The existence of precision gear products can provide good operating power for large equipment, which is indispensable for these equipment. It is quite widely used and plays an important role not only in devices but also in many children's toys. Of course, there are many types of precision gears, and the transmission effects of different types of gears will be different. Large equipment will have stricter requirements on gear transmission performance.
Gear transmission classification:
1. According to the axial transmission: it can be divided into plane gear transmission and space gear transmission. Surface gear drive: spur gear drive, helical gear drive, herringbone gear drive; space gear drive: bevel gear drive, cross helical gear drive, worm gear drive;
2. According to whether the gear is closed: open and close the gear transmission.
Advantages and disadvantages of precision gear transmission:
Compared with other transmission forms, precision gear transmission has the advantages of large transmission power, wide development range, high efficiency, long life, more compact structure, and can maintain a constant transmission ratio.
The disadvantage is that the production and precision requirements are high, the cost is high, and it is not suitable for transmission with too large center distance between the two axes.
