New 12/24 Flat Gear Friction Measurement
TechnicBrickPower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The Lego Technic set 42140 App-Controlled Transformation Vehicle introduces two new gears - a flat version of the 12 tooth bevel gear and a flat version of the 20 tooth bevel gear. These gears are designed to have less friction. In this video I measure the difference in gearing efficiency between two gearboxes - one made from a stack of 3 of the original 12 and 20 tooth gears to create a 27 to 125 gearing ratio, and a similar version made from the new flat 12 and 20 tooth gears. The gear box losses are measured using a powered up motor and a powered up App to determined the efficiency of each gear box by lifting different weights. The results are presented and compared for each gearbox. -
Gear Friction Comparison - what's the best?
TechnicBrickPower posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
The relative friction of four different solutions for transferring motion from one axle to a far away axle are compared. The friction load differences are compared using a differential to measure the speed difference of the load on two medium motors. The four motion transfer solutions that are compared are a series of nine 16 teeth gears, three 40 teeth gears, a chain, and bevel gears driving a perpendicular axle.
