Japanese Patent JP2008513689
Kind Code:

Abstract:
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.
