Explain the meaning of variable speed ratio. (1:15, meaning that the input shaft rotates one revolution, the output shaft rotates 15 revolutions) Incremental gear box, used in reverse, can also be used as a reduction gear box Oh!

The thickness of steel plate is 6mm, the thickness of gear is 20mm. Input shaft diameter 25, output shaft diameter 15 millimeters.

This model is customized. 1:15, single steel plate length 28 cm, width 14 cm, the distance between the two steel plates 8 cm. 1:15 weight of about 10 kg.

Different gear ratios, different sizes, different prices. The weight is also different. Subject to the actual.
