Gear mechanical transmission is the most widely used as a form of transmission. It's more accurate transmission, high efficiency, compact structure, reliable operation and long life.

Feature
1, the instantaneous transmission ratio constant. Instantaneous transmission of non-circular gear ratio can change according to the law need to design.
2, the transmission ratio range, or it can be used to slow down the growth rate.
3, range rate (knuckles round peripheral speed) and transmission power is large, can be used for high speed (v> 40m / s), medium-speed and low-speed (v <25m / s) of transmission; power from less than 1W to 105KW.
4, high transmission efficiency. One pair of high-precision involute cylindrical gears, efficiency up to 99%.
5, compact structure, is suitable for short distance transmission.
6, higher manufacturing costs. Some high gear with a special tooth or precision, or because of the need of a dedicated high-precision machine tools, cutting tools and measuring instruments, etc., so the manufacturing process is complicated and costly.
7, high precision gears, noise transmission time, vibration and impact of large, polluting the environment.
8, no role overload
