Abstract

1. Магнитная опора, преимущественно для быстроходных динамических нагруженных турбохолодильников, состоящая из осевого электромагнитного подшипника и радиального магнитного подшипника, выполненного в виде набора кольцевых постоянных магнитов прямоугольного сечения с чередующимся направлением намагниченности, установленных на статоре и роторе с проставками, отличающаяся тем, что, с целью уменьшения аксиальной силы, действующей на ротор опоры, кольцевые магниты на роторе и статоре выполнены с осевой намагниченностью и имеют разную осевую длину.2. Магнитная опора по п.1, отличающаяся тем, что, с целью уменьшения массы ротора проставки между кольцевыми постоянными магнитами на роторе выполнены из материала малой плотности, а кольцевые постоянные магниты на роторе имеют меньшую осевую длину, чем магниты на статоре.3. Магнитная опора по пп.1 и 2, отличающаяся тем, что, с целью обеспечения прочности кольцевых постоянных магнитов на роторе на них установлены с натягом немагнитные бандажные кольца.1. Magnetic bearing, mainly for high-speed dynamic loaded turbo-coolers, consisting of an axial electromagnetic bearing and a radial magnetic bearing, made in the form of a set of annular permanent magnets of rectangular cross section with alternating direction of magnetization installed on the stator and the rotor with spacers, different in order to reduce the axial force acting on the support rotor, the ring magnets on the rotor and stator are made with axial magnetization and have different axes Its length.2. Magnetic bearing according to claim 1, characterized in that, in order to reduce the mass of the rotor, the spacers between the annular permanent magnets on the rotor are made of a material of low density, and the annular permanent magnets on the rotor have a smaller axial length than the magnets on the stator. Magnetic bearing according to claims 1 and 2, characterized in that, in order to ensure the strength of the annular permanent magnets on the rotor, non-magnetic retaining rings are installed on them with tension.
