Abstract
Improved epicyclic gearing is disclosed. The epicyclic gearing includes first and second gear sets. Each set includes at least one rotatable gear, which rotatable gears are adjacent each other. Rigid plate means are provided which secure the adjacent rotatable gears together and maintains them on essentially parallel planes. Also disclosed is an improved bearing-seal assembly which provides maximum support to a shaft in a minimum length, which provides effective sealing.

In speed reduction gearing means comprising first and second axially spaced, epicyclic differential gear sets, each gear set including adjacently disposed rotatable gears, the improvement comprising means for coupling said rotatable gear of each gear set to said rotatable gears of the other for transmission of torque, said means for coupling including means to rigidly secure said rotatable gears on essentially parallel planes, said last named means including first and second annular dished plates each plate having a central aperture and being secured adjacent its inner periphery to a radially inward portion of its one of said adjacent rotating gears, and fastener means connecting said plates together at their outer peripheries at a location radially spaced from the connection of the inner periphery, whereby to provide a rigid unitary structure, whereby to prevent skewing of the rotating gears with respect to each other during rotation.
In speed reduction gearing having input and output shafts and a housing in which is disposed the gear members and lubricant therefore, an improved seal and bearing device journaling at least one of said shafts on said housing, said improved seal and bearing device comprising, first and second anti-friction bearing members, spacer means interconnecting said first and second anti-friction bearing members in axial spaced relationship, means to sealingly mount said spacer means in said housing with said anti-friction bearing members journaling said one shaft for rotation, and seal means interposed axially between said anti-friction bearing members sealing engaging said one shaft and said spacer means to prevent entry contaminants and escape of lubricant and said anti-friction bearing most remote from the housing being self sealed and lubricated.
