PROBLEM TO BE SOLVED: To easily detect abrasion occurring on an inner peripheral surface of a bush of an electromagnetic brake.SOLUTION: The invention relates to an electromagnetic brake abrasion detection device which detects abrasion of a bush 22 which guides a plunger 5 of an electromagnetic brake and includes: a lighting part 30 having a luminous body 31 which is disposed below the bush 22 and radiates light to an inner peripheral surface of the bush 22; and a digital camera 36 which is disposed above the bush 22 and images the inner peripheral surface radiated by the luminous body 31. The lighting part 30 includes: a support rod 32 supporting the luminous body 31; an adjustment body 32 which is placed on an upper end of a core 2 and adjusts a height position of the support rod 32; and a lens receiver 35 on which a lens of the digital camera 36 is placed, the lens receiver 35 being fixed to an upper end of the support rod 32.SELECTED DRAWING: Figure 3
【課題】電磁ブレーキのブッシュの内周面に生じた摩耗を容易に検出できるようにする。【解決手段】本発明は、電磁ブレーキのプランジャ5を案内するブッシュ22の摩耗を検出する電磁ブレーキ摩耗検出装置であって、ブッシュ22の下方に配置されてブッシュ22の内周面を照射する発光体31を有する照明部30と、ブッシュ22の上方に配置されて発光体31によって照射された内周面を撮影するデジタルカメラ36とを備えている。照明部30は、発光体31が支持された支持棒32と、コア2の上端に載置され支持棒32の高さ位置を調整する調整体32と、支持棒32の上端に固定されてデジタルカメラ36のレンズが載置されたレンズ受け35とを備えている。【選択図】図3
