Two permanent magnetism power frequency no-brush synchronous generator rear cover assemblies
Technical field
The utility model relates to a kind of pair of permanent magnetism power frequency no-brush synchronous generator rear cover assembly, belongs to technical field of generators.
Background technology
All seal between the protecgulum of existing generator and bonnet and the shell, cause relying on the fin heat radiation on the shell, radiating effect is relatively poor, makes generator overheating easily, influences the normal use of generator.
Summary of the invention
The purpose of the utility model is in order all to seal between the protecgulum that solves existing generator and bonnet and the shell; Cause to rely on the fin heat radiation on the shell; Radiating effect is relatively poor; Make generator overheating easily, influence the normal problem of using of generator, and then a kind of pair of permanent magnetism power frequency no-brush synchronous generator rear cover assembly is provided.
The purpose of the utility model realizes through following technical scheme:
The utility model comprises: cover and bonnet hood at the bottom of back cover, bonnet shutter, the bonnet; The left and right sides on the cover of said back has shutter; The downside of back cover has end cover mouth, has the hood mouth on the rear end face of back cover, and the shutter of back cover is provided with the bonnet shutter; The end cover mouth of back cover covers at the bottom of being provided with bonnet, and the hood mouth of back cover is provided with the bonnet hood.
Can find out by the above-mentioned technical scheme that provides; Shutter behind the utility model on the cover, end cover mouth and hood mouth all are used for ventilating; Ventilating good heat radiation could be good, so the good heat dissipation effect of the utility model, makes generator operate as normal for a long time.Can to prevent that foreign matter from getting into generator inner for cover and bonnet hood at the bottom of on shutter, end cover mouthful and the hood mouth bonnet shutter, bonnet being installed, and avoids generator to have an accident, and finger and other limbs that also can prevent the people get in the generator and cause danger.
