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 method of forming a balanced rotor blade assembly includes measuring a weight of a plurality of sub-components of the rotor blade assembly excluding a core. A configuration of a core of the rotor blade assembly is determined. In combination, the core and the plurality of sub-components achieve a target weight distribution and moment. The core is then fabricated and assembled with the plurality of sub-components to form a rotor blade sub-assembly.

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 fan of the invention includes an impeller having a plurality of blades and rotating around a rotation axis, and at least one balance weight having at least one claw portion and attached to the impeller to correct the center of gravity of the impeller. The impeller has a circumferential convex portion formed along the circumferential direction, and on which the claw portion is hooked to restrict a range of movement of the balance weight in the radial direction of the impeller, and at least one radial concave-convex portion formed along the radial direction, and on which the claw portion is hooked to restrict the range of movement of the balance weight in the circumferential direction of the impeller.

摘要： Balancing weights for cars have an adhesive tape with at least a first tape layer and a second tape layer, for attaching the balancing weights to a rim. The first tape layer is held in close proximity to a rim by a first adhesive layer. The second tape layer is held in close proximity to the balancing weights by a second adhesive layer. The first tape layer is stiffer and less flexible than the second tape layer, the second tape layer is softer and more flexible than the first tape layer. This allows easy removal of the balancing weights from the rim by pushing a wedge shaped tool between the first tape layer and the rim.

摘要： A shaft balancing device for insertion into a shaft including a generally flat cylindrical band having an outer surface, an inner surface and a set of two crush points thereon. A balancing weight is attached to the outer surface of the band between the set of crush points. The device is inserted into the shaft and the crush points are plastically deformed radially outward creating spring force which holds the balancing weight to the inner surface of the shaft. The band has a curved connecting portion between the two crush points having a radius of curvature slightly greater than the curvature of the shaft. The balancing weight has a radius of curvature slightly greater than the radius of curvature of the curved connecting portion and slightly less than the radius of curvature of the shaft.

摘要： A ring has a ring body with a central portion surrounding an axis and extending to first and second opposing ends separated by a split. The central portion has a first axial thickness. At least one retaining feature is formed on the ring body, the at least one retaining feature having a second axial thickness greater than the first axial thickness. An assembly and a gas turbine engine are also disclosed.

摘要： An additional weight for a wheel for ballasting a drive axle of a working machine includes a first loading disk centrally connected to the drive axle and a second loading disk connected to the first loading disk. The first loading disk has a conical abutment face for pre-positioning the second loading disk relative to the first loading disk. The first and the second loading disks form encoding formations for mutually centering on end faces which face each other and which are in engagement with each other in a connected state of the loading disks. At least one of the end faces of at least one of the loading disks forms a spacer dome. In the connected state, the spacer dome contacts an end face of the other loading disk in order to position the first and the second loading disks with respect to each other in an axial direction.

摘要翻译： 用于汽车的平衡重物具有至少第一带层和第二带层的粘合带，用于将平衡重物附接到轮辋。 第一胶带层通过第一胶粘层保持在靠近轮辋的位置。 第二带层通过第二粘合剂层保持紧靠平衡重。 第一带层比第二带层更硬并且不那么柔性，第二带层比第一带层更软和更柔韧。 这允许通过在第一带层和边缘之间推动楔形工具从而容易地从边缘移除平衡重块。
