Description

A motor housing

technical field

The utility model relates to a cylindrical component, in particular to a motor casing.

Background technique

Existing motor housings require cooling in many cases. The current structures are mainly as follows: one is to use profiles for processing, but the pipelines can only be straight pipes, the structure of the waterway is complicated, the cost is high, and it will affect the rigidity of the shell; the other is to process with buried pipes. The cooling pipe is pre-embedded in the wall thickness of the motor casing. This kind of processing technology is complex and requires high-cost mold investment to realize; the third is socket processing, that is, the motor casing is set as an inner casing and an outer casing. body, and a cooling pipe is set between the two shells, but this structure has poor rigidity and high cost.

Utility model content

The technical problem to be solved by the utility model is to provide a motor casing with convenient processing, low cost, good rigidity and good cooling effect.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a motor housing, including a motor housing body and end caps arranged at both ends of the motor housing body, the motor housing The body includes a plurality of juxtaposed ring members formed by a hollow metal tube spiraling continuously around the axis. The two ends of the hollow metal tube are respectively provided with an inlet and an outlet, and the ring members are fixed by welding.

The ring members are fixed by intermittent welding spot welding.

There is a gap between the ring members.

The ring members are welded and fixed through continuous welding layers.

The ring member is an annular member.

The ring member is a rectangular ring member, a polygonal ring member or a special-shaped ring member.

The cross-sectional shape of the hollow metal tube is circular, rectangular, polygonal or irregular.

Compared with the prior art, the utility model has the advantage of using a hollow pipe to form a plurality of juxtaposed ring members by coiling, and then connecting and fixing adjacent ring members to form a motor housing body, which not only The cooling effect is greatly improved, and the processing is greatly facilitated, and the processing cost and material cost are greatly reduced; at the same time, compared with the prior art, the rigidity of the entire shell is also greatly increased under the same cylinder wall thickness; The utility model only needs to use a simple bending die to process the motor housing body of any shape and size; in many cases, it can be welded and fixed by intermittent welding points, which can save processing costs; in addition, setting the gap The heat dissipation effect can be improved; and the annular components can be sealed with each other through continuous welding layer welding, which can usually be used to make motor housings with sealing requirements.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

Embodiment 1: A motor housing, including a motor housing body 1 and end caps 2 arranged at both ends of the motor housing body 1, the motor housing body includes a hollow metal tube 11, the hollow metal tube 11 The cross-sectional shape of the shape is square, and the two ends of the hollow metal tube 11 are respectively provided with an inlet 12 and an outlet 13. The hollow metal tube 11 spirals continuously around the axis to form a plurality of juxtaposed ring members 14, and the ring members 14 are circular ring members. The ring members 14 are welded and fixed by discontinuous welding points 15 , and gaps 16 are provided between the ring members 14 .

Embodiment 2: A motor housing, including a motor housing body 1 and end caps 2 arranged at both ends of the motor housing body 1, the motor housing body includes a hollow metal tube 11, the hollow metal tube 11 The cross-sectional shape of the external shape is hexagonal. The two ends of the hollow metal tube 11 are respectively provided with an inlet 12 and an outlet 13. The hollow metal tube 11 spirals continuously around the axis to form a plurality of parallel ring members 14. The ring members 14 are circular. Components, the ring components 14 are welded and fixed by a continuous welding layer 17 .

In the above embodiments, the ring member 14 can also be a rectangular ring member, a polygonal ring member or a special-shaped ring member, and the cross-sectional shape of the hollow metal tube 11 can also be a circle, a polygon or a special shape.
