Description
The supplementary set from the Lego Technic series includes, among others, a gearbox for the electric motors. With this gearbox, the electrical drive could be reduced. The transmission’s value is 1:20. This means that if the drive rotates 20 times on its axis before transmission, it rotates only once on its axis after transmission. The gearbox blocks were suitable for both 4,5 Volt motors (as in the supplementary set no. 870) and 12 Volt motors (as in the supplementary set no. 880).
