Fig. 1 is a schematic structural diagram of a clutch heat dissipation structure according to an embodiment of the present invention; FIG. 2 is an enlarged schematic view of FIG. 1 at A; FIG. 3 is an exploded view of FIG. 1; FIG. 4 is a schematic diagram illustrating assembly of a clutch end cap, a vane, and a vane mounting block according to an embodiment of the present invention; FIG. 5 is a schematic view illustrating assembly of a clutch end cap, a vane, and a vane retaining block in another direction according to an embodiment of the present invention; fig. 6 is an assembly schematic diagram 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 being assembled into 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 of the clutch main body 11 close to the first shell 5; and 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 housing 5 and the second housing 1 are respectively provided with half clutch cavities, and the first housing 5 and the second housing 1 are spliced in opposite directions to form a complete clutch cavity. The clutch body 11 and the clutch end cap 2 are mounted in the clutch cavity, the clutch body 11 being adjacent the second housing 1 and the clutch end cap 2 being adjacent the first housing 5.
All the blades 3 are provided to the clutch end cap 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 housing 5 side and discharge the air to the second housing 1 side.
The baffle 4 is disposed between all the blades 3 and the first housing 5. The baffle 4 restricts the flow direction of air when the air is introduced from the first housing 5 into the vane 3 on the one hand, and prevents the reverse flow of air from being caused to the first housing 5 side after the air is discharged from the vane 3 on the other hand, thereby ensuring that the vane 3 forms a stable flow direction from the first housing 5 to the second housing 1 in the clutch housing, thereby improving the air flow rate and cooling effect in the clutch housing.
The clutch heat dissipation structure provided by the invention is further described below with reference to the accompanying drawings and embodiments.
In order to sufficiently cool the inside of the clutch housing, all the blades 3 of the clutch heat dissipation structure provided by the invention are provided as 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 discharged from the radial outer circumferences of all the centrifugal blades, and the axial air inlet and the radial air discharge are realized, so that the air flow path in the clutch housing is prolonged and the air flow in contact with the inside structure of the clutch housing is improved.
Corresponding to the above structure, the outer edge of the baffle plate 4 is sealed and fixed with the inner wall of the cavity of the first housing 5, namely, the half clutch cavity, and the center is provided with a baffle plate hole for air to flow to the centrifugal blades. When air reaches all centrifugal blades through the baffle plate 4, the air cannot flow from the periphery of the baffle plate 4 to the inner wall of the clutch cavity, and the air must flow to the centers of all centrifugal blades along the baffle plate holes in the centers of the baffle plate 4 to restrict the air inlet direction, so that the axial air inlet effect and the air inlet amount of all centrifugal blades are ensured.
Considering the specific shape configuration of the existing clutch product, the clutch body 11 and the clutch end cover 2 take on a solid of revolution structure, the clutch body 11 and the clutch end cover 2 are centered with respect to the clutch cavity inside the clutch housing, so that all centrifugal blades are disposed around the center hole of the clutch end cover 2, while the baffle holes are coaxial with the center hole, and air entering from the baffle holes is uniformly diffused to the respective centrifugal blades and is uniformly diffused toward the radial direction of the clutch end cover 2 under the pushing of all centrifugal blades.
For a clutch end cap 2 with a center that is not coplanar with the outer periphery, all centrifugal blades may also be fixed by the annulus 12 of the outer periphery of the clutch end cap 2, with either centrifugal blade converging toward the center of the clutch end cap 2 along the outer edge of the clutch end cap 2.
The inclination angle of any centrifugal blade relative to the end face of the clutch can be adjusted according to the integral structure of the clutch and the size of the clutch. It should be noted that, the inclination angle here includes an angle between any centrifugal blade and the diameter of the clutch end cover 2 at the position where the centrifugal blade is located, and also includes an angle between the plane where the centrifugal blade is located and the plane where the clutch end cover 2 is located.
For better technical effect, the centrifugal blades are detachably fixed to the annular surface 12 of the clutch end face through the blade mounting blocks 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, the annular surface 12 is provided with a plurality of first mounting holes 13 uniformly distributed, an installer aligns the second mounting holes 9 with the first mounting holes 13 according to the preset positions of the centrifugal blades on the annular surface 12, and the first mounting holes 13 and the second mounting holes 9 are locked through the fastener 10, so that the blade mounting block 8 and the annular surface 12 are fixed. Since the position of the blade mounting blocks 8 relative to the annulus 12 is adjustable, the spacing between all centrifugal blades is adjustable.
The centrifugal blade can be welded with the blade mounting block 8 into a whole, and can also be integrally formed by casting and the like, and in addition, the detachable connection can be realized according to the connection mode of the blade mounting block 8 and the annular surface 12. Illustratively, one side of any one of the blade mounting blocks 8 facing away from the clutch end cap 2 is provided with a plurality of mounting grooves, one mounting groove is used for inserting and fixing one centrifugal blade, the number of the centrifugal blades of one of the blade mounting blocks 8 and the distance between the centrifugal blades can be flexibly adjusted, and for any one centrifugal blade, quick replacement and maintenance can be realized.
On the basis of the above embodiment, the blade mounting blocks 8 are arranged in a fan-ring shape and have a radius of curvature equal to that of the clutch end cover 2, and the plurality of blade mounting blocks 8 can enclose the clutch end cover 2 in a spaced manner or can enclose a ring structure as large as 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 any value between the inner diameter of the area surrounded by all 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 excessively large, and is smaller than the diameter of the area surrounded by the inner edges of all centrifugal blades, so that the turbulence prevention effect of the baffle 4 is prevented from being influenced; also, the diameter of the baffle holes should not be too small, which is 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 housing 5 of the clutch heat dissipation structure provided by the invention is provided with the air inlet channel 6, the second housing 1 is provided with the air outlet channel 7, and when the first housing 5 and the second housing 1 are assembled in opposite directions, the air inlet channel 6 and the air outlet channel 7 are respectively arranged at two radial sides of the assembled clutch housing.
