ABSTRACT:
A gear coupling and oil actuated synchronizing clutch is disclosed. The oil is connected to the clutch by a static seal ring freely supported on the drive shaft, next to a shaft flange. The seal ring has a piston groove containing a piston ring adjacent the flange overlying a narrower groove in the flange. Engage oil in the static seal groove forces the piston ring against the flange and holes in the piston ring conduct oil to the flange groove and then to the disc pack and clutch actuating mechanism. The disc pack has a larger inlet than outlet so that the engage oil fills the pack introducting a viscous drag to the discs and initiating action of balking mechanism. Drive pins are advanced into kidney shaped holes where they form an interium connection after synchronism and before gear engagement so that the drive gears can freely register with the driven gear.
