摘要： A drive shaft has a central tubular portion formed of a polymer composite with imbedded fibers. It extends between a first end and a second end. The central tubular portion has an outer peripheral surface. There is at least one ring on the outer peripheral surface of the central tubular portion. A method of repairing a composite material tube includes the steps of (a) identifying a damaged area on a composite tube, and (b) placing a patch on a surface of the tube and over the damaged area.

摘要： A transmission series has a first transmission and a second transmission. The first transmission and the second transmission each have a respective input shaft, a housing, a supporting structure fixed in the housing, and at least two bearings by means of which the input shaft is mounted rotatably in the respective supporting structure. The at least two bearings of the first transmission are of the same first design and the at least two bearings of the second transmission are of the same second design that is different from the first design. The supporting structures of the first and second transmissions are designed identically.

摘要： The method can include: monitoring a current value of a rate of reduction of torque of the shaft; providing a threshold value for the rate of reduction of torque of the shaft; and generating a signal indicative of the shaft shear event when the current value exceeds the threshold value.

摘要： A metal sleeve including a metal body which surrounds an inner channel running between a proximal and a distal opening. The inner channel has at least one groove set back into the metal body, running in the longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge. The proximal front edge of the groove is produced by impact extrusion.

摘要： A forced induction device (100) includes: a rotor (1) which includes a turbine side shaft portion (11), a compressor side shaft portion (12), and a connection shaft portion (13) connecting these to each other; a turbine side bearing (5) which supports the turbine side shaft portion (11); and a compressor side bearing (6) which supports the compressor side shaft portion (12). A rigidity of the connection shaft portion (13) is lower than that of the turbine side shaft portion (11) and the compressor side shaft portion (12) so that a node in a mode shape at each critical speed involving with an operating rotational speed region of the rotor (1) is located between the turbine side bearing (5) and the compressor side bearing (6).

摘要： A joint structure includes a first member configured to be connected rotatably to a mating member, and a second member configured to be connected rotatably to an actuator for driving the mating member. Each of the first and second members has one or more ridge portions that extend circumferentially along an outer peripheral surface. The joint structure further includes a core shaft connecting the first member and the second member, and a covering member provided tightly thereon to cover the core shaft, the one or more ridge portions of the first member, and the one or more ridge portions of the second member.

摘要： A structure includes a transmission axle rotatably mounted at a center of a housing. The transmission axle includes a sun gear mounted thereon. An internally-toothed ring track is fixed to an inner circumference of the housing. A planetary gear set is arranged between the sun gear and the internally-toothed ring track. The planetary gear set includes a plurality of stepped planetary gears arranged around the sun gear for self-spinning and orbiting around the sun gear. Each stepped planetary gear includes a first toothed portion meshing with both the sun gear and the internally-toothed ring track and a second toothed portion rotatable in unison with the first toothed portion. An output member is fit over the planetary gear set and includes an inner circumference formed with an internal toothed circumference meshing with the second toothed portion of each stepped planetary gear.

摘要： To provide a method of manufacturing a shaft for a steering device, the shaft including a spline shaft part to be coupled with an input shaft, a stopper part to be coupled with an output shaft, and an intermediate shaft part that couples the spline shaft part with the stopper part. The method includes: a step of forming a hole part recessed in an axial direction from one end of a pillar-shaped material by forging; and a step of pressing the material in which the hole part has been formed into a die to perform drawing in a radial direction on a portion of the material at which the spline shaft part and the intermediate shaft part are formed, and prolonging a length along the axial direction of the hole part at the same time by forging.

摘要： A transfer case includes a primary shaft, a secondary shaft radially offset from the primary shaft, and a torque transfer mechanism. The primary shaft includes a central channel and an inclined fluid channel. The torque transfer mechanism is configured to selectively transfer torque from the primary shaft to the secondary shaft, and includes a primary sprocket coupled to the primary shaft for transferring torque to the secondary shaft. The inclined fluid channel is associated with the primary sprocket, and includes an outlet that axially overlaps the primary sprocket.
