A gear drive requires two gears for operation. The two gear drives are spur cut, and the drive gear receives force from the power output. The drive gear then transfers power to the driven gear. The gear drive relies on two or more intermeshing gears to transmit power. The gear transmission ratio is accurate, which is suitable for high manufacturing precision and installation accuracy. The gear drive system has the following features.
The advantages of the gear drive system:
1. The instantaneous transmission ratio is constant, and the work stability is high;
2.Using non-circular gears, the instantaneous transmission ratio can be designed according to the required change rule;
3.Easy maintenance and uniform load distribution.
4.The gear ratio has a wide range of variation, which is suitable for deceleration or speed increase transmission. Especially when adopting planetary drive, the gear ratio can be made very large;
5.The peripheral speed and speed of the gear can be made very large;
6.The transmission power is large, and the carrying capacity is high;
7.High transmission efficiency, especially for cylindrical gear pairs with high precision.
8.Compact structure, such as the use of planetary transmission, less tooth difference transmission, or harmonic gear transmission, the components can be further reduced, becoming a coaxial transmission. The planetary transmission is suitable for high precision drives. The diameter range of the planetary gearbox we made is 3.4-38mm.Easy maintenance and uniform load distribution.
The disadvantages of the gear drive system:
1. High precision in manufacturing and installation;
2. The manufacturing process is complicated and costly;
3. Not suitable for transmission between two axes at a long distance.
