Description

Technical Field

[0001] This utility model belongs to the field of clutch technology, and in particular relates to a vertically mounted single-plate electromagnetic clutch. Background Technology

[0002] Currently, known dry-plate single-plate electromagnetic clutches use a 24V or 12V DC power supply to control the engagement and disengagement of power transmission. An electromagnetic coil generates a magnetic field that attracts the armature to the friction plates. Torque is transmitted through the friction between the friction plates and the armature, meaning power is transferred from the shaft through the friction plates to the armature, and then to the components connected to the armature (components can be couplings, discs, sprockets, gears, pulleys, etc.). Dry-plate single-plate electromagnetic clutches are typically used in horizontal installations, with internal support usually consisting of deep groove ball bearings. However, in vertical applications, where the clutch must bear the weight of the components, the deep groove ball bearing cannot support this load. This can cause the clutch to lose its original installation clearance, potentially resulting in the armature and friction plates contacting each other even without power, thus losing its engagement / disengagement function.

[0003] Therefore, it is necessary to provide a new vertically mounted single-plate electromagnetic clutch to solve the above-mentioned technical problems. Utility Model Content

Figure 1 ; Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 ; Figure 3 This is a schematic diagram of the armature end in this utility model; Figure 4 This is a schematic diagram of the clutch friction plate in this utility model; Figure 5 This is a schematic diagram of the clutch coil end in this utility model. The vertically mounted single-plate electromagnetic clutch includes: a limiting plate (1), an internal hexagon screw (2), a dry single-plate electromagnetic clutch (3), a bearing (4), a flat key (5), an adapter bushing (6), a first retaining ring for the bore (7), an adapter flange (8), a spacer ring (9), a second retaining ring for the bore (10), an angular contact bearing (11), a retaining ring for the shaft (12), and bolts (13).

[0025] The dry single-plate electromagnetic clutch (3) comprises several parts, including a clutch coil end (17), a clutch friction plate (18), and an armature end (19).

[0026] The clutch friction plate (18) is mounted on the clutch coil end (17), and a snap ring groove is provided on the clutch coil end (17). The hole is fitted with a retaining ring (7) into the snap ring groove and is adapted to the snap ring groove.

[0027] The bearing (4) is installed into the limiting plate (1), and the clutch coil end (17) is installed on the limiting plate (1) by the internal hex screw (2). The clutch coil end (17) is adapted to the bearing (4).

[0028] The adapter sleeve (6) has a keyway, and the flat key (5) is inserted into the keyway and is adapted to the keyway.

[0029] The adapter sleeve (6) passes through the bearing (4), the clutch coil end (17) and the clutch friction plate (18) and is adapted to the bearing (4), the clutch coil end (17) and the clutch friction plate (18). The bottom of the adapter sleeve (6) is level with the bottom of the limiting plate (1). The adapter sleeve (6) is located above the bearing (4).

[0030] The clutch friction plate (18) has a second keyway, which is adapted to the flat key (5).

[0031] The angular contact bearing (11) is installed in the bearing hole of the transition flange (8), and the hole is fitted with a retaining ring two (10) into the through hole on the bearing end face of the transition flange (8). The armature end (19) is connected to the transition flange (8) by bolts (13).

[0032] The spacer ring (9) is mounted on the outer circle of the adapter sleeve (6), the angular contact bearing (11) is mounted on the outer circle of the adapter sleeve (6), and the shaft retaining ring (12) is mounted on the angular contact bearing (11).

[0033] Measure the difference between the actual clutch clearance and the standard clearance, and adjust the clutch clearance to the required size by grinding the width of the spacer ring (9).

[0034] A matching power end shaft (16) can be inserted into the adapter sleeve (6), and a threaded hole (14) is provided on the adapter flange (8). The threaded hole (14) on the adapter flange (8) is connected to a component (15) by screws.

[0035] When the electromagnetic coil in the clutch coil end (17) of the dry single-plate electromagnetic clutch (3) is energized, a magnetic field is generated. This magnetic field will attract the armature end (19), causing the armature end (19) to overcome a certain resistance and move toward the clutch friction plate (18) and fit tightly. Since the clutch friction plate (18) is installed on the clutch coil end (17) and the two are fixed and limited by the retaining ring (7) through the hole, after the armature end (19) contacts the clutch friction plate (18), the torque is transmitted by the friction force generated between the two.

[0036] The power end shaft (16) is inserted into the adapter sleeve (6). The adapter sleeve (6) is circumferentially fixed to the clutch friction plate (18) by the flat key (5), ensuring that the rotation of the power end shaft (16) can be transmitted to the clutch friction plate (18). At this time, the power is transmitted from the power end shaft (16) through the adapter sleeve (6) and the clutch friction plate (18) to the armature end (19), and then through the component (15) connected by the threaded hole (14) on the adapter flange (8), the power is transmitted to the required working parts to realize the power transmission.

[0037] The bearing (4) and the angular contact bearing (11) play a supporting role and reduce rotational friction, ensuring the stable operation of each component of the clutch. In particular, the angular contact bearing (11) can withstand the weight load of the components in the vertical direction, ensuring that the clutch can maintain a stable installation gap and normal switching function when installed vertically.
