A cutting assembly includes a knife assembly having a knife holder and a knife blade, a counter knife, and a scoring tip holder. In one arrangement, the counter knife is secured to a ring strander drum, the knife holder and scoring tip holder are carried by a clamping element, and knife blade is disposed between the counter knife and the knife holder. In a closed position, the clamping element causes the knife and scoring tip holders to generate a compressive force against the counter knife, thereby securing the knife blade within the cutting assembly. In an open position, the clamping element positions the knife and scoring tip holders in a spaced relationship relative to the counter knife, thereby allowing removal of the knife blade from the cutting assembly. Accordingly, an operator can replace the knife blade in the cutting assembly without having to remove the entire cutting assembly from the ring strander device.

A knife assembly includes a knife blade and a mounting assembly having a knife blade support portion extending along a longitudinal axis of the mounting assembly. The knife blade support portion is constructed and arranged to position a cutting edge of the knife blade distal to a leading edge of the mounting assembly. The mounting assembly also has a counter knife portion disposed at the leading edge of the mounting assembly that defines a set back distance with the knife blade. The set back distance is constructed and arranged to provide a travel path for a wafer.

To solve both axial and rotational constraint problems in turbochargers with rolling element bearings (REBs), a REB sleeve or outer race is mounted to the bearing housing in a way that is not axially and radially rigid, thus allowing for oil damping films both radially and axially. At the same time, the REB sleeve or outer race is held so that the REB sleeve or outer race does not rotate relative to the bearing housing. This dual purpose is achieved using an anti-rotation ring and a damping ring. The anti-rotation ring includes at least one anti-rotation feature for engaging the bearing housing and at least one anti-rotation feature for engaging the REB cartridge, preventing rotation of the REB cartridge sleeve or outer race. The damping ring axially locates the REB cartridge and dampens axial movement and cushions axial thrust.

The propensity for gas leakage around a shaft, which extends through a bore which connects volumes of differing pressures, e.g., a turbocharger turbine housing and the ambient air, is minimized with the addition of a pair of seal rings biased by a gas pressure to provide a continuous gas and soot seal.

The spring may bias the seal rings apart from each other or towards each other.
