Abstract

The present invention relates to an elevator traction machine, and more particularly, to an elevator traction machine, wherein a plurality of planetary gears are coupled to be circumscribed and engaged with a sun gear formed at one end of a driven shaft in order to reduce high speed rotation transmitted from a driving motor and to wind wires on a sheave, and pinions formed at the other sides of the planetary gears are circumscribed and engaged with a plurality of other planetary gears or a fixed sun gear so that planetary gears just before the fixed sun gear can be rotated together with a flange, thereby obtaining reduction effects for a gear ratio among the sun gears, pinions and planetary gears, and noise / vibration-reducing effects and large rotational force-transmitting effects due to formation of the gears out of helical gears.

Description

technical field

[0001] The present invention relates to elevator traction machines, and more particularly, to elevator traction machines in which a plurality of planetary gears are connected to circumscribe and mesh with a sun gear formed at one end of a driven shaft, thereby reducing The high-speed rotation transmitted by the motor and winds the rope on the sheave, and on the other side of the planetary gear forms a pinion that circumscribes and meshes with multiple other planetary gears or a fixed sun gear, so that the planetary gear just before the fixed sun gear It can rotate together with the flange, thereby obtaining the effect of reducing the transmission ratio between the sun gear, the pinion gear and the planetary gear, the effect of reducing noise / vibration, and the effect of obtaining a large rotational force transmission due to the gear construction of the helical gear. Background technique

[0002] Usually, the elevator is provided with a traction machine on the...
