Definitions

  • the stay according to claim 2 of the present invention includes a stay main body and a notch plate integrally formed with a retainer integrally rotatable with an inner peripheral side of the stay main body.
  • a lubricating recess is provided on a sliding surface of the notch plate which slides with the stay main body.
  • the lubricating concave portion is provided on the sliding surface of the stay main body that slides with the notch plate.
  • the present invention having the above-described contents is characterized in that the notch width of the notch plate engaging with the strut is shorter than the length of the strut in the notch plate which is an assembly part of the notch type stay. It is also a feature.
  • annular resin or aluminum stay body 2 is provided, and the stay body 2 is provided with an inner wall 3, a blade 4 and an outer ring 5 in the body.
  • a ring-shaped pocket plate 6 is also integrally formed on the inner peripheral side of the ring 3.
  • a notch plate 7 having an annular shape is provided on the inner peripheral side of the stay main body 2 so as to be relatively rotatable, and a retainer (also referred to as a bearing support) 8 having an annular shape is formed on the notch plate 7.
  • a snap ring 9 is fitted around the inner periphery of the stay body 2 to prevent the notch plate ⁇ integrally formed with the retainer 8 from coming off in the axial direction.
  • a spline is provided on the inner peripheral surface of the notch plate 7 to be fitted to the stay shaft.
  • a groove-shaped concave portion is formed on the end face 10 a and the inner peripheral face 1 Ob of the step portion 10 in the stay body 2.
  • (Also referred to as ATF lubrication grooves) 17 are provided in a required number evenly distributed (eight equally distributed in the figure).
  • notch plate 7 and the retainer 8 which are separate parts in the past, are integrated with the stay 1 having the above configuration, the number of parts is reduced and the manufacturing cost is reduced.
  • the axial dimension has been reduced.
  • a groove-shaped recess is formed on the end face 10a of the step portion 10 and the inner peripheral surface 1Ob of the stay main body 2 which slides on the notch plate 7 on which the retainer 8 is integrally formed. Since the required number of 17 is provided in an evenly distributed manner, the sliding surface is lubricated with the lubricating oil stored in or flowing through the concave portion 17, resulting in sliding wear on the sliding surface. Can be suppressed. Therefore, the durability of the sliding portion can be improved while reducing the manufacturing cost.
  • a swing angle limiting portion (also referred to as a swing stopper) 21 for limiting the swing of the strut 15 to a predetermined angle is formed inside the pocket portion 13.
  • a side of the swing angle restricting portion 21 in order to restrict the movement of the strut 15 in the direction of the mating surface 13 b in the pocket portion 13.
  • a portion 23 is open, and a bottomed hole-shaped spring mounting portion 23 provided in the axial direction of the stay 1 (vertical direction in FIG. 12) is provided with a spring 1 made of a coil panel. 4 is also attached to extend and contract in the axial direction of the stay 1.
  • the present invention can be widely applied not only to resin-made stays but also to aluminum-made stays.

Abstract

L'invention porte sur un stator comprenant un corps principal et une plaque à encoche assemblée sur le côté périphérique interne du corps et qui tournent l'un par rapport à l'autre, la plaque étant intégrée à un dispositif de retenue. Une partie évidée lubrifiante est ménagée dans la surface frottante du corps principal du stator frottant contre la plaque à encoche. On supprime l'apparition de l'usure due au frottement contre la plaque à encoche intégrée dans le dispositif de façon à satisfaire aux exigences de réduction des coûts de production et d'assurance de durabilité de la plaque à encoche.
