AI Technical Summary

Technical Problem

The existing diesel flywheels are insufficiently applicable between different types and power diesel engines, resulting in the need to customize or replace the flywheels to increase the moment of inertia, which increases costs and labor and material consumption.

Method used

A marine high-power medium-speed diesel ball iron flywheel is designed, using counterweight components and installation components, allowing the inertia of the diesel engine to be adjusted without replacing the entire flywheel, and this is achieved by replacing counterweights of different mass or quantities.

Benefits of technology

It realizes simple adjustment of inertia on the existing flywheel, reducing costs and manpower and material consumption, while improving the applicability and flexibility of the flywheel.

Abstract

The utility model belongs to the technical field of diesel engine flywheels, and particularly discloses a marine high-power medium-speed diesel engine ductile iron flywheel which comprises a flywheel body, and a counterweight assembly is arranged in the flywheel body. Each group of counterweight assemblies comprises a counterweight block, a counterweight groove is formed in the flywheel body, the counterweight blocks are located in the counterweight groove, trapezoidal blocks are arranged at the two ends of each counterweight block, mounting assemblies are arranged at the two ends of each counterweight block, the number of the mounting assemblies is multiple, and each group of mounting assemblies comprises two springs. Due to the arrangement of the counterweight assembly, the counterweight blocks with different masses or numbers can be replaced according to requirements, the inertia of the diesel engine can be adjusted under the condition that the whole flywheel is not replaced, and compared with customized or replaced flywheels in the prior art, the inertia of the diesel engine can be adjusted, so that the inertia of the diesel engine can be adjusted. And by additionally arranging the counterweight, simple adjustment can be carried out on the existing flywheel, and the cost is reduced.
