Abstract
Radial and axial bearing devices in which loads are transmitted from a race through circularly disposed rotating elements which are positioned relative to the race by a second and possibly a third set of rotating elements which in turn are held in position by retainers, which also constitute the other bearing race. All of these elements are in rolling contact with one another, so friction is minimized. Some of the devices are simply bearings, others are capable of rolling contact speed changes, and yet others are capable of rolling contact oscillatory motion and torque transmission through gear teeth.
Claims19
A rooling device comprising:
- a bearing race having at least one circularly oriented surface,
- first rotating means,
- said first rotating means including at least two rotating elements in rolling contact with said circularly oriented surface of said bearing race,
- second rotating means for positioning said first rotating means relative to said circularly oriented surface of said first bearing race,
- said second rotating means including at least two generally roller-shaped rotating elements alternately interposed between said rotating elements of said first rotating means to prevent their mutual contact and engaging the same in rolling contact,
- and two circular retainer rings respectively engaging the opposite ends of said generally roller-shaped rotating elements in rolling contact and holding the same in position,
- said retainer rings also functioning as the only bearing races for said second rotating means.
