ring gear

1.Bevel gears are used to transmit motion and power between two intersecting axes. In general machinery, the intersection angle between the two axes of bevel gears is equal to 90° (but it may not be equal to 90°). Similar to cylindrical gears, bevel gears have indexing cones, tip cones, root cones and base cones. The cone has a big end and a small end, and the circles corresponding to the big end are called the graduation circle (its radius is r), the tooth tip circle, the tooth root circle and the base circle. The movement of a pair of bevel gears is equivalent to pure rolling of a pair of pitch cones. 2.Our company has many years of manufacturing and production experience, complete equipment, and a professional technical team. We have cooperated with many new and old customers at home and abroad for many times. We can design and produce according to the required drawings provided by customers to meet customer needs. We also have a pair of First-class service, please believe us. If you have needs, you can find out first. Customers are welcome to consult.

1.Segmented large ring gears are used to drive large rotating systems, such as dryers, rotary kilns, and horizontal mills 2.Advantages (1) Minimum vibration: The segmented large ring gear has high-precision pitch. （2）Easy to replace because the large ring gear is divided into multiple segments without having to disassemble the entire ring gear. （3）The longer service life is due to the use of appropriate size and reasonable lubrication, so that the large ring gear made of material has no wear in actual use.

1.Herringbone gears combine the advantages of helical gears (high load capacity) and spur gears (no axial force). 2.Herringbone gears can transmit high torque due to their relatively long tooth length (due to the inclination). However, the complex and therefore expensive production of this gear type is limited to special applications. (e.g. for large transfers)

Large ring gear is fully tempered and quenched , so that it has good comprehensive mechanical properties, and has good plasticity and toughness while ensuring high strength. To provide customers with ring gear castings with high service life and high operating rate.

1.The large ring gear is one of the important components of rotary kiln, ball mill, dryer and other machinery, so the quality of the ring gear is related to the stability and service life of the ball mill and rotary kiln. 2.The large ring gear is a very critical component in the transmission device of ball mills and rotary kilns. It drives the entire cylinder to rotate at low speed for a long time. Its quality directly affects the smoothness of the transmission system of ball mills and rotary kilns, the stability of operation, and the quality of the lining. The service life and the operation rate of the kiln and the grinding mill, so the quality requirements of the large ring gear in actual production are very high.

Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably.

1. The work is simple and sensitive, and the rotation resistance is small. 2. The structure is compact and the dimensions (mainly height) are small. 3. Convenient maintenance and long service life. 4. It is composed of ring gear, seal and screws, etc. It is easy to install and convenient for specialized centralized production. 5. There is no intermediate pivot, and other components can be installed in the middle space.

1)Selecting high-quality raw materials and strictly controlling the production process; 2) Using LF refining furnace and VD vacuum degassing furnace to ensure the internal quality of ring gear castings; 3) During the casting process, CAE simulation pouring software is used to assist the design process, so as to modify the pouring model in time , so as to better control the quality of the ring gear blank; 4) Large ring gear is fully tempered and quenched , so that it has good comprehensive mechanical properties, and has good plasticity and toughness while ensuring high strength. To provide customers with ring gear castings with high service life and high operating rate.
