Abstract: A rotating assembly for a gas turbine engine has a balancing ring mounted to a first rotating component having a rotating unbalance about an axis of rotation. The ring is clocked at a circumferential position about the axis to counteract the rotating unbalance. A spacer is axially abutted against the first rotating component to set an axial position of the first rotating component relative to a second rotating component. The balancing ring is locked against rotation relative to the first rotating component in its circumferential position by the dual use spacer.

Abstract: A grinding apparatus includes grinding wheel side vibrational displacement calculation devices that obtain a vibrational displacement of a grinding wheel resulting from a vibration in an approaching/separating direction of the grinding wheel; main spindle side vibrational displacement calculation devices that obtain a vibrational displacement of a workpiece generated by propagation of the vibration in the approaching/separating direction of the grinding wheel; a relative vibrational displacement calculation unit that obtains a relative vibrational displacement between the grinding wheel and the workpiece based on the vibrational displacement of the grinding wheel and the vibrational displacement of the workpiece that have been obtained; a position change unit that creates, based on the obtained relative vibrational displacement between the grinding wheel and the workpiece, a position change command to change a position of the wheel spindle stock; and a processing controller that grinds the workpiece W based o

Abstract: A mixed flow turbine wheel (1) for a turbocharger includes a hub (6) extending axially between a nose (10) and a partial back wall (9) defining an axis of rotation in the axial direction. The partial back wall (9) extends circumferentially from the hub (6) to an outer peripheral edge (11). A plurality of turbine blades (7) are coupled to the hub (6) and extended beyond the peripheral edge (11). The blades (7) are spaced circumferentially about the hub (6) at equal intervals around the axis of rotation. At least one scallop cut (5) is formed in the peripheral edge (11) at the partial back wall (9) for balancing the turbine wheel (1) about the axis rotation.

Abstract: The invention relates to an actuator device for torque transmission equipment such as a clutch, e.g. a friction clutch or dog clutch, or a brake, comprising at least two electric motors, wherein the rotors of the electric motors are kinematically coupled together via a summation gear, and the summation gear has an output side which is coupled to an actuator of the torque transmission equipment in such a way that a state of the actuator can be set as a function of a relative rotation between the two rotors.

Abstract: A bottom bracket assembly of a bicycle that cooperates in an eccentric or off-center manner with a bottom bracket shell of a bicycle frame. The eccentric bottom bracket assembly has a cylindrical insert with an off-centered opening for receiving a spindle that connects to cranks of the crankset. Rotating the cylindrical insert repositions the off-centered opening relative to at least the longitudinal direction of the bicycle and thus can be used to adjust the tension in the flexible drive member of the bicycle. A worm gear arrangement provides controlled manipulation of the position of the insert relative to the bicycle frame.

Abstract: A rotary device associated with drive means. The rotary device comprises a shaft and/or a hub and balancing means for balancing its rotational motion. The balancing means has a hollow chamber surrounding the hub and a solid/fluidic material with thixotropic properties, which fills partly the hollow chamber.

Abstract: An adjusting mechanism for desired angle of an oscillating electric fan is disclosed. The adjusting knob is conveniently located about the top rear portion of the fan motor, adjacent the clutch knob. Adjusting the oscillating angle may be made when the fan is at rest, when it is running and oscillating at the same time, or when it is running at a fixed direction. Adjusting is fast and simple, only one hand is needed and no tools and mechanical know-how is necessary.

Abstract: An apparatus is disclosed for aiding in the speed and simplicity of the adjustment of the clicker-style cam bolts employed by TRA-type snowmobile drive clutches, manufactured by Bombardier Recreational Products. The apparatus comprises a barrel type nut with a collared head and a compression wire spring which fits telescopically over said nut and against said collared head, and a locking set screw to secure the apparatus against rotational movement or removal. This assembly replaces the conventional hexagonal lock nut presently used on TRA-type drive clutches. This apparatus enables the user to change the linear position of the cam bolt in the drive clutch housing to enable the hexagonal head of the clicker-style bolt to clear its respective hexagonally indexed pocket, which is molded into the drive clutch housing, and to be turned to any one of six different degrees of rotation, thereby changing the shift-out RPM setting of the drive clutch quickly and with greater ease than conventional methods.

Abstract: The present invention discloses a clutch mechanism to adjust eccentricity in a power tool. The clutch mechanism comprises an outer race mounted radially on an annular main body which is mounted on an eccentric shaft. At least one first connecting member is disposed between the outer race and the annular main body. At least one second connecting member is disposed between the annular main body and the eccentric shaft. The first connecting member makes the outer race and the annular main body rotate relative to each other at one way. The second connecting member makes the annular main body and the eccentric shaft rotate relative to each other at one way. The annular main body has an axial projection formed thereon to connect with an eccentric mechanism in the power tool. With this type of clutch mechanism, the adjusted eccentricity will not change during working and torque can be transferred stably.

Abstract: The invention relates to a method for adjusting a wiping angle (?1, ?2) between a park position and a reversal position (28, 30) of a wiper lever (16, 18) of a windshield wiper system for a motor vehicle with at least one wiper lever (18) whose park position or reversal position (30) runs approximately parallel to an A pillar (14) of a vehicle body, which laterally delimits a windshield (10), wherein the wiping angle (?2) is adjusted by means of an eccentric ball pivot (60), which is arranged on a free end of a driving crank (54) and connects the same to a motor crank (52) in an articulated manner by means of an articulated rod (42), while the other end of the driving crank (54) sits on a drive shaft (56) in a rotationally fixed manner, said drive shaft driving a fastening part (58) of the wiper lever (18).

Abstract: A vehicle wheel includes a wheel body having an elongated guiding slot radially extended from a center of the wheel body; and an axle centrifugal adjusting arrangement, which includes a sliding member slidably mounted along the guiding slot for mounting the wheel body to the wheel axle; and a gear adjustment device including a first gear unit mounted at the guiding slot of the wheel body, and a second gear unit mounted at the sliding member to substantially engage with the first gear unit so as to selectively adjust the sliding member to slide along the guiding slot.

Abstract: An automatic balancing device for a rotatable system includes a track (18) arranged about a rotational axis (H) of the rotatable system and having two surfaces (22a, 22b) inclined toward each other in a direction of a centrifugal force acting (F) acting on at least one balancing body (20) which is received in a cross-section formed by the two inclined surfaces (22a, 22b) and limited by an elastic locking element (24) arranged therebetween for displacing the at least one balancing body (20) away from the inclined surfaces (22a, 22b) in a direction opposite the direction of the centrifugal force (F) and for pressing the at least one balancing body (20) against an inner boundary of the track (18) for locking the balancing body (20) when a rotational speed of the system is below a predetermined threshold.
