In the world of 
mechanical power gear chain china transmission, gear drives have a very special and prominent place. This is the the majority of preferred technology if you want to transmit considerable power over a short distance with a continuous velocity ratio. The mechanism of gear drives is very simple – one’s teeth, which are cut on the blanks of the gear 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. In fact, it could transmit power not merely between parallel shafts, but also between non-parallel, co-planar, and intersecting etc. shafts.
