Description
Technical field:
The utility model relates to a kind of motor of stretch end cap and application thereof, belongs to technical field of motors.
Background technology:
On stretching end cap, mounting screw has 2 kinds of schemes at present:
The first scheme to be coated with white zine or not to be coated with screw welding overall electrophoresis after stretching end cap of white zine, but in the process of overall electrophoresis, insulating varnish can cover the outside of screw, cause the poor electric conductivity of screw, the earth resistance of motor is defective, simultaneously because insulating varnish can be present among the screw thread of screw, screw thread go-no go gauge is caused to detect defective;
First scheme after stretching end cap electrophoresis completes, the screw riveted joint being coated with white zine is arranged on stretching end cap, but the screw that riveted joint is installed more easily exists compared to the screw of welded and installed the phenomenon got loose, and reliability is relatively low.
Summary of the invention:
The purpose of this utility model is to provide a kind of motor of stretch end cap and application thereof, can ensure that the screw thread of screw can not by the impact of electrophoretic paint, guarantee that the earth resistance of motor is qualified, also to ensure between copper facing screw and stretching end cap, in conjunction with firm, not easily to get loose simultaneously.
The purpose of this utility model is achieved by following technical proposals.
A kind of stretching end cap, end cap is by stamped metal sheets drawing and forming, forms bearing chamber, the outer ledge of end cap is installed by welding with some copper facing screws, arranges insulating lacquer layer at external face at the mid-portion concave of end cap.
End cap described above adopts ferrous material to make.
The quantity of copper facing screw described above is 4, and 4 copper facing screws are evenly arranged along the outer ledge circumference of end cap.
End cap described above also includes bearing, bearing shell fragment and bearing gland, and bearing is located in bearing chamber, and bearing shell fragment is pressed on bearing, and bearing gland covers on bearing, and end cap, bearing shell fragment and bearing gland are installed together.
A kind of motor, comprise rotating shaft, rotor assembly, stator module, casing and end cap, rotor assembly is arranged in rotating shaft, stator module and casing are installed together and are nested in outside rotor assembly, and end cap is arranged on the end of casing, and rotating shaft two ends are bearing on the bearing of end cap respectively, described end cap is by stamped metal sheets drawing and forming, form bearing chamber at the mid-portion concave of end cap, the outer ledge of end cap is installed by welding with some copper facing screws, insulating lacquer layer is set at external face.
End cap described above adopts ferrous material to make.
The quantity of copper facing screw described above is 4, and 4 copper facing screws are evenly arranged along the outer ledge circumference of end cap.
End cap described above also includes bearing, bearing shell fragment and bearing gland, and bearing is located in bearing chamber, and bearing shell fragment is pressed on bearing, and bearing gland covers on bearing, and end cap, bearing shell fragment and bearing gland are installed together described above.
The utility model compared with prior art, has following effect:
1) first on the outer ledge of end cap, some copper facing screws are installed by welding with, after on external face electrophoresis insulating lacquer layer, can ensure between copper facing screw and stretching end cap in conjunction with firm, not easily get loose, also can ensure that the screw thread of screw by the impact of electrophoretic paint, can not guarantee that the earth resistance of motor is qualified simultaneously;
2) end cap adopts ferrous material to make, owing to adopting the mode of anodic electrophoresis, insulating lacquer layer is set at external face, anodic electrophoretic coating is only on the surface that can tolerate anodic electrophoresis process, as iron and nickel use, and can not use on copper, therefore can ensure that the screw thread of copper facing screw by the impact of electrophoretic paint, can not guarantee that the earth resistance of motor is qualified.
