Abstract

【課題】可撓性歯車の耐用年数と強度を大幅に高めることができるサイクロイドピン歯車波動歯車装置を提供する。【解決手段】カム軸１、可撓性軸受２、可撓性歯車３、針状ころ４及び剛性歯車５を備え、可撓性軸受が楕円形のカム軸に取り付けられ、可撓性歯車の内輪が可撓性軸受の外輪と相互に嵌合し、可撓性歯車の外歯面が各針状ころに相互に接触し、針状ころが剛性歯車の半円溝内に均一に分布し、主軸受の内輪が可撓性歯車に固定して接続され、主軸受の外輪が剛性歯車に固定して接続される。歯高さと歯元がいずれもサイクロイド歯プロフィールであり、破断故障のリスクを軽減させ、深い噛み合い距離を必要とせずに非常に大きな噛合量を得られ、歯幅が大きく、すべての歯が噛合に関与し、歯面の単位圧力が小さく、非常に大きなトルクに耐えられ、所要の可撓性歯車変形量も非常に小さい。【選択図】図１A cycloid pin gear wave gear device capable of significantly increasing the service life and strength of a flexible gear. A cam shaft, a flexible bearing, a flexible gear, needle rollers, and a rigid gear are provided, and the flexible bearing is attached to an elliptical cam shaft. The inner ring engages with the outer ring of the flexible bearing, the outer tooth surface of the flexible gear contacts each needle roller, and the needle roller is uniformly distributed in the semicircular groove of the rigid gear. The inner ring of the main bearing is fixedly connected to the flexible gear, and the outer ring of the main bearing is fixedly connected to the rigid gear. Both the tooth height and root are cycloidal tooth profiles, reducing the risk of breakage failure, obtaining a very large meshing amount without requiring a deep meshing distance, large tooth width, all teeth meshing The unit pressure of the tooth surface is small, can withstand a very large torque, and the required amount of deformation of the flexible gear is very small.
