In the world of mechanical power transmission, gear drives employ a special and prominent place. This is actually the many preferred technology if you want to transmit considerable power over a brief distance with a gear chain china constant velocity ratio. The system of gear drives is fairly simple – one’s teeth, which are cut on 
the blanks of the gear wheel, mesh with each other to transmit power. To avoid slipping, the projections using one disc mesh with the recesses on various other disc in equipment drives.
This technology uses various kinds of gears for power transmission. Actually, it can transmit power not only between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
