摘要： PURPOSE: To provide a device for transferring a pressure medium which can be economically manufactured and can be variously used. CONSTITUTION: An outer component 21 is fixed to the casing 2 of a machine tool M directly or through an intermediate member 12, and an inner component 31 is fixed to a spindle 3 rotatably supported in the inside of the casing 2 directly or through an intermediate member 5 radially spaced at a distance from the outer component 21. Intermediate members 41, 42 which are retained not to be relatively rotated are arranged in an area of pressure medium ducts 26, 27 or 36, 37. The intermediate members have at least one duct connecting the pressure medium duct 26 or 27 of the outer component 21 to the pressure medium duct 36 or 37 of the inner component 31, are laterally supported at one of the components, advantageously at the inner component 31, through two radially extending sealing gaps, and are displaceable to the other of the components.

摘要： PROBLEM TO BE SOLVED: To prevent abrasion caused by the increase of friction in a pressure medium supply device. SOLUTION: One or a plurality of circumferential pressure chambers 29, 30 is formed in a fixed member 2 and (or) end surfaces 23, 24 of rotating members 3, 3' which define sealed clearances 15, 16 directed in a radial direction. The pressure chambers 29, 30 communicate with an annular groove 14 arranged among the fixed member 2 and the rotating members 3, 3' through one or a plurality of adjusting slits 37, 38 directed in the radial direction. The fixed member 2 and (or) the end surfaces 23, 24 of the rotating members 3, 3' which define the sealed clearances 15, 16 directed in the radial direction and are equipped with the pressure chambers 29, 30 are so formed that their areas are equal to each other.

摘要： PROBLEM TO BE SOLVED: To extremely simplify constitution, thus to not only manufacture economically but also reliably and automatically regulate the width of a seal gap in a radial direction, besides, to be regulated regardless of the working pressure of a pressure medium to be transmitted and the number of relative revolutions between a member arranged in a position fixed state and a rotationally driving member, in a pressure medium feeding device to feed a pressure medium from a member arranged in a position-fixed state to a rotationally driving member. SOLUTION: A ring 13, held in a displacing manner, of a member 2 arranged in a position fixed state is provided at an end face 16 on the sealed gap 11 side with an intermediate pressure chamber 31 with a radial direction from the annular groove 18 of the sealed gap 11. The intermediate pressure chamber 31 is always communicated with a regulation pressure chamber 35 through pipe lines 36 and 37 formed in an axially displacing ring 13.

摘要： The device has a motor with a changeover function, and a draw rod. A driveline (13) is provided between the motor and the draw rod. The driveline has a set of gearing units that convert rotational displacement movements of a drive unit of the motor into axial displacement movements of the rod. The driveline is configured as a bell that engages with an intermediate unit using an internal thread in the bell.

摘要： The servo device (1) has a rotary cylinder (3) and a sliding piston (4) supplied with a pressure medium on one or both sides, for corresponding displacement of a setting element (9) of the rotary machine tool (2). The actual position of the setting element is determined via a reflective surface (20) of the sliding piston, inserted in the path of sound waves between a transmitter (11) and a receiver (12), with calculation of the piston position by evaluation of the time difference between the transmitted and received sound wave signal. An Independent claim for a method for determining the position of a setting element for a rotary machine tool is also included.

摘要： In an arrangement (1) for the transmission of a pressurized medium from a fixed, outer component (21) into a rotating, inner component (31) which are provided with allocated pressurized-medium passages (26, 27 and 36, 37 resp.), the outer component (21) is fastened to a housing (2) of a machine (M), and the inner component (31) is fastened at a radial distance from the component (21) to a spindle (3). In addition, to compensate for the radial distance, in each case an intermediate piece (41, 42) held in a rotationally locked manner is inserted between the outer component (21) and the inner component (31). The intermediate piece (41, 42) is provided with a passage (45 or 46), is laterally supported on one of the components via in each case radially directed sealing gaps (47, 48 and 49, 50 resp.) and is adjustable relative to the other component (21). This ensures that the two components (21, 31) are not directly supported on one another and do not enclose an axial sealing gap, but nonetheless transmission of pressurized medium is possible. Positional changes of the components (21, 31) are also automatically compensated for and positional inaccuracies cannot have an adverse effect.
