Disclosed are a transmission assembly and a lifting column. The transmission assembly includes a first screw rod, a second screw rod, a first transmission sleeve fitted over the first screw rod, and an actuating device for driving the first transmission sleeve to rotate; an end of the first screw rod proximal to the actuating device is fixed, and an end of the second screw rod distant from the actuating device is fixed; a second transmission sleeve is disposed between the first screw rod and the second screw rod, the second transmission sleeve and the first transmission sleeve are synchronously rotatable and are axially extensible and retractable relative to each other, and both ends of the second transmission sleeve are in threaded transmission connection with the first screw rod and the second screw rod, respectively. Because no inner splines are provided for the first screw rod and the second screw rod, and the two screw rods do not rotate, bearings become unnecessary, such that the transmission assembly has a simpler structure, more convenient for manufacturing and assembling.
