Abstract (en)

[origin: EP1914776A1] A bearing assembly of a switching mechanism for an air circuit breaker having multiple rotational shafts, that includes: a trust bearing (3); and a trust bearing support member (4) that includes an axial hole wall (4d), an inner diameter part (4c) contacting with the trust bearing, a flange part (4a) extending from the inner diameter part, a rounded part (4b) formed between the inner diameter part (4c) and the flange part (4a), and an annular recess portion (4e) formed at a lower portion of the flange part by pressing to lengthen the inner diameter part and shorten the length of the rounded part to thus increase the area contacting with the trust bearing. Because the contact area between the trust bearing and the bearing support member is increased, deformation of the bearing support member due to an axial load can be minimized.
