Roller bearing gear system |
November 8, 1988 |
| An anti-friction worm-wheel assembly wherein the anti-friction elements are ollers carried by the worm element. The rollers sequentially move through grooves in the edge surface of the wheel element to transmit drive forces from one element to the other. Aims of the invention are to achie |

Concave-convex gear pair having staggered teeth |
July 14, 1987 |
| A spur gear system wherein each gear comprises two gear sections; gear te in the respective sections are staggered a one half tooth pitch distance. The effect is to achieve a relatively high contact ratio with relatively small diameter gears. Teeth on mating gears are of positive (c |

Tapered roller bearing |
April 7, 1987 |
| A resilient hollow annular frustro-conical roller bearing whose wall thicss varies according to the roller diameter. Any abnormal load placed upon the roller causes an increase area of contact between the roller and the opposing race surfaces. The hollow annular construction of the bear |

Inertia transmission |
May 27, 1986 |
| A power transmission that uses inertia forces. The drive member carries a urality of high density rollers that are acted on by centrifugal force. The driven member includes reaction surfaces that periodically move the high density rollers inwardly in opposition to the centrifugal force. |
