Description

Dove tail muscle of hydroelectric generator stator

Technical Field

The utility model relates to a dove tail muscle technical field specifically is a dove tail muscle of hydroelectric generator stator.

Background

The stator of the hydroelectric generator is large in size, the silicon steel sheet needs to be positioned by using the positioning ribs, the existing positioning ribs are mainly designed into a shape with a dove tail, the manufacturing difficulty is high, and the machining process is complex.

Disclosure of Invention

The utility model aims at providing a dove tail muscle of hydroelectric generator stator is provided in order to solve the shape that current location muscle mainly designed banding dove tail, and its preparation degree of difficulty is great, the more complicated problem of processing technology.

The utility model has the following concrete scheme: the utility model provides a dove tail muscle of hydroelectric generator stator, includes dove tail muscle body, dove tail muscle body one end is equipped with the screw hole, and dove tail muscle body cross section is symmetrical structure, and its top both sides are equipped with outside convex triangle-shaped A, and triangle-shaped A's a limit and top surface coincidence, cross section bottom both sides are equipped with outside convex triangle-shaped B, and triangle-shaped B is equilateral triangle-shaped, and triangle-shaped B's summit and triangle-shaped A's summit are located same vertical plane.

Distance A between two triangle-shaped A's summit is 48mm, the high B position 50mm of cross section, intermediate position width C is 40 mm.

A gap is arranged between the middle part and the triangle A and the triangle B.

Compared with the prior art, the utility model has the following advantages: the structure is simpler, the processing technology is simplified, and the positioning is more accurate.
