Document Type and Number:
WIPO Patent Application WO/2010/069715
Kind Code:
A3
Abstract:
The invention relates to a machine with a rotor (20), wherein the rotor (20) is mounted in a hub (33) of a housing (13) by means of at least one fixed bearing (34), wherein the fixed bearing (34) is embodied as a roller bearing (28) with an outer ring (35) fixed to the housing (13) by means of a retainer plate (31), at least one fixing element (36) holding the retainer plate (31) to the housing (13), the retainer plate (31) having a radial hole (68) between the fixing element (36) and a central opening (65) in the retainer plate (31) and an external perimeter (74). The retainer plate (31) has a material thickness (h), wherein said hole (68) is completely arranged in a region (77) to both sides of an imaginary line (80), connecting a rotational axis (83) of the rotor (20) and a position of the fixing element (36), said region (77) being defined by two radii (86, 89), from the rotational axis (83) of the rotor (20) separated to both sides of the line (80) by an angle (β), said angle (β) corresponding to a quotient (Q), a numerator being formed from the difference between 360° and n*5° and corresponds to a denominator n, where n corresponds to a number of fixing elements (36), used to hold the retainer plate (31).
