    • A locking device for a shaft (4) arranged in a cylindrical bearing (5.1) in a housing (5), said bearing (5.1) comprising a sleeve with a membrane that communicates with a space (7.4) containing a first pressure medium. The first space (7.4) communicates with a primary piston arrangement (7) via the first pressure medium. The primary piston arrangement (7) is also in mechanical connection with a secondary piston arrangement (8) that in turn communicates with a pressure source for a second pressure medium. The shaft (4) can be locked to prevent turning or axial displacement in relation to the housing (5) when increased pressure is applied to the second pressure medium, which in turn causes increased pressure in the first pressure medium and an elastic decrease in diameter in the membrane of the sleeve (5.1).
    • 一种用于轴(4)的锁定装置,其布置在壳体(5)中的圆柱形轴承(5.1)中,所述轴承(5.1)包括具有与包含第一压力介质的空间(7.4)连通的膜的套筒。 第一空间(7.4)经由第一压力介质与主活塞装置(7)连通。 主活塞装置(7)也与次级活塞装置(8)机械连接,次级活塞装置(8)又与用于第二压力介质的压力源连通。 当增加的压力施加到第二压力介质时,轴(4)可以被锁定以防止相对于壳体(5)的转动或轴向位移,这又导致第一压力介质中的压力升高和直径的弹性减小 在套筒的膜(5.1)中。
