Abstract
The generator is composed of a rotor, a stator, a shell end cover, a fan and the like, wherein a stator magnetic pole is matched with a spigot of the end cover to be in direct contact with the spigot of the stator, the shell is totally enclosed, the fan is arranged outside the shell, and heat is completely dissipated by the shell.
Description
The utility model relates to a kind of alternating current generator, is the totally enclosed alternating current generator of a kind of shell.
In order to solve heat dissipation problem, all be to adopt air-cooled or two kinds of schemes of water-cooled on the generator designs, if adopt the forced air cooling design for the generator main on vehicle and the engineering machinery, be that the generator body two ends have ventilating opening, utilize the fan blade air blast to make wind pass through end cap, rotor, stator, formation convection current, heat in the generator is taken out of, though this radiating mode effect is relatively good, but air-flow in generator by the time bring a lot of dust and other foreign material into, electric winding insulation influence to generator is very big, is the main cause that generator burns.
The utility model is influence that solves dust and the heat dissipation problem that solves generator, proposed a kind of unique design, Power generator fan is located at outside the casing, casing adopts totally enclosed type, heat only distributes from casing, and this generator is applicable to working under any adverse circumstances.
Accompanying drawing of the present utility model and drawing explanation:
Fig. 1 is a main cutaway view of the present utility model;
Fig. 2 is an end view of the present utility model.
1---main shaft; 2---brush cover; 3---front end housing; 4---fan; 5---belt pulley; 6---the board-like pawl utmost point of rotor steel; 7---magnetic pole of the stator; 8---rotor coil; 9---stator coil;
The utility model is achieved in that drive end bearing bracket 3 and brush cover 2 are sealings The type lid, lid is provided with radiating ribs, two end cap cooperates with magnetic pole of the stator 7 seams, connect with bolt, not directly contact between the two end cap, magnetic pole of the stator 7-part contacts with extraneous air, and fan 4 and rotor coaxial are contained between drive end bearing bracket 3 and the belt pulley 5, the steel plate type pawl utmost point 6 that rotor adopts is punch formings, and pawl is staggered installation of in opposite directions.
Below in conjunction with embodiment the utility model is further described: the utility model has adopted hermetically sealed scheme, the electric heat that generator produces mainly is by heat conducting mode, lead in the air by magnetic pole of the stator and two end cap, main shaft transmission, the effect of fan is that the heat of accelerating electric machine casing is distributed, because some directly contacts magnetic pole of the stator with outside air, and two end cap promptly reaches whole end cap with the heat on the magnetic pole of the stator.End cover surface is provided with perpendicular muscle, comes down to have increased area of dissipation.So reached the purpose of dustproof, waterproof, good heat dissipation effect.
The utility model is structurally very compact, and the shell area of dissipation is big, is applicable to various vehicles, especially the engineering machinery of working under the serious bad working environments of dust pollution.
