Abstract
This patented product bearing frame unites two into one an injection moulding with protect line cover, in the back of moulding plastics, to enter the quick pressure equipment when the working of plastics falls to the uniform temperature of copper base porous bearings, the cooling back copper base porous bearings just inlayed inside the bearing frame to automatic aligning function is realized to copper base porous bearings's external diameter arc surface, participate in the root and respectively do a circular arc back chipping, avoid producing the burr.
Description
Technical field
The utility model relates to a kind of automatic self-aligning bearing seat of tube shaped electric machine, and assembling installed by the motor stator and the rotor that are mainly used in tube shaped electric machine.
Background technology
Existing bearing pedestal is engineering plastics due to material, has certain distortion during casting, well can not ensure the concentricity of product, and cause magnetic field unstable, noise is large, and serious causes electric machine chamber-sweeping; Existing bearing pedestal and motor coil sheath are two parts separated, and installation rear motor length is long, and motor is longer, and concentricity requirement is more difficult to ensure card; Existing big envelope four stator pin roots do not have back chipping, produce burr when assembling with stator module 4 location notchs, have gap after causing big envelope and stator to assemble.
Summary of the invention
The problem found for the mode that is connected and fixed of the electric machine rotor of existing tube shaped electric machine and shortcoming, my company designs develops a Noval bearing seat in order to solve the shortcoming of existing product.
The patented product bearing pedestal and wire bushing unite two into one, single injection-molded; After injection moulding, copper base oil containing bearing quick press mounting when working of plastics drops to uniform temperature is entered, after cooling, copper base oil containing bearing is just embedded in bearing pedestal inside, realizes self-aligning function with the outer-diameter circular arc face of copper base oil containing bearing; Pin root respectively does a circular arc back chipping, avoids producing burr.
This utility model product, ensures the concentric of motor with the length of the copper base oil containing bearing on motor bearing seat and reduction motor and beats, reducing the noise of product, decrease electric machine chamber-sweeping problem; Namely single injection-molded solves the problem of concentricity, additionally reduces the secondary operations of product, reduces production cost, turn improve production efficiency.

In figure, 1, bearing pedestal, 2, copper base oil containing bearing, 3, wire bushing, 4, circular arc back chipping, 5, pin root.
Embodiment
The utility model embodiment is provided below in conjunction with accompanying drawing:
As shown in the figure, bearing pedestal 1 and wire bushing 3 unite two into one, single injection-molded; Bearing pedestal 1 and copper base oil containing bearing 2 are by when injection moulding, under bearing pedestal 1 working of plastics is cooled to uniform temperature condition, copper base oil containing bearing 2 quick press mounting when working of plastics drops to uniform temperature is entered, after cooling, copper base oil containing bearing 2 is just embedded in bearing pedestal 1 inside, realize self-aligning function with the outer-diameter circular arc face of copper base oil containing bearing 2, thus reach the automatic aligning centering of rotor in stator interior; Pin root 5 respectively does a circular arc back chipping 4, avoids producing burr.
