Various disclosed embodiments include illustrative apparatuses, medical systems, and methods for attaching two dissimilar materials. In an illustrative embodiment, an apparatus includes a first rod formed from a first material and a second rod formed from a second material. The first rod includes a first end defining a cavity exposed at an end of the first rod. The cavity has a cavity length and a cavity width perpendicular to a longitudinal axis of the first rod. The cavity length is greater than the cavity width. The second rod includes a first section and a second section. The first section has a width that corresponds to the cavity width and a length that corresponds to the cavity length. The apparatus includes a bonding structure that attaches the first rod to the second rod.

A main shaft assembly of a wind turbine and method for manufacturing the same are provided. Accordingly, the main shaft assembly includes a structural/shaft body defining a cavity therein. The shaft body is configured to transmit a load of the wind turbine developed in response to the wind. An inner body is located within the cavity. The inner body is non-loadbearing with respect to the load. At least one sensor is coupled to the inner body and positioned within the cavity for detecting a deflection of the shaft body in response to the load.

A power transmission shaft has a shaft member having, on an outer peripheral surface thereof, a male spline; a cylindrical member having, on an inner peripheral surface thereof, a female spline; and a seal member provided in a pressed state between an outer peripheral seal surface formed on the outer peripheral surface of the shaft member and an inner peripheral seal surface formed on the inner peripheral surface of the cylindrical member. The cylindrical member is spline-engaged with the shaft member by one end side of the shaft member being inserted into the cylindrical member from an other end side of the cylindrical member. Axial direction shock is absorbed by sliding of the splines. The outer peripheral seal surface is positioned at the other end side with respect to the male spline, and the inner peripheral seal surface is positioned at the other side with respect to the female spline.

A split shaft is disclosed. The split shaft includes a proximal shaft section having a first proximal shaft end and a second proximal shaft end. The first proximal shaft end is configured to couple to the first machine arrangement. The split shaft further includes a distal shaft section having a first distal shaft end and a second distal shaft end. The first distal shaft end is configured to couple to the second machine arrangement. The second distal shaft end is configured to engage with the second proximal shaft end to convey the drive power from the first machine arrangement to the second machine arrangement. The second proximal shaft end includes a first indicator, and the second distal shaft end includes a second indicator. Alignment of the first indicator and the second indicator conveys timing for the drive power.

A component includes a base formed of a majority of a first metallic element and a shell adhered to the base. The shell includes an inner portion having an inner surface contacting the base, an outer portion having an outer surface, and an intermediate zone connecting the inner portion to the outer portion. The shell is formed of a multi-element transition material, where the multi-element transition material includes a majority of a second metallic element at the inner surface and a majority of a third metallic element at the outer surface. The intermediate zone includes both the second and third metallic elements. Each of the first, second, and third metallic elements are different from one another. The component may be an automotive shaft. A method of forming the component may include depositing first and second powders on the base to form the inner and outer portions and the intermediate zone.

A steering shaft assembly includes a male shaft having a plurality of splines formed thereon, each of the splines terminating at a spline end, wherein each of the spline ends form an angle of about 90 degrees relative to a longitudinal direction of the splines. The steering shaft assembly also includes a female shaft including a plurality of stakes located proximate an end of the female shaft, the stakes retaining the male shaft at an interface between the stakes and the spline ends.

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.

The embodiments of the present disclosure provide a shaft structure of a motor, comprising a housing, a stator disposed inside the housing, and a rotor rotatably disposed inside the stator. The stator may comprise a stator core and a coil wound around the stator core, and the rotor may comprise a rotor core and a rotational shaft coupled to the rotor core. The rotational shaft may comprise a plurality of adjusting portions formed on an outer circumferential surface of the rotational shaft to align a center of gravity of the rotor with a center of the rotational shaft.

An extendable shaft includes: an inner shaft including a plurality of external teeth; an outer shaft including a plurality of internal teeth that slides relatively to the external teeth; and a resin layer covering the external teeth. The pressure angle of the external teeth is different from the pressure angle of the internal teeth.
