    • A wave gear drive (1) has a silk-hat shaped flexible external gear (12) comprising a cylindrical body (13), a circular diaphragm (14), a circular boss (15) formed integrally on the diaphragm (14), and external teeth (16) formed on the body (13) at a side of an open end (13a) thereof. The boss (13) of the flexible external gear, a cross roller bearing (7) and the rigid internal gear (11) are arranged between first and second end plates (2, 3) so as to define a substantially sealed inside space of the wave gear drive (1). A resilient seal ring member (8) is mounted on the open end (13a) of the flexible external gear to divide the inside space into an inside portion (9) where a first lubricant having a high viscosity is supplied and an outside portion (10) where a second lubricant having a low viscosity is supplied. These lubricants are prevented from being mixed with each other during operation, thus proper lubrication to portions of the teeth (11a, 16) of the gears (11, 12) and to a wave bearing (19) of the wave generator (17) can be maintained.
    • 波纹齿轮传动装置(1)具有一个包括圆柱形主体(13),圆形隔膜(14),一体地形成在隔膜(14)上的圆形凸台)的丝绸形弹性外齿轮, 在主体(13)的开口端(13a)的一侧形成有外齿(16)。 柔性外齿轮的凸台(13),交叉滚子轴承(7)和刚性内齿轮(11)设置在第一和第二端板(2,3)之间,以便限定内侧空间 波齿轮传动(1)。 弹性密封环构件(8)安装在柔性外齿轮的开口端(13a)上,以将内部空间分成内部(9),在内部(9)中供应高粘度的第一润滑剂和外部部分 ),其中提供具有低粘度的第二润滑剂。 这些润滑剂在操作期间被防止彼此混合,因此对齿轮(11,12)的齿(11a,16)的部分和波发生器(17)的波浪轴承(19)的适当润滑可以 保持。

    • An externally toothed portion of a cup-shaped flexible externally toothed gear of a wave gear device is flexed into an ellipsoidal shape by a six-roller-type wave generator. A region of an inner peripheral surface of the ellipsoidally flexed externally toothed portion that is positioned on a major axis of the ellipsoidal shape is maximally inclined. First rollers of the wave generator are arranged so that the incline is identical to the incline of the region of the inner peripheral surface. A circular outer peripheral surface of the first rollers can be brought into contact with the region of the inner peripheral surface in an external-tooth tooth-trace direction without deflection; therefore, the angular transmission precision of the wave gear device can be improved.
    • 波轮齿轮装置的杯形柔性外齿轮的外齿部分通过六辊式波发生器弯曲成椭圆形。 位于椭圆形长轴上的椭圆形外齿部的内周面的区域最大地倾斜。 波浪发生器的第一辊布置成使得倾斜与内周表面的区域的倾斜度相同。 第一辊的圆形外周面可以在外齿齿迹方向上与内周面的区域接触而不偏转; 因此,能够提高波齿轮装置的角度传递精度。

    • Disclosed is a wave-type linear motion mechanism including a hydraulic pressure chamber for applying a retention force in the axial direction to a rigid screw member which moves in a linear fashion. Regulating valves are provided in the hydraulic pressure chamber, and these regulating valves open during the rotation of a wave generator so that no hydraulic pressure is exerted on the rigid screw member which moves in a linear fashion. During the rotation of the wave generator the regulating valves close to establish an airtight state in the hydraulic pressure chamber, and a hydraulic pressure is exerted as a retention force on the rigid screw member. Although restricted by the meshing strength between the rigid screw member and a flexible screw member and the buckling strength of the flexible screw member, the retention force of the wave-type linear motion mechanism is able to be increased.
    • 公开了一种波形直线运动机构,其包括用于将轴向保持力施加到以线性方式移动的刚性螺钉构件的液压室。 调节阀设置在液压室中,并且这些调节阀在波发生器的旋转期间打开,使得在以线性方式移动的刚性螺钉构件上不施加液压。 在波浪发生器旋转期间,调节​​阀靠近在液压室中建立气密状态,并且作为保持力施加液压作用在刚性螺钉构件上。 虽然受到刚性螺钉构件和柔性螺钉构件之间的啮合强度和柔性螺钉构件的弯曲强度的限制,但是能够增加波形线性运动机构的保持力。
