Patent number: 6880830Abstract: A sealing device for sealing off an opening between a shaft and a grease-lubricated split bearing housing comprises two halves divided by a diametrical cut and each having a main body arranged in a circumferential groove in the bearing housing opening. The sealing device is provided with sealing lips spaced apart from each other and forming an intermediate grease reservoir, and reinforcing portions arranged between the main seal body and the sealing lips to facilitate sealing engagement between the sealing lips and a shaft when an upper bearing housing half arranged with the upper seal half is mounted onto the shaft while the shaft is resting in a lower bearing housing half arranged with the lower seal half.Type: GrantFiled: September 6, 2002Date of Patent: April 19, 2005Assignee: SKF Mekan ABInventors: Henrik Olsson, Jörgen Stendahl

Patent number: 6549134Abstract: Temperature monitoring device for monitoring or controlling the temperature of an object, and preferably indicating and/or recording abnormal temperature variations of the object includes a housing having a contact portion for contacting the object, a sensing member in heat transferring contact with the contact portion for emitting signals representative of the object temperature, a control device that receives signals from the sensing member and actuates an indicator, a power source connectable to the sensing member, the control device and the indicator, and a switch biased to interrupt the power supply to the sensing member, control device and indicator. A portion of the housing is movable between a first position where the switch interrupts the power supply and a second position in which the housing portion urges the switch to the power supply position.Type: GrantFiled: May 3, 2001Date of Patent: April 15, 2003Assignee: SKF Mekan ABInventors: Sture Östling, Uno Axelsson

Patent number: 6428257Abstract: A locking nut includes a threaded main bore for receiving a threaded portion and a number of oblique bores in each of which is positioned a locking pin having a forward end for engagement against the threaded portion. The oblique bore and the associated locking pin have a common longitudinal axis extending at generally the same angle to the axis of the threaded main bore as one of the flanks of the thread of the threaded main bore so that the forward end of the locking nut has at least one flank generally parallel to the longitudinal axis and lying parallel to the portions of the one flank of the threaded main bore adjacent the inner end of the oblique bore. Each locking nut is generally cylindrical and possesses an outer surface that is grooved or serrated to facilitate insertion of the locking nut into the respective oblique bore.Type: GrantFiled: February 9, 2001Date of Patent: August 6, 2002Assignee: SKF Mekan ABInventors: Sture Östling, Uno Axelsson

Patent number: 6375383Abstract: An attachment device for arresting a machine member having a substantially cylindrical bore on a cylindrical shaft includes first and second sleeve members adapted to be positioned in a space between the outer surface of the shaft and the inner surface of the bore in the machine member. The two sleeve members have mating, cooperating taper surfaces in the form of a plurality of saw-tooth-shaped axially tapering sections that face one another. At least one of the sleeve members is movable for displacement relative to the other sleeve member to change the radial size of at least one of the sleeve members. The end edge of the first sleeve member projects axially beyond an adjacent end edge of the second sleeve member for receiving an external pushing force causing the first element to be displaced relative to the second element to cause the relative displacement of the sleeve members. The opposite end edge of the second sleeve members engages a stop that may be formed on the machine member.Type: GrantFiled: May 11, 2000Date of Patent: April 23, 2002Assignee: SKF Mekan ABInventors: Sture Östling, Uno Axelsson

Patent number: 6152604Abstract: A bearing unit having a sealed single-row deep-groove ball bearing. The sealed single-row deep-groove ball bearing includes an outer race ring with a sphered outer envelope surface, a housing with a sphered bore for accommodating the bearing, an inner race ring with a taper bore, and a correspondingly tapered clamping sleeve provided in the bore of the inner race ring and having a flange provided on at least one side of the bearing. The flange has at least one bore, and at least one tightening device for causing a force on the bearing inner race ring for displacing the inner race ring along the clamping sleeve thereby causing a clamping effect between the inner race ring and the sleeve and between the sleeve and a shaft on which the bearing unit is mounted. The bore of the flange includes a threaded through-bore extending at an acute angle with respect to an axial direction of an inner envelope surface of the sleeve.Type: GrantFiled: June 25, 1999Date of Patent: November 28, 2000Assignee: SKF Mekan ABInventors: Sture Ostling, Krister Hornfeldt, Uno Axelsson

Patent number: 5454674Abstract: A lock nut includes a nut body (10) having outer (12) and inner (14) circumferential surfaces. The inner surface (14) defines a screw-threaded axial through-hole that can be mounted on an externally threaded shaft. A plurality of blind bores (18) is formed in the nut body (10), each blind bore extending radially inwardly from the outer surface. Those blind bores (18) terminate short of the inner surface so that a plastically displaceable part (20) of the nut body remains between each blind bore and the inner surface to close-off a radial inner end of the blind bore (18). Locking screws (30) are mounted in respective blind bores (18). By tightening the locking screws (30), the displaceable portions (20) are pressed against the externally threaded shaft to frictionally grip the shaft.Type: GrantFiled: August 18, 1994Date of Patent: October 3, 1995Assignee: SKF Mekan ABInventor: Arne Eriksson

Patent number: 5330284Abstract: A device for mounting and/or dismounting a bearing on a shaft incorporating a tapered clamping sleeve between bearing and shaft and an arrangement for mutual axial displacement of the bearing and clamping sleeve in at least one axial direction, which arrangement incorporates at least one wedge-pointed screw arranged, when being screwed in towards the shaft to cause a mutual displacement in axial direction between the clamping sleeve and the bearing by wedge action. The bearing is situated in a surrounding sleeve-shaped member significant axial space beside the bearing at least on one side. The arrangement for displacement of bearing incorporates at least one radial flange, axially affixed to the clamping sleeve. The wedge-pointed screw is arranged to be screwed in substantially radially through holes in the bearing housing, for exerting the axial wedge force between the flange and an inner race ring of the bearings.Type: GrantFiled: March 25, 1993Date of Patent: July 19, 1994Assignee: SKF Mekan ABInventor: Stig Persson
