PROBLEM TO BE SOLVED: To provide an elevator sheave uneven wear automatic adjuster that can easily suppress a variation of tension between respective ropes.SOLUTION: An elevator sheave uneven wear automatic adjuster includes: a plurality of sheaves 61 each around which a rope 3 is wound and of which radial dimension is variable; and a sheave radial dimension adjustment device 62 for varying a radial dimension of each of the sheaves 61 in a direction in which tension of the respective ropes 3 comes close to each other. Each of the sheaves 61 has four divided sheave pieces 611 juxtaposed to separate from each other in the circumferential direction. The sheave radial dimension adjustment device 62 varies a dimension of a gap between the divided sheave pieces 611 adjacent to each other, so as to vary the radial dimension of the sheave 61.SELECTED DRAWING: Figure 2
【課題】それぞれのロープにおける張力のばらつきを簡単に抑制することができるエレベータ用綱車偏摩耗自動調整装置を得る。【解決手段】それぞれにロープ3が巻き掛けられ、径方向寸法が変化可能な複数の綱車61と、それぞれのロープ3における張力が互いに近づく方向にそれぞれの綱車61の径方向寸法を変化させる綱車径寸法調整装置62とを備え、それぞれの綱車61は、周方向に離れて並べて設けられた4個の分割綱車片611を有し、綱車径寸法調整装置62は、周方向に隣り合う分割綱車片611の隙間の寸法を変化させることによって、綱車61の径方向寸法を変化させる。【選択図】図2
