Abstract:
A two-mode, compound-split, electro-mechanical transmission that minimizes vibrations, said transmission comprising:a housing; said housing having a rigid frame capable of serving as a lateral ground to prevent lateral movement of selected rotatable members supported either directly or indirectly by said frame; said frame having a generally hollow interior cavity with a generally cylindrical interior surface; a forward grounding member rigidly secured to said frame and extending radially inwardly with respect thereto; a rear grounding member rigidly secured to said frame and extending radially inwardly with respect thereto; a rotatable input member for receiving power from a prime mover power source and delivering said power to said transmission mechanism; a rotatable output member for delivering power from said transmission mechanism; a main shaft extending axially within said fame for rotation with and with respect to both said input and said output members; bearing means not only to permit rotation of said input member with respect to said frame but also laterally to ground said input member with respect to said frame; additional bearing means not only to permit rotation of said main shaft with respect to said input member but also laterally to ground said main shaft through said input member to said housing frame; and further bearing means not only to permit rotation of said output member with respect to said frame but also laterally to ground said output member with respect to said frame.
