Abstract
The utility model provides a prevent motor cover of shaft current, it not only can solve the technical problem that current motor cover easily formed the shaft current, can also solve the technical problem because of the oscillation generation noise. It is including insulating lid, the internal ab intra of insulating lid and mold insert and lid support mold insert are supported to the outer coaxial bearing room that is packaged with, the mold insert lock is supported on the bearing room of insulating lid in the bearing room, the bearing room supports that the mold insert includes the sleeve and from the annular turn -ups of the inside extension of sleeve upper end opening part, sleeve, turn -ups respectively with lateral wall, the roof parallel arrangement of bearing room.
Description
Technical field
This utility model is related to machine field and in particular to a kind of motor cover of anti-shaft current.
Background technology
Existing motor cover offers bearing chamber in centre, and bearing chamber is used for installing bearing, but this motor cover lacks
The design of anti-shaft current, easily forms shaft current between motor cover, bearing and rotating shaft, and shaft current can have a strong impact on bearing and electricity
, there is potential safety hazard in the service life of machine, reliability relatively low in use.Some electric motor end caps are embedding in the inwall of bearing chamber
Set is provided with insulating sleeve, and insulating sleeve is fixedly connected with end cap by flange and projection, and this structure is not only assembled more numerous
Trivial, higher to the fitted position requirement of each part, and between being also easy to produce between insulating sleeve, flange and the faying face of electric motor end cap
Gap, leads to during motor work because vibration produces noise.
Utility model content
For the problems referred to above, this utility model provides a kind of motor cover of anti-shaft current, and it can not only solve existing
Motor cover easily formed shaft current technical problem moreover it is possible to solve because vibration produce noise technical problem.
Its technical scheme is such, and it includes the lid that insulate, and in described insulating lid body, from-inner-to-outer coaxial packaging has axle
Holding room supports mold insert and lid to support mold insert, and described bearing chamber supports mold insert to be fastened on the bearing chamber of insulation lid, described axle
Holding room supports mold insert to include sleeve and the annular flange extending internally from sleeve upper end open, and described sleeve, flange are respectively
It is arranged in parallel with the side wall of described bearing chamber, roof.
Further, described lid supports mold insert and described bearing chamber to support and be connected with reinforcement between mold insert, described lid
Body supports mold insert and described bearing chamber to support and is provided with two groups of reinforcements between mold insert, and every group of reinforcement has and be annularly distributed and be spaced
Setting.
Further, described lid supports edge, bearing chamber to support and is evenly distributed with perforation on mold insert and reinforcement, described wears
Hole two ends have tapered opening.
Motor cover of the present utility model, because lid supports mold insert coaxial packaging in insulating lid body, and is fastened on insulation
On the bearing chamber of lid, it is avoided that extra assembly manipulation, and is seamless connection with insulation lid, can reduce because of motor
The noise that vibration produces；Lid supports the setting of mold insert to be able to ensure that the mechanical strength of motor cover.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of perforation of the present utility model.
Specific embodiment
As shown in Figure 1 and Figure 2, it includes the lid 1 that insulate, and in insulating lid body, from-inner-to-outer coaxial packaging has bearing chamber to support
Mold insert and lid support mold insert 2, and bearing chamber supports mold insert to be fastened on the bearing chamber 8 of insulation lid, and bearing chamber supports mold insert bag
Include sleeve 32 and the annular flange 31 extending internally from sleeve 32 upper end open, sleeve 32, flange 31 respectively with bearing chamber
Side wall, roof be arranged in parallel.
Lid supports mold insert 2 and bearing chamber to support and be connected with two groups of reinforcements between mold insert, respectively reinforcement 5, reinforcement
Muscle 4, every group of reinforcement has distribution annular in shape interval setting.
Lid supports edge, bearing chamber to support and is evenly distributed with perforation 7 on mold insert and reinforcement（Not shown in FIG. 1）, wear
Hole two ends have tapered opening 71, and wherein, the ratio of the height h of the tapered opening 71 and height H of perforation 7 is 1：3~1：2, taper
Opening 71 outside diameter D is 2 with the ratio of inside diameter d：1~3：1, so that insulation feed liquid is rapidly filled with wearing in injection moulding process
Hole.
