Product Description

A large diameter ring gear is a mechanical component that is used in various types of machinery, such as heavy-duty industrial equipment, mining machinery, and construction equipment. It is typically a circular gear with teeth on its outer edge that meshes with a pinion gear to transmit torque and power between rotating components.

The size of a large diameter ring gear can vary depending on the application, but it is generally characterized by its diameter, which can range from several inches to several meters. The gear is often made of high-strength materials, such as steel, and undergoes specialized heat treatment processes to enhance its strength and durability.

Large diameter ring gears are commonly used in applications that require heavy loads and high torque, such as in mining trucks, cement mills, and large excavators. They are designed to withstand extreme operating conditions and are often subject to regular inspection and maintenance to ensure their continued reliability and performance.

thrust roller3 - Large Diameter Ring Gear

Large diameter ring gears are used to drive large, rotating systems such as dryers, rotary kilns or horizontal mills.

Large diameter ring gears are an essential component of rotary kiln and ball mill, and their material plays a crucial role in the overall performance of the equipment.

The large diameter ring gear is the central component of the rotary kiln and ball mill, and it must drive the entire cylinder for an extended period of time. As a result, firms have very high quality requirements for big ring gears in real production.

We can produce large forging,casting and welding large diameter ring gear according to customer’s drawings. According to the working conditions and clients’ request, we also can do gear grinding, surface hardening,cemented and quenching, Nitriding and quenching,etc.

Our casting large diameter ring gear is mainly used for large cement plant equipment. Such as Rotary kiln,Ball Mill,Dryer,etc.Also we can produce other big forging or casting gear ring for steel plant, Dragline excavator.It can be a whole ring gear or segment gear wheel in half,four segments.eight segments.
