A method for measuring axial parallelism of gear pair in gearbox

Gear transmission is a device that transmits motion and power by gear pair. It is the most widely used mechanical transmission mode in modern equipment. It has the advantages of accurate transmission, high efficiency, compact structure and long service life. It is widely used in most electric tool products.

When the electric tools are working, the internal gears produce vibration and noise. When the tooth surface appears eccentric load or abnormal contact (eccentric wear), the vibration and noise are more obvious. At this time, the gear oil lubrication environment is not good, and the heat accumulation is generated at the tooth meshing of eccentric wear overload, which will damage the oil film on the tooth surface, resulting in the accelerated wear of the gear, and in serious cases, the phenomenon of “shaving” can occur.

With the development of chain saw market, more and more attention has been paid to the safety of products. According to the latest international standard ISO 13772:2018, learn and master the performance and testing methods of non manual saw chain brake, and put forward relevant suggestions combined with their own experience in chain saw design and testing, so as to provide reference for industry colleagues.
