摘要： A method of lubricating a coupling shaft of a gear pump includes communicating lubricant from a first gear stage along a first splined end section of the coupling shaft and through a first slot in a first radial shoulder of the coupling shaft, and also communicating lubricant from a second gear stage along a second splined end section of the coupling shaft and through a second slot in a second radial shoulder of the coupling shaft. The first radial shoulder is axially spaced from the second radial shoulder by an axial distance SA along an axis of rotation of the coupling shaft. The first and second slots each define a lowermost radial dimension SR from the axis of rotation, with a ratio SR/SA of 0.25-0.77.

摘要： A motor vehicle steering system is disclosed. The system includes a steering spindle consisting of spindle members which are non-rotatably connected to one another. One end of a spindle member has a spline shaft profile and is introduced into a sleeve-like intermediate piece which is arranged on the other spindle member and, on the inner periphery, has a negative-shaped spline shaft profile with respect to the spline shaft profile such that the spindle member is plug-connected to the intermediate piece. In order for the spindle members to be able to be connected to each other with minimal effort even in the event of visual inaccessibility, a circumferential guide contour pointing toward the intermediate piece is formed on the spindle member. The guide contour is upstream of the spline shaft profile toward the intermediate piece and is perforated by grooves of the spline shaft profile to form convex guide segments.

摘要： A wheel supporting device includes: a hub unit that has a rotary ring having a first spline on its axially inner end face; and a joint that has an outer ring having a second spline, meshing with the first spline, on its axially outer end face. At least one projection included in a plurality of projections of the first spline projects in the axial direction by a larger amount than the remaining projections of the first spline. When a crest of the at least one projection contacts a crest of one of projections of the second spline, a play is caused between the rotary ring and the outer ring due to the at least one projection that works as a fulcrum.

摘要： A rotation transmitting apparatus includes a first shaft on which multiple external teeth are formed so as to be arranged in a circumferential direction, and a second shaft in which multiple internal teeth are formed so as to be arranged in the circumferential direction, the second shaft being fitted to the first shaft so as to be slidable relative to the first shaft in the axial direction and so as to be engageable with the first shaft in a rotational direction through the use of the external teeth and the internal teeth. A protrusion is formed on the tooth flank of one of the external tooth and the internal tooth, the protrusion being projected toward the corresponding tooth flank of the other of the external tooth and the internal tooth. The protrusion is made of a resin that is more elastically deformable than the tooth flank.

摘要： A spline structure, in the form of an aeronautical brake drive bar, has wheel attachment points at its ends for engaging a wheel rim. Each wheel carries a regularly spaced series of these drive bars for engaging friction discs carried by the wheel hub. The main body of each brake drive bar is formed from titanium internally reinforced by composite blocks each comprising a bundle of silicon carbide fibers contained in a matrix that is diffusion bonded within the main body. Other spline structures can be formed in a similar manner.
