In order to solve the technical problems in the prior art, as shown in fig. 3 and 4, the present embodiment provides a heat dissipation structure for a flywheel and a friction plate, the heat dissipation structure includes a flywheel 1 and a friction plate 2 capable of rotating relatively, the flywheel 1 is mounted at an output end of a crankshaft of an engine, and is used for storing energy of the engine, overcoming resistance of other components, and enabling the crankshaft to rotate uniformly. The friction plate 2 is arranged on one side of the flywheel 1. The flywheel 1 is provided with a first inclined hole 11, and the first inclined hole 11 gradually inclines towards the direction far away from the central axis of the flywheel 1 along the axial direction of the flywheel 1 and the direction far away from the friction plate 2. That is, as shown in fig. 4, the first inclined hole 11 is gradually inclined downward from right to left along the center axis of the flywheel. The friction plate 2 is provided with heat dissipation holes, and the first inclined holes 11 and the heat dissipation holes are discontinuously superposed in the relative rotation process of the flywheel 1 and the friction plate 2.
In the rotation process of the flywheel 1, the first inclined hole 11 is formed in the flywheel 1, and the heat of the flywheel 1 and the heat of the friction plate 2 are dissipated by using centrifugal force generated by rotation, so that the temperatures of the flywheel 1 and the friction plate 2 are reduced. Meanwhile, as the friction plate 2 is also provided with the heat dissipation holes, the heat dissipation holes and the first inclined holes 11 are discontinuously superposed and communicated in the relative rotation process of the flywheel 1 and the friction plate 2 to form an airflow channel. Due to the centrifugal force generated by the rotation of the flywheel, the airflow is accelerated to flow between the first inclined holes 11 and the heat dissipation holes, and the surface cooling of the flywheel 1 and the friction plate 2 is further accelerated.
Specifically, the flywheel 1 includes a flywheel body 13 and a flywheel flange 14 disposed on the flywheel body 13, the first inclined hole 11 is disposed on the flywheel body 13, and the friction plate 2 is disposed on a side close to the flywheel flange 14. During the relative rotation process of the flywheel 1 and the friction plate 2, most of airflow moves along the central axis direction of the flywheel 1 and the friction plate 2, the flywheel body 13 is provided with the first inclined hole 11, and under the action of the centrifugal force of the flywheel 1, the airflow more conforms to the first inclined hole 11 to flow, so that the flow of the airflow is accelerated.
More specifically, the first inclined holes 11 are circumferentially evenly distributed around the central axis of the flywheel body 13. Under the action of centrifugal force generated by rotation of the flywheel 1, airflow is driven to flow, and in order to enable the generated airflow to be more uniform, the heat dissipation effect is more uniform.
In order to further increase the heat dissipation speed of the flywheel 1 and reduce the weight of the flywheel 1, a through hole 12 is formed in the flywheel flange 14, and the central axis of the through hole 12 is arranged along the radial direction of the flywheel 1.
The heat dissipation holes on the friction plate 2 are straight holes 21 or second inclined holes.
The heat dissipation holes in this embodiment are through holes 21, and when the through holes 21 and the first inclined holes 11 on the flywheel 1 are discontinuously overlapped in the rotation process, airflow flows from the through holes 21 to the first inclined holes 11, and heat is taken away in the airflow flowing process.
When the heat dissipation holes are second inclined holes, the central axis of the first inclined hole 11 of the flywheel 1 and the central axis of the second inclined hole of the friction plate 2 can be overlapped. In the relative rotation process of the flywheel 1 and the friction plate 2, the central axes of the first inclined hole 11 and the second inclined hole are overlapped, so that the flow resistance of air flow is reduced, and the cooling speed is increased.
More specifically, the heat dissipation holes are circumferentially and uniformly distributed on the friction plate 2. When the flywheel 1 rotates, the centrifugal force is utilized to drive the airflow to flow, so that the airflow passing through the heat dissipation holes of the friction plate 2 is uniform, and the heat dissipation effect is more uniform.
When one of the friction plate 2 or the flywheel 1 breaks down, the friction plate 2 is provided with the heat dissipation holes, the flywheel 1 is provided with the first inclined holes 11, airflow convection can still exist between the friction plate 2 and the flywheel 1, and the friction plate 2 and the flywheel 1 are cooled down through heat dissipation.
The utility model discloses in still provide an engine, including the heat radiation structure of foretell flywheel and friction disc.
