摘要： 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).

摘要： A weight applicator including a weight applicator head and at least one actuator is disclosed. The weight applicator head is adapted to carry a wheel balance weight and has a weight application surface with a weight retaining region and a leading rotation region. The at least one actuator is coupled to the weight applicator head for manipulating the weight applicator head in at least one direction. The at least one direction has a radial component. The leading rotation region is oriented to extend radially further than the weight retaining region.

摘要： 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.

摘要： An oscillating power tool with an electric motor is provided, including an armature shaft with an armature and a fan wheel, including an eccentric arranged on the armature shaft at one end thereof, a first balancing mass for balancing an unbalance of the eccentric and possibly an eccentric bearing, being arranged in the proximity of the eccentric or the eccentric bearing, respectively, however, at an axial distance, further including a second balancing mass for balancing a couple unbalance caused by the axial distance between the eccentric and the eccentric bearing, respectively, and the first balancing weight, wherein the second balancing mass is arranged on the armature shaft at the side facing away from the eccentric or the eccentric bearing. Also a method for balancing such an electric motor is provided.

摘要： A vibration damping device is configured to reduce vibration that causes lateral flexing of an elongated member that extends along a centerline. The device includes a split sleeve co-extending with and disposed about the elongated member, and a spring that extends about the sleeve and exerts a force that biases the sleeve radially inward.

摘要： 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.

摘要： A combination vehicle tire sensor assembly and in-tire wheel balancer is adapted for residing inside a pneumatic tire mounted on a wheel rim of a motor vehicle. The combination includes a flexible mounting cable secured to the sensor assembly, and adapted for extending circumferentially within an annular space formed between the tire and wheel rim. A counterweight is secured to the mounting cable inside the pneumatic tire a spaced distance from the sensor assembly. A substantially hollow balancer belt resides inside the pneumatic tire adjacent the sensor assembly and counterweight, and defines a circumferentially-extending exterior groove designed for receiving and locating said mounting cable, and a circumferentially-extending interior cavity adapted for loosely containing a wheel-balancing medium.
