In the world of mechanical power transmission, gear drives employ a special and gear chain china prominent place. This 
is the many preferred technology if you want to transmit considerable power over a short distance with a continuous velocity ratio. The system of equipment drives is very simple – one’s teeth, which are cut on the blanks of the gear wheel, mesh with each other to transmit power. In order to avoid slipping, the projections using one disc mesh with the recesses on various other disc in equipment 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 nonparallel, co-planar, and intersecting etc. shafts.
