摘要： PROBLEM TO BE SOLVED: To provide an oiling device for smoothly lubricating an engagement part of a transmission system.
SOLUTION: In the oiling device for supplying lubricating oil to the engagement part 1a of the transmission system, a yarn-like material 3 is wound inside a gear tooth groove 1b of the engagement part 1a, and the lubricating oil fed from inside of the engagement part 1a is supplied to the engagement part 1a through the yarn-like material 3. Since supply of the lubricating oil is restricted by the yarn-like material 3, an appropriate quantity of the lubricating oil is always supplied to the engagement part 1a, and environmental pollution due to scattering of the lubricating oil can be prevented. Since the lubricating oil adheres to the engagement part 1a after the yarn-like material 3 is impregnated with the lubricating oil once, the lubricating oil is evenly supplied to the engagement part 1a for appropriate lubrication.

摘要翻译：要解决的问题：提供一种用于平滑地润滑传动系统的接合部分的加油装置。解决方案：在用于向传动系统的接合部1a供给润滑油的上油装置中，纱线状材料3卷绕在接合部1a的齿轮齿槽1b内，并且从内部供给润滑油接合部1a通过纱线状材料3供给到接合部1a。由于润滑油的供给受到纱线状材料3的限制，因此适量的润滑油总是供给到接合部可以防止由于润滑油的散射引起的环境污染。由于在纱线状材料3浸渍润滑油一次之后润滑油粘附到接合部分1a，所以润滑油被均匀地供给到接合部分1a以进行适当的润滑。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To remove the backlash of a hypoid gear device. SOLUTION: The hypoid gear device 1 comprises a backlash removing means for removing backlash between a driven large gear 8 and a driving small gear 7 meshing with the driven large gear. The backlash removing means has a driven small gear 11 arranged coaxially on the driving small gear 7 for meshing with the driven large gear 8 and an elastic body 12 for energizing the driven small gear 11 coaxially in the opposite direction to the driving small gear 7. Because the driving small gear and the driven small gear are energized coaxially in mutually opposite directions by the elastic body, the driving small gear has contact with one toothed face of the driven large gear and at the same time the driven small gear has contact with the opposite toothed face of the driven large gear, resulting in the removal of backlash.

摘要： PROBLEM TO BE SOLVED: To provide a torque transmission device capable of efficiently transmitting torque from either of a first input shaft and a second input shaft to an output shaft side while the other of the first input shaft and the second input shaft is fixed. SOLUTION: This torque transmission device is provided with the first input shaft 1, the second input shaft 2, an output shaft 3 which is supported on a housing 4 while rotary movement around an axial line is allowed and linear movement in the direction of axial line is restricted and in which a screw is formed at an outer periphery, a first nut 5 fitted in the output shaft 3, a screw shaft 6 arranged on a central line of the output shaft 3 to form a lead different from the output shaft 3, and a second nut 7 fitted in the screw shaft 6 and connected with the first nut 5. A first transmission means 8 makes the screw shaft 6 perform linear movement in the direction of axial line by rotary movement of the first input shaft 1. A second transmission means 9 makes the second nut 7 move so as to draw a spiral by rotary movement of the second input shaft 2.
