According to the relative positional relationship between a pair of gear shafts and shafts, it can be divided into parallel shaft gearing - intersecting shaft gearing and staggered shaft gearing.
1. Parallel shaft gearing can be divided into cylindrical gearing, non-circular gearing gears According to the shape of the tooth profile is divided into 1. Zhejian gearing 2. Arc gearing 3.
2. Intersecting shaft gearing (according to the shape of the tooth line) 1. straight bevel gearing 2. helical bevel gearing
Curved tooth bevel gearing 1. Arc tooth bevel gearing Pendulum tooth bevel gearing Equal base bevel gearing
3. Staggered shaft gearing Staggered shaft helical gearing
Hypoid gearing can be divided into arc tooth hypoid gearing and cycloid tooth hypoid gearing.
Worm gearing can be divided into cylindrical worm gearing and ring face worm gearing and cone face worm gearing.
Cylindrical Worm Drive 1.Archimedean Cylindrical Worm Drive (ZA) 2.Circular Arc Cylindrical Worm Drive (ZC) 3.Zhekai Line Cylindrical Worm Drive (ZI) 4.Normal Face Straight Profile Cylindrical Worm Drive (ZN)
Annular worm gearing can be divided into 1. straight profile annular worm gearing (TA) 2. plane tooth envelope annular worm gearing (TI) 3. Zhekai envelope annular worm gearing (TI) 4. taper envelope annular worm gearing (TK)
According to the relative motion relationship between the shaft and the shaft before the wheel system can be divided into fixed-axis wheel system and turnover wheel system. In the swing wheel system, one active member to form a definite motion is called the planetary wheel system, and two active members to form a definite motion is called the differential system. In planetary gearing there are mainly;
1. Zhekelen planetary gearing 2. Differential planetary gearing
Differential planetary gearing can be categorized into 1. Zhe Zhe gear differential planetary gearing 2. Cycloid planetary gearbox 3. Harmonic gearing
