Classification and characteristics of gear transmission

According to the relative positional relationship between a pair of gear shafts and shafts, it can be divided into parallel shaft gear transmission, intersecting shaft tooth transmission and staggered shaft gear transmission.

1.平行轴齿轮传动可分为圆柱齿轮传动,非圆齿轮传动 按齿廓形状分为 1.浙开线齿轮传动 2.圆弧齿轮传动 3.摆线齿轮传动 4.其他

2. Intersecting shaft gear transmission (according to the shape of the tooth line) 1. Straight bevel gear transmission 2. Helical bevel gear transmission

Curved bevel gear transmission 1. Spiral bevel gear transmission Cycloidal bevel gear transmission Equal base bevel gear transmission

3. Staggered shaft gear transmission Staggered shaft helical gear transmission

Hypoid gear transmission can be divided into arc tooth hypoid gear transmission and cycloid hypoid gear transmission

Worm drive can be divided into cylindrical worm drive, toroidal worm drive and conical worm drive

Cylindrical worm drive 1. Archimedes cylindrical worm drive (ZA) 2. Arc cylindrical worm drive (ZC) 3. Zhejiang open line cylindrical worm drive (ZI) 4. Normal straight profile cylindrical worm drive (ZN)

The toroidal worm drive can be divided into 1. Straight profile toroidal worm drive (TA) 2. Flat tooth enveloping toroidal worm drive (TI) 3. Zhejiang open enveloping toroidal worm drive (TI) 4. Conical surface Torus worm drive (TK)

According to the relative motion relationship between the central axis of the gear train and the front of the shaft, it can be divided into a fixed-axis gear train and an epicyclic gear train.In the epicyclic gear train, one driving member forms a definite movement called a planetary gear train, and two driving members form a definite movement called a differential train.In planetary gear transmission, there are mainly;

1. Zhejiang open line planetary gear transmission 2. Less tooth difference planetary gear transmission

Small tooth difference planetary gear transmission can be divided into 1. Zhejiang open line gear small tooth difference planetary transmission 2. Cycloidal pin gear planetary reducer 3. Harmonic gear transmission
