusting bolt is rotated. This reduces the distance between the friction plate and the friction rotating flange, thereby improving the braking effect on the connecting shaft and extending the service life of the brake.

[0024] This application provides an adjustable torque-enhancing brake. By incorporating an armature plate, a restoring spring, a guide plate, a limit slot, a connecting flange, a friction pad, and a friction rotating flange, the friction pad can be brought into contact with the friction rotating flange under the magnetic force of the electromagnetic coil. This achieves effective braking of the connecting shaft. By incorporating an adjusting bolt, a connecting bearing, and a connecting flange, rotating the adjusting bolt causes the connecting flange to slowly move closer to the friction rotating flange under the constraint of the connecting shaft. This reduces the distance between the friction pad and the friction rotating flange, thereby improving the braking effect on the connecting shaft and extending the service life of the brake.

[0025] Example 1

[0026] The technical solution in this application embodiment effectively solves the technical problem of existing spring-loaded electromagnetic brakes, which use a spring to apply pressure to the armature, acting on a rotating friction flange to generate braking torque; and then generate electromagnetic force by energizing the electromagnetic coil to pull the armature back, thereby releasing the brake. Typically, these brakes only have one rotating friction flange, resulting in only two friction surfaces and low braking efficiency. The overall approach is as follows:

[0027] like Figures 1 to 4To address the problems existing in the prior art, this utility model provides an adjustable torque-increasing brake, including an internal drive device 1, a coil seat 2 fixedly mounted on the outside of the internal drive device 1, a connecting shaft 101 drivingly connected to the output end of the internal drive device 1, electromagnetic coils 3 installed on the upper and lower parts of the coil seat 2, a friction rotating flange 7 fixedly sleeved on the outside of the connecting shaft 101, friction plates 61 provided on one side of the friction rotating flange 7, a connecting flange 6 fixedly connected to the side of the friction plates 61 away from the friction rotating flange 7, an armature plate 4 provided on one side of the coil seat 2, the armature plate 4 rotatably connected to the outside of the connecting shaft 101, the connecting flange 6 rotatably connected to the outside of the connecting shaft 101, a restoring spring 41 fixedly connected between the middle part of the armature plate 4 and the inner wall of the coil seat 2, and a restoring spring 41 fixedly connected between the middle part of the armature plate 4 and the inner wall of the coil seat 2.

[0028] By adopting the above technical solution, during use, the internal drive device 1 can provide power to the connecting shaft 101, and the connecting shaft 101 can drive the friction rotating flange 7 to rotate. During braking: (e.g.) Figure 1 As shown: After the electromagnetic coil 3 is de-energized, the magnetic field disappears, and the restoring spring 41 returns to its original state. Under the action of the restoring force, it drives the fast armature plate 4 to move towards the coil seat 2. At the same time, it moves the two connecting flanges 6 towards the friction rotating flange 7 through the adjusting bolt 5, until the friction plate 61 is in close contact with the four sides of the friction rotating flange 7. This can brake the connecting shaft 101. In the non-braking state: When the electromagnetic coil 3 is energized: as shown Figure 2 As shown, the electromagnetic coil 3 generates an electric field after being energized. Under the action of the electric field force, it can push the armature plate 4 to move away from the electromagnetic coil 3, and drive the two connecting flanges 6 and friction plates 61 away from the friction rotating flange 7. In this way, the connecting shaft 101 can operate normally. The guide plate 42 and the limiting slot 43 can make the armature plate 4 more stable when moving.

[0029] Example 2

[0030] like Figures 1 to 4 An adjusting bolt 5 is threaded between the connecting flanges 6. A connecting bearing 51 is installed at one end of the adjusting bolt 5. The adjusting bolt 5 is rotated and engaged with the armature plate 4 through the connecting bearing 51.

[0031] By adopting the above technical solution, the friction plate 61 will become thinner due to long-term wear. Once the wear is severe, it will reduce the braking effect on the connecting shaft 101. At this time, it is only necessary to rotate the adjusting bolt 5. Under the restriction of the connecting shaft 101, the connecting flange 6 will slowly move closer to the friction rotating flange 7, thereby reducing the distance between the friction plate 61 and the friction rotating flange 7, thereby improving the braking effect on the connecting shaft 101.

[0032] Working principle: During use, the internal drive device 1 provides power to the connecting shaft 101, which in turn drives the friction rotating flange 7 to rotate. During braking: (e.g.) Figure 1 As shown: After the electromagnetic coil 3 is de-energized, the magnetic field disappears, and the restoring spring 41 returns to its original state. Under the action of the restoring force, it drives the fast armature plate 4 to move towards the coil seat 2. At the same time, it moves the two connecting flanges 6 towards the friction rotating flange 7 through the adjusting bolt 5, until the friction plate 61 is in close contact with the four sides of the friction rotating flange 7. This can brake the connecting shaft 101. In the non-braking state: When the electromagnetic coil 3 is energized: as shown Figure 2 As shown, the energized electromagnetic coil 3 generates an electric field. Under the action of the electric field force, it can push the armature plate 4 to move away from the electromagnetic coil 3, and drive the two connecting flanges 6 and the friction plate 61 away from the friction rotating flange 7. In this way, the connecting shaft 101 can operate normally. The guide plate 42 and the limiting groove 43 can make the armature plate 4 more stable when moving. The friction plate 61 will become thinner with long-term wear. Once the wear is serious, it will reduce the braking effect on the connecting shaft 101. At this time, it is only necessary to rotate the adjusting bolt 5. The connecting flange 6 will slowly move closer to the friction rotating flange 7 under the restriction of the connecting shaft 101, thereby reducing the distance between the friction plate 61 and the friction rotating flange 7, thereby improving the braking effect on the connecting shaft 101.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
