    摘要： Disclosed is a barrel-shaped component and a container and an electric motor housing based thereon. The barrel-shaped component comprises a hollow metal pipe (11), wherein two ends of the hollow metal pipe (11) are respectively provided with an inlet (12) and an outlet (13). The hollow metal pipe (11) continuously spirals around an axis to form a plurality of annular components (14) arranged in parallel, wherein the annular components (14) are welded and fixed to each other. A component of any shape and size can be processed by using a simple elbow mould, thereby improving the cooling effect, lowering the processing cost and the material cost, and increasing the rigidity of the whole component where the barrel has the same wall thickness.

    摘要： The present invention provides a friction minimized bearing structure, which is operated in a same-speeded and contrary-directional manner, and actives an inner ring and an outer ring to rotate synchronously in contrary directions. Otherwise, rollers are mounted on a supporting gear module, the roller contacts with the outer ring of the bearing structure and rotate in contrary directions within the same rotation speed, therefore achieves a friction-minimized bearing structure. The bearing structure of present invention makes the relative velocity between the balls and the inner ring, and the outer ring is relatively down to zero or nearly zero. With such manner, an inner friction between the balls, inner ring and the outer ring may be relatively down to zero or nearly zero so as to achieve the objective of minimizing the friction.
