Abstract: A pulley for a CVT has a fixed sheave, a movable sheave, a spider, a biasing member biasing the movable sheave axially away from the fixed sheave, at least one centrifugal actuator and at least one roller assembly. The at least one centrifugal actuator has an arm pivotally connected to one of the movable sheave and the spider. The arm has a thrust portion pushing against a track portion of a roller of the at least one roller assembly upon rotation of the CVT, the roller being rotationally connected to another one of the movable sheave and the spider. The roller receives the thrust portion of the arm on the track portion thereof such that the thrust portion of the arm remains in contact with the track portion of the roller. The arm and the roller thereby transfer axial and rotational forces between the spider and the movable sheave.

Abstract: An electric motor, transformer or inductor having a cooling system. A stack of laminations have apertures at least partially coincident with apertures of adjacent laminations. The apertures define straight or angled cooling-fluid passageways through the lamination stack.

Manifold members adjoin opposite ends of the lamination stack, and each is configured with one or more cavities to act as a manifold to adjacent passageway ends. Complex manifold arrangements can create bidirectional flow in a variety of patterns.

Abstract: A crankshaft damper and a method of crankshaft damper assembly using interlocking beads. A crankshaft damper having a hub portion and pulley ring and an elastomeric member disposed in an annular space between them is clamped in a tool after initial assembly. A tool having jaw teeth on oppositely disposed, cooperating jaws engages the crankshaft damper hub portion and pulley ring on either side of the elastomeric member. The tool jaws press on the hub portion and pulley ring to create beads or crimps on the hub portion and the pulley ring. The beads or crimps are formed in cooperating groups or sets. They press the elastomeric member into the form of a curve or wave. The curve or wave mechanically locks the hub portion and pulley ring together, thereby locking the elastomeric member in place between them.

Abstract: The axial displacement of the clutch retainer 28 of the roller clutch 10 is prevented. And, part of the clutch retainer 28 is prevented from rubbing the portion which rotates together with the follower pulley 7 to suppress the heat generation during overrun. Accordingly, grease degradation is prevented and durability and reliability are improved. During assembling, with the inner clutch-race 21 being inserted midway on the radially inner side of the rollers 26, the clutch retainer 28 is rotated relative to the inner clutch race 21. With this operation, the inner-clutch race 21 is completely inserted while the springs are simultaneously compressed to press the rollers 26. Accordingly, the circumferential location of the rollers 26 is properly maintained while the inner clutch-race 21 is easily installed on the inner diameter side of the rollers 26 and so the assembling process thereof become easy.
