A torque transmission device includes a shaft which has shaft teeth around its outer circumference, a hub which has hub teeth on an inner circumference, wherein the hub is arranged on the shaft in such a way that the shaft teeth and the hub teeth mesh with one another in order to transmit torque. The torque transmission device furthermore includes at least one spring element which passes entirely through the hub and is supported on the shaft and the hub and exerts a spring force on the hub and the shaft, wherein at least a component of the spring force is directed in such a way that around the entire circumference of the shaft and hub adjacent flanks of the shaft teeth and the hub teeth are pushed together.

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.

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.

A shaft assembly includes a shaft with a first radial shoulder and a second radial shoulder. The first radial shoulder and the second radial shoulder each include at least one slot. An axial separation between the first radial shoulder and the second radial shoulder defines an axial distance SA along an axis of rotation. The at least one slot defines a lowermost radial dimension SR from the axis of rotation. A ratio of SR/SA is 0.25-0.77.

摘要:
A mounting arrangement for a drug-delivery device is proposed, the mounting arrangement comprising: a plug element with a longitudinal axis (L) and a housing part having a recess with a side wall which is adapted to receive the plug element. At least one of the plug element or the side wall of the recess are provided with a protrusion for fixing the plug element in a given position relative to the housing part by a force-fit engagement. Furthermore, a coupling assembly is proposed, the coupling assembly comprising the plug element and the housing part being mechanically coupled to each other.

In a coupling structure for coupling a shaft to a universal joint yoke, an insertion portion of a shaft is passed through an insertion hole of a universal joint yoke. An outward protrusion of a distal end portion of the shaft faces a peripheral edge of a first opening of the insertion hole across a gap in an axial direction. A fixed portion that adjoins the insertion portion is fixed to a peripheral edge of a second opening of the insertion hole by welding. An engaging portion formed on an outer periphery of the insertion portion and an engaged portion formed in an inner periphery of the universal joint yoke, which defines the insertion hole, are engageable with each other in a rotational direction with a rotation permitting gap for phase adjustment.

A spline connection apparatus includes a male spline apparatus and a female collar apparatus coupled together. The male spline apparatus includes an external spline and a plurality of first tooth spaces having spline relief portions for tool clearance extending angularly and conically into a shoulder portion and base portion of the male spline apparatus. The female collar apparatus includes and internal spline and a plurality of second tooth spaces having an internal spline relief portion for tool clearance extending angularly and conically into the counterbore engagement surface of the female collar apparatus. The external teeth of the external spline and the internal teeth of the internal are equal in length. The effective face width of the engagement is equal to the length of the external and internal teeth.

A telescopic shaft includes a male shaft having an outer circumference formed with a plurality of protruding teeth, and a female shaft having an inner circumference formed with a plurality of tooth grooves and fitted onto the male shaft. The protruding teeth and the tooth grooves are engaged such that the male shaft and the female shaft are relatively axially slidable and a rotational torque is transmittable between the male shaft and the female shaft. At least one of the male shaft and the female shaft is configured such that the radial rigidity of a portion of the at least one of the male shaft and the female shaft in an axial range of a region where the protruding teeth and the tooth grooves are engaged is lower than the radial rigidity of another portion of the at least one of the male shaft and the female shaft.
