[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This direct-drive non-excitation brake, by setting up a servo motor, brake housing, electromagnetic device, and connecting semi-circular shell and closed semi-circular shell, allows the servo motor and the main structure of the non-excitation brake, the brake housing and the electromagnetic device to be directly connected as a whole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 A direct-drive non-excitation brake includes: a servo motor 1, a motor cover 2 fixedly connected to the outer wall of the servo motor 1, a motion control shaft disk 3 provided on the outer wall of the servo motor 1, a brake housing 4 provided on the outer wall of the motion control shaft disk 3, a connecting semi-circular shell 5 fixedly connected to the outer wall of the brake housing 4, an expansion cover 6 connected to the outer wall of the connecting semi-circular shell 5, a screw hole 7 opened on the inner wall of the expansion cover 6, an arc groove 8 opened on the inner wall of the connecting semi-circular shell 5, a closed semi-circular shell 9 provided on one side of the connecting semi-circular shell 5, a screw 10 threadedly connected to the inner wall of the closed semi-circular shell 9, an electromagnetic device 11 sleeved in the inner cavity of the brake housing 4, an electromagnetic coil 12 provided in the inner cavity of the electromagnetic device 11, a main shaft 13 provided on the inner wall of the brake housing 4, a rotating shaft 14 connected to the outer wall of the main shaft 13, a spring 15 connected to the inner wall of the electromagnetic device 11, and a brake pad 16 provided on one side of the spring 15.

[0023] The outer wall of the motion control shaft disk 3 is semi-circular, and the size of the outer wall of the motion control shaft disk 3 is adapted to the inner wall of the arc groove 8. Because the outer wall of the motion control shaft disk 3 is semi-circular, the connecting semi-circular shell 5 on the device is first fastened to the outer wall of the motion control shaft disk 3. The inner wall of the arc groove 8 is highly matched with the outer wall of the motion control shaft disk 3, so that the connecting semi-circular shell 5 on the device can be completely matched with the motion control shaft disk 3.

[0024] Among them, the screw hole 7 penetrates the outer wall of both the closed semi-circular shell 9 and the expansion cover 6, and the inner wall of the expansion cover 6 is adapted to the outer wall of the screw 10. By having the screw hole 7 penetrate the outer wall of both the closed semi-circular shell 9 and the expansion cover 6, the screw hole 7 is opened on the outer wall of the expansion cover 6 and the closed semi-circular shell 9. At the same time, the symmetrically arranged reserved holes provide space for the connection of the screw 10. Thus, when the closed semi-circular shell 9 is fastened to the other half of the outer wall of the motion control shaft disk 3, the screw hole 7 and the screw 10 are used to fix the closed semi-circular shell 9 and the connecting semi-circular shell 5 and the expansion cover 6.

[0025] The expansion cover 6 is simultaneously disposed on the outer wall of the connecting semicircular shell 5 and the closed semicircular shell 9, and an "L"-shaped top cover is added to the outer wall of the connecting semicircular shell 5. By having the expansion cover 6 simultaneously disposed on the outer wall of the connecting semicircular shell 5 and the closed semicircular shell 9, when the closed semicircular shell 9 and the connecting semicircular shell 5 complete a circular closure, the "L"-shaped top cover of the expansion cover 6 on the device will seal the overlapping part of the connecting semicircular shell 5 and the closed semicircular shell 9, thereby closing the gap between the closed semicircular shell 9 and the connecting semicircular shell 5.

[0026] The electromagnetic device 11 is movably sleeved on the outer wall of the main shaft 13, and the inner wall of the electromagnetic device 11 is larger than the outer wall of the main shaft 13. By movably sleeved on the outer wall of the main shaft 13, the electromagnetic device 11 is sleeved on the outer wall of the main shaft 13 without interfering with the rotation of the main shaft 13, thereby maintaining a small gap between the electromagnetic device 11 and the main shaft 13.

[0027] The electromagnetic coil 12 is in the shape of a ring and is completely enclosed in the inner cavity of the electromagnetic device 11. Because the electromagnetic coil 12 is in the shape of a ring, it can perform excellent functions such as emergency braking, maintaining a stopped state, and preventing mechanical idling when the electromagnetic coil 12 is energized or de-energized in the inner cavity of the electromagnetic device 11.

[0028] There are four springs 15, and the four springs 15 are arranged in the inner cavity of the electromagnetic device 11. Through the four springs 15 on the device, the springs 15 on the device push the brake pad 16 to make close contact with the brake disc 17 in the inner cavity of the electromagnetic device 11, generating friction to stop the movement of the rotating shaft. When energized, the electromagnetic force attracts the brake pad 16, causing it to separate from the brake disc 17, thereby releasing the braking force.

[0029] The brake pad 16 is connected to the brake disc 17 on its outer wall, and the diameter of the brake disc 17 is the same as that of the brake pad 16. By connecting the brake pad 16 to the brake disc 17 on the device, the brake pad 16 can make complete contact with the outer wall of the brake disc 17 when braking, so that the friction force can be fully transmitted to the brake disc 17, thereby enabling the braking force of the brake pad 16 to accurately control the brake disc 17.

[0030] The working principle is as follows: First, by setting up structures such as servo motor 1, brake housing 4, electromagnetic device 11, connecting semi-circular shell 5, and closed semi-circular shell 9, the servo motor 1 and the main structure of the non-excitation brake, brake housing 4 and electromagnetic device 11 are directly connected as a whole. The connecting semi-circular shell 5 and closed semi-circular shell 9 are fastened to the outer wall of the motion control shaft disk 3, so that when the servo motor 1 and the non-excitation brake are directly connected, the connecting semi-circular shell 5 and closed semi-circular shell 9 are completely fastened together. Then, by setting up structures such as connecting semi-circular shell 5, closed semi-circular shell 9 and expansion cover 6, when the two sides of the motion control shaft disk 3 are fastened with connecting semi-circular shell 5 and closed semi-circular shell 9, the expansion cover 6 on the device provides a top seal in the overlapping area between connecting semi-circular shell 5 and closed semi-circular shell 9, thereby preventing external water stains or impurities from entering the interior at the gap between closed semi-circular shell 9 and connecting semi-circular shell 5.

[0031] 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.
