A casing for a shaft assembly, a shaft assembly, a method of forming a casing, and a drive assembly. The casing may generally include a liner defining a central passage and having a body and an outwardly-extending leg (e.g., extending circumferentially about and/or axially along the body), and a cover extending circumferentially about and axially along the liner.

F16C 1/06 - Flexible shaftsMechanical means for transmitting movement in a flexible sheathing for conveying rotary movements with guiding-sheathing, tube, or box
A system for mechanically transmitting power from a common rotational drive shaft of a seeding implement to a geared outer periphery of a seed meter. The system includes a first transmission that connects to common rotational drive shaft, a flexible drive shaft coupled to the first transmission, and a second transmission coupled to the opposite end of the flexible drive shaft. A clutch assembly connects to a flexible drive shaft assembly to selectively allow power to be transmitted from the first transmission to the second transmission. The second transmission connects to the periphery of the seed meter. The seed plate of the seed meter includes a circumferential gear along a periphery to be driven by the second transmission.
An apparatus for transmitting power from a drive shaft (24) to a seed meter shaft of a seed metering device includes a transmission (26). A transmission housing (28) has a first housing section (30) and an identical second housing section (30). The first housing section (30) and the second housing section (30) together define a first internal passageway (44) and a second internal passageway (50). The transmission further includes a first transmission element (46) rotatably supported by the first housing section (30) and the second housing section (30) in the first internal passageway (44). The first transmission element (46) connects to one of the drive shaft (24) and the seed meter shaft. The transmission further includes a second transmission element (54) rotatably supported by the first housing section (30) and the second housing section (30) in the second internal passageway (50). The second transmission element (54) engages the first transmission element (46) and connects to the other of the drive shaft (24) and the seed meter shaft.

A system for transmitting power from a drive shaft to a seed meter shaft of a seeder is disclosed. The system comprises a first transmission that connects to one of the drive shaft and the seed meter shaft. The first transmission also connects to a clutch assembly. The clutch assembly connects to a flexible drive shaft assembly, and the flexible drive shaft assembly connects to a second transmission. The second transmission connects to the other of the drive shaft and the seed meter shaft. The clutch assembly is detachable from the first transmission and the flexible drive shaft assembly and the flexible drive shaft assembly is directly connectable to the first transmission.
