Definitions

  • the invention relates to a pulley for use in control and aggregatriementrieben of internal combustion engines with an attachment to the engine block by means of stud bolts and nut, and with a spacer between see Stud and inner bearing bore.
  • the invention is therefore the object of a deflection roller of the type mentioned in such a way that with a simple structure, a simplified assembly is possible.
  • the invention provides that the spacer of two attached on both sides of the ball bearing ring, with protruding annular collars on the end faces and applied in Achsrich- tion of the role of game with each other opposing, releasably supported on the ball bearing inner ring parts consists ring parts.
  • the ring parts are inserted in circumferential grooves elastic rings with excess so that they survive in the resting state slightly beyond the outer peripheral surfaces of the ring parts, are pressed into the ball bearing inner ring.
  • the ring parts are provided with mutually overlapping offset front ends, of which at least one with an open to the mating ring part, a elastic ring is provided with oversize receiving circumferential groove.
  • an elastic ring for example, a round cord rubber ring.
  • the ring parts are made of ferromagnetic material, and that in the end face of an annular part, a preferably circumferential permanent magnet is embedded.
  • 1 shows a section through a deflection roller according to the invention with stud fastening on the engine
  • 2 shows a partial section through a modified Umlenkrollenbefest Trent, in which each ring member of the spacer is mounted separately on the ball bearing inner ring via an elastic rubber ring,
  • FIG. 3 a of FIG. 2 corresponding section through an embodiment with magnetic support of the ring parts of the spacer to each other and

  • This spacer compensates on the one hand for the tolerances between the inner bore of the ball bearing inner ring 8 and the outer periphery of the stud bolt 2 and on the other it acts through the length training of the ring member 5a as a spacer to the engine.
  • the design is such that the two-part spacer 5 is connected to the guide roller 2 prior to attachment to the stud bolt 2, specifically by a detachable mounting on the ball bearing inner ring 8.
  • the offset front end 11a of the ring member 5a is provided with a circumferential groove 12, in which an elastic ring 13, such as a round cord rubber, is inserted with slight oversize, so when superimposing the front ends 11 a and 11 b of the elastic ring 13 is compressed radially must be and thus a clamping bracket of the ring parts 5a and 5b is given to each other.
  • the two ring parts 5a 'and 5b' are each held separately by means of elastic rings 13 'inserted in grooves 12' directly on the inner surface of the ball bearing inner ring 8.
  • a permanent magnet 15 is inserted, so that when attaching the ring parts from the left and right to the ball bearing of the guide roller 4, the two ring parts are held together by the magnetic attraction.

Abstract

L'invention concerne une poulie de renvoi utilisable dans des transmissions par courroie de commande ou d'unité dans des moteurs à combustion interne et dont la fixation sur le bloc moteur se fait au moyen de boulon d'ancrage et d'écrou, une pièce d'écartement étant placée entre le boulon d'ancrage et un alésage de palier intérieur. Cette pièce d'écartement (5) est constituée de deux éléments annulaires (5a, 5b) montés de part et d'autre de la bague de roulement à billes (8), s'appuyant contre les surfaces frontales (18, 19) de cette bague au moyen de collets annulaires en saillie (6, 7), se faisant face avec du jeu dans le sens d'axe de la poulie (4) et fixés de manière détachable sur la bague intérieure de roulement à billes (8).
