Mechanical equipment transmission modes
Mechanical transmission is divided into gear drive, turbine vortex rod drive, belt drive, chain drive and gear train.
1. Gear transmission
Gear transmission is one of the most widely used transmission forms in mechanical transmission. It has the advantages of accurate transmission, high efficiency, compact structure, reliable operation and long life. Gear transmission can be divided into many different types according to different standards.
Advantages: it has compact structure, which is suitable for wide range of circumferential speed and power. The transmission ratio is accurate, stable and efficient. The working reliability is high, the life is long, and the transmission between parallel shaft, arbitrary angle intersecting shaft and arbitrary angular staggered shaft can be realized.
Disadvantages: it needs high manufacturing and installation accuracy, high cost, which is not suitable for long distance transmission between two shafts, and has no overload protection.
2. Turbine vortex rod drive
Turbine vortex rod drive is suitable for motion and power between two shafts with vertical and disjoint space.
Advantages: it has large transmission ratio and compact structure size.
Disadvantages: it has large axial force, it is easy to heat up, with low efficiency and one-way transmission.
The main parameters of turbine vortex drive include modulus, pressure angle, worm gear dividing circle, worm dividing circle, guide, worm gear tooth number, worm head number, transmission ratio and so on.
3. A gear train
A gear train consisting of more than two gears is called a gear train. Whether there is an axis moving gear in the gear train, the gear transmission can be divided into ordinary gear drive and planet gear transmission. The gear with axis motion in the gear train is called the planet gear. The gear train is suitable for the transmission between the two shafts far away, can be used as a transmission to achieve variable transmission, and can obtain a larger transmission ratio; to achieve the synthesis and decomposition of motion.
