Abstract
The invention provides a combined flywheel with eccentric mass. The combined flywheel comprises an integrally formed flywheel main body. The flywheel main body comprises a rotor mounting ring, a spokeplate and a flange plate. The spoke plate is arranged on one side of the rotor mounting ring. The flange plate is arranged at the center of the spoke plate. A plurality of signal teeth are arranged on the outer circumferential surface of the rotor mounting ring. The flange plate is of a hollow cylindrical structure. A plurality of through hole are formed in the flange plate, the spoke plate is composed of an eccentric area and a de-weight area, and a plurality of de-weight holes are uniformly formed in the de-weight area. By the adoption of the combined flywheel with the eccentric mass, the rotating speed can be stabilized, the first-order reciprocating inertia moment is balanced, the operation balance performance of a diesel engine is improved, and the functions of generating power and exhausting the air and cooling a generator stator are achieved, so that the service life of the diesel engine is prolonged, the weight of the diesel engine is reduced, and the power-to-weight ratio isincreased.
Description
technical field [0001] The invention belongs to the field of internal combustion engines, and in particular relates to a combined flywheel with eccentric mass. Background technique [0002] At present, the three-cylinder engine has an unbalanced rotational moment of inertia and first-order reciprocating moment of inertia due to structural limitations. The balance weight close to the crankshaft cannot meet the balance requirements, and the eccentric mass provided by the flywheel and the pulley is needed to help balance. Moreover, a generator is generally installed for starting, which increases the weight and cost of the internal combustion engine, and the structure is complicated. Contents of the invention [0003] In view of this, the present invention aims to propose a combined flywheel with eccentric mass to solve the problem of unbalanced moment balance of the three-cylinder engine and the problems of heavy weight, high cost and complex structure of the generator.
