In the world of mechanical power transmission, gear drives have a very special and prominent place. This is actually the many preferred technology if you want to transmit significant power over a brief distance with a constant velocity ratio. The mechanism of gear drives is very simple – the teeth, which are cut on the blanks of the apparatus wheel, mesh with one another to transmit power. In order to avoid slipping, the projections on one disc mesh with the recesses on other disc in gear drives.

This technology uses various kinds of gears for power transmission. Actually, it can transmit power not only between parallel shafts, but also between gear chain china non-parallel, co-planar, and intersecting etc. shafts.
