Universal joints let the torque shafts have large angular changes of
alignment as they turn.
The flexible joint is an articulating spline-joint assembly that has a
male splined coupling and a female splined coupling. The couplings are
connected together with a swaged retainer to make a movable joint. The
flexible joints let the torque shafts have small angular changes of
alignment as they turn.
The plunging joint has a universal joint which moves on splines inside a
short drive shaft. The plunging joint gives a flexible joint:
- on the output side of the flap 1 actuator
- on the input side of the line gearbox.

Each torque shaft assembly has at least one movable end connection. The movable end connection has an indicator groove. This goes out of view when the splines at the connection are correctly engaged.
Steady bearings, which hold the torque shafts, are attached to the structure with bolts. Two types of steady bearing are installed:
-
a self-aligning ball bearing only
-
a self-aligning ball bearing and univeral joint assembly.

The offset gearbox casing contains:
-a through shaft
-the torque limiter
-reduction gearing
-the rotary actuator.
The power goes from the through shaft through the torque limiter to spur gears. The spur gears move the input shaft of the rotary actuator.
R **ON A/C 062-099, 106-149, 151-199, 204-299, 401-499,
The offset gearbox has:
-an actuator housing
-
a gear cover
-
a bevel housing
-
a torque limiter.
The actuator housing is a machined casting which contains the rotary actuator and the torque limiter. The gear cover is bolted to the actuator housing and seals the input side of the actuator.
The bevel housing is bolted to the gear cover and contains an input bevel gear. This engages with a bevel gear shaft that passes through the torque limiter to transmit the output drive to the flap drive system. An input gear is installed on the bevel gear shaft. The input gear engages with an idler gear installed between the input gear and a gear wheel assembly. This gear wheel assembly engages with, and transmits the drive to, the input gear of the rotary actuator.
