Description
Technical field
The invention relates to a kind of motor configuration, especially a kind of motor configuration of being improved at the assembling and the locate mode of stator pack and bearing.
Background technology
Please refer to shown in Figure 1ly, existing motor configuration comprises a shell block 70, a rotor 80 and stator group 90.These shell block 70 central authorities have a hollow axle tube 71, and these central siphon 71 inside can be for inserting as members such as bearing 72, clasp 73, friction plate 74 and oil seal covers 75; These rotor 80 central authorities have a rotation axis 81, and this rotation axis 81 is rotatable in conjunction with this bearing 72; This stator pack 90 is to be installed in this central siphon 71 periphery walls.By this, this shell block 70, rotor 80 and stator pack 90 can be assembled mutually to constitute a motor configuration.
The stator pack 90 of existing motor configuration is fixed in the periphery wall of this central siphon 71 usually, this stator pack 90 by insulating case 91 on insulating case 92 double team silicon steel sheets 93 once and be wound with a wire coil 94 and constituted.Again, insulating case 91 is provided with a pressure section 911 in addition on this, and this pressure section 911 can be designed to several and compress sheet or be convex hoop shape, but makes this this bearing 72 of pressure section 911 crimping, gets loose to prevent this bearing 72.
Yet, existing motor configuration in the process of this stator pack 90 of assembling, the positioning action when this central siphon 71 can not provide these stator pack 90 assemblings, thereby cause definitely 9 one of this stator pack of standard assembling position accurately, so cause following shortcoming easily:
1, when the position that this stator pack 90 is assembled is too high, easily produce improper noise: as shown in Figure 1, existing motor configuration is an assembling convenience of guaranteeing this bearing 72, and avoid this central siphon 71 to be subjected to the extruding of this bearing 72 and be out of shape, this bearing 72 adopts the loose fit with minim gap between the two with this central siphon 71, therefore when the assembling position of this stator pack 90 is too high, though this bearing 72 is unlikely to deviate from, the pressure section 911 that should go up insulating case 91 also can't push against this bearing 72 and be fixed in the precalculated position, make this bearing 72 be difficult for being positioned really this central siphon 71 inside, when causing existing motor configuration to turn round, can produce noise because of the common shake of this bearing 72 and other associated components.
2, when the position that this stator pack 90 is assembled is too low, easily cause this pressure section that should go up insulating case 91 911 fractures: as shown in Figure 2, in the time of should going up pressure section 911 these bearings 72 of crimping of insulating case 91, the suitable strain that is utilization itself compresses this bearing 72, to prevent that this bearing 72 from getting loose or deviate from, yet when the position that this stator pack 9 is assembled is too low, then force the deflection of this pressure section 911 to increase easily, and then may exceed this pressure section 911 maximum deflections that allow own, cause this pressure section 911 to produce the fracture situations.
Summary of the invention
For solving above-mentioned shortcoming, main purpose of the present invention provides a kind of motor configuration, and it is provided with the joint portion location of a location division for stator group by a central siphon outer peripheral face, makes that the present invention has the effect of lifting positioning combination effect and assembling convenience.
Another object of the present invention provides a kind of motor configuration, and it is to form a ringwall by this stator pack, has the protection wall of barriers function with formation, makes the present invention have the dustproof effect.
According to motor configuration of the present invention, it comprises a shell block, a rotor and stator group.This shell block is provided with a central siphon, insert a bearing in this central siphon, and the outer peripheral face of this central siphon is provided with a location division; This rotor is rotatable in conjunction with this bearing; This stator pack has an assembly hole to be sheathed on the periphery wall of this central siphon, this stator pack is by insulating case on one and insulating case double team silicon steel sheet and twine a wire coil and constituted once, wherein should go up insulating case and have a pressure section, this time insulating case has a joint portion, the joint portion of this time insulating case is positioned the location division of this central siphon, gets loose preventing for this bearing of the certain crimping of this pressure section.
Motor configuration of the present invention is by the structural design of this location division, make this stator pack be sheathed on the outer peripheral face of this central siphon after, the joint portion of this stator pack can be blocked just to set and is positioned at this location division, and makes simultaneously suitable this bearing of crimping of pressure section of insulating case this on; Wherein this location division is arranged at the outer peripheral face appropriate location of this central siphon according to the predetermined assembling position of this stator pack, definite standard the accurate assembling position of this stator pack, and then the assembling position that can avoid this stator pack is too high and cause this bearing loosening, perhaps also can avoid the assembling position of this stator pack to cross low and cause this pressure section fracture, by this, can effectively promote the positioning combination effect and the assembling convenience of this stator pack.
