Description

Technical Field

[0001] This utility model relates to the field of flywheel technology, specifically a flywheel. Background Technology

[0002] A flywheel, a disc-shaped component with a large moment of inertia, functions like an energy storage device. In a four-stroke engine, power is done only once every four piston strokes; the exhaust, intake, and compression strokes all consume power. Therefore, the torque output by the crankshaft varies periodically, and the crankshaft speed is unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft.

[0003] For example, the Chinese authorized patent, with publication number CN222596660U, entitled "(A Flywheel Structure)," includes: a flywheel body, which is generally circular in structure. The flywheel body has grooves for mounting, a connecting shaft, and mounting through holes. A flywheel gear ring is mounted on the outer wall of the flywheel body. Multiple external blades and multiple heat dissipation fins are fixedly connected to the side wall of the flywheel body. In this invention, the external blades increase the cooling airflow without placing a significant operational burden on the flywheel body. Furthermore, the combination of the external blades and the ring-shaped heat dissipation fins creates multiple airflow channels, promoting air circulation and improving the heat dissipation effect of the flywheel body. This avoids affecting the performance and reliability of the transmission system. The combination of the heat dissipation channels and the heat dissipation columns further accelerates heat dissipation from the side wall of the flywheel body, also serving as an auxiliary cooling mechanism.

[0004] However, existing flywheels cannot efficiently align and assemble with the external cover during installation, thus failing to meet current requirements. Therefore, we propose a new flywheel design. Utility Model Content

[0005] The purpose of this utility model is to provide a flywheel to solve the problem mentioned in the background art that the existing flywheel cannot be efficiently aligned and assembled with the external cover during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a flywheel, comprising: a flywheel body, an upper mounting cover being provided above the flywheel body, and a lower mounting cover being provided below the flywheel body;

[0007] Also includes:

[0008] A plurality of protruding ball heads are installed on the upper and lower ends of the flywheel body. The protruding ball heads are evenly distributed on the upper and lower ends of the flywheel body and are welded to both ends. The lower end of the upper mounting cover is provided with a first O-groove, and the interior of the first O-groove is provided with a first recessed groove. There are four first recessed grooves, and the four first recessed grooves and the first O-groove are integrally formed with the upper mounting cover. The upper end of the lower mounting cover is provided with a second O-groove, and the second O-groove and the second recessed groove are integrally formed with the lower mounting cover.

[0009] Preferably, an inner connecting mechanism is provided at the middle position inside the upper mounting cover, and the inner wall of the inner connecting mechanism is provided with a groove and a protrusion, and the groove and the protrusion are integrally formed.

[0010] Preferably, the inner side of the first O-groove is provided with a fourth reserved mounting hole and a fifth reserved mounting hole, and the fourth reserved mounting hole and the fifth reserved mounting hole are integrally formed with the lower end face of the upper mounting cover.

[0011] Preferably, a sixth reserved mounting hole is provided on the inner side of the second O-groove, and a plurality of sixth reserved mounting holes are provided. A seventh reserved mounting hole is provided on the inner side of the plurality of sixth reserved mounting holes, and a plurality of seventh reserved mounting holes are provided.

[0012] Preferably, a hollow cavity is provided at the middle position inside the flywheel body, and a second reserved mounting hole is provided on the outer side of the hollow cavity. Several second reserved mounting holes are provided, and a third reserved mounting hole is provided on the outer side of several second reserved mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the protruding ball heads provided on the upper and lower end faces of the flywheel body, and the first O-ring groove and first inner groove and second O-ring groove and second inner groove respectively provided on the upper and lower mounting covers, allows the protruding ball heads to be positioned inside the first O-ring groove and second O-ring groove when the upper and lower mounting covers clamp and fix the flywheel body. By rotating the flywheel body, the protruding ball heads are quickly and relatively fixed in position inside the first inner groove and second inner groove, thereby effectively avoiding the problem of inefficient alignment and assembly of the flywheel and the external cover during the installation process of existing flywheels.
