APPARATUS FOR EQUALIZING THE TENSIONS AMONG ELEVATOR WIRE ROPES
Document Type and Number:
WIPO Patent Application WO/2010/131876
Kind Code:
A2
Abstract:
The present invention relates to an apparatus for equalizing tensions among elevator wire ropes, which immediately eliminates imbalance and equalizes the tensions among elevator wire ropes in the event of differences in the lengths of elevator wire ropes, to thereby improve safety, durability and reliability. The apparatus of the present invention automatically corrects imbalance caused by changes in the lengths of a plurality of elevator wire ropes (700) to maintain a balance in the tensions of elevator wire ropes, and comprises: a main body (200f), the interior of which has an accommodation space; tension adjustment means coupled to a plurality of belts (10f, 20f, 30f, 40f) connected to the elevator wire ropes (700), respectively, and arranged in the main body (200f); a main rotary shaft (50f) which penetrates through the tension adjustment means and which is rotatably coupled to the main body (200f); and first and second external gears (45f, 48f) which are fixed at the main rotary shaft (50f) such that the gears (45f, 48f) are rotatable, and which are coupled to the front and rear surfaces of the tension adjustment means to transmit rotating forces.
