FIELD: physics, control. ^ SUBSTANCE: invention relates to mounting assembly of switching assembly for air circuit breaker with multiple turning shafts. Mounting assembly comprises: thrust bearing, which supports at least one of turning shafts; thrust bearing supporting element, which comprises a wall of axial bore for the turning shaft; a part with inner diameter, which contacts with the thrust bearing, flanged part, extending fron the inner diameter part, rounded part formed by inner diameter part and flanged part, and annular recessed part in the lower section of the flanged part formed in order to extend the inner diameter part and to reduce length of the rounded part, which is necessary to increase the area of contact with the thrust bearing. Increased area of contact between the thrust bearing and its supporting element provides for minimised strain of the bearing supporting element caused by axial load. ^ EFFECT: minimised strain of the bearing supporting element caused by axial load. ^ 3 cl, 9 dwg |
