Definitions

  • the invention relates to a method for mounting hollow objects with a conical opening on a conical shaft.
  • a bearing can be mounted on a conical seat.
  • a method for mounting a hollow object with a conical opening is known.
  • the object is first pushed onto the shaft in such a way that the conical surfaces of the object and the shaft are in a neutral position. Position against each other.
  • a predetermined axial force is exerted on the object, which moves it from the zero position to a starting position and provides for an initial interference or interference fit.
  • the predetermined axial force is defined as the force required to produce in the initial position an elastic extension of the hollow object of 5 to 20% of the elastic insertion in the end position.
  • the article is axially displaced from the home position over a predetermined distance to an end position to achieve a final press or interference fit.
  • the object of the present invention is therefore to provide a method for mounting a conical-bore hollow object on a conical shaft, which allows a simpler and more accurate mounting of the object independently of the present shaft geometry and the elastic extension in the end position allows.
  • the assembly of a hollow object with a conical opening on a conical shaft is carried out according to the invention according to the following steps: First, the article is pushed onto the shaft so far that its conical surfaces abut one another with those of the shaft in an initial position.
  • a starting force is exerted on the object in the axial direction, for the axial displacement of the hollow object from the starting position to a starting position.
  • the value of the starting force is set in such a way that, when displaced to the starting position, a widening of the hollow object as a result of the starting force results from 22 to 45% of a predefined total widening of the hollow article in the fully assembled state.
  • the hollow object is widened defined in the radial direction.
  • the object on the shaft is moved from the start position via a displacement path to an end position to create the predetermined total expansion.
  • An essential advantage of the method according to the invention is that in the invention the displacement between start and end position or the starting position itself is optimized, i. due to a comparison with the known method according to the invention increased starting force of the displacement between the start and end position is reduced by the invention.
  • the hollow object is an inner ring of a roller bearing.
  • the inner ring shifts due to the total expansion to the end position, so that there is a smaller internal clearance between the rolling elements and inner ring at the mounting end.
  • a hydraulic nut is used for mounting the hollow object.
  • the hydraulic nut engages in a screw threaded portion of the conical shaft.
  • the use of a hydraulic nut ensures that the pressure required for mounting is available. For applications that require lower pressure, for example, shaft nuts and pressure screws can be used.
  • the predetermined overall expansion can be determined as a function of a shaft geometry, for example conical conditions, shaft cross-sections, hollow or solid shafts, a shaft surface, material properties and / or external stresses of the bearing during operation, e.g. high loads, shock loads, shaft bends, oscillating stresses, and / or temperature effects are set.
  • FIG. 1 shows a sectional view of an arrangement for carrying out a method according to the invention
  • Fig. 2 is a schematic representation of the movement during the inventive method.
  • FIG. 1 shows a view of an arrangement for carrying out a method according to the invention in longitudinal section. Although such an arrangement is known in principle from the prior art, it should be included to explain the method according to the invention.
  • FIGS. 1 and 2 will be used.
  • the roller bearing 01 When mounting the roller bearing 01, the roller bearing 01 is pushed onto a conically shaped portion 06 of the shaft 05, to such an extent that the conical surfaces of the inner ring 02 and the shaft 05 abut each other.
  • This position is designated by A (starting position) in FIG.
  • the inner ring 02 is moved from the starting position A to a starting position S. This is done by pumping oil into a chamber 10 of the hydraulic nut 08. It is on the inner ring 02 by a slidingly disposed in the chamber 10 annular piston 11th exerted a starting force in the axial direction, which causes an expansion of the inner ring 02 via the wedging action between the hollow object and the shaft.
  • the amount of this starting force is dependent on the end position to be taken and the thereby to be achieved, predetermined total expansion of the inner ring 02.
  • the elongation of the inner ring O 2 caused by the starting force amounts to at least 22% of the total widening and can be varied up to a maximum of 45% of the total widening.
  • the predetermined total expansion in this particular case is 0.45% o of the inner ring bore diameter.
  • the total expansion depending on the shaft geometry, the shaft surface, the material and / or the external stress of the bearing in operation and / or the temperature can be set.
  • the inner ring 02 is moved up the shaft 05 via a displacement path s v to the end position E, thereby achieving a tight fit of the inner ring 02.
  • the displacement path s v is independent of the desired overall widening of the inner ring 02 and, according to the method, always has the same predetermined amount.
  • the starting position required for each is achieved by the variable starting force.

Abstract

L'invention concerne un procédé pour monter sur une tige conique des objets creux dotés d'une ouverture conique, comprenant les étapes suivantes : - l'objet est enfoncé suffisamment profondément sur la tige pour que ses surfaces coniques se trouvent en application avec celles de la tige dans une position de base ; - une force initiale est exercée sur l'objet en direction axiale afin de déplacer axialement l'objet creux de la position de base vers une position initiale, la valeur de la force initiale étant réglée de telle sorte qu'on obtient, lors du déplacement dans la position initiale, un élargissement de l'objet creux du fait de la force initiale atteignant 22 à 45 % d'un élargissement total prédéfini de l'objet creux dans l'état monté définitif ; - l'objet est déplacé sur la tige sur une course de translation allant de la position initiale à une position finale, afin de produire l'élargissement total prédéfini.
