In in mounting groove, bottom end cover screw thread is installed in stepped hole and against the bearing block；
The mounting groove is excessively connected with the stepped hole by the pyramidal structure of flaring from top to bottom, outside the bearing block
Wall sets the correspondence pyramidal structure upper end and is provided with rectangle bayonet socket.
Further, it is provided with rubber sheet gasket between the bearing block and the mounting groove.
Further, the bearing block includes outer sleeve, inner sleeve and extends internally from inner sleeve upper end open
Annular flange, the outer sleeve is sheathed on the inner sleeve and is threadedly coupled with the inner sleeve, the periphery of the inner sleeve
Face is provided with the perforation of filling slot and connection filling slot and installation cavity, on the inner sleeve inner peripheral surface and annular flange lower surface
The insulating barrier is provided with, the insulating barrier is formed with the filling part and connecting portion coordinated with the filling slot, perforation.
Further, the perforation is respectively arranged at two ends with bellmouth tapered from outside to inside, and the height of the bellmouth is
/ 2nd of perforation height.
Further, locating slot is provided with the top of the mounting groove, the upper surface of the annular flange is provided with and institute
State the upper positioning convex of locating slot cooperation；
The upper surface of the bottom end cover is provided with the lower positioning convex of ring-type, and the lower surface of the inner sleeve is provided with
The lower locating slot that positioning convex coordinates, the lower positioning convex, the cross section of lower locating slot are taper.
End cover for motor of the present utility model, is provided with mounting groove in lid, mounting groove openend is provided with stepped hole, bearing block
It is arranged in mounting groove, bottom end cover screw thread is installed in stepped hole and against bearing block, mounting groove and stepped hole are by from upper
The pyramidal structure of lower flaring is excessively connected, and bearing block outer wall sets correspondence pyramidal structure upper end and is provided with rectangle bayonet socket, de- in insulating barrier
Fall behind, only need to open bottom end cover, it is intraoral that from pyramidal structure instrument stretched into rectangular card, and bearing block is prized, and changing bearing block is
Can, reduce replacement cost；The setting of inner sleeve, outer sleeve, it is to avoid filling part is directly combined with the cavity of lid, is easy to take
Go out.
