  • Patent number: 4768993
    Abstract: A device for elastic interconnection of two rotatable shafts consisting of a first sleeve intended to be connected to a first shaft end. The sleeve has a radial flange and a cylindrical, annular portion connected to the periphery of the flange. A second sleeve is intended to be connected to a second shaft end and to be surrounded by said cylindrical portion. A number of elastically deformable spherical elements are arranged in opposing recesses in said second sleeve and cylindrical portion and distributed around a shaft end. The recesses in the cylindrical portion are arranged in the end surfaces of plugs and provided with external threads. The plugs by being turned are displaceable in threaded bores provided radially in the wall of the cylindrical part. The outer end surfaces of the plugs are provided with diametrical grooves and the cylindrical portion is provided with a diametrical groove. The diametrical grooves and the peripheral grooves define an annular groove.

  • Patent number: 4598443
    Abstract: A device for providing a clamping joint comprises two elements (1,2) with complementary threads, each having a flange constituting a clamping surface. Clamping takes place upon relative axial displacement of the elements (1,2) which can be brought about by screws (4) arranged axially in bores in a flange (5) on one element. In order to prevent accidental disengagement of the elements, at least one of the threads adjoins at one end to a part (6) which is wedged against an opposing thread flank when the elements (1,2) are rotated in relation to each other over a predetermined end position.

  • Patent number: 4226571
    Abstract: A pressure oil injector assembly characterized by novel features of construction and arrangement providing easy and quick mounting and dismounting and which has good transportability comprising an attachment and connecting member with connections for a pump housing of a pressure medium pump and a pressure pipe. The mounting arrangement is such that the high pressure side of the pump in in communication with the pressure pipe. The pump housing and pressure pipe are connected to the attachment and connecting member by means of threaded dowels which seat in threaded bores in the attachment and connecting member which are opposed to each other and spaced by a chamber or aperture. In the principal embodiment, a manometer seats in the aperture with a certain amount of play and is supported in a firm position between the inner terminal ends of the dowels.

  • Patent number: 4159828
    Abstract: A device for sealing the space between two surfaces comprising an elongated body portion made of a flexible, resilient material such as rubber. The body portion engages in a recess in one of said surfaces. The sealing device further includes at least two rigid plate members seating in a recess in the body portion and having a portion projecting therefrom defining a channel and a sealing member mounted in said channel and projecting therefrom to engage the other of the sealing surfaces to be sealed.

  • Patent number: 4136914
    Abstract: A bearing housing characterized by novel features of construction and arrangement providing an adjustable bearing seat. The housing has a longitudinal slot and mounting portions protruding at each side of the slot. Each of the mounting portions is provided with a support surface confronting a base which in the unloaded condition is disposed at an angle relative to the base. The angular relationship of the mounting portions to the base can be selectively varied by pressing the mounting portions against the base by fastening elements engaging through openings in the mounting portion and engageable in the base. The housing is elastically deformable and when so adjusted the width of the slot is selectively varied and thereby the diameter of the seat can be adjusted.

  • Patent number: RE33453
    Abstract: A bearing housing (3) encloses a bearing (2) for a shaft (1). The bearing is mounted on the shaft by a clamping sleeve (4) with a longitudinal slit and two flanges (5,6) one on each side of the bearing. The flanges, which are axially fixed on the sleeve, are parts of mounting and dismounting means for a bearing. The bearing space is sealed by sealing members which surround the flanges .[.and.]..Iadd., In a preferred embodiment, the sealing members .Iaddend.have lips (12,13) contacting the outer surfaces of said flanges. Resilient sealing rings (10,11) are arranged between the flanges and the inner ring of the bearing. The sealing arrangement allows the use of a slitted clamping sleeve and axial displacement of the bearing on the shaft (1) during mounting.
