Abstract
The invention discloses a self-aligning bearing holder for a tubular motor. A bearing holder body and a protection sleeve are combined into one and are formed through one-shot injection molding. After injection molding, a copper base oil-impregnated bearing is rapidly pressed into a plastic component when the plastic component cools to a certain temperature. After the cooling process, the copper base oil-impregnated bearing is embedded into the bearing holder body and the exterior diameter arc face of the copper base oil-impregnated bearing can help fulfill the self-aligning function. The Pin roots are provided with an arc clear root each so as to prevent the generation of burrs.
Description
Technical field
The present invention relates to a kind of automatic self-aligning bearing seat of tube shaped electric machine, 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 invention 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.
Accompanying drawing explanation
Fig. 1: structural representation of the present invention
Fig. 2: prior art structural representation before transformation
In figure, 1, bearing pedestal, 2, copper base oil containing bearing, 3, wire bushing, 4, circular arc back chipping, 5, pin root.
Embodiment
The specific embodiment of the invention 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.
