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 the driven worm and the worm wheel connected to the traction sheave and meshing with the worm are arranged.
  • the car of a passenger or freight elevator is operated by a winch, which is usually arranged at the upper end of the elevator shaft and essentially consists 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 is usually two brakes provided with brake pad materials has jaws, which are held with the help of electromagnets against spring forces in the open position, so that the brake responds automatically in the event of a power failure and stops the elevator.
  • a braking device which is usually two brakes provided with brake pad materials has jaws, which are held with the help of electromagnets against spring forces in the open position, so that the brake responds automatically in the event of a power failure and stops the elevator.
  • the invention has for its object to provide a storage device for the winch of the car of a passenger or goods lift of the type mentioned, which allows quick and safe assembly at a relatively low cost in a short time, and ensures that the housing is stress-free on the Foundation is installed and consequently increased wear of the gear parts is avoided.
  • the gear housing of the winch reduction gear is supported on one side by means of a swivel connection of some kind and is anchored on the disk side, so that the entire winch device has only one degree of freedom which corresponds to a swivel movement on the swivel connection.
  • This pivot connection can either be formed by a hinge, an axle mounted in at least one bearing shell of the transmission housing engaging in two bearings of two support brackets which are arranged on both sides of the housing and can be screwed to the foundation.
  • the hinge axis is arranged orthogonally to the hollow shaft of the gearbox, which connects the worm wheel to the traction sheave, and the opposite bearing device is formed by a support bracket, which can also be screwed to the foundation.
  • the three support brackets are located at the corners of an isosceles triangle, the hinge axis forming the hypotenuse, so that the gear is supported against the foundation by means of a three-point bearing.
  • the hinge axis is divided and is formed by at least two semicircular profiles which are positively mounted in the groove grooves of the housing base and rest with their flat side on a substructure. If the gearbox is now placed on the semicircular profiles and is 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 have two orthogonally arranged flat mounting surfaces be equipped so that it can be installed in a horizontal position or in a vertical standing 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 rope 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 mounted on a stationary axis 19 with the aid of the bearing 15 and a sliding bearing 18. The left end of the fixed axis 19 in relation to FIG.
  • FIGS. 1 and 2 are supported with the aid of a bracket 20 on a concrete slab serving as the foundation 21, while the other end is firmly connected to the housing 4 of the reduction gear with the aid 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 connected to the housing by an axis 23 which allows a pivoting movement.
  • This axis or pivot extends over the entire length of the housing 4, so that by means of the housing and the two support brackets 22, which can be screwed to the concrete slab 21, and the axis 23, a hinge is formed, around which the housing 4 can be pivoted. It can also be seen from FIGS. 1 and 2 that the two axes 19 and 23 are arranged orthogonally to one another.
  • FIGS. 3 to 5 for a further gearbox mounting according to the invention is particularly characterized by the simple design and manufacture of the mounting, which, like the hinge mounting according to FIGS. 1 and 2, meets the requirements for tension-free, simple and quick mounting of the gearbox housing the substructure.
  • FIG 3 shows a side view of the transmission housing 24 in two positions, namely with solid lines in the horizontal position and with the grid in the vertical position.
  • the arrangement of the gear housing 24 in these two positions is made possible in that the gear housing has two flat mounting surfaces 25, 26, in which bores for threaded bolts, not shown, can be provided.
  • the gear housing according to the second exemplary embodiment is mounted on semicircular profiles 27, which are received in a form-fitting manner in fillet grooves 28 of the gear housing 24.
  • the fillet groove 28 is provided in the mounting surface 25, while the fillet groove 29 is provided in the mounting surface 26.
  • 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. When the transmission is assembled, 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.
