| Zusammenfassung: | The utility model discloses a swing-typed guide screw elevator. A rotating part (4) of the elevator and a transmission nut (3) implement transmission fission-typed structure by a drum-shaped gear (5); two ends of the transmission nut (3) are supported by a sphere bearing (2). The utility model has the advantages of simple structure, cheap cost, allowing the end part of the guide screw to have a certain radial displacement, effectively avoiding the attached load in the vertical lifting direction, relatively reducing the installation precision, prolonging the service life of the elevator, and enlarging the applicable range. |
