Small high-speed ultra-silence generator set

Abstract

The invention discloses a small high-speed ultra-silence generator set. An engine assembly and a generator assembly are included and integrally designed. The engine assembly comprises a bent axle box,an air cylinder body, a cylinder head and an oil supply system. A stator of the generator assembly is fixed to an inner cavity of a right box, and a rotor of the generator assembly is installed at the output end of a bent axle. The advanced technologies such as electronic injection, water cooling, micro pressurizing, cam top arrangement, rocker rolling and pressure reducing self-starting are adopted in the small high-speed ultra-silence generator set. The integral structure of the generator set is greatly broken through, double cooling (water cooling and air cooling), double oil supply selection (electronic injection or a carburetor), double sound isolation (an inner cover and an outer shell), a duplex multi-cavity silencer, dual starting (hand pulling or electric starting), a dual-function air filter, a multipurpose structure (an ultra-silence generator becomes an integral direct current generator or electric vehicle range extender after the outer shell is removed) and the like are included. The generator set small in size, small in weight and high in efficiency is provided.

Description

technical field [0001] The invention relates to a small mobile backup power supply, in particular to a small high-speed ultra-quiet generating set. Background technique [0002] Most of the direct-connected gasoline generators currently on the market are excitation-type automatic voltage-regulating generators, equipped with general power, with a constant speed of 3000 rpm, and large volume and weight. 20 years ago, Japan's Honda Company launched a permanent magnet inverter generator set, which has decreased in size and weight, but still uses conventional general power, which cannot meet the requirements. [0003] However, in the prior art, in order to reduce the weight and miniaturization of the mobile power supply, it is necessary to increase the rotation speed of the generator set, but the high speed will cause a series of disadvantages such as poor heat dissipation, high temperature, fast wear, many faults, and large noise and vibration. .
