In a component for connecting a shaft to a clamping holder that can receive a rotor, the clamping holder is able to be inserted into a cup-shaped housing and is able to be fixed there by fasteners. On the housing base of the housing is a connector for connecting the housing to the shaft in a torque-proof manner. The fasteners are arranged with their base surface on the outer lateral surface of the housing, and can be brought into engagement with the clamping holder by bores present in the housing. The fasteners have at least one recess in the base surface, such that they rest with their base surface on the outer lateral surface only in some regions.

A fan inspection jig includes a jig assembly having multiple spring abutment pillars for holding two sides of a fan (or a series fan) to make the fan or the series fan positioned in a suspending position. A vibration sensor is disposed in at least one of the spring abutment pillars of two sides of the fan for measuring a vibration signal of the fan in operation.

An apparatus for applying weight material onto a wheel may include a conveyor assembly, upper and lower severing-head assemblies, and upper and lower control arms. The severing-head assemblies may be mounted above and below the conveyor assembly and may include a housing, a severing device and a dispensing mechanism. The dispensing mechanism may position the weight material from a source relative to the severing device. The severing device may separate a predetermined amount of weight material from a source. The control arms may be movably mounted above and below the conveyor assembly and have weight-application tools configured to transfer the predetermined amounts of weight material from the severing-head assemblies to locations on the wheel.

A vibration isolation holding device includes a body portion and an abutment member. The abutment member is arranged between the body portion and a bearing housing, and has an abutment surface abutting on the bearing housing, when a cartridge is held. A biasing member is disposed between the abutment member and the body portion. An interval between the body portion and the abutment member is regulated by a first regulating portion to be shorter than a natural length of the biasing member.

An assembly of a rotating component and a rotationally stationary component includes a first bearing portion located at the rotating component and rotatable therewith, and a second bearing portion located at the rotationally stationary component. The second bearing portion is supported at the rotationally stationary component and rotatably with the rotating component when in contact with the first bearing portion. The first bearing portion and the second bearing portion define a single point contact therebetween.

A clamping device for clamping an article or workpiece to be balanced includes a clamping apparatus for clamping the article. The clamping apparatus has an adjusting device for adjusting the clamping diameter of a clamping body of the clamping apparatus for clamping the article on a placement surface. The clamping body has a disk-shaped spring element sprung in radial direction with a centrally disposed clearance forming at least one spring element cone. The clamping body also has a clamping element inserted into the clearance and having at least one corresponding clamping element cone. The adjusting device has an actuating device for displacing the clamping element relative to the spring element, for moving the cone surfaces of the clamping element cone and the spring element cone relative to one another and for consequently clamping and/or unclamping the spring element in radial direction by the cone surfaces.
