Description
Technical Field
The utility model relates to an automobile parts technical field, concretely relates to seal structure for motor housing.
Background
The motor shell is an important component for protecting the motor, and the sealing piece for the motor shell has stable and reliable sealing function. For the motor shell with a large specification, a rubber sealing piece with a large specification needs to be adopted, and the large-specification sealing ring is assembled in the motor shell and has the defects of low assembling efficiency, insecure assembling and the like, so that the subsequent capacity can be influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a seal structure for motor housing of assembly is simple, stable in structure. The technical scheme of the utility model is that: the utility model provides a seal structure for motor casing, motor casing's tip is equipped with the assembly section, and one side of assembly section is equipped with outstanding butt joint portion outwards, and butt joint portion department is equipped with the butt joint groove, and the assembly section is equipped with first annular and second annular to the indent, and first annular and second annular are distributed by being the echelonment, and first annular is used for placing first sealing washer, and the second annular is used for placing the second sealing washer.
According to a further technical scheme, the side wall of the second ring groove is a circular arc-shaped guide surface, and the circular arc-shaped guide surface is inwards concave. In a further technical scheme, a splicing column is arranged in the butt joint groove.
According to the technical scheme, a plurality of fixing holes are formed in the end face of the assembling section, and heat dissipation grooves are formed in the side wall of the motor shell corresponding to the fixing holes.
The utility model has the advantages that:
the utility model discloses a sectional type sealing washer is sealed, decomposes into two little sealing washers with big specification sealing washer, can guarantee not produce radial rotation after the installation of motor casing gomphosis to the butt joint groove, avoids setting up the sealing washer in first annular, second annular to receive radial rotation to produce the extrusion, guarantees that seal structure's assembly is more firm.
Drawings
FIG. 1 is a schematic structural view of the present invention,
the motor comprises a motor shell 1, a motor shell 2, an assembling section 3, a butt joint part 4, a butt joint groove 5, a plug column 6, a first ring groove 7, a second ring groove 8, an arc-shaped guide surface 9, a fixing hole 10 and a heat dissipation groove.
Detailed Description
The invention will be further elucidated below by means of non-limiting examples, understanding the invention.
As shown in fig. 1, the utility model provides a seal structure for motor casing, motor casing 1's tip be equipped with be used for with the assembly section 2 of casing lid assembly, one side of assembly section 2 outwards is equipped with outstanding butt joint portion 3, butt joint portion 3 department is equipped with butt joint groove 4, is provided with grafting post 5 in the butt joint groove 4. The assembly section 2 is inwards provided with a first annular groove 6 and a second annular groove 7 in an inwards concave mode, the first annular groove 6 and the second annular groove 7 are distributed in a step shape, the first annular groove 6 is used for placing a first sealing ring, and the second annular groove 7 is used for placing a second sealing ring. In order to facilitate the installation of the sealing ring arranged inside the motor housing 1, the side wall of the second annular groove 7 is a circular arc-shaped guide surface 8, and the circular arc-shaped guide surface 8 is inwards recessed. The second sealing ring is used for being attached to the end face of the connecting portion of the shell cover and forming static seal with the second sealing ring, and the first sealing ring is used for being sleeved on the outer wall of the connecting portion of the shell cover.
Be provided with a plurality of fixed orifices 9 on the terminal surface of assembly section 2, in order to strengthen large-scale motor casing 1's radiating effect, be provided with heat dissipation recess 10 on the lateral wall of motor casing corresponding fixed orifices 9 position.
The butt joint groove 4 can ensure that the motor shell 1 is not radially rotated after being embedded and installed, the sealing rings arranged in the first annular groove 6 and the second annular groove 7 are prevented from being extruded by radial rotation, and the assembly of the sealing structure is more firm.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
