1-9. MECHANICAL ANALYSIS

The RL-207(*)/G includes two reel axles and their associated clutch and brake mechanisms. The

clutch and brake mechanisms provide variable-speed drive and braking action for the reel axles.

Power for the reel axles is provided by the gasoline engine and is transmitted by a timing belt through

a jackshaft assembly to the clutch and brake assemblies. A handcrank may be used for manual

operation of either of the reel axles.

1-10. POWER DISTRIBUTION

Mechanical power for the RL-207(*)/G is supplied by

a governor-controlled gasoline engine. A timing belt

transmits power form the 14-tooth timing pulley on

the engine to the 96-tooth timing pulley on the jack-

shaft assembly. The double V-belt pulley on the jack-

shaft applies power to the V-belts that drive the two

reel axle pulleys. The speed of the reel axle pulleys

can be varied from 0 to approximately 143 revolu-

tions per minute (rpm) by controlling the slippage of

the V-belts. Belt slippage is controlled by varing the

belt tension through control of the pressure applied.

by the idler bearings.

`The payout speed will be determined by the speed at which the vehicle can be safely operated.
