In the world of mechanical power transmission, gear drives employ a special and prominent place. This is gear chain china actually the most preferred technology when you 
need to transmit considerable power over a short distance with a constant velocity ratio. The mechanism of gear drives is very 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 on one disc mesh with the recesses on other disc in gear drives.
This technology uses various kinds of gears for power transmission. In fact, it could transmit power not merely between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
