Girth Ring

A girth ring is one of the commonly used mechanical parts, which is to transfer and change the direction of the torque, especially in the rotary kiln, the girth ring is one of the key parts of the rotary kiln transmission, it is also widely used in other application that require high torque and low cost transimission.

1. The Girth ring is suitable for large torque operation.
2. OEM and customizable according to drawings.
3. Related transmission parts can be provided, like gearbox, motor, oil station, control system, etc.
4. Heavy Load, it can be separated into several segments, like 2 pieces, 4 pieces, and 8 pieces.

 

Girth ring, also known as ring gear, girth gear, is a mechanical part with ring gear structure. The following is a detailed introduction to the girth ring:
Structural characteristics
Tooth structure: the teeth are distributed on the circumference of a ring, and there are internal teeth and external teeth. The teeth of the inner ring are on the inside of the ring, and the teeth of the outer ring are on the outside of the ring. The tooth shape usually has involute tooth shape, cycloidal tooth shape, etc., among which the involute tooth shape is widely used, and has the advantages of smooth transmission and strong bearing capacity.
Overall shape: The whole is circular, with different diameters and width sizes to adapt to different installation space and transmission needs. Some ring rings are complete rings, and some may be spliced by multiple ring segments, such as some large ring rings, in order to facilitate manufacturing, transportation and installation, will be designed into a structure of two halves or multiple lobes, assembled together by bolts and other connectors.

Girth rings are usually used in conjunction with other gears or transmission components, such as planetary gears and solar gears to form planetary gear transmission systems. In the planetary gear system, the sun gear is located in the center, and the planet gear revolves around the sun gear and rotates while engaging the inner teeth of the ring gear ring. Power input from the sun gear, through the planetary gear to the ring gear ring, or output from the ring gear ring, to achieve power transmission, speed change, commutation, and other functions.

Industrial transmission field: In all kinds of reducer, transmission, ring gear ring is an important component, such as planetary reducer, the inner gear ring and planetary wheel coordination, to achieve a large transmission ratio, high-precision reduction transmission. In some large industrial equipment such as rolling mill, mining machinery transmission system, also often use large size ring tooth ring to transmit large torque.

Aerospace field: High-precision and lightweight ring gear rings are used in aircraft engine transmission systems and attitude adjustment mechanisms of aerospace vehicles to meet the requirements of high reliability, high transmission efficiency, and compact structure.

Automotive field: In the automatic transmission, the ring gear ring is an important part of the shifting mechanism, which achieves different transmission ratios by cooperating with planetary gears, etc., to meet the speed and torque needs of the car under different driving conditions.
