Provided is a tension balancer for an overhead line, the tension balancer being capable of increasing the stroke length within a set load range by reducing the hysteresis loss of deflection-load characteristics. The tension balancer for overhead lines is provided with: a plurality of tube members arranged coaxially, including at least an outer tube member (101) and an inner first intermediate tube member (102) arranged coaxially with a gap in the radial direction; an outer coil spring (105) that applies an elastic force to the movement of the first intermediate cylinder member (102) in the axial direction with respect to the outer cylinder member (101); an outer spring washer (102a) that supports the outer coil spring (105); and a support member (201) that slidably supports the outer cylinder member (101) and the first intermediate cylinder member (102) in the axial direction. The support member (201) rotatably supports the ball (201b) and causes a portion of the ball (201b) to protrude further toward the outer cylinder member (101) than the outer spring washer (102a).
提供一种架空线用张力平衡器,该架空线用张力平衡器通过降低挠度‑载荷特性的滞后损失,能够在所设定的载荷范围内增大行程长度。是具备下者的架空线用张力平衡器:以同轴状配置的多个筒部件,其至少包括以沿径向方向具有间隙的状态以同轴状配置的外侧筒部件101和内侧的第1中间筒部件102;外侧线圈弹簧105,其针对第1中间筒部件102相对于外侧筒部件101向轴向方向的活动赋予弹性力;外侧弹簧垫圈102a,其支撑外侧线圈弹簧105;以及支撑部件201,其沿轴向方向可滑动地支撑外侧筒部件101和第1中间筒部件102。支撑部件201将滚珠201b旋转自由地支撑,使滚珠201b的一部分比外侧弹簧垫圈102a更向外侧筒部件101侧突出。
