Description

Generator casing
Technical field
The utility model relates to a kind of generator casing, especially relates to a kind of shell of permanent magnet generator.
Background technology
The principle of generator is closed conductor cutting magnetic induction line. consumes mechanical energy and obtained electric energy. and mainly be that kinetic energy is converted to electric energy, wherein the source of kinetic energy has multiple, for example, wind-force, waterpower or firepower etc., when the power of various kinetic energy is imported generator inside via line shaft, after the coil of the permanent magnet that can utilize each rotor of rotor set and the stator pack that is oppositely arranged interacts, can produce electric energy and export via lead.
The magnetic field of permanent magnet generator is produced by permanent magnet.Permanent magnet is magnetic source in motor, is again the part of magnetic circuit.The magnetic property of permanent magnet is not only relevant with the manufacturing process of factory, and also relevant with the capacity and the magnetization method of the shape and size of permanent magnet, magnet charger, the discreteness of specific performance data is very big.And magnetic flux and magnetomotive force that permanent magnet can provide in motor also change with material property, size and the motor operating state of magnetic circuit remainder.
The magnetic structure of permanent magnet generator is varied, the large percentage that leakage magnetic circuit is very complicated and leakage flux accounts for, and the ferromagnetic material part is more saturated than being easier to again, and magnetic conductance is non-linear.Especially in the permanent magnet generator of sandwich construction was made, because the magnetic force that permanent magnet forms exists, the phase place that has a strong impact on stator coil was determined, the mounting processs such as assembling of rotor.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of freshwater mussel formula structure generator casing is provided.The technical solution of the utility model is as follows:
A kind of shell of permanent magnet generator comprises housing and bearing 5, and described shell 1 is to be divided into upper shell 8, lower house 9 two-part freshwater mussel formula structures, and upper shell 8 is connected with bolt 6 with lower house 9.
Further preferred, describedly design a plurality of parallel mounting grooves 2, with the location stator in enclosure interior.Stator mounting groove quantity is determined according to design stator quantity.
Further preferred, be raised structures at described mounting groove 2.
The utility model can also be realized by following execution mode: further preferred, mounting groove can be the structure that falls in.Mounting groove has guaranteed the axial stability and the accuracy of stator.
Further preferred, the one or more phase place location notchs 7 of horizontally set in mounting groove 2 design corresponding falcon structure simultaneously on stator, and this location notch 7 will form groove falcon structure with stator.Like this, as long as the stator tenon is inserted in the location notch, just can accurately locate phase place during installation, guarantee the radial stability and the accuracy of stator simultaneously.
Further preferred, described mounting groove 2 height exceed to be no more than stator coil, and the degree of depth is exceeded not penetrate housing.
When if mounting groove 2 is groove shape structure, the degree of depth of mounting groove 2 is exceeded to be no more than stator coil.
Further preferred, described location notch 7 height exceed to be no more than mounting groove, and the degree of depth is exceeded with thickness of shell.Clamping slot depth, highly can be any, the height exceed to be no more than mounting groove, the degree of depth is exceeded with thickness of shell, promptly can penetrate housing.
The case material of the shell of permanent magnet generator described in the utility model is a nonmagnetic substance.
Further preferred, described nonmagnetic substance is stainless steel or aluminium.
The utility model when mounted, stator, bearing are individually fixed in corresponding mounting groove 2 and the flange (3).
For fixing better, described upper shell 8 is distributed with reinforcement 4 with lower house 9.
The utility model is its beneficial effect compared with prior art:
1, the shell of the utility model permanent magnet generator adopts, upper shell, the two-part freshwater mussel formula of lower house structure, and this is simple in structure;
2, the manufacture craft flow process of the generator casing of this freshwater mussel formula structure is simple;
3, rational in infrastructure;
4, the convenient installation.
