  • Patent number: 5180295
    Abstract: A scroll compressor 10 includes a housing 12, a fixed scroll 26, an orbital scroll 48, a scroll drive assembly 74 and an axial thrust and anti-rotation assembly 108. The axial thrust and anti-rotation assembly includes a pair of scroll key ways 110 and 112, a pair of housing key ways 122 and 124 and an Oldham coupler 132 with key blocks 140 and 142 positioned in the scroll key ways and a pair of key blocks 148 and 150 positioned in the housing key ways. Axial loads exerted on the orbital scroll and end plate 50 by fluid under pressure are transferred from the end plate 50 to roller bearings 118 and 120 mounted in the scroll key ways 110 and 112, to the key blocks 140 and 142, to the ring 134 to thrust roller assemblies 156 and 158 in contact with a surface 136 of the Oldham coupler ring 134 and to the housing 12.

  • Patent number: 5112197
    Abstract: An assembly for providing socket plate torque restraint for a variable displacement wobble plate refrigerant compressor includes a non-rotary cross groove joint. The joint has a cylindrical outer race, a cylindrical inner race, slightly angled helical grooves in the races, a plurality of torque receiving balls and a cage for properly maintaining and positioning the balls in the cooperating grooves for operation. The joint is connected to a fixed anti-rotational shaft. The shaft is in the form of a sleeve and forms the inner race to effect torque restraint, but at the same time allow for translational axial motion of the socket plate. Radial and thrust bearings mount said socket plate relative to the rotary hub/journal. Lubricating fluid carried by the gaseous refrigerant lubricates the grooves and is then transferred by a passage extending from the grooves in the outer race to the radial/thrust bearings.

  • Patent number: 4494946
    Abstract: A flexible continuous device is provided for transmitting torque between a driving pulley and a driven pulley. The device comprises a plurality of strut members arranged in aligned side-by-side relation with each member having a predetermined pitch radius relative to the pulley axes. Adjustably engaging a corresponding surface of each strut member is a continuous flexible band member. The engagement between the band member and each strut member surface is at a greater radius than the pitch radius when the strut member is in contact with the periphery of a pulley. A unit is mounted on each strut member and coacts therewith to retain the band member and strut members in assembled relation. Each unit has a portion thereof which protrudes longitudinally of and overlies the exterior of the band member. The protruding portion of each unit extends a predetermined distance beyond the strut member on which it is mounted. The protruding portions of adjacent units are disposed in substantially nested relation.
