Embodiment 1

[0025] see figure 1 , image 3 with Figure 5 , splicing the connector 1 on one split piece 4 with the connecting groove 5 on the other split piece 4, several split pieces 4 are finally spliced ​​into a shell 10, and bolts are passed through the bolts on the split piece 4 The hole 2 connects the housing 10 with the front end cover 11 and the rear end cover 14, the inner ring of the stator 9 and the housing 10 is an interference fit, and the two ends of the water guide hole 3 are equipped with gaskets 13 to prevent the cooling water from overflowing. Cooling water enters the water guide hole 3 through the water inlet 15, flows into the next water guide hole 3 through the end cover groove 12, flows back and forth in the interlayer of the housing 10, and finally flows out from the water outlet 16 (see Image 6 ), and take away the heat generated by the motor.

Embodiment 2

[0027] see figure 2 , Figure 4 with Figure 5 , splicing the connecting head 6 on one split piece 4 with the connecting groove 8 on the other split piece 4, several split pieces 4 are finally spliced ​​into a shell 10, and bolts are passed through the bolts on the split piece 4 The hole 2 connects the housing 10 with the front end cover 11 and the rear end cover 14, the inner ring of the stator 9 and the housing 10 is an interference fit, and the two ends of the water guide hole 3 are equipped with gaskets 13 to prevent the cooling water from overflowing. Cooling water enters the water guide hole 3 through the water inlet 15, flows into the next water guide hole 3 through the end cover groove 12, flows back and forth in the interlayer of the housing 10, and finally flows out from the water outlet 16 (see Image 6 ), and take away the heat generated by the motor through the fins 7 on the water guide hole 3 .

Abstract

The invention provides a split extruded and spliced water-cooled motor shell. One end of each splitting piece of the shell is provided with a connector, and the other end of the splitting piece is provided with a connecting trough. Water guide holes are reserved on the splitting piece. One side of the splitting piece is provided with bolt holes. The splitting pieces are spliced by the connectors and the connecting troughs to form the shell. A stator is in interference fit with the inner ring of the shell. The shell is connected with a front end cover and a rear end cover. The two ends of the water guide hole are provided with a gasket respectively. One end of the water guide hole is communicated with an end cover groove. The motor shell is equally divided into a plurality of splitting pieces, has a small volume and is convenient to transport and store. A plurality of water guide holes are extruded on the middle parts of the splitting pieces and may be provided with fins so as to be favorable for water cooling. The shell can be designed into a plurality of shapes such as a polygon, a round and the like according to needs.

Description

technical field [0001] The invention relates to the field of motors, in particular to a split-extrusion-spliced ​​water-cooled motor casing. Background technique [0002] At present, the aluminum alloy housing of traditional water-cooled motors usually adopts manufacturing methods such as gravity casting, inner and outer jackets respectively extruded and welded at the end. Gravity casting is loose in material, low in strength, and has the risk of water seepage; the welding process of the extruded end of the inner and outer jackets is complicated, the extrusion equipment is large, the volume is large, and transportation is inconvenient, and cracks are prone to occur at the weld and there is a risk of water seepage. Contents of the invention [0003] The object of the present invention is to provide a split-extruded spliced ​​water-cooled motor casing that can be spliced ​​into various motor casing shapes. [0004] To achieve the above object, the technical solution of the ...
