Referring to fig. 1 to 6, fig. 1 is a clutch heat dissipation structure according to an embodiment of the present invention. Fig. 1 is a schematic structural diagram of a heat dissipation structure of a clutch according to an embodiment of the present invention; FIG. 2 is an enlarged schematic view at A in FIG. 1; FIG. 3 is an exploded view of FIG. 1; FIG. 4 is an assembly view of a clutch end cap, a blade, and a blade securing block provided in accordance with an embodiment of the present invention; FIG. 5 is a schematic view of the clutch end cap, the vane, and the vane retaining block assembled in another orientation in accordance with an embodiment of the present invention; fig. 6 is a schematic view illustrating an assembly of a blade and a blade fixing block according to an embodiment of the present invention.

The invention provides a clutch heat dissipation structure, which comprises a first shell 5 and a second shell 1 which are used for assembling a clutch shell, wherein a clutch main body 11 and a clutch end cover 2 are arranged in the clutch shell, and the clutch end cover 2 is arranged on one side, close to the first shell 5, of the clutch main body 11; the wind power generator further comprises a plurality of blades 3 mounted on the clutch end cover 2 and a baffle plate 4 arranged on one side of the blades 3 close to the first shell 5.

The first shell 5 and the second shell 1 are respectively provided with half clutch cavities, and the first shell 5 and the second shell 1 are spliced oppositely to form a complete clutch cavity. A clutch body 11 and a clutch end cap 2 are installed in the clutch cavity, the clutch body 11 is close to the second housing 1, and the clutch end cap 2 is close to the first housing 5.

All the blades 3 are provided to the clutch end cover 2. When the clutch cover 2 rotates with the clutch body 11, all the blades 3 on the clutch cover 2 rotate in synchronization, and the blades 3 suck air from the first casing 5 side and discharge the air to the second casing 1 side.

The baffle 4 is disposed between all the blades 3 and the first casing 5. The baffle 4 restricts the flow direction of the air when the air enters from the first shell 5 into the blade 3 on one hand, and prevents the reverse flow of the air from flowing to one side of the first shell 5 after the air is discharged by the blade 3 on the other hand, so that the blade 3 forms a stable flow direction from the first shell 5 to the second shell 1 in the clutch shell, and the air flow rate and the cooling effect in the clutch shell are improved.

The clutch heat dissipation structure provided by the invention is further described below with reference to the accompanying drawings and embodiments.

In order to fully cool the inside of the clutch housing, all the blades 3 of the clutch heat dissipation structure provided by the invention are centrifugal blades, so that air on one side of the first housing 5 is sucked from the centers of all the centrifugal blades and then is discharged from the radial outer peripheries of all the centrifugal blades, axial air inlet and radial air exhaust are realized, an air flow path in the clutch housing is prolonged, and the air flow rate in contact with the internal structure of the clutch housing is improved.

Corresponding to the structure, the outer edge of the baffle 4 is fixed with the inner wall of the cavity of the first shell 5, namely the inner wall of the cavity of the half clutch in a sealing way, and the center of the baffle is provided with a baffle hole for air to flow to the centrifugal blade. When air reaches all the centrifugal blades through the baffle 4, the air cannot flow from the periphery of the baffle 4 to be attached to the inner wall of the clutch cavity, and must flow to the centers of all the centrifugal blades along the baffle holes in the centers of the baffle 4 to restrict the air inlet direction, so that the axial air inlet effect and the air inlet amount of all the centrifugal blades are ensured.

In consideration of the specific shape and configuration of the existing clutch product, the clutch main body 11 and the clutch end cap 2 are in a solid of revolution structure, the clutch main body 11 and the clutch end cap 2 are centrally located compared to the clutch cavity inside the clutch housing, so that all the centrifugal blades are arranged around the center hole of the clutch end cap 2, and the baffle hole is coaxial with the center hole, and the air entering from the baffle hole is uniformly diffused to each centrifugal blade and is uniformly diffused toward the radial direction of the clutch end cap 2 under the urging of all the centrifugal blades.

For a clutch end cap 2 having a center that is not coplanar with the outer periphery, all of the centrifugal blades may be fixed by the annular surface 12 of the outer periphery of the clutch end cap 2, and any of the centrifugal blades may be drawn toward the center of the clutch end cap 2 along the outer edge of the clutch end cap 2.

The inclination angle of any one centrifugal blade relative to the clutch end face can be adjusted according to the overall structure and the size of the clutch. It should be noted that the angle of inclination here includes an angle between any centrifugal blade and a diameter of the clutch end cap 2 at a position thereof, and also includes an angle between a plane of the centrifugal blade and a plane of the clutch end cap 2.

For better technical effect, the centrifugal blades are detachably fixed to the annular face 12 of the clutch end face by means of the blade mounting block 8. Specifically, a plurality of centrifugal blades can be arranged on one blade mounting block 8, the blade mounting block 8 is provided with a second mounting hole 9 and a fastener 10, a ring surface 12 is provided with a plurality of uniformly distributed first mounting holes 13, an installer aligns the second mounting hole 9 with the first mounting hole 13 according to the preset position of the centrifugal blades on the ring surface 12, and then the first mounting hole 13 and the second mounting hole 9 are locked through the fastener 10, so that the blade mounting block 8 and the ring surface 12 are fixed. Since the position of the blade mounting block 8 relative to the annulus 12 is adjustable, the spacing between all of the centrifugal blades is adjustable.

The centrifugal blades may be welded to the blade mounting block 8 or cast as one piece, and may be removably attached to the ring surface 12 in accordance with the attachment of the blade mounting block 8 to the ring surface. Illustratively, one surface of any blade mounting block 8, which is far away from the clutch end cover 2, is provided with a plurality of mounting grooves, one mounting groove can be used for inserting and fixing a centrifugal blade, the number of the centrifugal blades of one blade mounting block 8 and the distance between the centrifugal blades can be flexibly adjusted, and the centrifugal blades can be quickly replaced and maintained.

In addition to the above-mentioned embodiments, the blade mounting blocks 8 are disposed in a fan-shaped ring shape, and the radius of curvature is equal to the radius of the clutch end cap 2, and a plurality of the blade mounting blocks 8 may surround the clutch end cap 2 at intervals, or surround a ring structure having a size equal to the ring surface 12 in an uninterrupted manner.

In addition, the diameter of the baffle hole of the clutch heat dissipation structure provided by the invention is in any value between the inner diameter of the area enclosed by all the centrifugal blades and the diameter of the central hole of the clutch end cover 2, in other words, the diameter of the baffle hole is not too large and is smaller than the diameter of the area enclosed by the inner side edges of all the centrifugal blades, so that the turbulence prevention effect of the baffle 4 is avoided being influenced; also, the diameter of the baffle hole should not be too small, larger than the diameter of the center hole of the clutch cover 2, so as not to restrict the air flow.

In order to improve the cooling effect, the first shell 5 of the clutch heat dissipation structure provided by the invention is provided with the air inlet channel 6, the second shell 1 is provided with the air outlet channel 7, and when the first shell 5 and the second shell 1 are assembled oppositely, the air inlet channel 6 and the air outlet channel 7 are respectively arranged at two radial sides of the assembled clutch shell.
