Item 1319

DESIGN: SynchroLite ~ Power Train (for 1 engine) - Assembly - Layout - 3 Gear Sets (11)

Notes:

The overrunning clutch is inside the primary reduction crown gear.

Could put a type of gear set between the two masts just above the proper gears, to assure that the gears will always intermesh. Better yet, just use stronger gears.

The optional 3-cylinder engine is about 5" longer than the 2-cylinder.

The engines could be angled up or down, if required.

Considerations:

Make primary set 3:1.

Make secondary set 2.77:1.

Put overrunning clutch in primary pinion shaft. NO. Put it between the primary crown gear and the X-shaft, thereby leaving only 4 gears in the portion of the power-train with the enhanced safety factor.

Bring secondary gears closer together and move lower, due to small crown gear and less space between them.

May not have to make special allowance for expansion between secondary pinions.

65 hp (60hp) de-rated to 50 hp.

100% RRPM = 5500 engine rpm

Primary Reduction and Soft Start: This must be revised

Overrunning Clutch:

The overrunning clutch is to be located between the large pulley and the input shaft to the gearbox. The torque is 132 ft-lb and the shock loading, even though it is downstream from the belts, will be high. Power Train Access Form

	Consider 2 Warner CSK 35 (Item 0568), Max. torque 207 ft-lb. Sprag. C/w brgs, 0.66 lbs.
	Consider Warner CSK 40, (Item 0741) Max. torque 384 ft-lb. Sprag. C/w brgs?, 1.10 lbs. This weighs more but it means less material in adjoining items.
	Consider 2 Marland-RINGSPANN R206 (Item 0524), Max. torque 195 ft-lb. No brgs. Keyway
	Consider Marland-RINGSPANN R208 (Item 0141), Max. torque 450 ft-lb. No brgs. Keyway

Housing:

An upper casting will contain the bearings for the mast and the attachment lug to the fuselage. The lower portion may consist of two halves, which might be identical except LH & RH, The left hand one has a plug where the input shaft is on the right hand one and this allows for a future PTO. ???

Lubrication:

Splash. How.
