Definitions

  • This invention relates to a drive apparatus for an elevator.
  • Such an apparatus may be adapted to be installed,in a machine room above an elevator shaft or hoistway.
  • Conventional electric elevators are provided with an electric drive apparatus located above the hoistway for raising and lowering the car suspended by a main cable.
  • the car is essentially disposed in the cross-sectional center of the hoistway, and the center portion of the car is suspended by the main cable reeled on a driving sheave of the apparatus.
  • One drawback of a drive apparatus of this type is that the driving sheave is not centrally mounted and the machine room space thus projects laterally outwardly from the upper portion of the hoistway, which is undesirable from a space saving standpoint in buildings.
  • a drive apparatus for an elevator characterized by:
  • Figs. 1 to 3 show a hoistway 1 for an elevator car 15 installed in a building.
  • a machine room 2 is provided above the hoistway, and communicates therewith through holes 2b in the floor 2a of the machine room.
  • a traction drive base bed 3 is mounted on the floor 2a, and a machine bed 4 is supported on the base bed at both of its ends.
  • a base member 5 is mounted in the center of the machine room 2 on the machine bed 4 by damping members 6 made of vibration absorbing material.
  • a driving sheave 7 is centrally mounted lengthwise (Fig. 1) above the base member 5 on a transverse output shaft lla as described below.
  • a deflector sheave 8 arranged behind and below the driving sheave is journaled to a support member 9 suspended from the base member.
  • a bearing holder 10 is mounted on the base member 5 alongside the driving sheave 7.
  • a reduction gear mechanism 11 is installed on the base member 5, and is driven by an input shaft llb arranged at one end of the base member.
  • the reduction gear mechanism includes an output shaft lla, a casing llc, and first, second, third, fourth, fifth and sixth gear wheels lld through lli all of the parallel tooth type.
  • One end llk of the output shaft lla is rotatably supported by bearings llj, while its other end 11l is rotatably supported by the bearing holder 10.
  • An electric drive motor 12 mounted on the base member 5 is connected to the input shaft llb of the reduction gear mechanism by a coupling 18.
  • a concrete cinder floor 13 covers the main floor 2a.
  • a main cable 14 is reeled around the driving sheave 7 and deflector sheave 8, and passes through the holes 2b to the hoistway 1 from the machine room 2.
  • An elevator car 15 is connected to one end of the main cable, and includes a frame 15a in which a cab 15b is supported by vibration absorbing rubber members 15c.
  • a counter weight 16 is connected to the other end of the cable.
  • a brake unit 17 is provided on the input shaft llb.
  • the overall drive apparatus is substantially symmetrical on both the right and left sides of the centered driving sheave 7, whereby the apparatus can be installed in a narrow machine room 2 formed to correspond with the upper space of the hoistway 1.
  • the elevator can be set up inside a small space in buildings.
  • the drive motor 12 is independently mounted on the base member 5, it can comprise any appropriate mass produced type of motor whereby the cost of the drive apparatus is further reduced.
  • the operational flexing of the shaft is decreased and the mesh between the gears of the reduction mechanism is improved, whereby the level of vibration and noise occurring in the gear mechanism is reduced.
  • the propogation of any vibration to the hoistway 1 or to the building is minimized by the base member 5 being supported by damping member 6.
  • the propagation of vibration to the cab 15b is prevented by the cab being supported by the vibration absorbing rubber members 15c on the car frame 15a, whereby the environment created in and around the elevator is quiet and pleasing to the passengers.
  • the invention provides a bearing holder for journaling the rotating shaft of the driving sheave and disposed on one side of the sheave, and a reduction gear mechanism disposed on the other side of the sheave.
  • An electric motor for driving the input shaft of the gear mechanism is disposed at one end of a base member centrally mounting the sheave and other components, opposite a deflector sheave from which a counterweight is suspended.
