Background

The starting flywheel of a gasoline engine is usually arranged at one end of a crankshaft and has the functions of starting the engine for ignition and inertial resetting. A gear ring is required to be in interference fit with the outer circumference of a flywheel disc of an existing electric starting flywheel, the gear ring is meshed with a gear on a shaft of a starting motor, the flywheel disc is driven to rotate by the power of the starting motor, and therefore a crankshaft is driven to rotate to start an engine. The inner wall of the flywheel is fixed with magnetic steel, and after the magnetic steel is fixed on the inner wall of the flywheel, the magnetic steel fixed on the flywheel needs to be magnetized by a magnetizer. The existing specific operation modes for processing and magnetizing the flywheel are as follows: the flywheel body is integrally processed and molded through processing modes such as casting and the like, then the magnetic steel is adhered and fixed on the inner wall of the flywheel body by using an adhesive, after the adhesive is dried and solidified, a worker places the flywheel at a position corresponding to the magnetizing machine, the magnetizing machine magnetizes the flywheel, and then the worker takes away the magnetized flywheel. And after the magnetization is finished, finally, the gear ring is fixedly arranged on the flywheel. The existing flywheel is low in production efficiency because the magnetic steel is fixed on the flywheel in a sticking mode and needs to wait for the solidification of an adhesive before magnetizing the flywheel. And because the flywheel is provided with the shaft sleeve protruding out of the bottom surface of the flywheel, the flywheel is difficult to feed in a mode of automatically pushing the flywheel by laminating the flywheels and utilizing the automatic pushing devices one by one, manual feeding of workers is needed, the labor intensity of the workers is increased, and the production efficiency is reduced.
