What are the advantages of gear drives?
The advantages of gear transmission: compared with other forms of transmission, it has a large range of transmission power, wide speed adaptability, small size, high efficiency, long life and low bearing capacity of the axle.
4) the speed range is large; the circumferential speed of gear can reach 200m/s or higher from V<0.1M/S; the speed can range from n<1 r/min to 20000r/min;5) transmit power range, high carrying capacity;6) the transmission efficiency is high, especially of cylindrical gears with high accuracy, the efficiency can reach above =0.99;7) compact structure, such as the use of planetary transmission, small teeth difference drive, or harmonic gear drive, can make the components more reduced, become coaxial drive;8) easy maintenance.
Advantages of gear drive:1) the instantaneous transmission ratio is constant, and the work stability is higher;2) non circular gear, the instantaneous transmission ratio according to the required design changes;3) change gear ratio range, especially using planetary transmission, the transmission ratio can be up to 100~200 (single stage), the growth rate for slow down or drive;
The advantages of gear transmission </A> transmission gear, the use of two gear teeth meshing, transfer power and motion of the mechanical transmission, with the main, driven wheel gear directly, and transfer movement and power device. According to the relative position of the gear axis, it is divided into parallel shaft cylindrical gear drive, intersecting shaft cone gear drive and staggered shaft helical gear drive. The utility model has the advantages of stable transmission, accurate drive ratio, reliable work, high efficiency, long service life, large power, speed and large size range.
