摘要： An improved sealing structure for a pressure fluid cylinder of the type comprising a cylinder, a longitudinal slot in the cylinder, and a driver attached to a piston movable in the cylinder, the driver extending through the slot. The sealing structure includes a strip positioned to overlie the slot in the sealing relation, the strip extending into sealing contact with the inside surface of the cylinder on opposite sides of the slot. That inside surface area of the cylinder which the strip overlies in sealing relation is provided with a cross-sectional radius greater than the cross-sectional radius of that cylinder surface area not in contact with the strip. Preferably the strip is chamfered on its inside surface toward its edges so that the height of the opposed strip edges is no greater than 0.1 mm.

摘要： A ball screw is provided in which the balls coacting with the screw and running in helical threads therein also run in parallel grooves of a raceway ring arranged coaxially about the screw. The grooves extend perpendicularly to the axis of the screw. The ring is freely rotatably mounted, but axially immobile in a nut element arranged coaxially around the raceway ring. A ball cage is arranged between the screw and the raceway ring and attached to the nut element.

The second body (5) has threads (6) cooperating with the threads (4) of the rollers (3), and teeth (11) cooperating with the teeth (9) of the rollers. The threads (2, 4, 6) of the first body (1), the rollers (3) and the second body (5) are trapezoidal threads, the threads of the rollers (3) and the threads of the second body (5) having the same turning direction and the threads of the first body (1) having a turning direction opposite to the turning direction of the rollers and the second body. The pitch circle (14) of the teeth (8) of the first body (1) is located at some distance from the average diameter (15) of the threads (2) of the first body (1) and the pitch circle (16) of the teeth of each roller (3), respectively, is located at some distance from the average diameter (17) of the threads (4) of the roller.
