摘要： A variable-tooth gear with SSFT pertains to the technical fields of gearing, and variable mechanical transmissions. The variable-tooth gear is designed in accordance with "the principle of configuring variable-teeth through universally shaped SSs". The working surface is composed of a large number of thin SSs (sliding-needles) superposed on one another. The meshing tooth profiles of arbitrary shapes can be configured by the free and infinite sliding of the SSs. Since the direction of sliding of the SSs is different from the direction of forces acting thereupon, the SSs can freely deform with the current tooth profiles. The direction of the force acting upon the SS when transmitting power is perpendicular to the free-sliding direction, or the angle therebetween is within the equivalent friction angle, therefore the SS possesses the self-locking property. The tooth profile thus remains unchanged when the SSs are under stress. All the SSs form an integrally closed elastic enclosure ring, possessing the effect of "rigidity and flexibility being combined, variable-tooth being fixed". Therefore the load capacity is high, the transmission is a one-stage transmission and the transmission efficiency is high. There are only two key components, such that the structure is simple, the cost is low and the size is compact. This variable-tooth gear realizes, to the core, the concept of "continuously variable transmission via gear meshing", and can be applied to vehicles or industrial fields of high speed and large power.
摘要翻译：具有SSFT的可变齿齿轮涉及齿轮传动和可变机械变速箱的技术领域。可变齿齿轮根据“通过普通形状的SS组态可变齿的原理”设计。工作面由大量相互重叠的薄SS（滑针）组成。可以通过SS的自由和无限滑动来配置任意形状的啮合齿廓。由于SS的滑动方向与作用于其上的力的方向不同，所以SS可以随当前的齿形自由变形。当发射动力时作用在SS上的力的方向垂直于自由滑动方向，或者它们之间的角度在等效摩擦角内，因此SS具有自锁性质。当SS受到压力时，齿廓保持不变。所有的SS形成一体的闭合的弹性围环，具有“刚性和柔性组合，可变齿固定”的作用。因此，负载能力高，传输是一级传输，传输效率高。只有两个关键部件，结构简单，成本低，尺寸紧凑。这种可变齿齿轮实现了“通过齿轮啮合的无级变速器”的理念，可以应用于高速，大功率的车辆或工业领域。
