In the wonderful world of mechanical power transmission, gear gear chain china drives employ a special and prominent place. This is actually the many preferred technology if you want to transmit significant power over a brief distance with a continuous velocity ratio. The mechanism of gear drives is very simple – one’s 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 gear 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.
