Claims (3)
- 転がり玉軸受の定圧予圧装置において、
中空であって弾性方向両側に開口を有する弾性部材と、前記弾性部材の両側の開口のそれぞれに挿入する2つのホルダーとを備え、
前記ホルダーが、前記弾性部材の開口に挿入したときに該挿入した開口の端部に当接して該弾性部材の弾性方向への延びを係止する鍔部と、前記弾性部材の反対側の開口から挿入した他のホルダーと係合して該他のホルダーとの離間を係止する爪部とを有し、
前記弾性部材の両側から挿入した前記ホルダー同士が前記爪部によって係合して、前記弾性部材を自由長より短く、且つ、予圧に必要な荷重を得られる長さに保持するとともに、前記弾性部材は前記ホルダーから露出して予圧装置を構成し、
前記予圧装置によって前記転がり玉軸受に予圧をかけるとき、前記弾性部材の弾性方向外側から前記ホルダーを押圧することで前記弾性部材を圧縮して前記ホルダー同士の前記爪部の係合が離れて、前記転がり玉軸受が該転がり玉軸受の外輪でのみ前記予圧装置と接触することを特徴とする転がり玉軸受の予圧装置。 - 前記転がり玉軸受と、前記転がり玉軸受の予圧装置は、円筒状の軸受ライナーの内周面に配置され、前記弾性部材の両側の前記ホルダーのうち、片側の前記ホルダーの外周面が、軸受ライナーの内周面と嵌合固定することを特徴とする請求項1に記載の転がり玉軸受の予圧装置。
- 請求項1または請求項2に記載の転がり玉軸受の予圧装置を有するモータ。
