Slipper gear?

[aflosi]

What is the difference between a slipper gear and a spur gear?

[Maxxcrazy]

Theres so such thing as a slipper gear and theres a such thing as a spur gear, thats the difference

Sorry, couldn't resist. The spur gear is the gear that the pinion gear drives. The pinion is mounted to the motor. The slipper is sort of like a clutch system that allows the spur gear to slip under heavy load to protect it.

A spur gear is a direct drive gear. The gear that is first in line to get the power from the engine or motor. The pinion spings the ring gear. Those are the two gears in the differentials. Hense a ring and pinion set. Spur gear is mainly for >49 tooth count and ring is for <38 tooth count. From all the documention that I have read.

Spur gear is kinda wierd though. Cause normal theory says that the power "engine or motor" and then the flywheel then the clutch then the transmission and then the differentials then the wheels. So a spur gear is a gear that has a straight cut teeth vs a 90 degee tooth cut like a ring gear.

It's called a spur because of the tooth orientation. Remember the cowboys with the things on their boots to dig into the horses. those little stars on there boots were called spurs. And that is why these gears are called spur gears. because it's an orientatial thing.

Just my Opinion.

There is a common ratio on spur gears to.
It is usually (yes i said usually cause it sometimes differs) that the engine has to turn 2-3.5 times to spin the spur gear once.
If you go to the RC calculator..you can find out the ratio of your spur gear/clutch bell

I kow you were asking for the difference between gears.thought id let you know bout ratios.
