Definitions

  • the invention relates to a bearing device for the winch of the elevator car of a passenger or goods lift, with a gear housing in which a driven worm and a worm wheel connected via a shaft to a worm gear arranged outside the gear housing and meshing with the worm are arranged, the bearing device has a pivot bearing for the gear housing and a fixed bearing formed by a support bracket.
  • the car of a passenger or goods lift is operated by a winch, which is usually arranged at the upper end of the elevator shaft and consists essentially of a reduction gear with worm and worm wheel.
  • the worm and worm wheel are stored in a gear housing filled with oil.
  • the slow-running worm wheel shaft of the transmission is connected to a rope pulley or traction sheave over which the cables carrying the car run, while the fast-running worm shaft is almost always in a drive connection with an electric motor designed as a three-phase motor.
  • the winch is also equipped with a braking device, which usually has two brake shoes provided with brake pad materials, which are held in the open position by means of electromagnets against spring forces, so that the brake automatically responds in the event of a power failure and stops the elevator.
  • a bearing device of the type mentioned is already known, in which a rotary shaft is mounted in both side walls of the gear housing and in a fixed bracket.
  • This design of the known bearing device causes the entire gear housing to constantly carry out slight pivoting movements around the pivot bearing or the pivot bearing on which it rests, in order to always align the two side bearings in its side walls with the rotating shaft in order to prevent them from this type of bearing can cause additional torsional moments in the shaft.
  • the assembly consisting of gearbox, gearbox housing and rotating shaft has only a low level of rigidity and stability.
  • the invention has for its object to provide a storage device of the generic type, which enables a quick and easy and rigid, but stress-free assembly of the bearing housing, such that no additional moments and forces are introduced into the transmission parts during operation and thus their increased Wear is avoided.
  • the gear housing of the winch reduction gear is supported on one side by means of a pivot connection and anchored on the disc side, so that the entire winch device has a degree of freedom which corresponds to a pivoting movement on the pivot connection.
  • This swivel connection is formed by a semicircular profile which is positively mounted in a groove in the housing base and rests with its flat side on a substructure.
  • the semicircular profile has a through hole for receiving a threaded bolt, with which the gear housing can be screwed onto the substructure.
  • the pivot axis is arranged orthogonally to the hollow shaft of the gearbox, which connects the worm wheel to the traction sheave, the hollow shaft being rotatably mounted on a fixed axle which is fixedly connected to the gearbox housing and which is held by the support bracket with its housing-free end.
  • the substructure can be formed by at least one support bracket which can be screwed to the foundation.
  • the pivot axis is divided and formed by at least two semicircular profiles.
  • the then provided three support brackets can be located at the corners of an isosceles triangle, the pivot axis being the Hypotenuse forms, so that the gear is supported by means of a three-point bearing against the foundation.
  • gear housing If the gear housing is now placed on the semicircular profiles and attached to the opposite support bracket opposite the foundation, it aligns itself tension-free on the semicircular profiles, so that it can then be attached to the foundation with two threaded bolts.
  • the production of the bearing shells for the semicircular profiles is very easy to manufacture using a milling device.
  • the housing can also be equipped with two orthogonally arranged flat mounting surfaces, so that it can be installed in a horizontal position or in a vertical position.
  • the winch 1 has a worm 2 and a worm wheel 3, which are arranged in an oil-filled housing 4.
  • the worm 2 is fastened to the high-speed shaft 5 of the reduction gear, one end 6 of the shaft being supported in the front wall of the housing 4 by means of a bearing 7 and the other end in the rear wall 8 by means of a bearing 9 and a fuse 10 .
  • a rotor 11 of a three-phase motor 12 is attached in a rotationally fixed manner or received in the hub 13 of the brake.
  • the worm wheel 3 has a central hollow shaft 13 which forms the slow-running shaft of the reduction gear 4 and is integrally connected to the worm wheel 3.
  • the hollow shaft 13 ends in a flange 14 which is mounted on a bearing 15 and on which the disc 16 is flanged with cable grooves 17 in which the ropes of the passenger and goods lift run.
  • the hollow shaft 13, which connects the worm wheel 3 to the disk 16 via the flange 14, is rotatably supported on a stationary axis 19 with the aid of the bearing 15 and a slide bearing 18. The left end of the fixed axis 19 in relation to FIG.
  • This housing 2 is supported by means of a bracket 20 on a concrete slab serving as a foundation 21, while the other end is firmly connected to the housing 4 of the reduction gear by means of screw bolts.
  • This housing 4 is supported on the concrete slab 21 or a suitable substructure with the aid of two support brackets 22 which are pivotally connected to the housing.
  • This pivot axis extends over the entire length of the housing 4, so that the housing 4 can be pivoted by means of the housing and the two support brackets 22, which can be screwed to the concrete slab 21. 1 and 2 can also be seen that this axis and the axis 19 are arranged orthogonally to each other.
  • the pivot axis shown in FIG. 3 for the gearbox mounting according to the invention is particularly characterized by the simple design and manufacture of the mounting, which, like the hinge mounting on the support brackets 22 according to FIGS. 1 and 2, the requirements for a tension-free, simple and quick assembly of the Gearbox housing on the substructure met.
  • the arrangement of the gear housing 24 in the horizontal and vertical position is made possible in that the gear housing has two flat mounting surfaces, in which holes for threaded bolts can be provided.
  • the gear housing according to FIG. 3 is mounted on semicircular profiles 27, which are received in a form-fitting manner in fillet grooves 28 of the gear housing.
  • the groove 28 is provided in the mounting surface.
  • the fillet grooves are very easy to manufacture using a milling device.
  • the semicircular profiles are standardized parts and are available from specialist dealers.
  • the flat side of the semicircular profiles 27 rest on the substructure or the foundation 30.
  • the transmission housing 4 can align itself on the semicircular profiles 27, so that simple, stress-free assembly is made possible.
  • the semicircular profiles 27 each have two through holes, which are penetrated with the aid of threaded bolts, so that the gear housing 24 can be screwed to the substructure after alignment.
