Abstract
The utility model discloses a kind of electric machine casing, comprise electric machine casing body and the end cap being arranged on electric machine casing body two ends, electric machine casing body comprises the annular construction member multiple arranged side by side be made up of a hollow metal pipe revolved around reel continuously, the two ends of hollow metal pipe are respectively arranged with import and outlet, be welded and fixed between annular construction member, advantage is the pipe of a use hollow, multiple annular construction member arranged side by side is formed by spiraling, then be connected and fixed by the adjacent annular construction member of welding and constitute an electric machine casing body, not only cooling effect improves greatly, and greatly facilitate processing, processing cost and material cost all significantly reduce, meanwhile, relative to prior art, when same cylindrical shell wall thickness, the rigidity of whole housing also increases greatly.
Description
Technical field
The utility model relates to a kind of cylindrical member, especially relates to a kind of electric machine casing.
Background technology
Existing electric machine casing needs cooling in many cases.Current structure is mainly following several: one is utilize section bar to process, but pipeline wherein can only be straight tube usually, and waterway structure is complicated, cost is high and can affect the rigidity of housing; Two is buried tube type processing, and be embedded into by cooling water pipe in the wall thickness of electric machine casing, this processing technology is complicated, and the mould needing cost higher drops into and could realize; Three is socket joint type processing, be arranged to inner housing and shell body, and arrange cooling water pipe between two-layer housing, but this structural rigidity is poor, and cost is higher by electric machine casing.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of easy to process, cost is low, good rigidly and the electric machine casing of good cooling results.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of electric machine casing, comprise electric machine casing body and the end cap being arranged on described electric machine casing body two ends, described electric machine casing body comprises the annular construction member multiple arranged side by side be made up of a hollow metal pipe revolved around reel continuously, the two ends of described hollow metal pipe are respectively arranged with import and outlet, are welded and fixed between described annular construction member.
Pad by being interrupted between described annular construction member is welded and fixed.
Gap is provided with between described annular construction member.
Be welded and fixed by continuous print weld layer between described annular construction member.
Described annular construction member is annular component.
Described annular construction member is rectangular loop component, polygon annular construction member or Special-shaped annular component.
The shape of cross section of described hollow metal pipe profile is circle, rectangle, polygon or abnormity.
Compared with prior art, the utility model has the advantage of the pipe of a use hollow, multiple annular construction member arranged side by side is formed by spiraling, then be connected and fixed by the adjacent annular construction member of welding and constitute an electric machine casing body, not only cooling effect improves greatly, and greatly facilitating processing, processing cost and material cost all significantly reduce; Meanwhile, relative to prior art, when same cylindrical shell wall thickness, the rigidity of whole housing also increases greatly; The utility model only needs to use simple bend pipe mould namely can process the electric machine casing body of arbitrary shape and size; In many cases, can be welded and fixed by the pad be interrupted, can processing cost be saved like this; In addition, gap is set and can improves radiating effect; Then can make mutually to seal between annular construction member by the welding of continuous print weld layer, usually may be used for the electric machine casing being manufactured with seal request.
