Description
Technical field
This utility model is related to electric motors and in particular to a kind of Split type electrical cover.
Background technology
Existing motor cover offers bearing chamber in centre, and bearing chamber is used for installing bearing, but this motor cover
Lack the design of anti-shaft current, easily form shaft current between motor cover, bearing and rotating shaft, shaft current can have a strong impact on axle
Hold the service life with motor, there is potential safety hazard in use, reliability is relatively low.Some motor cover are in bearing chamber
Inwall on injection be formed with insulating barrier, to prevent the generation of shaft current, but after long-term use, insulating barrier is easy to fall off, need more
Change whole motor cover, replacement cost is higher.
Utility model content
For the problems referred to above, this utility model provides a kind of Split type electrical cover, and it can solve prior art axis
Hold room insulating barrier come off after need to change the technical problem of whole motor cover.
Its technical scheme is such, it include lid it is characterised in that：Described lid is the cylinder knot of both ends open
Structure, it also includes upper cover plate, bearing block and lower cover, and described upper cover plate is provided with upper logical with the shaft hole matching of described bearing block
Hole, described lower cover is provided with the lower through-hole with the installation cavity cooperation of described bearing block, described upper cover plate, lower cover screw thread respectively
It is installed on the cavity upper/lower terminal of described lid, described bearing block is press-fited by described upper cover plate, lower cover and is fixed on described lid
In the cavity of body；
Described bearing block includes outer sleeve, inner sleeve and the annular flange extending internally from inner sleeve upper end open,
Described outer sleeve is sheathed on described inner sleeve and is threadeded with described inner sleeve, and the outer peripheral face of described inner sleeve is provided with
Filling slot and the perforation of connection filling slot and installation cavity, described inner sleeve inner peripheral surface and annular flange lower surface are provided with insulation
Layer, described insulating barrier is formed with and described filling slot, the filling part of perforation cooperation and connecting portion.
Further, described perforation is respectively arranged at two ends with bellmouth tapered from outside to inside, and the height of described bellmouth is
/ 2nd of perforation height.
Further, the upper surface of described lower cover is provided with the positioning convex of ring-type, on the lower surface of described inner sleeve
It is provided with the locating slot with positioning convex cooperation, described positioning convex, the cross section of locating slot are taper.
Motor cover of the present utility model, screw thread is installed on the cavity upper/lower terminal of lid respectively for upper cover plate, lower cover,
Bearing block bearing seat is press-fited in the cavity being fixed on lid by upper cover plate, lower cover, after insulating barrier comes off, only need to open
Upper and lower end cap, bearing block is knocked out, and changes bearing block, reduces replacement cost；Inner sleeve, the setting of outer sleeve, it is to avoid
Filling part is directly combined with the cavity of lid, is easy to take out.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, it includes lid 1, lid 1 is the tube structure of both ends open, and it also includes upper cover plate 2, bearing
Seat and lower cover 4, upper cover plate 2 is provided with the upper through hole with axis hole 35 cooperation of bearing block, and lower cover 4 is provided with and bearing block
Installation cavity joins the lower through-hole of 36 conjunctions, and screw thread is installed on the cavity upper/lower terminal of lid 1, bearing block respectively for upper cover plate 2, lower cover 4
Press-fited in the cavity being fixed on lid 1 by upper cover plate 2, lower cover 4；
Bearing block includes outer sleeve 31, inner sleeve 37 and the annular flange extending internally from inner sleeve upper end open
38, outer sleeve 31 is sheathed on inner sleeve 37 and is threadeded with inner sleeve, and the outer peripheral face of inner sleeve 37 is provided with filling slot 33
And the perforation 34 of connection filling slot and installation cavity, inner sleeve 37 inner peripheral surface and annular flange 38 lower surface be provided with insulating barrier 5,
Insulating barrier 5 is formed with and filling slot, the filling part of perforation cooperation and connecting portion, and insulating barrier, filling part and connecting portion are injection one
Body formed.
Perforation is respectively arranged at two ends with bellmouth tapered from outside to inside, the height of bellmouth be perforation height two/
One, so that in injection moulding process, feed liquid smoothly enters and is full of filling slot.
The upper surface of lower cover is provided with the positioning convex of ring-type, and the lower surface of inner sleeve is provided with and positioning convex cooperation
Locating slot 32, positioning convex, locating slot cross section be taper so that inner sleeve press-fit positioning.
In Fig. 1,11 is location hole, is easy to the positioning assembling of motor cover and motor base (frame).
