Cap assembly before two permanent magnetism power frequency no-brush synchronous generators
Technical field
The utility model relates to the preceding cap assembly of a kind of pair of permanent magnetism power frequency no-brush synchronous generator, 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 provide a kind of pair of permanent magnetism power frequency no-brush synchronous generator preceding cap assembly.
The purpose of the utility model realizes through following technical scheme:
The utility model comprises: cover at the bottom of preceding cover, protecgulum shutter and the protecgulum; The left and right sides before said on the cover has the avris ventilating opening; The downside of preceding cover has the bottom side ventilating opening; Avris ventilating opening on the preceding cover is provided with the protecgulum shutter, and the bottom side ventilating opening on the preceding cover covers at the bottom of being provided with protecgulum.
Can find out by the above-mentioned technical scheme that provides; Cover is provided with before the utility model avris ventilating opening and bottom side ventilating opening all are used for ventilating; And ventilation effect is 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 at the bottom of protecgulum shutter and protecgulum are installed on avris ventilating opening and the bottom side ventilating opening, avoids generator to have an accident, and it is interior and cause danger that finger and other limbs that also can prevent the people get into generator.

Embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment provided detailed execution mode, but the protection range of the utility model is not limited to following embodiment being to implement under the prerequisite with the utility model technical scheme.
Like Fig. 1~shown in Figure 5; The preceding cap assembly of a kind of pair of permanent magnetism power frequency no-brush synchronous generator that present embodiment is related; Cover 3 at the bottom of cover 1, protecgulum shutter 2 and the protecgulum before comprising, the left and right sides on the said preceding cover 1 has avris ventilating opening 7, and the downside of preceding cover 1 has bottom side ventilating opening 8; Avris ventilating opening 7 on the preceding cover 1 is provided with protecgulum shutter 2, and the bottom side ventilating opening 8 on the preceding cover 1 covers 3 at the bottom of being provided with protecgulum.
The rear wall of cover 1 is provided with bearing chamber 5 before said.
The edge of cover 1 is provided with circular flange dish 6 before said.
Said circular flange dish 6 inboard preceding covers 1 are provided with flange seam 4.
The material of said back cover 1 adopts steel Q235 or cast iron.
The above; Be merely the preferable embodiment of the utility model; These embodiments all are based on the different implementations under the utility model general idea, and the protection range of the utility model is not limited thereto, and any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range of claims.
