In the wonderful world of mechanical power transmission, gear drives employ a special and prominent place. This is the many preferred technology if you want to transmit substantial power over a short distance with a continuous velocity ratio. The mechanism of gear drives is pretty simple – the teeth, which are cut on the blanks of the gear wheel, mesh with each other to transmit power. To avoid slipping, the gear chain china projections using one disc mesh with the recesses on various other disc in gear drives.
This technology uses various kinds of gears for power transmission. Actually, it can transmit power not merely between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
