    摘要： A spline coupling comprises a male spline member having male spline teeth and a female spline member having female spline teeth complementary to and engaged with the male spline teeth. One or more of the female spline teeth has a tooth height lesser than a tooth height of another one or more of the female spline teeth. The tooth height of the one or more of the female spline teeth is defined by a top land surface of the one or more of the female spline teeth. The tooth height of the other one or more of the female spline teeth is defined by a top land surface of the other one or more of the female spline teeth. A drainage hole in the top land surface of the one or more of the female spline teeth passes through the one or more of the female spline teeth.

    摘要： A wiper arm for supporting a wiper blade includes a wiper arm head comprises a recessed splined cup portion having a plurality of angularly adjacent teeth about the internal circumference of the cup portion wherein the cup portion includes a slot. A complementary drive shaft includes a splined head having teeth for mating engagement with the teeth in the wiper arm head. In order to facilitate the alignment therebetween, an integral alignment key is received in the axially aligned slots. The alignment key further includes a lower notched end which abuts against a bottom radial lip of the splined head to prevent the key from moving axially in the slots. As such, the key and the splined head include complementary formations preventing the key from accidentally falling out of the slots.

    摘要： A locking artificial tree trunk including a first generally cylindrical, hollow trunk portion including an upper end, the upper end defining a notch, and a second generally cylindrical trunk portion including a body portion, a lower end having an insertable portion, and an upper end. The locking artificial tree trunk also includes a coupling mechanism having a body portion and an upper portion having a tab, and defining a channel for receiving the insertable portion of the lower end of the second trunk portion. The body portion is inserted substantially into the upper end of the first trunk portion with the tab of the upper portion aligned with the notch, thereby preventing rotation of the coupling mechanism within the upper end of the first trunk portion.

    摘要： A rotational coupling arrangement, such as for use with a vehicle, is provided. The coupling arrangement includes a first rotational component have at least one straight groove, the groove having a sidewall. A second rotational component is coupled to the first rotational component, the second rotational component having at least one projection. The at least one projection having a linear profile between a first end and a second end, the at least one projection having a first section adjacent the first end and a second section adjacent the second end. The first section is sized to define a first gap between the first section and the sidewall, the second section being sized to define a second gap between the second section and the sidewall. The second gap is smaller than the first gap.

    摘要： A shaft coupling assembly retains a shaft end in a coupling element channel using a fastener inserted through a coupling element bore and a recess in an engagement segment of the shaft end to engage the coupling element to exert a clamping force on a shaft interface of the engagement segment. A projection having a smaller cross section than that of the shaft interface extends axially from the engagement segment and has sufficient length to protrude into the bore to interfere with fastener engagement prior to engagement of the shaft interface in the channel. A projection upper surface further interferes with the fastener bore to prevent engagement of the fastener when the shaft end has been engaged to the channel but not inserted to an installed position. The upper surface may be defined by an arcuate portion of the projection which may have a teardrop shaped cross section.

    摘要： A rotational assembly comprises a first shaft having a plurality of circumferentially arranged axially extending outer splines on an outer surface thereof and a second shaft having a plurality of circumferentially arranged axially extending inner splines on an inner surface of an axially extending shaft recess. The first shaft is located with the shaft recess such that the outer splines are engaged with the inner splines. At least one biasing element is also provided which is arranged to rotationally bias the first and second shafts towards one another such that the driving faces of the inner and outer splines are forced together.

    摘要： A driver (3) for the transfer of torque and rotation from a rotation chuck (5) to a drill steel (2), whereby the cross-section of the driver (3) is limited outwards by curves, in particular by arcs, united to form a closed FIG. 6 that can be approximately described as a polygon, and limited inwards by splines (4). The FIG. 6 comprises four sides (7) and four corners (8). The splines (4) comprise a number of spline teeth (10), the number of which is divisible by four.
