Abstract
【解決手段】 内外輪1,2間の軸受空間をシール5で密封した軸受において、前記シール5に、その芯金6をアンテナとするICタグ9を取付ける。シール5は、芯金6を有するゴムまたは樹脂製のものである。
【選択図】 図1
Description
各種物品に取付けられて、小型で多量の情報記録を可能としたものとしては、RFID(無線周波数認識)技術を応用したRFID用ICタグが種々開発されている(例えば、特許文献1)。
このため、情報量の多いRFID用ICタグを軸受に取付けることを考えた。しかし、RFID用ICタグは読み取りにマイクロ波を利用しているため、軸受に直接にRFID用ICタグを取付けると、読み取り時にマイクロ波を軸受の軌道輪等が吸収し、RFID用ICタグの読み取りが不能になる。すなわち、軸受の内輪あるいは外輪にアンテナ付ICタグを直接に取付けた場合、アンテナ以外の金属である内輪および外輪、実機に組み込んだ際の軸受ハウジングやその他の金属部材によってマイクロ波が吸収されることによる障害が起こる。そのためICタグの記憶情報の読み取りが困難となる。ICタグ自体に、金属部品に直接に取付けられるように工夫を施したものもあるが、ICタグが高価でかつ大きくなってしまう。
この発明の他の目的は、ICタグ自体にアンテナが不要で、ICタグの小型大容量化が得られるICタグ付軸受およびそのシールを提供することである。
この構成によると、シールの芯金をアンテナとして利用するため、ICタグにアンテナを設けることが不要で、ICタグが小型で大記憶容量のものとできる。芯金は、シールのゴムまたは樹脂の部分で軌道輪に対して絶縁されているため、軌道輪による電波吸収や反射の障害が防止され、ICタグの記憶情報の読み取りが良好に行える。また、ICタグをシールに取付けるため、軌道輪に取付ける場合に比べて製造が容易である。
この構成のICタグ付軸受用シールによると、この発明のICタグ付軸受について説明したと同様に、軌道輪等による電波の反射の障害や吸収を防止できて、記憶情報の読み取りが良好に行え、かつICタグ自体にアンテナが不要で、ICタグの小型大容量化が得られる。そのため、小型のシールであっても、取付スペース上の問題を生じることなく、ICタグ付きのシールとすることができる。
金属製の非接触シールの場合、取付側の軌道輪に対して金属同士で接触して取付けられるため、アンテナ付きのICタグを非接触シールに直接に取付けると、電波吸収による読み取り困難の問題が生じる。しかし、この発明のように絶縁部材を介してアンテナ付きのICタグを取付けることで、ICタグの情報の読み取りが、軌道輪等による電波吸収の障害を生じることなく、良好に行える。
この発明の他のICタグ付軸受は、金属製の非接触シールにより、軌道輪間の軸受空間を密封した軸受において、前記シールに、アンテナ付きのICタグを、絶縁部材を介して取付けたものであるため、軌道輪等による電波の反射や吸収の障害を防止できて、記録情報の読み取りが良好に行える。
図4(B)に示す絶縁部材21は、アンテナ20の裏面の全面に設けられて、アンテナ20と接着される。例えば、これらアンテナ20、ICチップ9a、および絶縁部材21が一体化された部品である絶縁部材付きICタグ22が、シール5Aに接着される。
この実施形態におけるその他の構成は第1の実施形態と同じであるので、対応部分に同一符号を付してある。図5に図4(B)を正面からみた図を示す。
