Description
図1~図3に示されるように、実施の形態1に係る軸受装置100は、第1軸受1a、第2軸受1b、外輪間座6および内輪間座7、ならびに予圧センサ10を主に備える。軸受装置100は、主軸11をハウジング8に対して回転可能に支持するように設けられている。第1軸受1aおよび第2軸受1bには、例えば定位置予圧が付与されている。
予圧センサ10は、第1方向に作用する圧力に応じて直流抵抗が変化する感圧パターン部22cと、感圧パターン部22cを覆う被覆部21,23と、第1方向において被覆部21,23に隣接して配置されている緩衝部30とを備える。緩衝部30を構成する材料の縦弾性係数は、被覆部21,23を構成する材料の縦弾性係数未満である。
図8および図9に示されるように、実施の形態2に係る軸受装置101は、実施の形態1に係る軸受装置100と基本的に同様の構成を備えるが、外輪間座6の第2間座部材62が上記軸方向に突出している突出部62pを有しており、突出部62pの頂面が第3端面62aを構成している点で異なる。言い換えれば、実施の形態2に係る軸受装置101は、突出部62pの頂面が予圧センサ10の第1面20aと接する第5面として構成されている点で、軸受装置100と異なる。なお、図8および図9では、第1端子部22a、第2端子部22b、感圧パターン部22c、および被覆部21,23の図示が省略されている。また、図8では、位置決め部材63の図示が省略されている。
図11および図12に示されるように、実施の形態3に係る軸受装置102は、実施の形態1に係る軸受装置100と基本的に同様の構成を備えるが、予圧センサ10の第2面30aが第2軸受1bの外輪2bに接するように配置されている点で異なる。言い換えれば、実施の形態3に係る軸受装置102は、外輪2bの上記軸方向の端面2cが予圧センサ10の第2面30aと接する第6面として構成されている点で、軸受装置100と異なる。なお、図11では、第1端子部22a、第2端子部22b、感圧パターン部22c、および被覆部21,23の図示が省略されている。
