Product Description

Product Description

Big gear ring is one of the commonly used mechanical parts, Large gear rings have different roles in different mechanical equipment, but in general, its core function is mainly to transfer power and support the cylinder or structure of the equipment.
Big tooth ring is one of the key parts of rotary kiln equipment. It transmits power by meshing with the pinion to drive the cylinder of the rotary kiln to rotate. The large tooth ring carries the weight of the whole rotary kiln, and its stability has an important influence on production efficiency and product quality.
The big tooth ring is also one of the main components of the ball mill. Through the torque transfer between the pinion and the big gear, the rotary movement of the mill cylinder is realized, so as to grind the material.
