Abstract
An elevator installation includes a drive unit moving a car and a counterweight in an elevator shaft. The drive unit has a drive motor and a brake coupled to a drive shaft and mounted on a crossbeam in the elevator shaft or on the shaft ceiling. The drive unit has two spaced-apart drive zones and the drive motor is arranged to the left or the right of the two drive zones with the brake on the same side or the opposite side of the drive zones.
Claims14
A drive unit for an elevator installation having a car and a counterweight movable in a shaft, the car being guide along a car guide rail, the counterweight being guided along a counterweight guide rail, the car and the counterweight being connected and supported by a drive means, the drive means being drivingly coupled to the drive unit, the drive unit comprising:
- a single drive motor;
- a brake;
- a drive shaft;
- and
- at least two neighbored drive zones,
- said at least two neighbored drive zones, said brake and said single drive motor being drivingly coupled to said drive shaft,
- said at least two neighbored drive zones interacting with the drive means to drive the drive means,
- said at least two neighbored drive zones being mutually spaced at a predetermined spacing,
- said drive motor and said brake being arranged outside of said predetermined spacing,
- wherein the drive unit includes a central bearing supporting said drive shaft, and said central bearing acts transverse to a longitudinal axis of said drive shaft and rotatably supports said drive shaft at a plane of symmetry between said at least two neighbored drive zones.
An elevator installation comprising:
- a car;
- a counterweight;
- a drive unit;
- said car being arranged movably in an elevator shaft and being guided along a car guide rail, said car guide rail having a foot section and said foot section defining a width of a rail foot of said car guide rail;
- said counterweight being arranged movably in the elevator shaft and being guided along a counterweight guide rail;
- said car and said counterweight being connected and supported by a drive means, said drive means being drivingly coupled to said drive unit, said drive unit being mounted on one of a crossbeam attached to said guide rails and a ceiling of the elevator shaft;
- and
- said drive unit comprising:
- a single drive motor;
- a brake;
- a drive shaft;
- and
- at least two neighbored drive zones,
- said at least two neighbored drive zones, said brake and said single drive motor being drivingly coupled to said drive shaft,
- said at least two neighbored drive zones interacting with said drive means to drive said drive means,
- said at least two neighbored drive zones being mutually spaced at a predetermined spacing,
- said drive motor and said brake being arranged outside of said predetermined spacing,
- wherein said drive unit includes a central bearing supporting said drive shaft, and said central bearing acts transverse to a longitudinal axis of said drive shaft and rotatably supports said drive shaft at a plane of symmetry between said at least two neighbored drive zones.
