Description
Technical field
The present invention relates to electric motors, be specifically related to motor cover.
Background technology
Existing motor cover offers bearing chamber in centre, and bearing chamber is used for installing bearing, but this motor cover
Lacking 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
Holding the service life with motor, in use there is potential safety hazard, reliability is relatively low.Some motor cover are at 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
Changing whole motor cover, replacement cost is higher.
Summary of the invention
For the problems referred to above, the invention provides motor cover, it can solve the insulation pull-up of prior art middle (center) bearing room
Backwardness need to change the technical problem of whole motor cover.
Its technical scheme is such, and it includes lid, it is characterised in that: described lid is the cylinder knot of both ends open
Structure, it also includes that upper cover plate, bearing block and lower cover, described upper cover plate are provided with and leads to the upper of the shaft hole matching of described bearing block
Hole, described lower cover is provided with the lower through-hole that the installation cavity with described bearing block coordinates, described upper cover plate, lower cover screw thread respectively
Being installed on the cavity upper/lower terminal of described lid, described bearing block outer peripheral face is provided with the snap fit tabs axially extended, described
The cavity of lid is provided with the draw-in groove coordinated with described snap fit tabs, so that described bearing block is sticked in the cavity of described lid,
And press-fit fixing by described upper cover plate, lower cover；
In described bearing block, injection is formed with the insulating barrier on cladding installation cavity surface.
Further, the outer peripheral face of described bearing block is provided with filling slot and connection filling slot and the perforation of installation cavity,
Described insulating barrier is formed with the filling part and connecting portion coordinated with described filling slot, perforation.
Further, described perforation is respectively arranged at two ends with the most tapered bellmouth, and the height of described bellmouth is
/ 2nd of perforation height.
Further, the upper surface of described lower cover is provided with ring-type positioning convex, on the lower surface of described bearing block
Being provided with the locating slot coordinated with positioning convex, described positioning convex, the cross section of locating slot are taper.
The motor cover of the present invention, upper cover plate, lower cover screw thread respectively is installed on the cavity upper/lower terminal of lid, bearing
Seat outer peripheral face is provided with the snap fit tabs axially extended, and the cavity of lid is provided with the draw-in groove coordinated with snap fit tabs, so that axle
Bearing is sticked in the cavity of lid, and press-fits fixing by upper cover plate, lower cover, after insulating barrier comes off, only need to open,
Bottom end cover, pounds out bearing block, changes bearing block, reduces replacement cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, it includes that lid 1, lid 1 are the tube structure of both ends open, it also includes upper cover plate 2, bearing
Seat 3 and lower cover 4, upper cover plate 2 is provided with the upper through hole that the axis hole 35 with bearing block 3 coordinates, and lower cover 4 is provided with and bearing block
The installation cavity of 3 joins the lower through-hole of 36 conjunctions, and upper cover plate 2, lower cover 4 screw thread respectively are installed on the cavity upper/lower terminal of lid 1, axle
Bearing 3 outer peripheral face is provided with the snap fit tabs 31 axially extended, and the cavity of lid 1 is provided with the card coordinated with snap fit tabs 31
Groove, so that bearing block 3 is sticked in the cavity of lid 1, and press-fits fixing by upper cover plate 2, lower cover 4；
In bearing block 3, injection is formed with the insulating barrier 5 on cladding installation cavity surface.
The outer peripheral face of bearing block 3 is provided with filling slot 33 and connection filling slot and the perforation 34 of installation cavity, bores a hole 34 liang
End is respectively equipped with the most tapered bellmouth, and the height of bellmouth is 1/2nd of perforation height, and insulating barrier 5 is formed
The filling part coordinated with filling slot, perforation and connecting portion, in order in injection moulding process, feed liquid is easily accessible in filling slot.
The upper surface of lower cover 4 is provided with ring-type positioning convex 32, and the lower surface of bearing block 3 is provided with and positioning convex
The locating slot coordinated, positioning convex 32, the cross section of locating slot are taper, in order to preferably press-fit fixed bearing block 3.
In Fig. 1,11 is hole, location, it is simple to the location assembling of motor cover and motor base (frame).
