Lateral oscillation vibration suppressing device for elevator

Abstract

Abstract PURPOSE:To prevent the lateral oscillation of a cage even if the shift in the lateral direction of a guide rail is generated, by installing a subrail engagement element which guides the cage and engaged with a guide rail through a damper, onto the outside of at least one between a pair of rail engagement elements. CONSTITUTION:A subrail engagement element 9 installed at a prescribed position on the outside of at least one between a pair of rail engagement elements 7 performs guide, following the bending deflection of a guide rail 10, even if a bending deflection is generated on the guide rail 10, by increasing the pitch P between the rail brackets 11 and 11 for fixing the guide rail 10. Therefore, as the pitch P between the rail brackets 11 and 11 is increased, the prescribed position of the subrail engagement element 9 can be selected so that the rail engagement element 7 can be engaged in the vicinity of the min. value, for the lateral oscillation of the guide rail 10. Therefore, the vibration energy can be sufficiently absorbed according to the bending deflection of the guide rail 10, by the operation of a damper 12 which the subrail engagement element 9 is provided with.
