In the world of mechanical power transmission, gear gear chain china 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 equipment drives is fairly simple - one's 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 additional disc in equipment drives.

This technology uses various kinds of gears for power transmission. Actually, it could transmit power not merely between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
