摘要： The invention relates to an escalator or moving walkway that includes a drive shaft rotating at a relatively low peripheral speed around a horizontal axis and at least one sealing element associated with the drive shaft. Lubricant is supplied to the drive shaft and can escape from leakages at the one sealing element. A device is provided for a permanent recirculation of the lubricant escaping from the leakages. The device includes at least one conveyor element arranged downstream of the sealing element, seen in the direction of the leakage, and at least one recirculation element for the lubricant. The recirculation element cooperates with the conveyor element to return the lubricant into a region upstream of the at least one sealing element.

摘要： A seal for hydraulically sealing a piston rod that travels axially into and out of a housing, preferably in a hydraulic dashpot. The seal comprises a preferably resilient-plastic sealing component (5). The sealing component is provided with one or more sharp ridges (10, 11, & 12) that rest against the piston rod, is tensioned across an elastomeric component (8), and is radially and axially secured along with the latter in a seal holder (2). The sealing component has an axial cylindrical wall (6) and a radial annular flange (7). The wall rests snug against the piston rod. The elastomeric component is annular and is provided with an inner surface (9) that tapers in toward the center of the housing and that the wall rests against. The outer surface of the elastomeric component is accommodated subject to radial tension in a setback (13) in the seal holder. The object is a seal that will satisfactorily prevent the escape of fluid at low temperatures, whereby the sealing component will be subjected to minimal force at high temperatures. The radial tension accordingly varies along the axial height (16) of the elastomeric component.

摘要： An improved generally annular split sealing ring includes generally curved radially inner and outer surfaces and opposed first and second axial surfaces extending between the inner and outer surfaces. The sealing ring has an axially extending, radially centered axis and a cut extend therethrough from the inner radial surface to the outer radial surface to create a gap to facilitate installation and removal of the sealing ring. The cut extends through the sealing ring along a single continuous cut plane. The orientation of the cut plane is determined by establishing a first reference plane extending radially through the sealing ring and generally parallel to and through the axis. A second reference plane extends generally perpendicular to the first reference plane and midway between the first and second axial surfaces to establish a first generally radially extending reference line. A third reference plane extends generally perpendicular to the first and second reference planes and midway between the inner and outer radial surfaces to establish a second generally axially extending reference line and a third reference line. The cut plane is oriented at a first predetermined angle with respect to the second reference plane and the first reference line and at a second predetermined angle with respect to the third reference plane and the third reference line.

摘要： A seal arrangement comprising three sealing rings. The first ring is intended to locate in a groove in a first machine element and has a bearing surface by which it is bearable against the base of the groove of the first machine element, and a surface spaced from its bearing surface. The second ring has a first bearing surface by which it is bearable against the spaced surface of the first ring, and a second bearing surface which is spaced from its first bearing surface, contactable with surface portions of a second machine element and has an annular groove. The third ring is intended to locate in the annular groove of the second sealing ring and has a first bearing surface by which it is bearable against a wall portion of the groove of the second sealing ring, and a second bearing surface which is spaced from its first bearing surface and which is bearable against the second machine element. The second ring has a modulus of elasticity which is greater than that of the first ring and greater than that of the third ring. The third ring is of such a size and shape that when it is located in the groove of the second ring a radial spacing between its second bearing surface and the first bearing surface of the second ring is at least equal to a radial distance between the second and first bearing surfaces of the second ring.

摘要： A gland for compressing packings in the receptacle of a stuffing box has a washer-like stamping made of metallic sheet material and bearing against the exposed side of the outermost packing, and a cupped section whose flange is axially movably secured to the receptacle and whose cylindrical portion is spot welded or riveted to the stamping. The cylindrical portion of the cupped section has reinforcing ribs which extend in parallelism with the shaft or spindle which is engaged by the packing and which may comprise portions extending into the flange substantially radially of the shaft or spindle. The second section is made by deep drawing of corrosion-resistant sheet steel. The inner surfaces of the stamping and second section are out of contact with the shaft or spindle but the periphery of the stamping is in sliding contact with the internal surface of the receptacle.

摘要： A packing gland assembly providing separate tightening of a packing seal in both the axial and radial directions. Tightening of the packing seal in the aforesaid directions is provided by a pair of concentric sleeves mounted about a shaft wherein the latter may experience either rotational or axial movement or both with respect to a housing surrounding the shaft. The packing seal is disposed on the shaft with one of its axial end faces abutting the housing with the other of its end faces abutting the inner sleeve. With the inner sleeve being selectively positioned in an axial direction, the axial pressure on the packing seal can be adjusted. In addition, a segmented ring is provided to encompass the packing seal to urge the latter into radial engagement with the shaft. The outer surface of the segmented ring is beveled to engage the outer sleeve in a wedge type of manner so that upon selected axial movement of the outer sleeve, the segmented ring adjustably tightens the packing seal against the shaft.

摘要： A sealing assembly, particularly adapted for use with an electrochemical grinding machine, for permitting relative radial oscillation and/or axial reciprocation between a spindle housing and a hood. The hood is provided with an elongated opening therein through which passes the spindle housing, the elongated opening permitting the spindle housing to radially oscillate. The seal assembly comprises a stationary seal means which is in sealing engagement with the hood and surrounds the opening therein. A movable seal means is in surrounding sealing engagement with the spindle housing. Said stationary and movable seal means are slidingly and sealingly interconnected.
