Product Description
There are many kinds of gear transmission, among which the efficiency of helical cylindrical gear is very high, such as the transmission efficiency of straight cylindrical gear is lower than that of helical cylindrical gear. Helical gear like spur gear mechanism, helical gear can be used to reduce the center distance a in order to improve the bearing capacity of the transmission can be used for high-speed operation.
Mainly produces helical gears made of steel and brass, with modules from 1 to 50 and accuracy classes 6 to 9.

Advantages
01
Good Mechanical Properties
Advanced Quenching and tempering (QT) treatment makes the gears a good Mechanical properties so that it can adapt to various bad working environments.
02
High strength and good wear resistance
Gear surfaces can be carburized or nitrided to increase the hardness of the gears, increase wear resistance and extend service life.
03
Technical Support
Support customized drawing, sample processing, and can provide technical support and drawing design for installation guide and routine maintenance.
04
Quality control
Control of internal and surface defects in gears by UT, PT, and MT inspection.
