Description

Technical Field

[0001] The utility model relates to the technical field of power assembly, in particular to a novel electromagnetic clutch structure. Background Art

[0002] An electromagnetic clutch is a device that uses the principle of electromagnetic induction and the friction between the inner and outer friction plates to achieve transmission. When the coil is energized, an electromagnetic force is generated to compress the inner and outer friction plates, thereby transmitting the torque of the active component to the driven component. When the coil is de-energized, the electromagnetic force disappears, the inner and outer friction plates separate, and the transmission stops.

[0003] The traditional internal connection method of electromagnetic clutch mainly relies on electromagnetic principle and friction to realize power transmission. Specifically, when the electromagnetic clutch is energized, the electromagnetic coil will generate a strong electromagnetic field, which will attract the armature inside the clutch, that is, the iron sheets that can be attracted by magnetic force. Under the action of electromagnetic force, multiple armatures will be pressed tightly together to form a compact friction surface. When the active part rotates, this friction field will transmit power to the driven part, causing it to rotate with it. This transmission method depends on the stability and strength of friction. Therefore, the selection of friction materials and the design of armatures are crucial.

[0004] When using an armature connection to transmit power through friction, problems such as friction overheating and slipping may occur. This is because when the armature transmits power through friction, a large amount of heat will be generated on the friction surface. If this heat cannot be dissipated in time, it will cause the local temperature to rise and may even reach a critical temperature that causes changes in material properties. Overheating will not only affect the performance of the clutch, but may also cause thermal damage to other surrounding components. In addition, slipping is another potential problem. Slipping usually occurs when the friction force is insufficient to maintain stable transmission. This may be due to insufficient pressure between the friction surfaces, reduced friction coefficient, or excessive temperature that causes the friction material performance to deteriorate. Slipping will not only reduce transmission efficiency, but also accelerate the wear of the friction surface and shorten the service life of the clutch. Utility Model Content
