In the wonderful world of mechanical power gear chain china transmission, gear drives employ a special and prominent place. This is the most preferred technology when you need to transmit considerable power over a short distance with a constant velocity ratio. The system 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. To avoid slipping, the projections on one disc mesh with the recesses on other disc in equipment drives.
This technology uses different types of gears 
for power transmission. Actually, it could transmit power not only between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
