Granted: 2005-04-15
Abstract: The invention relates to a dynamic groove bearing (9) comprising an internal bearing part (23) and an external bearing part (17) which are rotatable relatively to each other about an axis of rotation (7), a bearing surface (31, 35) of one of the bearing parts comprising two grooves for co-operation with a bearing surface (39) of the other bearing part. The groove bearing further comprises a reservoir made from a porous material for a lubricant which is present between the bearing surfaces. According to the invention, the reservoir is mounted between the two groove patterns, viewed in a direction parallel to the axis of rotation. In this manner, a uniform supply of the lubricant from the reservoir to the two groove patterns is obtained, while also the number of parts of the groove bearing is limited. In a preferred embodiment, the reservoir comprises a ring-shaped body (29) which is made from the porous material and mounted in the external bearing part. The ring-shaped body may be confined between two bearing bushes (25, 27) of the external bearing part on which the two groove patterns are present. The ring-shaped body may further comprise at least one air-vent duct (57, 59, 61, 63). The dynamic groove bearing according to the invention can be used in an electric motor (1) for driving a rotatable support (83) for an information carrier (89) in a scanning device (81), such as an optical disc player.

Abstract: The fixing consists of an elongated connecting element (1) with holes for bone anchoring screws (2). Each screw passes through a hole in the connecting element which has a circular recess at its lower end to receive the spherical head (21) of a screw. Each screw hole has an internal thread at its upper end to receive a threaded cap (3) designed to engage with the screw head and lock the screw in the required angular position. The connecting element is in the form of a plate with holes for the screws. Each of the threaded caps has a concave spherical under surface which matches the spherical outer surface of a screw head. Alternatively, the connecting element can have two screw holes linked by a slot which allows it to be adjusted before the screw is tightened. Both screw heads and caps have hexagonal sockets for an instrument to fasten and release them. Their contacting surfaces can have a low friction coating, e.g. of ceramic or diamond-carbon.
