Embodiment 1

[0041] Such as Figure 1 to Figure 5 As shown, the present embodiment discloses a cast iron frame structure of a box-type motor with a single-side air path, including a cast iron frame 4 integrally cast from gray cast iron H250. The cast iron machine base 4 is integrally formed by two side square boxes 41 and a middle cylinder 42 .

[0042] The middle circle 42 includes a core tube, and the upper circumference of the core tube is provided with convex axial inner ribs 43, and the axial air passage of the machine base is formed between the axial inner ribs 43; the inner convex axial ribs 43 not only has an interference fit with the outer diameter of the stator iron core, supports and installs the stator iron core, but also plays a role in strengthening the overall rigidity and strength of the machine base. A radially inner reinforcing rib 44 is also arranged inside the mandrel, and the inner convex height of the radially inner reinforcing rib 44 is lower than that of the axiall...

Embodiment 2

[0051] Such as Figure 6 to Figure 7 As shown, this embodiment discloses a box-type motor, which includes the cast iron base structure of the single-side air passage of the box-type motor described in Embodiment 1, and also includes a stator installed in the cast iron base 4 and a matching rotor.

[0052] The stator is mainly composed of a stator core 8 and a stator winding 7 . The stator core 8 is a clip-type stator core, which is composed of a stator punch, a stator ventilation slot plate, a stator pressure ring and a clip. It is fixed into a whole by the clips evenly distributed around the circumference, so it is called a clip stator core. The structure of the clip-type stator core is the prior art, and the specific structure will not be described in detail.

[0053] The stator core 8 is also provided with a stator temperature measuring element 9 . The stator core 8 is also provided with wire clamps 10, which are evenly distributed on the circumference and welded on the...

Abstract

The invention discloses a cast iron base structure of a box type motor unilateral wind path. Thecast iron base structure comprises a cast iron base which is integrally formed by square boxes at two sides and a middle cylinder; the middle cylinder comprises a core cylinder, inwards-protruding axial inner reinforcing ribs are arranged on the periphery of the core cylinder, and axial ventilation channels of the machine base are formed between the axial inner reinforcing ribs. The inwards-convex axial inner reinforcing ribs are in interference fit with the outer diameter of the stator iron core atthe same time to support and install the stator iron core; radial inner reinforcing ribs are further arranged in the core cylinder, and the inward-protruding height of the radial inner reinforcing rib is lower than that of the axial inner reinforcing rib. The tops of the square boxes on the two sides are provided with an air inlet of a non-shaft-extension end and an air outlet of a shaft-extension end respectively, and the side portions of the square boxes are provided with installation base plates of an auxiliary junction box and a main junction box respectively. According to the invention,motors with all pole numbers and all rated power output at the same center height use the same cast iron base blank, so that the comprehensive cost of the whole machine is effectively reduced while the production and manufacturing period of the base is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of high-voltage and high-efficiency box-type common three-phase asynchronous motors, and in particular relates to a cast iron frame structure with a single-side air path of the box-type motor and the box-type motor. Background technique [0002] High-voltage ordinary three-phase asynchronous motors are widely used in non-explosive environments to drive various fans, compressors, water pumps, cutting machinery, transportation machinery, general machinery and other mechanical equipment. With the increasing demand for ordinary high-voltage three-phase asynchronous motors, since this series of motors does not need to pass the nationally recognized explosion-proof inspection structure to obtain explosion-proof certificates, there are many domestic companies that produce this type of motors, which also leads to this series of motor products. Market competition is also becoming more and more fierce. In recent year...
