Definitions

  • the invention relates to an elevator winch, in which the output shaft on which the cable pulley intended to support the load is mounted is carried by two bearings arranged in a winch housing and by a third bearing provided outside the winch housing at the end of the cable pulley.
  • Such winches comprising three bearings for the output shaft are commonly used when the importance of the load supported by the cable pulley is such that an arrangement of the latter in overhang would imply an exaggerated increase in dimensions, both the output shaft and the bearings or other components of the winch associated with it. This is the case, for example, in elevators for people with high transport capacity or for certain freight elevators.
  • the installation, at the end of the output shaft, of this additional bearing separately attached to the base plate supporting the winch housing or to a base plate attached thereto adjacent requires significant alignment work. With such a hyperstatic system, if the alignment of the bearings is not perfect, there is the risk of abnormal wear of one of the bearings and / or the output shaft, or the risk of a break in the latter by fatigue due to the fixing constraints of the third bearing.
  • the German application n ⁇ ST 1445 shows an elevator winch in which, to avoid the use of a third bearing, the winch housing is equipped with a fixed cylindrical sleeve which exceeds the housing and inside which the he winch output shaft is housed rotating.
  • the cable pulley is arranged to rotate on the end of the cylindrical sleeve, and its hub has a keyed drive nose on the end of the output shaft projecting from the sleeve.
  • the object of the present invention is to provide an elevator winch which, without departing from the field of simple constructions, makes it possible both to facilitate the assembly operations of the winch and to avoid the risks of breaking the output shaft. .
  • the major advantage of the invention lies in particular in the fact that a prestressing of the output shaft in a radial direction opposite to that of the force exerted by the load is made possible, so that when the cable pulley is subjected to the load, relief of the bearings of the winch housing as well as an appreciable reduction of the working rate of the output shaft and, consequently, of its weariness can be obtained.
  • the invention not only makes it possible to avoid breaking the shaft, but it also makes it possible, to a certain extent, to reduce the dimensions of the latter and of the elements, such as the bearings, which are directly to it. associated. It follows that, for an elevator with a given load, a lighter, therefore less expensive winch construction can be envisaged, just as, within the permitted limits, the admissible load can be increased for a given winch model.
  • the reference 1 designates a base plate, or winch frame, which is intended to be placed in the room of the elevator machinery and on which is fixed a winch box 2 containing all or part of the elevator drive mechanism, not shown, such as a worm gearbox, the braking system or any other conventional elements associated with the drive motor not shown.
  • the reference 3 designates the output shaft which is carried by two bearings, not shown, arranged inside the winch housing 2 and on which is mounted the cable pulley 4, or grip pulley, to which are respectively suspended, by cables 5 and 6, from the elevator car and counterweight, also not shown.
  • Reference 7 designates an auxiliary bearing, or third bearing, disposed outside the winch housing, at the end 3.1 of the output shaft 3.
  • the end of this third bearing 7 has a straight face 7.1, against which one of the ends of a pressure spring 8 is applied, the other end of which takes support on the bottom of a guide cup 9 mounted at the end of the screw 10 of a screw tension adjustment device 10 and nuts carried by a curved part 12.1 of a support plate 12 capable of being oriented by rota-. tion around the output shaft 3.
  • the reference 13 designates an amount which is provided integral with the base plate 1 and to which, once oriented in the desired position, the support plate 12 can be fixed by means of three bolts fixing 14.
  • the angle of rotation allowed for the support plate 12 relative to the upright 13 is sufficient so that, during assembly and depending on the result of the cables 5 and 6, the elastic force R by which, under the action of the spring 8, the third bearing 7 and, consequently, the output shaft 3 are biased radially, is exerted in the direction opposite to that of the force G exerted on the output shaft 3 by the cable pulley 4 supporting load.
  • the dimensions and characteristics of the pressure spring 8 are chosen as a function of the force G, so that a prestressing of the output shaft 3 can be generated from a simple adjustment of the tension of the spring 8 by means of screw 10, preload which will be compensated once the load supported by the cable pulley 4.
  • the risks of rupture by fatigue of the output shaft 3 can be practically eliminated, and a work of alignment of bearings is no longer necessary during assembly .
