 This is a 76 tooth, 48 Pitch, spur gear from Kimbrough Products.
Kimbrough Racing Products Plastic Gears have been used to set all of the
unlimited speed records for R/C 1/10 scale electric cars in the U.S.,
and are used by a majority of the top professional R/C car racers around
the world. The best drivers in the world trust Kimbrough gears, so you
know you can too!
Kimbrough spur gears are molded with black 4/6 Nylon plastic,
because black dissipates heat into the air better then any other color -
and high temperatures are not good for thermo-setting plastics. This
plastic is almost three times tougher and will withstand operating
temperatures 75° to 125° higher than plastics used by other R/C car gear
manufacturers.
Kimbrough spur gears are full width, because a
narrow or profiled plastic gear can deform under load, is weaker and
less efficient. This can cause drag in the gear train and waste
horsepower. The wider a gear is, the more load it can handle. The only
time gear engineers narrow gears, is when there is a space limitation.
Kimbrough Racing Products gears run quiet because they have the correct
tooth shape and don't have to be narrowed.
NOTE: The use of full width pinion gears is highly recommended. |
