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 snaps into place at the end of the tree , of this additional landing fixed to the base plate supporting the winch or a base plate adjacent to it, however, requires significant alignment work.
  • 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 rupture of the latter by fatigue due to the fixing stresses of the third bearing.
  • German application No. 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 protrudes beyond the housing and inside which the winch output shaft is log. ant.
  • the cable pulley is arranged round 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.
  • An elevator winch in which the output shaft is also carried by two bearings arranged in a winch housing and for which a third bearing is provided for the output shaft outside the winch housing, is also shown.
  • German application DE-B- 1 269 317 to compensate for misalignments or inaccuracies that may exist between the part of the base plate which supports the winch housing and that supporting the third bearing, the housing winch is connected articulated at one point to the base plate by means of pendulum supports.
  • pendulum supports are made up of rigid connecting elements, the ends of which are articulated respectively to the housing, or spacers capable of slight bending, formed by the core of l-shaped profiled parts on which the winch housing.
  • This construction avoids J n alignment work of the third bearing which can in this way be rigidly fixed to the base plate.
  • the housing of the output shaft in the third bearing as well as in the winch housing are provided with a ball joint, this in order to compensate for the slight inclinations of the output shaft which may result from the pivoting of the winch, around the articulation point constituted by the pendulum supports.
  • the non-rigid attachment of the winch housing to the base plate is liable to generate vibrations.
  • 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 breakage of the output shaft while retaining a rigid attachment for the winch housing. This object is achieved with the elevator winch of the invention as characterized in the claims.
  • the major advantage of the invention resides in particular in the fact that a prestressing of the see 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 in the working rate of the output shaft and, consequently, of its fatigue 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.
  • 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.
  • the 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 lower part of this third bearing 7 has a rectilinear face 7.1, against which s applies one end of a pressure spring 8, the other end of which rests on the bottom of a guide cup 9 mounted at the end of the screw 10 of a tension adjustment device at screws 10 and nuts 11 carried by a curved part 12.1 of a support plate 12 capable of being oriented by rotation 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 fixing bolts 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 cables 5 and 6, the elastic force ique R by which, under the action of 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 shaft outlet 3 by the cable pulley 4 supporting the 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 the screw 10, prestressed 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 n ' is no longer necessary during assembly.
