    Abstract: A driving force transmitting device includes a first gear that rotates about the same rotational shaft as that of a small wheel portion and a second gear that engages with the small wheel portion and to which a rotational driving force is transmitted from the first gear. A rib member that rotatably supports the second gear is provided at a rotational center of the second gear. A first end portion of a rotational shaft is pivotally supported by an attachment plate within a root circle of the first gear. The annular rib member is provided on a web face of the first gear. The rib member has the same rotational shaft as the first gear and co-rotates with the first gear while supporting a second end portion of the rotational shaft.

    Abstract: A gearing system using modular gear bearing components. Each component is composed of a core, one or more modules attached to the core and two or more fastening modules rigidly attaching the modules to the core. The modules, which are attached to the core, may consist of gears, rollers or gear bearing components. The core orientation affects the orientation of the modules attached to the core. This is achieved via the keying arrangement of the core and the component modules that attach to the core. Such an arrangement will also facilitate the phase tuning of gear modules with respect to the core and other gear modules attached to the core.

    Abstract: This invention obviates the need for an end roller in the traditional gear bearing design without giving up the desired bearing functions. The preferred embodiment of the partial gear bearing of the invention includes an upper half, comprising peak partial teeth, and a lower, or bottom, half, comprising valley partial teeth. The upper half also has an integrated roller section between each of the peak partial teeth with a radius equal to the gear pitch radius of the radially outwardly extending peak partial teeth. Conversely, the lower half has an integrated roller section between each of the valley half teeth with a radius also equal to the gear pitch radius of the peak partial teeth. The valley partial teeth extend radially inwardly from its roller section. The peak and valley partial teeth are exactly out of phase with each other, as are the roller sections of the upper and lower halves. Essentially, the end roller bearing of the typical gear bearing has been integrated into the normal gear tooth pattern.

    Abstract translation: 本发明避免了在传统齿轮轴承设计中需要端辊，而不会放弃所需的轴承功能。 本发明的部分齿轮轴承的优选实施例包括上半部，包括峰部分齿，以及包括谷部分齿的下部或底部半部。 上半部还在每个峰部分齿之间具有一个整体的辊部分，其半径等于径向向外延伸的峰部分齿的齿距半径。 相反地​​，下半部在每个谷半圆之间具有一个整体的辊部分，其半径也等于峰部分齿的齿距半径。 谷部分齿从其辊部分径向向内延伸。 峰部分和谷部分齿彼此正好相异，上半部和下半部分的辊部分也是如此。 基本上，典型齿轮轴承的端滚子轴承已经集成到正常齿轮齿形中。

    Abstract: A gear drive mechanism with two rotary gears meshing with each other has a first friction rim surface rotationally coupled to one of the two gears and a second friction rim surface rotationally coupled to the other of the two gears. The friction rim surfaces are in mutual contact with each other and thereby enabled to transmit a friction-based torque between each other.

    Abstract: A gear bearing having a first gear and a second gear, each having a plurality of teeth. Each gear operates on two non-parallel surfaces of the opposing gear teeth to perform both gear and bearing functions simultaneously. The gears are moving at substantially the same speed at their contact points. The gears may be roller gear bearings or phase-shifted gear bearings, and may be arranged in a planet/sun system or used as a transmission.
