The gear drive needs two gears to operate. The two gear drivers are spur gears, and the drive gear receives force from the power output end. The driving gear transmits the power to the driven gear, and the gear transmission device relies on two or more meshing gears to transmit the power. The gear transmission ratio is accurate and suitable for high manufacturing accuracy and installation accuracy.
The gear transmission system has the following 8 advantages:
1. Constant instantaneous transmission ratio and high working stability;
2. Using non-circular gears, the instantaneous transmission ratio can be designed according to the required change rules;
3. Easy maintenance and uniform load distribution;
4. The gear transmission ratio has a wide range of changes and is suitable for decelerating or accelerating transmission. Especially when planetary transmission is adopted, the transmission ratio can be large;
5. The circumferential speed and speed of the gear can be very large;
6. Large transmission power and high bearing capacity;
7. High transmission efficiency, especially suitable for high-precision cylindrical gear pair;
8. Compact structure, such as planetary transmission, small tooth difference transmission, or harmonic gear transmission, can further reduce components and become coaxial transmission. Planetary transmission is applicable to high-precision transmission. The diameter range of the planetary gearbox we make is 3.4mm-38mm.
At the same time, the gear transmission system has the following three deficiencies:
1. High requirements for manufacturing and installation accuracy;
2. The manufacturing process is complex and expensive;
3. Not suitable for long-distance transmission between two axes.
