In the wonderful world of mechanical power transmission, gear drives employ a special and prominent place. This is actually the the majority of preferred technology when you need to transmit considerable power over a brief distance with a constant velocity ratio. The mechanism of equipment drives is quite simple – one’s teeth, which are cut on the blanks of the apparatus wheel, mesh with one another to transmit power. In order to avoid slipping, the projections using one disc mesh with the recesses on other disc in equipment drives.
This technology uses various kinds of gears for power transmission. Actually, it can transmit power not merely gear chain china between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
