摘要： A balance shaft includes an unbalanced shaft (3) comprising a bearing journal (8, 9), the periphery of which is merely partially cylindrical. The cylindrical partial periphery (10) of the bearing journal is oriented toward the shaft imbalance. The balance shaft also includes a needle roller cage assembly (15); and a bearing ring (13), which extends around the bearing journal, lies against the cylindrical partial periphery and forms the inner raceway of the needle roller cage assembly. The cage (27) of the needle roller cage assembly is designed to run on the end faces of the bearing ring axially on both sides by means of radially inwardly extending projections.

摘要： A planet gear includes an annular planet gear rim having a constant inner radius along a complete axial length and an outer radius defined as the radial distance to the root of the gear teeth. The annular planet gear rim further has an average rim radius defined at a halfway point between the constant inner radius and the outer radius. The average rim radius and the rim thickness define a ratio including values in a range from and including about 4 to and including about 9. A gear assembly and turbomachine including the planet gear are disclosed.

摘要： A roller of a roller bearing providing a hollow bore in which a load cell is arranged, for measuring a radial load acting on the roller. The load cell is mounted to the roller bore in a non-fixed manner and includes one or more cantilever beams that extend in an axial direction of the roller. A contact element is provided on each cantilever beam. Each element further bears against a surface of the roller bore. At least one sensor is provided on each cantilever beam for measuring bending thereof, due to deflection of the beam in a radial direction perpendicular to the axial direction.

摘要： The invention includes a sensor mounted in a through-hole formed in the center of a roller of a roller bearing device, a recording device that records detection signals from the sensors, and an installation jig for installing the recording device in the roller. The installation jig passes through the through-hole, and has a first engagement portion that engages with one axial end portion of the roller from an outer side in an axial direction, and a second engagement portion that engages with the other axial end portion of the roller from the outer side in the axial direction.

摘要： A wheel assembly for a luggage item and a luggage item. The wheel assembly may include a housing for operably coupling the wheel assembly to a luggage item. The wheel assembly may also include a wheel support rotatably coupled to the housing and having a first axis of rotation. The wheel support may be coupled to a wheel member having a second axis of rotation. A friction reduction member may be positioned between the housing and the wheel support to facilitate the relative rotation therebetween. The wheel support may include an underside defining in part a conical shape.

摘要： A roller seating for swivel motions includes an outer ring, an inner ring and roller rolling in between which are inserted individually between spacers of a flectionally elastic cage. On at least one end of the spacers, one or more projections directed radially outward and/or radially inward have been formed which face, radially and/or axially, a revolving shoulder surface of the outer ring or the inner ring. In order to keep the play of the rollers between the spacers on the circumferential side as small as desired, each projection of the cage is arranged in such manner that it pushes against the circumference of the corresponding shoulder surface of the outer ring or the inner ring and brings the holding surfaces of the spacers against the rollers due to the elastic deformation of the cage.

摘要： A thrust roller bearing cage having pockets for accommodating rollers includes an inner annular portion and cage bars that extend in a radial manner from a radially outer edge of the inner annular portion so as to separate the pockets from each other in a circumferential direction. The inner annular portion has a first axial end surface and a second axial end surface. The first axial end surface has an oil passage groove for guiding lubricating oil to the pockets. The second axial end surface is recessed more than the first axial end surface in an axial direction of the inner annular portion so as to form a recessed portion that communicates with the oil passage groove. The whole of a region of the first axial end surface that is located radially directly inside the cage bars is located radially outside the second axial end surface.

摘要： This invention relates to cutting tools used to machine materials to produce new surfaces and chips of removed material. Embodiments of this invention allow round rotating cutting inserts to be used in a more economical way, with improved accuracy, with improved sealing, and with greater ease of use. The rotary support device and cutting inserts may be used in either radial or tangential mounting types of cutters. It also provides a built-in, fully sealed means of fine adjustment of the cutting insert that is useful in some applications.
