Analyze the installation method of rotary kiln ring gear

16 Mar,2018 UTC+8 Views:


Rotary kiln ring gears are usually made into two halves or several pieces because of their large size. They are connected together by bolts. The center line of the big ring gear must coincide with the center line of the cylinder. The ring gear is generally installed in the middle of the kiln body so that the cylinder is subjected to uniform force during operation, and it is also far away from the hot end with less dust.

There are usually two ways to install the rotary kiln ring gear. let's see it together:

1. The tangential connection ring gear is fixed on the spring steel plate in the tangential direction of the cylinder body. Generally, a 20-30mm thick steel plate is used. One end is riveted on the cylinder body to make it tangent to the cylinder body, and the other end is screwed or pinned. Ring gear flange connection. This connection method has greater flexibility, and can reduce the impact on the large and small gears caused by the bending or opening or stopping of the cylinder. The disadvantages are that the installation is difficult, the center is not easy to identify, and gear manufacturing is difficult.

2. Axial connection is to fix the ring gear on the elastic steel plate parallel to the barrel, and put 2 ring plate seats on the barrel, the distance between them is 1.4-1.8m, there are 8-15 elastic steel plates in the middle , With the backing plate riveted to the cylinder, the ring gear is fixed on the steel plate. The pinion gear is usually mounted diagonally below the ring gear and the centerline of the pinion and pinion should be parallel.

The above is the two installation methods of the rotary kiln ring gear and the pinion gear. In this link, we must pay attention to the appropriate and timely processing methods, so that we can get better results in the subsequent use, and also facilitate the maintenance and maintenance of the later period. . Therefore, when installing the large ring gear, we must pay attention to the stability and safety when handling the large ring gear in accordance with the specifications, so as to ensure the use of the later period and the maintenance of the steel castings.
