In the world of mechanical power gear chain china transmission, gear drives employ a special and prominent place. This is the many preferred technology if you want to transmit substantial power over a short distance with a continuous velocity ratio. The mechanism of gear drives is fairly 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 various kinds of gears for power transmission. Actually, it could transmit power not only between parallel shafts, but also between nonparallel, co-planar, and intersecting etc. shafts.
