Description
Technical field
The utility model is related to machine field, and in particular to a kind of Split type electric cover.
Background technology
Existing motor cover offers bearing chamber in centre, and bearing chamber is used to install 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 is relatively low in use.Some motor covers are noted on the inwall of bearing chamber
Modeling is formed with insulating barrier, and to prevent the generation of shaft current, but after long-term use, insulating barrier is easy to fall off, need to change whole motor
Lid, replacement cost is higher.
Utility model content
Regarding to the issue above, the utility model provides a kind of Split type electric cover, and it can solve prior art middle (center) bearing
The insulating barrier of room needs to change the technical problem of whole motor cover after coming off.
Its technical scheme is such, and it includes lid and bearing block, and the installation cavity surface of the bearing block is provided with insulation
Layer, it is characterised in that：Mounting groove is provided with the lid and hole is tapped, the percussion hole position is in the mounting groove top and connects
Lead to the mounting groove, the bearing block is arranged in mounting groove, bottom end cover screw thread is installed on mounting groove openend and against described
Bearing block.
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
The upper positioning convex of locating slot cooperation is stated, the percussion hole connects the upper locating slot；
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.
Split type electric cover of the present utility model, is provided with mounting groove and taps hole in lid, tap hole position on mounting groove
Portion simultaneously connects mounting groove, and bearing block is arranged in mounting groove, and bottom end cover screw thread is installed on mounting groove openend and against bearing
Seat, after insulating barrier comes off, only need to open bottom end cover, and bearing block is knocked out, and change bearing block, 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 out.
