Description

Technical Field

[0001] The utility model belongs to the technical field of electromagnetic clutch shells, and more specifically, particularly relates to an explosion-proof electromagnetic clutch shell. Background Art

[0002] The electromagnetic clutch is a speed regulating device that relies on the on and off of the coil to control the engagement and disengagement of the clutch. The electromagnetic clutch can be divided into dry single-plate electromagnetic clutch, dry multi-plate electromagnetic clutch, wet multi-plate electromagnetic clutch, magnetic powder clutch, slip electromagnetic clutch, etc. According to the working mode, it can be divided into power-on combination and power-off combination. The existing electromagnetic clutch lacks an explosion-proof structure when in use. If the electromagnetic clutch explodes, the power of the explosion cannot be underestimated, which can easily cause a fire and may cause casualties in severe cases.

[0003] Patent application number CN202122205748.3 discloses an explosion-proof electromagnetic clutch housing, which solves the problem that when the existing electromagnetic clutch is in use, due to the lack of explosion-proof structure of the electromagnetic clutch, if the electromagnetic clutch explodes, the power of the explosion cannot be underestimated, it is easy to cause a fire, and in serious cases, it may cause casualties. It includes an explosion-proof housing, an electromagnetic clutch body is arranged inside the explosion-proof housing, one end of the electromagnetic clutch body is connected to a first connecting shaft, and the other side of the electromagnetic clutch body is connected to a second connecting shaft, an explosion-proof top shell is hinged on one side of the top opening of the explosion-proof housing through a hinge, a storage box is arranged on the top of the internal top of the explosion-proof top shell, the interior of the storage box is filled with fire extinguishing sand, a pressure plate is arranged on the top of the storage box, and a mounting frame is threadedly connected to the bottom of the storage box, and the internal top opening of the mounting frame A discharge port is provided, and a sealing cover is provided at the bottom opening of the discharge port. A pair of retaining sleeves are provided at the bottom of the sealing cover and the inner top of the mounting frame, and a thermal expansion glass tube is provided between the pair of retaining sleeves. The utility model has a simple and reasonable structure, a novel design, and simple and convenient operation. It can effectively improve the safety of the electromagnetic clutch and avoid the occurrence of fire. It has high practical value. However, the electromagnetic clutch will generate more heat during operation. When the explosion-proof housing in the above technical scheme is in use, the heat generated by the electromagnetic clutch during operation will accumulate in the explosion-proof housing, which will cause a large amount of heat accumulation under long-term use, increasing production risks. In addition, when the electromagnetic clutch is installed on some mechanical equipment, the mechanical equipment will generate vibration when started, and the direct collision of external objects on the electromagnetic clutch will easily cause damage to the electromagnetic clutch, increasing maintenance costs.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an explosion-proof electromagnetic clutch housing is provided to achieve a more practical purpose. Utility Model Content

[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 4 As shown:

[0027] The utility model provides an explosion-proof electromagnetic clutch housing, comprising an outer shell 1, a plurality of vents 2 are symmetrically arranged on both sides of the outer shell 1, a mounting groove 3 is arranged inside the outer shell 1, a pair of first slide grooves 4 are arranged on both sides of the mounting groove 3 at positions close to the plurality of vents 2, a blocking plate 5 is slidably installed between each pair of first slide grooves 4, a plurality of ventilation grooves 6 are penetrated through one side of the blocking plate 5, a thermal expansion glass tube 7 is installed at the bottom end between each pair of first slide grooves 4, a placement groove 8 is provided at the bottom end of the mounting groove 3, a plurality of second slide grooves 9 are arranged on four sides of the placement groove 8, an electromagnetic clutch body 10 is installed in the placement groove 8, a plurality of sliders 11 are arranged on four sides of the bottom end of the electromagnetic clutch body 10, and a flame retardant mechanism 12 is installed at the top of the mounting groove 3.

[0028] Among them, the positions and sizes of several ventilation grooves 6 match the positions and sizes of several vents 2. When no combustion occurs, the positions of the ventilation grooves 6 are aligned with the positions of the vents 2. At this time, the air inside and outside the outer shell 1 can circulate through the vents 2 and the ventilation grooves 6, so that the heat accumulated inside the outer shell 1 can be discharged, and the staff can improve the heat dissipation effect by setting an external wind source.

[0029] Among them, the top end of the heat expansion glass tube 7 is in close contact with the bottom end of the blocking plate 5. When combustion occurs, the temperature around the heat expansion glass tube 7 increases, causing the heat expansion glass tube 7 to rupture. At this time, the blocking plate 5 is no longer limited by the heat expansion glass tube 7, and slides downward in a pair of first slide grooves 4, so that the solid part of the blocking plate 5 without the ventilation groove 6 is in contact with the vent 2 to prevent the flame from escaping from the vent 2. At the same time, the air can also be isolated and blocked to reduce the oxygen content inside the outer shell 1.

[0030] Among them, a plurality of sliding blocks 11 are slidably connected to a plurality of second sliding grooves 9 respectively.

[0031] Among them, a spring 13 is installed on the peripheral side of the slider 11, and the other end of the spring 13 is connected to one side of the second slide groove 9. When the outer shell 1 is hit and the electromagnetic clutch body 10 shakes and moves, the slider 11 at the bottom end of the electromagnetic clutch body 10 moves in the second slide groove 9, squeezing the spring 13, causing the spring 13 to deform, and converting the kinetic energy generated by the shaking movement into the elastic potential energy of the spring 13, thereby achieving buffering.

[0032] The outer shell 1 is provided with a water baffle 14 at a position directly above each vent 2 .

[0033] The outer shell 1 is made of aluminum alloy, which improves the heat dissipation effect of the outer shell 1.

[0034] The working principle of this embodiment is as follows: the staff first installs the electromagnetic clutch housing to the designated position, at which time the position of the ventilation slot 6 is aligned with the position of the ventilation port 2, and the air inside and outside the outer shell 1 can circulate through the ventilation port 2 and the ventilation slot 6, so that the heat accumulated inside the outer shell 1 can be discharged, and the staff can improve the heat dissipation effect by setting an external wind source. When the electromagnetic clutch is damaged and explodes and burns, the temperature around the thermal expansion glass tube 7 rises, causing the thermal expansion glass tube 7 to rupture. At this time, the blocking plate 5 is no longer limited by the thermal expansion glass tube 7, and slides downward in a pair of first slide grooves 4, so that the blocking plate The solid part without ventilation groove 6 is fitted with ventilation opening 2 to prevent flame from escaping from ventilation opening 2, isolate and block air, reduce oxygen content inside outer shell 1, and flame retardant mechanism 12 can extinguish flame inside outer shell 1 to prevent greater risk and loss caused by continuous combustion. When the electromagnetic clutch is used, when outer shell 1 is hit, slider 11 at the bottom of electromagnetic clutch body 10 moves in second slide groove 9, squeezes spring 13, deforms spring 13, converts kinetic energy generated by shaking movement into elastic potential energy of spring 13, realizes buffering, and prolongs service life of electromagnetic clutch.

Many modifications and variations will be apparent to those of ordinary skill in the art.
