- 内周に軌道面を有する外輪と、外周に軌道面を有する内輪と、内・外輪の軌道面間に配置された複数の中空ころと、中空ころを周方向等間隔に保持する保持器とを具備し、前記保持器が、対向配置された第1環状部材及び第2環状部材と、周方向の複数箇所に配置され、一対の環状部材を相互に連結するピンとを備え、前記ピンの軸部の一端に頭部を設け、第1環状部材を貫通したピンの軸部の他端を中空ころに挿通し、さらに第2環状部材とねじ結合することで、前記一対の環状部材同士が連結されると共に、該中空ころが一対の環状部材で回転自在に支持されるころ軸受において、
前記ピンの頭部を、軸部の他端を第2環状部材にねじ結合する際の締め込み力を与える部分として、この頭部を軸部と一体とし、中空ころの内周にパイプ材を配置し、中空ころをパイプ材に対して回転可能とし、第1環状部材に軸部の外周面と隙間を介して対向する貫通孔を設け、ピンの軸部を、第1環状部材の貫通孔およびパイプ材の内周に挿入して第2環状部材にねじ結合し、パイプ材の両端面を第1環状部材および第2環状部材に当接させ、前記ピンの頭部とこれに対向する第1環状部材との間に、ピンが挿通される座金を配設し、第1環状部材に対する座金の回り止め、および座金に対するピンの回り止めをそれぞれ設け、両回り止めのうち、少なくとも座金に対するピンの回り止めを解除可能としたことを特徴とするころ軸受。 - 前記座金に対するピンの回り止めを、座金を塑性変形させ、塑性変形した部分をピンの頭部と係合させることにより行う請求項1記載のころ軸受。
- 前記座金に爪部を設け、ピンを第2環状部材とねじ結合した後で爪部を加締めて、爪部をピンの頭部に係合させることにより、座金に対するピンの回り止めを行う請求項2記載のころ軸受。
- 前記第1環状部材に対する座金の回り止めを、座金を第1環状部材の内周面と外周面の何れか一方または双方と係合させることで構成した請求項1〜3の何れか1項に記載のころ軸受。
- 前記第1環状部材に対する座金の回り止めを、座金の複数箇所にピンを挿通することで構成した請求項1〜3の何れか1項に記載のころ軸受。
- 前記中空ころとして円錐ころを用いた請求項1〜5の何れか1項に記載のころ軸受。
