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 at high speeds and heavy loads and realizing smooth transmission.

Feature 2: Wide range of application. Gear transmission power transmission range is extremely wide, can be from 0.001W to 60,000kW; circumferential speed can be very low, can also be as high as 150m / s, belt drive, chain drive are difficult to compare.

Feature 3: It can realize the transmission between any two axes in the space such as parallel axes, intersecting axes, staggered axes, etc., which can not be done by belt drive or chain drive.

Feature 4: Long service life and high transmission efficiency.

Feature 5: Higher transmission efficiency.

Feature 6: Strict environmental conditions, except for a few low-speed: low-precision cases, generally need to be housed in a box cover to prevent dust and dirt, but also need to pay attention to lubrication.
