- 軸線方向に互いに離間した領域にて内側の管状部材に係合するように支承面によって第1の支承リング部及び第2の支承リング部を支持するハウジングを備える支承装置において、
前記第1の支承リング部及び前記第2の支承リング部が、径方向に自由に曲がる単一の支承リングによって設けられ、前記単一の支承リングは、前記第2の支承リング部が荷重を受けて径方向に自由に曲がりそのときに前記第2の支承リング部の支承面が前記第1の支承リング部よりも直径が大きい部分を呈するように、支持され、前記単一の支承リングは、テーパ状にされたベースを有する前記ハウジングの溝内に取り付けられることを特徴とする、支承装置。 - 前記別個独立の複数の支承リングがそれぞれ、前記ハウジング内の別個独立の溝に配置され、前記溝のうちの一方の直径が他方のものの直径よりも大きい、請求項1に記載の支承装置。
- 前記ハウジングが管状の内面を有し、該内面から前記支承リングが径方向に突出し、前記内面のうちの、前記支承面の直径が大きい前記支承リングに隣接する、前記ハウジングの軸線方向の一端部にある部分が、使用時の前記管状部材の横方向の曲げを吸収するために切り取られている、請求項1又は2に記載の支承装置。
- 3つ以上の支承リングが、軸線方向に互いに離間し、前記ハウジングの軸線方向の端部に向かって、ある支承リングから次の支承リングに直径が徐々に大きくなる支承面を有するように、前記ハウジング内に設けられ取り付けられている、請求項1〜3のいずれか一項に記載の支承装置。
- 支承面の直径が大きい1つ又は複数の支承リングが、直径が小さい支承面の1つ又は複数の内側支承リングの各側に配置される、請求項1〜4のいずれか一項に記載の支承装置。
- 前記単一の支承リングのハウジングが管状の内面を有し、該内面から前記支承リングが径方向に突出し、前記内面のうちの、径方向に曲がることが可能な前記支承リング部に隣接する、前記単一の支承リングのハウジングの軸線方向の一端部にある部分が、使用時の前記管状部材の横方向の曲げを吸収するように切り取られている、請求項1に記載の支承装置。
- 前記単一の支承リングから軸線方向に離間し、前記第1の支承リング部と直径が同じか又はそれよりも直径が大きい支承面を有する、追加の支承リングを含む、請求項1又は6に記載の支承装置。
- 前記単一の支承リングからなる前記第1の支承リング部が、一方の側で軸線方向に離間した前記第2の支承リング部と、他方の側で軸線方向に離間した第3の支承リング部とを有し、前記第2の支持リング部及び前記第3の支承リング部が両方とも、荷重を受けて径方向に自由に曲がり、もって、それぞれの支承面が前記第1の支承リング部よりも直径が大きい部分を呈する、請求項1、6又は7に記載の支承装置。
- 前記ハウジングから取り除いたときに、前記別個独立の支承リングが互いに同一であるか、又は前記単一の支承リングが、前記追加の支承リングと同一である、請求項1〜5又は7のいずれか一項に記載の支承装置。
- 前記別個独立の支承リングがそれぞれ、その直径を通る中心の面を中心に対称である、請求項1〜9のいずれか一項に記載の支承装置。
- 当該支承装置内で支持された管状部材を含む、請求項1〜10のいずれか一項に記載の支承装置。
- 請求項1〜11のいずれか一項に記載の支承装置を有する、航空機の着陸装置にあるショックアブソーバの支柱。
- 請求項12に記載の航空機の着陸装置にあるショックアブソーバの支柱を含む航空機。
