LAMINATION SPRING TYPE TORQUE HINGE AND MANUFACTURING METHOD OF THE LAMINATION SPRING TYPE TORQUE HINGE
To provide a lamination spring type torque hinge in which a sufficient amount of a lubricant is enclosed between an inner peripheral edge of a plate spring and a connection shaft and leakage of the enclosed lubricant is prevented.SOLUTION: A lamination spring type torque hinge 2 includes: a connection shaft 4 which rotatably connects a first member with a second member; three or more plate springs 6 which are laminated and into which the connection shaft 4 is press-fitted; and a rotation prevention member 8 which prevents rotation of at least a part of the plate springs 6. Recessed parts 6a recessed to the radial outer side are formed at an inner peripheral edge of at least parts of each plate spring 6 at intervals in a circumferential direction. A space between each recessed part 6a and an outer peripheral surface of the connection shaft 4 is filled with a lubricant. The recessed parts 6a of the plate springs 6 which exclude the plate springs 6 at both axial side end parts are closed by the plate springs 6 at both axial side end parts.SELECTED DRAWING: Figure 1
【課題】板バネの内周縁と連結軸との間に充分な量の潤滑剤が封入され、かつ、封入された潤滑剤の漏れが防止される積層バネ式トルクヒンジを提供する。【解決手段】積層バネ式トルクヒンジ２は、第１の部材と第２の部材とを回転自在に連結する連結軸４と、積層されて連結軸４に圧入された３枚以上の板バネ６と、板バネ６の少なくとも一部の回転を阻止する回転阻止部材８とを備える。板バネ６の少なくとも一部の内周縁には、周方向に間隔をおいて径方向外側に窪んだ複数の凹部６ａが形成されている。複数の凹部６ａと連結軸４の外周面との間には潤滑剤が充填されている。軸方向両側端部以外の板バネ６の複数の凹部６ａは、軸方向両側端部の板バネ６によって塞がれている。【選択図】図１
