Abstract

The invention discloses a double-fed wind driven generator novel seam allowance assembling structure comprising a machine support (1) and an end cap (2). The machine support (1) is provided with an inner seam allowance (3). The end cap is provided with an outer seam allowance (4). A gap exists between an outer circumference surface of the outer seam allowance (4) of the end cap (2) and an inner circumference surface of the inner seam allowance (3) of the machine support (1). A plurality of positioning holes A (5) are arranged uniformly along a circumferential direction on the end cap (2). The machine support (1) is provided with positioning holes B (6) matched with the positioning holes A (5). Positioning pins (7) are arranged inside the positioning holes A (5) and the positioning holes B (6). The invention also discloses an assembling method for the assembling structure. The beneficial effects of the present invention are that: problems of air gap uniformity and concentricity of front and back end cap bearing chambers are solved; the consistency of the double-fed wind driven generator novel seam allowance assembling structure is good, so that smooth bearing maintenance in wind fields is possible; the structure is more stable, and scratches do not easily occur; long-term operation is facilitated; and the economical efficiency is good.

Description

technical field

[0001] The invention relates to the technical field of assembly structures of wind power generators, in particular to a novel seam assembly structure and an assembly method of a double-fed wind power generator. Background technique

[0002] Most wind turbines are assembled with seams to ensure that the concentricity of the centerlines of the front and rear bearing chambers cannot meet the requirements. The precision of the equipment ensures the quality of the products and ensures the consistency of the products.

[0003] However, when assembling the end cover, it is easy to cause scratches on the edge of the bearing, and it is not easy to find out during the factory test. Motors with bearing scratches or slight damage can still pass the test and be shipped, leaving quality risks for later operation; It is difficult to maintain the wind farm. The end cover cannot be disassembled under the condition of limited cabin space and limited tools. Forcible disassembly...
