Bevel gears are used to transmit power between

shafts in the same axis

Worm drives operated in shafts which are

non-parallel and non intersecting.

On a chain assembly , a change in direction of straight line motion in two planes is achieved by

using bi-planer blocks.

When not under load a pair of gears

sit in the middle.

is a type of gear would be used on propeller reduction gearbox

Epicycle

The larger diameter on a bevel gear is called the

heel

Non-reversible chains are similar to standard chains except that each outer plate is extended in

one direction in order to break up the symmetry of the chain to prevent the chain from being assembled incorrectly .

are the most common and cheapest type of gears.

Spur gears

The teeth of a gear would normally be

case hardened

are necessary in a main rotor gearbox of helicopter.

Conformal gears

If both the drive gear and driven gear have the identical number of teeth

no mechanical advantage is gained.

The main reason for a slipping belt of pulley is

too much pre-tensioning

are the transmission forms that are typically used on aircraft

Belt and pulley drives, Screw jacks and Chains

are toothed wheels used to transmit power between components of a machine where the centre distances between the shafts is limited.

Chains

When two gears are running together the larger one is called a

gear .

When two gears are running together the smaller one is called a

pinion

the purpose of bell cranks is

to make angle changes between push-pull rods and to gain mechanical advantages.
