Precision gear are often seen in life. Someone may ask this question:how does precision gears work? What are the system principles and classifications of precision gear transmission?

Precision gear transmission is realized by the driving gear moving the driven wheel and one of its basic requirements is to keep instantaneous angular speed ratio unchanged. The main characteristics of gear transmission are:wide peripheral speed and power range;Accurate,stable and efficient transmission ratio;high working reliability and long service life;parallel shaft,arbitrary angle cross shaft and arbitrary angle cross shaft drive;high manufacturing and installation accuracy and high cost;Not suitable for transmission two shafts.

Classifications of precision gear transmission :gear transmission is used in transmit motion and power between any two shafts in space.The relative motion of two gears can be regarded as plane motion or space motion.It can be divided into plane gear transmission and space gear transmission.

1.Plane gear transmission mode:plane gear transmission is used for transmission between two parallel shafts.There are three common types:straights cylindrical gear transmission,helical cylindrical gear transmission and herringbone gear transmission. According to the tooth direction,plane gear transmission can also be divided into external meshing,internal meshing and gear rack meshing.

2.Space gear transmission type:space gear transmission is mainly used for two cross shafts or two cross shafts transmission,common bevel gear transmission type.cross shaft helical gear transmission, etc.

The above is an introduction to the types of precision gear transmission. If you need precision gear, please consult IHF Hefa gear manufacturer
