Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a fixed-point clutch. Background Art

[0002] A fixed-point clutch is a device commonly used in mechanical transmission systems. Its main function is to control the transmission and separation of power. Existing fixed-point clutches are prone to internal slippage during the power transmission process, which affects their performance.

[0003] To overcome these drawbacks, a prior art Chinese patent (publication number: CN106704406B) discloses an electromagnetic clutch comprising an electromagnetic fixed plate, an electromagnetic rotating plate, an excitation coil, a first linkage member, a second linkage member, several bearings, and a flange. The first linkage member is a disc-shaped body with a tapered circumference and an annular arrangement of gear teeth. A through-hole is provided in the axial direction of the first linkage member. The second linkage member is also a disc-shaped body with a through-hole in the middle. The circumference of the through-hole forms meshing gear teeth that match the shape and size of the first linkage member's outer hub. Force transmission is achieved through the combination of the first and second linkage members. The first and second linkage members utilize gear-tooth meshing, resulting in a large contact area and a wide overall force-bearing area. This reduces slippage during force transmission, improving stability and reliability. This invention belongs to the field of clutch device technology.

[0004] Although the existing technology can overcome the above-mentioned shortcomings, there are still other problems in its operation: when the above-mentioned clutch realizes the clutch function, the clutch function is realized by connecting and separating the grooves between the gears and the gears that are meshed with each other. Misalignment may occur during the transmission process between the gears and the grooves, which can easily cause the gears and the grooves to produce friction for a long time, resulting in accelerated wear of the internal parts of the clutch.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1 - Figure 6The present invention provides the following technical solutions: a fixed-point clutch, comprising a wire seat 1 and an input rotor 2, a clutch positioning plate 3 and an output flange 4, wherein the wire seat 1 and the input rotor 2 constitute an active structure interconnected with the motor, and the clutch positioning plate 3 and the output flange 4 constitute a driven structure interconnected with the equipment; a clutch structure is provided between the driven structure and the active structure, and the clutch structure comprises an input rotor 2 and a clutch positioning plate 3 which are fitted together, and three mounting holes 5 are provided in an annular arrangement inside the clutch positioning plate 3, and each mounting hole 5 is provided in an annular arrangement. The holes 5 are all rotatably connected with rotating shafts 6, and the ends of the three rotating shafts 6 are all facing the center of the clutch positioning plate 3. Three positioning holes 7 distributed in a ring are provided on the side of the input rotor 2 close to the clutch positioning plate 3, and the positioning holes 7 and the mounting holes 5 are aligned with each other, and the rotating shafts 6 are engaged and connected to the inside of the positioning holes 7; a main meshing ring 8 is provided at the edge of one side of the input rotor 2 close to the clutch positioning plate 3, and a secondary meshing ring 9 is provided at the edge of one side of the clutch positioning plate 3 close to the input rotor 2, and the main meshing ring 8 and the secondary meshing ring 9 are meshed with each other.

[0026] When the input rotor 2 is in contact with the clutch positioning plate 3, the wire seat 1 is energized, and a magnetic force is generated through the coil inside the drive sleeve 11. Under the action of this magnetic force, the clutch positioning plate 3 is pulled toward the input rotor 2, so that the two are in contact. During this process, the main meshing ring 8 on the outside of the input rotor 2 and the secondary meshing ring 9 on the outside of the clutch positioning plate 3 are meshed with each other, thereby connecting the input rotor 2 and the clutch positioning plate 3 as a whole. At this time, the meshing of the main meshing ring 8 and the secondary meshing ring 9 can transmit the power of the input rotor 2 to the clutch positioning plate 3, and finally to the output flange 4.

[0027] During the process of the input rotor 2 being fitted with the clutch positioning plate 3, the grooves and protrusions of the primary meshing ring 8 and the secondary meshing ring 9 will be gradually aligned. When the primary meshing ring 8 and the secondary meshing ring 9 are aligned, the end of the rotating shaft 6 close to the input rotor 2 will also be fitted with the clutch positioning plate 3. At the same time, the rotating shaft 6 rotates around its axis to support the input rotor 2 and the clutch positioning plate 3 to prevent them from being fully fitted prematurely.

[0028] Since the rotating shaft 6 and the positioning hole 7 are connected by a snap-fit ​​connection, the main meshing ring 8 and the auxiliary meshing ring 9 must be in a meshing state. In addition, the distribution of each rotating shaft 6 and the positioning hole 7 on the clutch positioning plate 3 and the input rotor 2 is irregular, so each positioning hole 7 can only be aligned with a unique corresponding rotating shaft 6. Only when all rotating shafts 6 are aligned with the positioning holes 7 at the same time can a reliable snap-fit ​​connection between the rotating shaft 6 and the positioning holes 7 be achieved.

[0029] After the rotating shaft 6 is connected to the positioning hole 7, the rotating shaft 6 is completely embedded in the positioning hole 7. At this time, the rotating shaft 6 will lose its supporting function on the input rotor 2 and the clutch positioning plate 3, so that the input rotor 2 and the clutch positioning plate 3 can fit tightly. At the same time, the main meshing ring 8 and the auxiliary meshing ring 9 complete the meshing, realizing the power transmission between the input rotor 2 and the clutch positioning plate 3.

[0030] Embodiment 2: Based on embodiment 1, an active structure and a driven structure are also disclosed, and their specific structures are as follows: the active structure includes a wire seat 1 and an input rotor 2 that are connected to each other, and a reserved hole 10 is provided in the middle of the wire seat 1, and a drive sleeve 11 is fixedly connected in the middle of the input rotor 2; the drive sleeve 11 is rotatably connected to the middle of the reserved hole 10, and the output end of the motor extends through the reserved hole 10 to the inside of the drive sleeve 11, and the output end of the motor is fixedly connected to the inside of the drive sleeve 11; the driven structure includes a clutch positioning plate 3 and an output flange 4 that are connected to each other, and the output flange 4 is snap-connected to the clutch positioning plate 3 away from the input Inside one side of the input rotor 2; a positioning gear ring 12 of an annular structure is provided at the edge of the clutch positioning plate 3 away from the input rotor 2, and a positioning gear 13 is fixedly connected to the outside of the output flange 4, and the positioning gear 13 is meshed with the inside of the positioning gear ring 12; the output flange 4 is provided with connecting holes 14 distributed in an annular shape and at equal intervals, and each connecting hole 14 is slidably connected to a fixing screw 15, the fixing screw 15 passes through the connecting hole 14 and extends to the inside of the clutch positioning plate 3, and the clutch positioning plate 3 is provided with a threaded hole 16 aligned with the connecting hole 14, and the fixing screw 15 is threadedly connected to the inside of the threaded hole 16.

[0031] During the use of the clutch, the motor output end is first passed through the reserved hole 10 and connected to the drive sleeve 11, and then the drive sleeve 11 is driven by the motor to rotate, and at the same time, the output flange 4 is connected to the driven device to complete the installation of the entire clutch.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
