In the world of mechanical power transmission, gear drives have a very special and prominent place. This is actually the most preferred technology if you want to transmit considerable power over a short distance with a constant velocity ratio. The system of gear drives is pretty simple – the 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 gear drives.
This technology uses gear chain china various kinds 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.
