Feature 1: High transmission accuracy. The transmission ratio of commonly used involute gears is accurate and constant. This is not only a key requirement for precision machinery and instruments, but also an important condition for reducing dynamic loads under high speed and heavy loads to achieve smooth transmission;

Feature 2: Wide application range. The power range transmitted by gear transmission is extremely wide, ranging from 0.001W to 60000kW; the peripheral speed can be very low or as high as 150m/s, which is difficult to match with belt transmission and chain transmission;

Feature 3: It can realize the transmission between any two axes in space, such as parallel axes, intersecting axes, staggered axes, etc., which is also impossible for belt drive and chain drive;

Feature 4: Long service life and high transmission efficiency;

Feature 5: High transmission efficiency;

Feature 6: It has strict requirements on environmental conditions. Except for a few low-speed and low-precision situations, it generally needs to be placed in a box cover to prevent dust and scale, and lubrication is also required.
