In the world of mechanical power transmission, gear drives employ a special and prominent place. This is the many preferred technology when you need to transmit gear chain china substantial power over a brief distance with a continuous velocity ratio. The system of gear drives is very simple – the teeth, which are cut on the blanks of the gear wheel, mesh with each other to transmit power. To avoid slipping, 
the projections using one disc mesh with the recesses on other disc in equipment drives.
This technology uses different types 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.
