In the world of mechanical power transmission, gear drives employ a special and prominent place. This is the most preferred technology when you need to gear chain china transmit significant power over a brief distance with a constant velocity ratio. The mechanism of gear drives is fairly simple – the teeth, which are cut on the blanks 
of the gear wheel, mesh with one another to transmit power. To avoid slipping, the projections on one disc mesh with the recesses on various other disc in gear drives.
This technology uses various kinds of gears for power transmission. Actually, it could transmit power not merely between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
