Description

Technical Field

[0001] The utility model relates to the technical field of sealing structures for flywheels, in particular to a sealing structure for flywheels. Background Art

[0002] The disc-shaped parts with large rotational inertia act like an energy storage device. For a four-stroke engine, work is done once for every four piston strokes, that is, only the power stroke does work, while the exhaust, intake and compression strokes all consume work. Therefore, the torque output by the crankshaft changes periodically and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft.

[0003] At present, a Chinese patent with announcement number CN218787270U discloses a rotating sealing structure for a flywheel, including an inner core and a wheel disc. The outer surface of the inner core is fixedly connected with a plurality of annularly distributed jacks, the inner wall of the wheel disc is provided with inner teeth, the jacks are meshed with the inner teeth, the outer surface of the wheel disc is fixedly connected with a plurality of annularly distributed outer teeth, the left and right sides of the outer surface of the wheel disc are fixedly connected with sealing discs by fixing bolts. When in use, two groups of sealing discs are installed on the left and right sides of the outer surface of the wheel disc by fixing bolts. After the sealing disc is installed, the annular protrusion will be inserted into the corresponding annular sealing groove, and the annular protrusion will abut the annular gasket, thereby preventing dust from entering through the gap between the wheel disc and the sealing disc. The inner wall of the annular pressure ring is connected with a plurality of annular convex rings, which abut against the outer surface of the inner core, thereby preventing dust from entering through the gap between the inner core and the sealing disc, effectively avoiding the stability of the flywheel during rotation.

[0004] A sealing structure is mostly used during the installation of a flywheel, and the existing sealing structures for flywheels are mostly relatively simple, usually using a sealing ring for sealing. The sealing ring is prone to aging during long-term use, which can easily lead to impurities such as dust and sand entering the gap between the flywheel and related components, causing wear and failure. The overall performance and stability of the system where the flywheel is located are poor, making it inconvenient for users to use. Utility Model Content
