According to the shaft type, there are: double-shaft magnetic powder clutch, hollow shaft magnetic powder clutch, hollow shaft magnetic powder clutch.

[0003] After searching, the announcement number is CN217873875U, which discloses a magnetic powder clutch heat dissipation device, including a magnetic powder clutch body, the outer wall of the magnetic powder clutch body is slidably connected to a shell, one side of the outer wall of the shell is fixedly connected to a box, a motor is fixedly connected inside the box, one end of the motor output shaft is fixedly connected to a driving shaft, a rotating plate is fixedly connected to the top of the driving shaft, and a slider is fixedly connected to the top of the rotating plate. The utility model is provided with a rotating plate on the driving shaft, a slide groove on the outer wall of the movable plate, a slider inside the slide groove, a first rack and a second rack between the movable block and the moving rod, and an extrusion block inside the first groove, so that the moving rod can slide on the outer wall of the fixed rod. In the utility model, the heat generated by the magnetic powder clutch body during use can be dissipated in time, so that the magnetic properties of the magnetic powder will not be weakened, thereby improving the function of the magnetic powder clutch.

[0004] Although this patented technology solves the problem that the heat generated by the existing magnetic powder clutch body during use can be dissipated in time, so that the magnetic properties of the magnetic powder will not be weakened, thereby improving the function of the magnetic powder clutch, it does not solve the problem of preventing external dust from entering and causing parts failure while dissipating heat. Therefore, technicians in this field provide a magnetic powder clutch heat dissipation device to solve the problems raised in the above background technology. Summary of the invention

[0005] In order to make up for the above shortcomings, the utility model provides a magnetic powder clutch heat dissipation device, aiming to improve the problem in the prior art that while releasing heat, it is unable to prevent external dust from entering and causing parts failure.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A magnetic powder clutch heat dissipation device comprises a shell, a bearing is fixedly connected to the outside of the shell, a magnetic roller mouth is arranged on the outside of the bearing, an output shaft is rotatably connected to the middle of the bearing, heat dissipation components are arranged at the four corners of the shell, the heat dissipation components include heat dissipation fins, fans are fixedly connected to the outsides of the heat dissipation fins, heat dissipation grooves are arranged on the inner sides of the heat dissipation fins, a heat dissipation port is arranged at the bottom of the heat dissipation grooves, and a filter is arranged on the top of the heat dissipation port.

[0008] Through the above technical solution, when the shell is working, heat is generated, and the heat inside the device is discharged through the heat dissipation port. The heat is distributed on the heat dissipation fins through the heat dissipation port at the bottom of the heat dissipation slot, thereby releasing all the heat to the maximum extent. While releasing the heat, dust is filtered through the filter. The filter can prevent external dust from entering the heat dissipation port and causing part failure. The fan is started and the fan rotates, making it easier for the heat to be transferred from the heat dissipation fins to the air. In this way, the heat transfer rate between the heat dissipation fins and the outside air is maintained at a high level, which can improve the heat dissipation effect of the radiator.

[0010] Through the above technical solution, by arranging the driven body on the inner side of the driving body and fixing a baffle on the outer side of the driven body, a relatively closed space is formed between the driven body and the driving body to prevent magnetic powder from scattering to the outside, resulting in uneven distribution of magnetic powder and insensitive operation of the device. By arranging magnetic powder inside the magnetic gap, when the coil is energized, the magnetic yoke generates magnetism, which causes the magnetic powder between the driven body and the driving body to attract each other, prompting the driven body and the driving body to be connected to each other, thereby realizing the transmission of torque.

[0011] Furthermore, a retaining spring is arranged on the outside of the output shaft, and the retaining spring is fixedly connected to the inside of the bearing.

[0012] Through the above technical solution, a retaining spring is provided to prevent the bearing from sliding and reduce the vibration generated during the operation of the device.

[0013] Furthermore, the baffle is fixedly connected to the left part of the driving body.

[0014] Through the above technical solution, a relatively closed space is formed between the driven body and the driving body to prevent magnetic powder from scattering to the outside.

[0015] Furthermore, the filter is fixedly connected to the inside of the heat dissipation slot.

[0016] Through the above technical solution, dust is filtered through the filter, and the filter can prevent external dust from entering the heat dissipation port and causing parts failure.

[0017] Furthermore, a stabilizing block is provided on the right portion of the shell.

[0018] Through the above technical solution, the device is kept stable by setting the stabilizing block.

[0019] Furthermore, the baffle is rotatably connected to the lower part of the magnetic powder.

[0020] Through the above technical solution, a relatively closed space is formed between the driven body and the driving body to prevent magnetic powder from scattering to the outside.

[0021] The utility model has the following beneficial effects:

[0022] In the utility model, the shell, the heat dissipation port, the heat dissipation slot, the heat dissipation fins, the filter screen and the fan are coordinated to release heat while preventing external dust from entering and causing parts failure.

[0023] In the utility model, by cooperating among structures such as the driving body, the driven body, the baffle, the magnetic powder, the magnetic yoke, the mounting groove and the wire package, it is possible to prevent the magnetic powder from scattering to the outside, resulting in uneven distribution of the magnetic powder and insensitive operation of the device, thereby achieving torque transmission.
