Abstract: This invention pertains to the technical field of vibratory pneumatodynamic bearings. The technical problem is to reduce bearing weight while not increasing pitch and yaw. This is accomplished by employing a transducer (41) including an elongated tube (42) with a shorter tube (44) which are bonded together, with one inside the other. This invention may be used in actuators for magnetic recorders. In one case elongated inner tube (42) is joined to the inner surface of the shorter outer tube (44). Transducer (41) carries a load at points of low vibration on inner tube (42). The outer tube (44) is piezoelectrically excited. The tubes (40, 42) are cylindrical and inner glass tube (42) rides on cylindrical rod (40). The mounting points are at saddle points (S, Fig. 7) on inner tube (42). The short outer tube (40) reduces transducer weight. Alternatively outer tube (90)can be longer than inner tube (91). In that case, outer tube supports tube (93), which rides on it.

Abstract translation: 本发明涉及振动气动轴承技术领域。 技术问题是减少轴承重量，同时不增加俯仰和偏航。 这是通过使用包括具有较短管（44）的细长管（42）的换能器（41）来实现的，所述管（44）彼此粘合在一起。 本发明可以用于磁记录器的致动器。 在一种情况下，细长内管（42）连接到较短外管（44）的内表面。 换能器（41）在内管（42）上的低振动点处承载负载。 外管（44）被压电激励。 管（40,42）是圆柱形的并且内部玻璃管（42）骑在圆柱形杆（40）上。 安装点位于内管（42）的鞍点（S，图7）。 短外管（40）减小了换能器的重量。 或者，外管（90）可以比内管（91）长。 在这种情况下，外管支撑安置在其上的管（93）。
