friction gear

Instead he continued experimentation and devised the friction gearing disk drive transmission.

One of the main features of the Lambert automobile was the friction gearing disk drive transmission.

The lever which threw the former friction gear into adjustment was made to operate an idler pulley for tightening the axle-belt.

Variable-speed friction gearing.

"Everything worked to a charm, until, in starting up at one end of the road, the friction gearing was brought into action too suddenly and it was wrecked.

Some years later, also, Daft again tried friction gear in his historical experiments on the Manhattan Elevated road, but the results were attended with no greater success.

The Lambert friction gearing disk drive transmission was invented by John William Lambert originally in 1904.

However, many experienced cyclists still prefer friction gears for their simplicity and long-term reliability, as well as the ability to mix and match components from different manufacturers without the compatibility issues of indexing systems.

There is also a 16 tooth clutch gear, and a 24 tooth friction gear that slips when a certain amount of torque is put on it to prevent motors from damaging any parts or burning themselves out.

Things went fairly well for a time on that memorable Thursday afternoon, when all the laboratory force made high holiday and scrambled for foothold on the locomotive for a trip; but the friction gearing was not equal to the sudden strain put upon it during one run and went to pieces.
