Gear bearing

Neglecting clearance and assuming perfect accuracy, the engagement of bearing gears is aimed at maximum rolling with minimum sliding friction of conjugated profiles in movement.

Adjacent end faces of teeth and rollers limit the axial shift of conjugated bearing gears in plane-parallel motion.

In such a way, using bearing gears as sun, ring and more than two satellites uniformly distributed among them the entire gear bearing is arranged, and carrier may be used instead of ring or sun gearwheels, or it may act as a frame unit and transfer rotation from the satellites, whereas limitation of carrier degrees of freedom would form redundant constraints or serve as an additional basis for force distribution in the mechanism.

The implementation of gear bearings may be one-piece manufacturing or a fixed joint assembly using: screws, bracers, threaded connections, pressure coupling, soldering, welding, gluing, or friction coupling in the form of sliding safety clutch or friction connection.

The gear bearing may also be assembled from separate sectional parts or by joining with optional elastic and/or thermal deformation in the manufacturing sequence.
