Girth gear is the key component to support the transmission system stability of rotary kiln and ball mill, which are often forged or cast structure high quality and strength alloy steel with surface carburizing or hardening treatment. Girth gears have the high bearing capacity and durable. In practical application, which is widely used in high speed and heavy load machinery, because of its stable transmission, low impact, vibration and noise. Our company can produce different type gear ring and wheel such as spur gear, helical gear, herringbone gear wheel and gear ring according to the customer's drawing and requirements.
