Sealing ring and sealing ring, offer first circular groove coaxial with axis hole on the rear end face of front motor cover, machine shaft passes through
Bearing in the first circular groove is rotated with front motor cover and is connected, and is offered and the first circle on the rear end face of front motor cover
The coaxial first annular groove of connected in star, offer on electric machine casing with first annular groove just to the second annular groove, it is close
Seal is inlaid in the cavity surrounded by first annular groove and the second annular groove, offer on the front end face of front motor cover with
The second circular groove that axis hole is coaxially disposed, sealing ring are inlaid in front motor cover is close with machine shaft in the second circular groove
Envelope, front motor cover rear end face edge offer respectively two just to wedge-shaped impression, the sophisticated phase of described two wedge-shaped impressions
To arranging, one end relative with tip of wedge-shaped impression is extended on the outside of front motor cover.
Further, the sealing ring is band neck sealing ring, offers the along its circumference on the cervical region lateral wall of sealing ring
Three annular grooves, are provided with flexible collar in the 3rd annular groove and sealing ring are clamped on machine shaft.
This utility model by sealing ring is set up between electric machine casing and front motor cover, in machine shaft and front motor cover
Between set up sealing ring so that front motor cover assembling after electric machine casing can be effectively sealed, so as to prevent the external world
Steam, dust are entered inside electric machine casing, prevent motor internal from making moist short circuit, extend motor service life；After front motor cover
End face is provided with two relative wedge-shaped impressions, when needing to dismantle front motor cover, first unloads bolt, reuses two wedges
Coordinate in two wedge-shaped impressions of insertion, the lower end plane of wedge is resisted against on electric machine casing, the upper end inclined-plane of wedge is supported
Lean against on the inclined-plane of wedge-shaped slot, firmly move wedge, you can front motor cover is levered up, it is so as to unload front motor cover, and direct
Extract front motor cover to compare, more laborsaving convenience.
