  • Patent number: 7108104
    Abstract: A lubricant applicator for disposing lubricant onto a metal surface. The lubricant applicator generally includes a combination holder and dispenser. Lubricant is disposed from the same portion of the combination holder and dispenser as the lubricant was inserted, in the rear portion of the combination holder and dispenser. A dispensing system applies constant force to the rear portion of the combination holder and dispenser so that lubricant is disposed from the rear portion and out of the front portion of the combination holder and dispenser. Lubricant, generally in the form of a stick, can therefore be easily replaced without removing the applicator from its location or without removing its mounting arrangement. Various applications and mounting arrangements for the lubricant applicator are disclosed, as is a method for providing a lubricant applicator.

  • Patent number: 7077023
    Abstract: In a toroidal continuously variable transmission, a roller-and-cage bearing assembly is interleaved between a power-roller outer ring and a trunnion power-roller accommodating portion to permit a parallel translation of a power roller in an axial direction of input and output disks. A cage of the roller-and-cage bearing assembly is formed with an oval slotted hole. A disk-shaped member is attached to the trunnion power-roller accommodating portion. The slotted hole and the disk-shaped member are fitted to each other to define a predetermined clearance that limits a displacement of the roller-and-cage bearing assembly in a direction perpendicular to both a rotation axis of the power roller and a trunnion axis to a set displacement.
