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.

The present disclosure relates to coupling assemblies for drive shaft assemblies. The coupling assembly comprises a first portion and a second portion which are configured to couple to one another such that the second portion is capable of rotationally driving the first portion about an axis of rotation. The first portion is provided with a first magnet and the second portion is provided with a second magnet. The first and second magnets are arranged to repel each other such that the first and second portions are biased away from each other in an axial direction that is parallel to the axis of rotation.

A coupling for allowing torque transmission between a first and second shaft, the coupling comprising: a cup-shaped portion provided at a first end of said first shaft and a first end of said second shaft being positioned within said cup-shaped portion; and said coupling further comprising a biasing means positioned between said first and second shafts, such that said biasing means is in contact with both of said first and second shafts. A shaft system can include the first coupling in combination with a third shaft and a second coupling that is provided between the third shaft and either a second end of said first shaft or a second end of said second shaft. The second coupling is identical to the first coupling.

A spline assembly, including a spline shaft having a first end and a second end, wherein the first end is splined to engage a spline receiver of a primary drive system and includes a substantially spherical alignment head, wherein the spherical alignment head comprises an expendable hydrocarbon material that is caused to melt by operation of the primary drive system over time.

A gas turbine shaft assembly comprises first and second axially mating shafts. The first shaft has a circumferential array of splines configured to mesh with a corresponding circumferential array of splines on the second shaft. The first shaft defines at least one axially extending slot aligned with one of the splines on the first shaft. The second shaft has at least one radial projection aligned with one of the splines on the second shaft. The engagement of the radial projection with the slot provides angular correspondence between the splines of the first and the second shafts prior to axial engagement of the splines.

A drive transmitter that is applicable to an image forming apparatus includes a first coupler, a second coupler, and reinforcing ribs. The first coupler is mounted on an axial end of a first rotary shaft and is provided with extensions. The extensions extend in an axial direction of the first coupler and are arranged at intervals in a rotation direction thereof. The second coupler is mounted on an axial end of a second rotary shaft and is provided with contact parts to which the respective extensions contact between the first rotary shaft and the second rotary shaft upon drive transmission. The reinforcing ribs are provided to the respective extensions and reinforce the respective extensions.

A torque transmitting shaft includes a first member and a second member. The first member extends along an axis and has an inner surface extending between a first end and a second end. The inner surface defines a plurality of first engagement elements disposed proximate the first end. The second member extends along the second axis and has a first end portion and an intermediate portion extending from the first end portion. An end of the intermediate portion is fixedly attached to the second end. The first end portion has a first spline portion and each member of the first spline portion is received within corresponding engagement elements of the plurality of first engagement elements.

A device for joining an engine damper and a transmission clutch, may include connecting plates disposed at predetermined positions on the engine damper to be able to transmit power and covering protrusions formed on an input portion of the transmission clutch to be able to transmit power to the protrusions.

A gas turbine shaft assembly comprises first and second axially mating shafts. The first shaft has a circumferential array of splines configured to mesh with a corresponding circumferential array of splines on the second shaft. The first shaft defines at least one axially extending slot aligned with one of the splines on the first shaft. The second shaft has at least one radial projection aligned with one of the splines on the second shaft. The engagement of the radial projection with the slot provides angular correspondence between the splines of the first and the second shafts prior to axial engagement of the splines.

A splined coupling comprises a radially inner shaft and a radially outer shaft having a cavity for receiving the inner shaft. First splines are provided on a radially outwardly facing surface of the inner shaft. Second splines are provided on a radially inwardly facing surface of the cavity of the outer shaft. The first splines are slidably engaged with the second splines. At least one biasing element, for example a diaphragm is arranged to act between the radially inner and radially outer shafts for locating the first splines in a desired axial position relative to the second splines and to provide a biasing force resisting the axial movement of the first splines relative to the second splines upon relative axial movement of the inner and outer shafts.
