Abstract
An elevator machinery (1) with a disc type motor is mounted on one of the guide rails (6) of the elevator car or counterweight. The guide rail (6) constitutes a part adding to the mechanical strength of the elevator machinery. The vertical forces applied to the traction sheave (4) by the elevator ropes are passed to the guide rail (6) via the rolling center of a bearing. The elevator machinery is provided with a damping system to absorb vibrations and oscillations. The elevator machinery (1) of the invention is light in weight, needs only a small space when mounted and is inexpensive to manufacture.
Claims82
A drive machinery for an elevator, said elevator including a counterweight and elevator ropes, said machinery comprising an elevator motor, a traction sheave driving the elevator ropes, and a guide for at least one of the elevator and counterweight, the guide extending in a longitudinal direction which is a same direction as a direction of travel of the counterweight, the guide having a longitudinal side, said elevator motor having a stator, a rotor, a motor shaft and at least one bearing between the rotor and the stator, the elevator motor being mounted on the longitudinal side of the guide.
A drive machinery for an elevator, said elevator including a counterweight and elevator ropes, said machinery comprising an elevator motor, a traction sheave driving the elevator ropes and a guide for at least one of the elevator and counterweight, the guide having a top and bottom and, said elevator motor having a stator, a rotor, a motor shaft and at least one bearing between the rotor and the stator, the elevator motor being mounted on said guide below the top thereof.
A drive machinery for an elevator, said elevator including a counterweight and elevator ropes, said machinery comprising an elevator motor, a traction sheave driving the elevator ropes and a guide for at least one of the elevator and counterweight, the guide having a top end and a bottom end, said elevator motor having a stator, a rotor, a motor shaft and at least one bearing between the rotor and the stator, the elevator motor being mounted on the guide between the ends thereof.
A drive machinery for an elevator, said elevator including a counterweight and elevator ropes, said machinery comprising:
- a guide for at least one of the elevator and counterweight;
- an elevator motor and a traction sheave driving the elevator ropes, said elevator motor having a stator, a rotor, a motor shaft and at least one bearing between the rotor and the stator, the elevator motor being mounted on the guide;
- at least one vibration damping element between the elevator motor and the guide;
- and
- an auxiliary frame, the damping element being attached to the stator and the guide via the auxiliary frame in such a manner that the auxiliary frame is attached to the stator, and the damping element is placed between the auxiliary frame and the guide.
A gearless traction sheave drive assembly for an elevator, said elevator including a counterweight, an elevator car and elevator ropes, the elevator ropes extending between at least the counterweight and the elevator car, said drive assembly comprising:
- a motor having a sheave for driving the elevator ropes;
- and
- a guide for at least one of the elevator and counterweight which move along the guide, the motor being attached to the guide with the guide having a guiding surface, the guide extending laterally from the motor towards the guiding surface.
A gearless traction sheave drive assembly for an elevator, said elevator including a counterweight, an elevator car and elevator ropes, the elevator ropes extending between at least the counterweight and the elevator car, said drive assembly comprising:
- a motor having a sheave for driving the elevator ropes;
- and
- a guide for at least one of the elevator and counterweight which move along a longitudinal side of the guide, the motor being attached to the longitudinal side of the guide with the guide being between the elevator car and the counterweight.
