Description

Technical Field

[0001] This utility model relates to the field of permanent magnet clutch technology, and in particular to a split clutch brake device and a clutch having the same. Background Technology

[0002] In the assembly of a precision cross-scissor permanent magnet clutch, the assembly of the brake component, due to the design characteristics of its drive shaft assembly (as shown in Figure 1), was originally performed by assembling the entire brake device from one end of the winding rotor shaft to the other, following the order of the first assembly, the brake disc, and the second assembly, from left to right or right to left. Then, the remaining components on the shaft end side were assembled sequentially. This method of assembling a single component is time-consuming and labor-intensive, especially posing a risk of damaging components during replacement. Therefore, this application proposes a split clutch brake device and a clutch incorporating it, improving the brake device portion of the clutch. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a split clutch brake device and a clutch having the same. Through the symmetrical split disc design, the shaft end components do not need to be disassembled one by one in the traditional way when disassembling and assembling the disc. The brake disc can be disassembled and assembled separately, which reduces the risk of damage to components during disassembly and improves work efficiency.

[0004] In a first aspect, this application proposes a split clutch brake device, comprising a disc-shaped disc body, which is split along a central axis and is divided into two symmetrical parts. The disc body has at least one first mounting hole in a direction perpendicular to the split plane of the central axis, and a reamed bolt and a lock nut are adapted to fit in the first mounting hole. The reamed bolt and the lock nut are adapted to fit in the first mounting hole and fasten the two symmetrical parts of the disc body. The disc body also has at least one second mounting hole in a direction parallel to the central axis, and a lock bolt and a nut threadedly connected to it are adapted to fit in the second mounting hole. The second mounting hole is opened at the connection between the two symmetrical parts of the disc body.

[0005] Furthermore, there are two first mounting holes arranged symmetrically.

[0006] Furthermore, there are two second mounting holes arranged symmetrically.

[0007] Furthermore, two symmetrical semi-connecting rings are provided in the second mounting hole of the disc body. When the disc body is combined, the two semi-connecting rings together form a hollow cylindrical shape, and steps are provided at both ends of the axial direction of the hollow cylindrical shape.

[0008] Secondly, this application also proposes a clutch, including a clutch body and a brake disc installed therein, the brake disc being specifically a split clutch brake device as described in any of the embodiments of the first aspect.

[0009] The beneficial effects of this utility model are as follows: The split clutch brake device and clutch provided by this utility model, through the symmetrical split disc design, eliminate the need to disassemble the shaft end components one by one in the traditional way when disassembling and assembling the disc, and can realize the individual disassembly and assembly of the brake disc, reducing the risk of damage to components during disassembly and improving work efficiency; and the design of the first mounting hole and the second mounting hole being perpendicular and parallel to the split surface, respectively, allows the disc to be fastened in two directions, resulting in stronger stability.

[0015] The split clutch and brake device provided by this utility model is used in permanent magnet clutches, such as... Figure 1 As shown, the clutch body 1 is equipped with a winding rotor 2. In the past, when assembling various parts, it was necessary to first install the first assembly 4, and then install the brake disc 3 and the second assembly 5. At the same time, when disassembling the brake disc 3, it was also necessary to first remove the first assembly 4 or the second assembly 5. Therefore, this application designs the brake disc 3 as a split type to solve the problem of cumbersome individual disassembly and assembly steps.

[0016] See Figure 2The split clutch brake device of this application includes a disc-shaped body 10, which is split along the central axis to divide the whole into two symmetrical parts. The disc body 10 has two symmetrical first mounting holes 11 in the direction perpendicular to the split plane of the central axis, and each first mounting hole 11 is fitted with a hinge bolt 12 and a lock nut 13. The hinge bolt 12 and the lock nut 13 are fitted together and fasten the two symmetrical parts of the disc body 10 in the first mounting holes 11.

[0017] like Figure 3 and Figure 4 As shown, the disc body 10 also has two second mounting holes 21 extending in a direction parallel to the central axis. Each second mounting hole 21 is fitted with an anti-loosening bolt 23 and a nut 24 threadedly connected to it. Specifically, the second mounting holes 21 are opened at the connection between two symmetrical parts of the disc body 10. Two symmetrical half-connecting rings 22 are provided in the second mounting holes 21 of the disc body 10. When the disc body 10 is combined, the two half-connecting rings 22 together form a hollow cylinder. Both axial ends of the hollow cylinder are provided with steps, which facilitate the tightening of the anti-loosening bolts 23 and nuts 24.

[0018] See Figure 4 In this embodiment, the outer side of the semi-connecting ring 22 has a lower edge structure to facilitate its fastening and installation onto the disc body 10. At the same time, the semi-connecting ring 22 needs to be split into two parts, i.e., it is a hollow cylindrical shape assembled from four parts. If the outer side of the semi-connecting ring 22 does not have a lower edge structure, the semi-connecting ring 22 can be directly welded or screwed onto the disc body 10. In this case, the semi-connecting ring 22 does not need to be split into two parts.

[0019] This utility model divides the disc body 10 into upper and lower parts, which can be disassembled and assembled separately in the clutch using the hinge bolt 12 and the anti-loosening nut 13. The upper and lower disc parts of the disc body 10 can be separated or assembled without disassembling the first assembly 4 and the second assembly 5. This eliminates the need to disassemble the clutch shaft port components one by one, reducing the risk of damage to components during disassembly, achieving time and cost reduction and efficiency improvement, with significant results. At the same time, the design of the first mounting hole 11 and the second mounting hole 21 secures the disc body 10 in two directions, improving the stability of the disc body 10 assembly.

[0020] In some other embodiments, the split clutch brake device provided by this invention can be used in clutches, especially permanent magnet clutches, such as... Figure 1 As shown, the brake disc 3, also known as the disc body 10, is installed between the first assembly 4 and the second assembly 5, both of which are mounted on the winding rotor 2. Through the design of the split brake disc 3, the brake disc 3 can be disassembled and installed separately without affecting the first assembly 4 and the second assembly 5 in the axial direction.

[0021] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
