The bottom of motor casing is fastened by bolts in collar again, is installed simply, conveniently；And avoid head and the motor of screw
Shell outer wall is directly contradicted so that motor casing is under the hard force extruding of bolt, and motor casing produces certain deformation, so that in certain journey
The sealing effectiveness between bottom and motor casing is improved on degree.
It is preferred that, the bolt is provided with three, and three bolt equidistantly distributeds are on bottom.
By above-mentioned technical proposal, the mode of three bolt equidistantly distributeds is completed most with the bolt quantity of minimum number
Excellent fixed effect.
It is preferred that, the surface of the collar is provided with the shoulder block contradicted with jump ring inner circle.
By above-mentioned technical proposal, jump ring is pressed into the motor casing, mounting groove is entered until jump ring opens to be fitted together to
When middle, shoulder block will be contradicted in the inner circle of jump ring, and the setting of shoulder block can prevent jump ring from being taken off from mounting groove to a certain extent
Fall.
It is preferred that, the bottom is provided with the plug chimeric with the bottom of motor casing, and the outer wall of the plug is provided with the
Along provided with second staged corresponding with the first staged annular groove in one staged annular groove, the bottom of the motor casing
Rubber ring is mounted on the contact surface of annular groove, the first staged annular groove and the second staged annular groove.
By above-mentioned technical proposal, conflict is sealed layer by layer by the first staged annular groove and the second staged annular groove and is existed
Together, and on the excircle contact surface of the first staged annular groove and the second staged annular groove rubber ring is provided with, it is close layer by layer
Under envelope, good sealing effect.
It is preferred that, the first staged annular groove includes the first ladder, the second ladder successively by outer ring to inner ring, described
The height of first ladder is less than the height of the second ladder.
Pass through above-mentioned technical proposal, when plug is chimeric with motor casing bottom, the first ladder, the second ladder and the second ladder
Ladder is fitted together to formula annular groove layer by layer, it is ensured that the connection sealing between electric machine casing bottom and plug, the height of the first ladder
Less than the height of the second ladder, facilitate plug and be plugged in opening, and make the second ladder and the second staged annular groove
Better tightness, provides for sealing and is further ensured that.
It is preferred that, the second staged annular groove is included the 3rd ladder, fourth order ladder by outer ring to inner ring successively, described
The tread width of 3rd ladder is more than the tread width of fourth order ladder.
By above-mentioned technical proposal, when the first ladder is with the 3rd ladder, the second ladder and corresponding chimeric fourth order ladder, the
The tread width of three ladders is wider, makes the tread contact area of the 3rd ladder and the first ladder bigger, further enhances sealing
Effect.
In summary, the utility model having the beneficial effect that in contrast to prior art：
When bottom is arranged on into the bottom of motor casing, first collar is nested into the motor casing, then jump ring is pressed into this
In motor casing, jump ring opens inlay card and entered in mounting groove, and is strutted in mounting groove, by jump ring and ring-shaped step to axle
Ring is axially trapped, and reaches collar purpose fixed in motor casing.
