Inner balance flywheel

Abstract

The invention discloses an inner balance flywheel. The inner balance flywheel comprises a flywheel body, variable inertia sliding blocks and an inner balance rotating disc. The at least two variable inertia sliding blocks are evenly arranged around a rotating shaft of the flywheel body and connected to the flywheel body in a radial sliding mode, a synchronizer is the inner balance rotating disc which is connected with the flywheel body in a coaxial rotating mode, the inner balance rotating disc is in sliding fit with the variable inertia sliding blocks through a plane sliding way, the plane sliding way deflects in the circumferential direction of the rotating disc, and then a certain included angle is formed between the plane sliding way and the sliding direction of the corresponding sliding block. According to the inner balance flywheel, the rotational inertia of the inner balance flywheel can change within a certain range along with the change of the rotating speed of an engine, stability of the engine in the high-speed running process can be guaranteed, the rated rotating speed range of the engine can be widened, flexibility of frequent speed change of the engine is improved, the comprehensive usability of the engine is improved, and the requirement of social development can be met.

Description

technical field [0001] The invention relates to a flywheel, in particular to an inner balance flywheel. Background technique [0002] The flywheel is a wheel-shaped accumulator installed on the crankshaft of the engine with a large moment of inertia. When the engine speed increases, the kinetic energy of the flywheel increases to store energy; when the engine speed decreases, the kinetic energy of the flywheel decreases to release energy. It can be used to reduce the speed fluctuation of the mechanical operation process, and can store part of the energy of the engine's power stroke to overcome the resistance of other strokes and make the crankshaft rotate evenly. The greater the moment of inertia of the flywheel, the stronger its energy storage capacity , which is conducive to the smooth operation of the engine, but it needs to consume more energy to overcome the inertia energy of the flywheel during the start-up or shifting process, which reduces the flexibility of the engi...

[0002] The flywheel is a wheel-shaped accumulator installed on the crankshaft of the engine with a large moment of inertia. When the engine speed increases, the kinetic energy of the flywheel increases to store energy; when the engine speed decreases, the kinetic energy of the flywheel decreases to release energy. It can be used to reduce the speed fluctuation of the mechanical operation process, and can store part of the energy of the engine's power stroke to overcome the resistance of other strokes and make the crankshaft rotate evenly. The greater the moment of inertia of the flywheel, the stronger its energy storage capacity , which is conducive to the smooth operation of the engine, but it needs to consume more energy to overcome the inertia energy of the flywheel during the start-up or speed change process, which reduces the flexibility of the engine. In the prior art, the flywheel is generally a fixed disc structure, and its moment of inertia is fixed. The weight of the flywheel is usually selected, which cannot effectively ensure the stability of the high-speed operation of the engine, limits the range of the engine's rated speed, and also affects the flexibility of the engine's frequent speed changes, resulting in poor overall performance of the engine and cannot meet social development. needs
