In the world of mechanical power transmission, gear drives employ a special and gear chain china prominent place. This is the most preferred technology if you want to transmit considerable power over a short distance with a continuous velocity ratio. The mechanism of equipment drives is very simple – the teeth, which are cut on the blanks of the apparatus wheel, mesh with each other to transmit power. In order to avoid slipping, the projections on one disc mesh with the recesses on various other disc in equipment drives.
This technology uses different types of gears for power transmission. Actually, it can transmit power not merely between parallel shafts, but also 
between nonparallel, co-planar, and intersecting etc. shafts.
