Abstract: A clamping ring for use e.g. as a support around a jointing sleeve during explosion welding consists substantially of two preferably equal ring halves (1,2) connected to each other over slots (3) limited by flanges (4,5) comprising surfaces (6,7) which form an angle (.alpha.). The surfaces co-operate with opposing surfaces (10,11) on an annular clamping member (9) which enclosed the flanges. Means, e.g. screws (12), are provided for bringing about a wedging action by displacing of the clamping member in relation to the clamping ring, thereby varying the bore circumference of the clamping ring. The force uniting the clamping ring halves is completely taken up by the clamping member (9) and does not stress the screws (12).

Abstract: In a freewheel mechanism with a number of blocking members arranged between raceways on two elements, one raceway is arranged on a body which is co-operating with one of the elements and is turnable thereon. The circumference of the body is variable for varying the distance between the raceways. The variations can take place because the body is elastically deformable radially and by tightening and releasing a threaded portion between the body and the element, the thread flanks thereby acting as wedges. The purpose of the arrangement is to avoid jamming of the freewheel by the blocking members upon reversal of the direction of rotation when the blocking members are in blocking position. The unwanted torque developed during jamming of the freewheel releases the tightened thread joint between the body and the element, whereby the circumference of the body and the distance between the raceways of the freewheel is increased so that the blocking members are released.

Abstract: The invention concerns a nut provided with a locking element (4, 5, 6, 7), which by e.g. a screw (8, 9, 10, 11) can be urged radially against a screw thread. In order to provide a self-contained and easily releasable nut the locking element is arranged in a recess which, together with the element, is so arranged that at least a part (12, 13, 14, 15) of the element is deformed elastically when the element is moved against the screw thread. Thereby the element springs out of contact with the thread when the screw (8, 9, 10, 11) is released.

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.

Abstract: A device for fastening e.g. a bearing ring on a shaft comprises a clamping sleeve and a clamping member co-operating with the sleeve. The clamping member and the sleeve contact each other over wedge-shaped surfaces. The sleeve surfaces intended for contacting the bearing ring and the clamping member have such shape that the clamping force acts essentially on that part of the sleeve which co-operates with the clamping member, and no appreciable axial displacement takes place between the sleeve and the bearing ring. Thereby the bearing ring keeps its shape and position during mounting.

Abstract: In a motion transmitting mechanism comprising a linearly moveable member (3) operating to and from an end stop, a compressible spring (9) is arranged between the linearly moveable member (5) and a supporting surface (10), whereby the spring is compressed when the member (5) approaches the end position and gives a force on the member (5) directed away from the supporting surface when the member is in its end position.

Abstract: In a device with a double-row angular contact bearing the outer raceways are arranged in elements (4,5) which are axially displaceable in relation to each other. Prestressing or play of the bearing is determined by an elastic ring (7) situated in a space delimited by opposing surfaces connected to the respective elements, whereby the axial bearing play decreases when the distance between the opposing surfaces increases.

Abstract: A device for sealing a spherical rolling bearing comprises two annular sealing bodies (4, 5) arranged on the respective bearing rings and divided by a gap (6) with spherical opposing surfaces. A further sealing washer (9) is provided in recesses (7, 8) in the sealing bodies (4, 5) and delimits a space (10) in connection to the gap (6). The washer (9) is fixed in one sealing member (4) and is provided with a sealing lip (11) contacting a spherical surface of the other sealing body (5). The device gives a good sealing effect also when the rings of the bearing are skewed in relation to each other.

Abstract: An element intended for connection to a shaft arranged in a bore in the element comprises two elastically deformable portions created by providing slots perpendicular and parallel to the axis of the bore, respectively. The portions each comprise a part of the wall of the bore and are arranged symmetrically with respect to the bore. Screws are used for deforming the portions so that a shaft situated in the bore is clamped to the element.

Abstract: The invention refers to a hub bearing unit for vehicles, trailers and the like incorporating two rows (4) of rolling bodies with a common outer ring (5). On the outer race ring (5) is arranged a flange (6) for mounting the unit and arranged symmetrically relative to the rows of rolling bodies (4). The flange (6) is provided with attachments holes (7) and lugs (8) adjacent these, whereby the side surfaces of the lugs (8) are in level with the side (10) of the outer race ring (5), which shall engage the attachment surface of the vehicle, the trailer or the like.

Abstract: The invention relates to a device for performing rotational movement and comprises a rotatably element such as a cog-sector (3) or the like, arranged in a housing (1). The sector can easily be connected to rotatable machine elements of various kinds by being provided with an easily exchangeable coupling element (7) which can be displaced axially through a bore in the sector and through two bearings (8, 9) and be detachably fastened to the cog-sector by e.g. screws (14, 15) provided in threaded bores in the sector and abutting radially directed support surfaces in recesses in the element (7) between the bearing surfaces of the bearings (8, 9).

Abstract: A nut which is lockable on a threaded element comprises two annular parts (1, 2) connected by preferably resilient members (5). Locking takes place by tightening a screw (6) arranged in a threaded bore in one nut part and abutting against the other nut part. During tightening of the screw, the parts (1, 2) are displaced and/or skewed in relation to each other whereby locking takes place on the thread.
