Title: (EN) LOAD DETECTOR
(ZH) 载荷检测器
Abstract: front page image
(EN) This load detector is provided with: a holding unit which comprises an inner ring part holding a shaft that supports a load, an outer ring part that is provided so as to surround the inner ring part and that is fastened to a mounting member by a fastening member through a plurality of mounting holes formed at intervals in a circumferential direction, and a spring part that is connected to the outer ring part at a spring part end radially extending from the inner ring; and a displacement detection unit which detects displacement of the inner ring part caused by a load. A mounting fixation portion which is a joint surface, of the fastening member, relative to the outer ring part is disposed at the circumferential edge of each of the mounting holes. In the outer ring part, a low-rigidity portion is formed between the mounting hole and the spring part end, and the low-rigidity portion has bending rigidity, in the circumferential direction, lower than that of other portions of the outer ring part.
(ZH) 载荷检测器具有:保持单元,其由内圈部、外圈部及弹簧部构成,该内圈部保持对载荷进行支撑的轴,该外圈部将该内圈部包围而设置,通过在周向隔着间隔而形成多个的安置孔,由紧固部件而紧固于安置部件,该弹簧部在从内圈部向径外侧方向延伸的弹簧部端与外圈部连接;以及位移检测部,其对通过载荷而产生的内圈部的位移进行检测。在安置孔的周缘部具有紧固部件的相对于外圈部的接合面即安置固定部。在外圈部,在安置孔和弹簧部端之间形成有低刚性部,低刚性部的周向的弯曲刚性低于外圈部的其他部位的弯曲刚性。
