In the wonderful world of mechanical power transmission, gear drives have a very special and prominent place. This is the the majority of preferred technology if you want to transmit significant power over a short distance with a constant velocity ratio. The system of equipment drives is fairly simple – the teeth, which are cut on the gear chain china blanks of the apparatus wheel, mesh with one another to transmit power. To avoid slipping, the projections using one disc mesh with the recesses on additional disc in gear drives.
This technology uses various kinds of gears for power transmission. In fact, it can transmit power 
not only between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
