US 12,410,850 B2 · Roller bearing and gear assembly

Abstract

A roller gear and bearing assembly having roller gear bearings with semi-spherical engagement members is disclosed. Semi-spherical engagement members are offset on two distinct surfaces on roller gears, with corresponding semi-spherical receiver elements on the race of the roller gear and bearing assembly. An optional improvement to the roller gear and bearing assembly is configuring the roller gears and assembling the roller gear assembly such that the roller gear and bearing assembly will be under a pre-load and the roller gears will not lose contact with the races. A second optional improvement to the roller gear and bearing assembly uses replaceable semi-spherical engagement members are replaceable spherical rollers which fit into semi-spherical receiver elements on the roller gears.

Dependent claims

A roller gear and bearing assembly comprising:

a) A roller gear and bearing race, the roller gear and bearing race having an upper raceway and a lower raceway, the upper raceway and the lower raceway being tapered, the upper raceway and the lower raceway each having a first face and a second face, all of the first faces and the second faces having a plurality of semi-spherical receiver elements;
and,
b) A plurality of roller gears, each of the roller gears being tapered to correspond with the upper and lower raceways, each of the roller gears having a plurality of semi-spherical engagement members such that the roller gears can engage with the upper and lower raceways, allowing the roller gear and bearing assembly to rotate when driven by an input power source and deliver output power to an output device while bearing a bearing load.
