The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of effective elimination alignment error is provided, the mounting structure of the soya-bean milk cover of the perpendicularity of assurance motor shaft and mounting plane.
For achieving the above object, the technical solution of the utility model is: a kind of mounting structure of soya-bean milk cover, comprise head upper cover and the head lower cover that cooperatively interacts and be located at electric machine support on the head lower cover, be provided with the keeper of fixed electrical machinery support between this head lower cover and the electric machine support.
In this programme, motor is fixed on the electric machine support, electric machine support peripheral hardware keeper, head lower cover is installed the back clamping motor and is fixed, because between head lower cover and the electric machine support keeper is arranged, can realize the accurate location and installation of motor, effectively eliminate alignment error, guarantee the perpendicularity of motor shaft and mounting plane.
Further, this keeper is worker's type shape structure, and this electric machine support sticks in the groove of worker's type shape structure; This keeper is a silicagel pad.Because keeper adopts the silicagel pad of flexible material, makes the motor output shaft position can carry out self-control more neatly, guarantee the perpendicularity of motor shaft and mounting plane.
Further, also be arranged with the layer of metal lower cover under this head lower cover; This metal lower cover is the stainless steel lower cover.
Further, be provided with first seal between this head upper cover and the head lower cover, be provided with second seal between this head lower cover and the metal lower cover.
Further, this first, second seal is located at the junction of head upper cover and head lower cover, head lower cover and metal lower cover respectively, and is realized installing and fixing by the screw hole that screw is located at metal lower cover, second seal, head lower cover, first seal and head upper cover by correspondence.
Cover under head lower cover and the metal and be equipped with through hole, motor output shaft stretches out under the metal lower cover by two through hole, is set with a rigid seal between the through hole of this head lower cover and the motor output shaft; This rigid seal is formed for rigid disk is set in a flexible seals, rigid cage perhaps is set at the flexible seals two ends forms.This programme is by this rigid seal, the effective installation site of positioning motor output shaft, complete machine is when assembling, under the rigidity positioning action of this rigid seal, motor output shaft can accurately pass the through hole of motor lower cover and metal lower cover, to the damage of seal, in the service life that can effectively improve motor, improve motor lower cover and metal lower cover installation Aligning degree greatly when avoiding causing output shaft to rotate owing to the seal alignment error.
The through hole edge of this head lower cover extends a hollow tubular structure downwards, and this hollow tubular structure extends to metal lower cover through hole or below, is provided with the 3rd seal between this hollow tubular structure and the metal lower cover through hole.
In order further to improve the Aligning degree of metal lower cover and motor lower cover, the through hole edge of this motor lower cover extends a hollow tubular structure downwards, this hollow tubular structure extends to metal lower cover through hole or below, be provided with second seal between this hollow tubular structure and the metal lower cover through hole, during assembling, only the through hole of metal lower cover need be put or aims at hollow tubular structure can effectively realize aiming at, and by the second seal seal clearance, this scheme efficiently solve directly with the gap of seal sealed electric-motor output shaft and through hole the defective of issuable position error, improved whole aircraft reliability greatly.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model discloses a kind of mounting structure of soya-bean milk cover, comprise the head upper cover that cooperatively interacts 1 and head lower cover 2 and be located at electric machine support 3 on the head lower cover 2, be provided with the keeper 4 of fixed electrical machinery support 3 between this head lower cover 2 and the electric machine support 3.
During assembling, motor 13 is fixed on the electric machine support 3, electric machine support 3 overcoats are established keeper 4, and electric machine support 3 is fixed in the head lower cover 2, it is fixing by keeper 4 clamping motor supports 3 that head lower cover 2 is installed the back, because between head lower cover 2 and the electric machine support 3 keeper 4 is arranged, can realize the accurate location and installation of motor 13, effectively eliminate alignment error, guarantee the perpendicularity of motor shaft and mounting plane.
This keeper 4 is worker's type shape structure, and this electric machine support 3 sticks in the groove of worker's type shape structure; This keeper 4 is a silicagel pad.Because keeper 4 adopts the silicagel pad of flexible material, makes motor output shaft 9 positions can carry out self-control more neatly, guarantees the perpendicularity of motor output shaft 9 and mounting plane.
This head lower cover also is arranged with layer of metal lower cover 52 times; This metal lower cover 5 is the stainless steel lower cover.
As shown in Figure 4,, be provided with first seal 6 between this head upper cover 1 and the head lower cover 2, be provided with second seal 7 between this head lower cover 2 and the metal lower cover 5 in order to improve sealing.
This first, second seal 6,7 is located at the junction of head upper cover 1 and head lower cover 2, head lower cover 2 and metal lower cover 5 respectively, and is realized installing and fixing by the screw hole that screw 8 is located at metal lower cover 5, second seal 7, head lower cover 2, first seal 6 and head upper cover 1 by correspondence.
As shown in Figure 5, be equipped with through hole on head lower cover 2 and the metal lower cover 5, motor output shaft 9 stretches out the metal lower cover 5 times by two through hole, is set with a rigid seal 10 between the through hole of this head lower cover 2 and the motor output shaft 9.This rigid seal 10 is formed for rigid disk is set in a flexible seals, rigid cage perhaps is set at the flexible seals two ends forms.
During assembling, rigid seal 10 is sleeved on the motor output shaft 9, and be located between the through hole and motor output shaft 9 of head lower cover 2, conflict on the cylindrical inner wall of head lower cover 2 in these rigid seal 10 outsides, under the rigidity positioning action of this rigid seal 10, in the time of can avoiding causing motor output shaft 9 to rotate owing to the seal alignment error to the damage of seal.
The through hole edge of this head lower cover 2 extends a hollow tubular structure 11 downwards, and this hollow tubular structure 11 extends to metal lower cover 5 through holes or below, is provided with the 3rd seal 12 between this hollow tubular structure 11 and metal lower cover 5 through holes.
