Definitions

  • FIG. 4 shows a longitudinal section through the gear of FIG. 1 along the worm shaft
  • the opening 9 of the gear housing 1 is preferably provided in order to insert and mount the bearing 14 remote from the drive and the pretensioning device 15 in the housing 1.
  • the cover base 80 has a base surface which is curved outwards in the region of the screw shaft 3.
  • the first dome resulting from this bulge 16 is essentially cylindrical, with a circular base.
  • the first dome 16 provides a stop for the worm shaft 3 on its outer side facing the worm shaft 3.
  • the end of the worm shaft 3 on the cover side is spaced in the longitudinal direction from the outside of the first dome 16 of the cover 8.
  • the longitudinal axis of the dome and the worm shaft preferably coincide.
  • the diameter of the first dome 16 is chosen such that in this exemplary embodiment it is at least as large as the outer diameter of the inner ring 120 of the bearing 12 remote from the drive.
  • the first dome 16 also serves as an axial stop for the bearing 12 remote from the drive
  • the bearing seat of the non-drive bearing may settle, causing the bearing to move and the transmission to be damaged.
  • the worm shaft therefore requires an axial lock that is greater than or equal to 2 kN, which prevents the gear from being damaged.
  • the cover 8 with the first dome 16 provides such axial securing for the worm shaft and the non-drive bearing ready. No further components are provided between the screw shaft 3 and the cover 8 in the axial direction, so that the screw shaft 3 strikes directly on the outside of the cover 8 or the cover base 80 without additional suspension.
  • the serrated edge 83 of the cover is designed such that it extends in the opposite direction to
  • Jagged edges can assume a different length, width and / or height.
  • a spike can have a second spike height h2, deviating from the first spike height h1.
  • the point height is h2 ⁇ hl, but hl> h2 can be formed.
  • FIG. 10 shows schematically that at least one prong has a width of the first prong width d may have a different second prong width d2.
  • d2> d but d2 ⁇ d can be formed.
  • the same can be implemented for at least one spike length x.
  • the second prong length x2 is less than x, but x> x2 can be formed.
  • the cover preferably has a smaller one in all embodiments

Abstract

L'invention concerne un engrenage à roue et vis (2) destiné à une direction assistée électromécanique comprenant un arbre (3) en prise avec une roue à vis (6), l'arbre (3) étant agencé dans un carter (1) d'engrenage et étant monté dans le carter (1) d'engrenage de manière à tourner autour d'un axe longitudinal (4), dans un système de palier (11) côté entraînement à sa première extrémité et dans un système de palier (12) côté opposé à l'entraînement à sa seconde extrémité. Le carter (1) d'engrenage présente dans le prolongement de l'arbre (3), à une extrémité opposée à l'entraînement, une ouverture (9) qui peut être fermée par un couvercle (8), le couvercle (8) présentant un fond (80) de couvercle et un bord périphérique (81) de couvercle, et le fond (80) de couvercle présentant dans la zone de l'arbre (3) une partie bombée (16) qui forme une sécurité axiale de l'arbre (3).
