Embodiment

Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.

Like Fig. 1, shown in Figure 2; The present invention includes outer wall 1, non-leading-out terminal ventilating duct 2, inwall 3, cooling water pipe 4, deep bead 5, outer cover 6, support muscle 7, leading-out terminal ventilating duct 8, supporting bracket 9, supporting bracket 10, supporting bracket 11, footing piece 12, brace rod 13, outlet cassette holder 14, sealing plate 15 and sealing plate 16.

Like Fig. 1, shown in Figure 2, cooling water pipe 4 is concentric ring-shaped and distributes, and passes outer wall 1, inwall 3 and deep bead 5.Outer wall 1, inwall 3 are opened concentric annular hole battle array with deep bead 5, are used to install and fix cooling water pipe 4.Support muscle 7 is uniformly distributed with radially, is embedded in inwall 3 and the deep bead 5, and two ends are supported by outer wall 1.Inwall 3 and deep bead 5 have the groove that supplies support muscle 7 to pass except that Kong Zhen.The outer cover 6 whole cylindrical peripheries that are wrapped in support muscle 7, cooling water pipe 4, applying support muscle 7, two ends and outer wall 1 weld together.

Deep bead 5 is positioned in the middle of the iron core shelves, with outer cover 6 welding.Inwall 3 is positioned at iron core shelves two ends.Non-leading-out terminal ventilating duct 2, leading-out terminal ventilating duct 8 are in iron core shelves two ends and inwall 3 and 7 welding of support muscle.Junction box seat 14 is positioned at the motor outlet, is welded on the outer cover 6.Footing piece 12 is positioned at the support bottom, and brace rod 13, supporting bracket 9, supporting bracket 10, supporting bracket 11 are positioned at support bottom and footing piece 12 and outer cover 6 welding, play the integrated support effect with 12 1 of footing pieces.

Outer wall is opened hole for hoist for 1 four jiaos, is used for the motor integral hoisting, and tapped through hole is opened at the lower end surface center, and tapped through hole is positioned at outer cover 6 inside bottom, as delivery port.

Cooling water pipe 4 is flower arrangement from interior circle and distributes, and the gap that is in 4 of the cooling water pipes of same circumference equates, the gap that the cooling water pipe 4 of the interior ring adjacent with support muscle 7 and support muscle are 7 approximates the gap of 4 of cooling water pipes, avoids windage uneven.The distribution of cooling water pipe 4 should be avoided the motor line outlet.

Be in the support muscle 7 at delivery port place, support bottom, fluting prevents to hinder water outlet at the delivery port place, and with expense hole, stator core cooperation place 17 (as shown in Figure 4), be used for fixing feather key, axially directed and radial location when being convenient to the stator core suit.

Leading-out terminal ventilating duct 8 is opened line outlet (as shown in Figure 3) with outer cover 6 at corresponding outlet cassette holder 14 places.

Sealing plate 15, sealing plate 16 are positioned at the place that the iron core shelves do not have cooling water pipe 4 to pass through, and are welded together to form confined space with outer cover 6, support muscle 7, outer wall 3, prevent that the iron core shelves from leaking out to cause inhomogeneous cooling.

The internal diameter of deep bead 5 is used for wind path and separates greater than the stator pressing ring cylindrical, less than circle at the bottom of the interior ring cooling water pipe.The internal diameter of inwall 3 equals the stator pressing ring cylindrical, external diameter is not more than the 3rd ring cooling water pipe distribution circle.The minimum diameter of non-leading-out terminal ventilating duct 2, leading-out terminal ventilating duct 8 is convenient to the stator core suit greater than the stator pressing ring cylindrical, is used for the stator coil end wind-guiding.

Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
