Abstract: A propeller shaft (1) that is a power transmission shaft has a shaft member (2) as a tubular body made of iron-based metal and a balance weight (3) made of iron-based metal and welded to an outer peripheral surface of this shaft member (2). At least a part of the balance weight (3) of the propeller shaft (1) is covered with a sacrificial metal coating (4) made of sacrificial corrosion prevention material that contains metal whose ionization tendency is higher than that of metal forming the shaft member (2). With this, it is possible to suppress local progression of corrosion at a periphery of the balance weight (3) and improve durability of the propeller shaft (1).

Abstract: A balancing weight is disclosed. The balancing weight is engageable in a hole defined in a rotor, the hole having a predetermined cross-sectional dimension. The balancing weight comprises: a head having a predetermined weight, and a shank extending axially from the head. The shank includes at least two portions expandable in a direction transverse to a hole engagement direction between a first position in which a cross-sectional dimension of the shank is less than the predetermined cross-sectional dimension of the hole and a second position in which the cross-sectional dimension of the shank is greater than the predetermined cross-sectional dimension of the hole in the rotor. A method for installing a balancing weight to an engine rotor is also disclosed.

Abstract: An automatic dispenser for balancing weights including a transport section and a cutting section. The transport section contains a transport roller with a plurality of teeth at its circumferential outer surface generating friction to a belt of balancing weights to transport this belt to the cutting section. Such belt contains a plurality of individual balancing weight segments. The cutting section has an arc shaped belt guide for forming the belt of balancing weights to a curve thus opening at least one gap between neighboring balancing weight segments. The cutting section has a knife movable from a first side of the belt of balancing weights to its second side, to separate the belt of balancing weights at a gap between two individual balancing weight segments.
