Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic clutches, in particular to an electromagnetic clutch pulley structure which is easy to maintain. Background Art

[0002] The electromagnetic clutch usually includes a coil assembly, a pulley and a drive disc. Its working process is that when the coil assembly is energized, the electric coil assembly will generate magnetic force, and the drive disc and the pulley will produce friction for braking. When the coil assembly is energized, the electric coil assembly will not generate magnetic force, and the drive disc and the pulley will separate.

[0003] According to the patent of announcement number CN208982542U, a pulley of an electromagnetic clutch is proposed. The pulley of the electromagnetic clutch can reduce the phenomenon of belt disjoint during use of the pulley by setting a V-shaped groove. The ball bearing and the setting of the entire pulley are conveniently fixed by the cooperation of rivets and covers, so that the armature ring and the annular suction cup are kept at a suitable distance, which is convenient for clutching. When the electromagnetic coil is energized, a strong adsorption force is generated, so that the armature ring approaches the annular suction cup, and strip protrusions are equidistantly arranged on the right side of the armature ring, and rubber protrusions are equidistantly arranged on the left side of the annular suction cup, so that the friction between the armature ring and the annular suction cup can be enhanced by the mutual cooperation of the strip protrusions and the rubber protrusions, thereby strengthening the braking effect. When the electromagnetic coil loses its magnetic force when it is powered off, the armature ring can be restored to its original position by means of the rebound effect of the spring and the butterfly spring in the telescopic assembly, and the position of the armature ring of the column can be limited to a certain extent by the setting of the pressure plate, so that the position of the armature ring and the annular suction cup is maintained at a suitable position.

[0004] However, the pulley of the electromagnetic clutch has no heat dissipation structure, and the electromagnetic clutch working for a long time is likely to cause the coil temperature to be too high, resulting in the electromagnetic clutch overheating protection, malfunctioning and other problems. Therefore, an easy-to-maintain electromagnetic clutch pulley structure is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Among them, a heat conduction pipe 204 is fixedly installed inside the pulley body 202, and the heat of the pulley body 202 is absorbed by the heat conduction pipe 204. A heat pipe ring 203 is fixedly installed on the right side of the heat conduction pipe 204, and the heat of the electromagnetic clutch body 201 is absorbed by the heat pipe ring 203. The inner surface of the heat pipe ring 203 is rotatably installed with the outer surface of the electromagnetic clutch body 201.

[0023] Among them, a heat sink 205 is fixedly installed on the left side of the pulley body 202. The heat sink 205 includes a partition heat sink and an incremental heat sink. The partition heat sink and the incremental heat sink are evenly distributed when viewed from the left side. The heat pipe ring 203 and the conductive heat pipe 204 dissipate heat through the heat sink 205.

[0024] Among them, the left side of the heat sink 205 is tightly fitted with a mounting plate 206, the left side of the mounting plate 206 is fixedly installed with an electric fan 207, and the left side of the mounting plate 206 is fixedly installed with a dustproof mesh cover 208. The electric fan 207 allows air to be filtered by the dustproof mesh cover 208 before entering the interior of the heat sink 205.

[0025] Specifically, when the electromagnetic clutch body 201 is running, the heat of the electromagnetic clutch body 201 is absorbed by the heat pipe ring 203, and the heat of the pulley body 202 is absorbed by the conductive heat pipe 204, so that the heat pipe ring 203 and the conductive heat pipe 204 dissipate heat through the heat sink 205, and the electric fan 207 is started to allow air to be filtered by the dustproof mesh cover 208 and then enter the heat sink 205, and quickly dissipate heat through the heat sink 205 and the mounting plate 206, thereby preventing the coil temperature of the electromagnetic clutch from being too high and ensuring the normal operation of the electromagnetic clutch.

[0026] Example 2: Please refer to Figure 1 and Figure 2 On the basis of the first embodiment, the disassembly and assembly mechanism 3 includes an insertion rod 301, the right side of the insertion rod 301 is fixedly connected to the left side of the pulley body 202, the left side of the mounting plate 206 is fixedly mounted with a housing 302, a slot is opened inside the mounting plate 206, the inner surface of the slot is slidably connected to the outer surface of the insertion rod 301, and the mounting plate 206 is installed through the insertion rod 301.

[0027] Among them, a spring rod 303 with one end penetrating and extending into the interior of the insertion rod 301 is slidably installed inside the shell 302, and the insertion rod 301 and the mounting plate 206 are fixed by the spring rod 303. A mounting ring 304 is fixedly installed on the outer surface of the spring rod 303, and a columnar spring 305 is slidably installed on the outer surface of the spring rod 303.

The columnar spring 305 prevents the spring rod 303 from rebounding and falling out through the mounting ring 304.

[0028] Specifically, the mounting plate 206 is installed by the insertion rod 301, and the insertion rod 301 and the mounting plate 206 are fixed by the spring rod 303. The cylindrical spring 305 prevents the spring rod 303 from rebounding and falling out through the mounting ring 304, which facilitates the cleaning of the heat sink 205 and meets the user's usage needs.

[0029] The working principle of the above embodiment is:

[0030] (1) When the electromagnetic clutch body 201 is running, the heat of the electromagnetic clutch body 201 is absorbed by the heat pipe ring 203, and the heat of the pulley body 202 is absorbed by the heat conduction pipe 204, so that the heat pipe ring 203 and the heat conduction pipe 204 dissipate heat through the heat sink 205.

[0031] (2) The mounting plate 206 is installed by means of the insertion rod 301, and the insertion rod 301 and the mounting plate 206 are fixed by means of the spring rod 303. The cylindrical spring 305 prevents the spring rod 303 from rebounding and falling out through the mounting ring 304. The electric fan 207 is started so that the air is filtered by the dustproof mesh cover 208 and then enters the interior of the heat sink 205, and the heat is quickly dissipated through the heat sink 205 and the mounting plate 206.
