Disclosed is an apparatus for automatically equalizing tensions of elevator wire ropes by which an unbalance of tensions of elevator wire ropes can be immediately solved to automatically equalize the tensions in real time when lengths of the wire ropes become different, improving safety, durability, and reliability. The apparatus according to the present invention includes a body (100) having an accommodation space therein, a tension adjusting unit connected to elevator wire ropes (R1˜R4) and installed within the body (100), a main shaft (200) passing through the tension adjusting unit and rotatably coupled to an inner side of the body (100) horizontally; and first to fourth guide rollers (B1˜B4) rotatably coupled to the body (100) such that the elevator wire ropes (R1˜R4) connected to the tension adjusting unit contact the first to fourth guide rollers (B1˜B4) at outer sides thereof. |

1. An apparatus for automatically equalizing tensions of elevator wire ropes, the apparatus comprising:
a body having an accommodation space therein; a tension adjusting unit connected to first to fourth wire ropes and installed within the body; and a main shaft passing through the tension adjusting unit and coupled to an inner side of the body to be rotatable horizontally, wherein the tension adjusting unit comprises: a first rotation unit coupled to the main shaft and having an outer peripheral surface on which the first wire rope is wound; a second rotation unit coupled to the main shaft, having an outer peripheral surface on which the second wire rope is wound, and rotated in conjunction with the first rotation unit; a third rotation unit coupled to the main shaft, having an outer peripheral surface on which the third wire rope is wound, and rotated in conjunction with the second rotation unit; and a fourth rotation unit coupled to the main shaft, having an outer peripheral surface on which the fourth wire rope is wound, and rotated in conjunction with the third rotation unit, and wherein the first rotation unit comprises: a first pulley having an outer peripheral surface on which the first wire rope is wound, and having a disk having a through-hole therein; a first planetary gear unit having a plurality of first planetary gears coupled to a front surface of the disk of the first pulley, and a plurality of second planetary gears coupled to a rear surface of the disk and only half teeth on the outer peripheral surfaces of which are engaged with the first planetary gears; a first sun gear in which the main shaft is coupled to an interior thereof, coupled to an exterior of a mounting part formed at a central portion of the first pulley, and inserted into the through-hole to be engaged with the second planetary gears; and a first outer sun gear inserted into the through-hole of the first pulley and some of teeth of which are engaged with the first planetary gears. |
