Problems solved by technology

It takes at least 6 days to install or replace the sub-items of the large ring gear, and due to the unstable operation of the rotary kiln body and the axial movement of the kiln body, it is difficult to guarantee the alignment accuracy of the large ring gear
At the same time consume a lot of manpower and material resources

Embodiment

[0026] The large gear ring of the rotary kiln usually adopts two half-ring structures, which are connected together with matching screws and fixed tangentially on the kiln body through spring plates; the specific implementation steps are as follows:

[0027] 1. Set up a square assembly platform, the side length is 2m longer than the diameter of the large gear ring.

[0028] 2. The production of the connecting cylinder section of the large ring gear must be processed by a machine tool, and its roundness must meet the requirements, and the two ends of the cylinder section are vertical. And use the processing machine tool to draw the center line and the upper and lower two circumferential lines of the spring plate installation position on the outer circle.

[0029] 3. Large ring gear assembly and calibration

[0030] 3.1 Take the center of the platform as the center of the circle, plan the outer circle of the cylinder and the inner and outer circles of the end of the large ring ...

Abstract

The invention discloses an installation method of a big gear ring of a rotary kiln, which relates to rotary kiln installation, big gear ring replacement or installation method after turn-over repair in aluminum oxide, building material, nonferrous metal and metallurgical industries. The invention is characterized in that the installation process comprises the steps of preassembling the big gear ring and a lower shell ring thereof, aligning and installing integrally after connecting the big gear ring and the lower shell ring into a whole body. In the method, a large-tonnage jack-up plate rotary kiln body mechanism does not need to be arranged, and barrel and gear ring deflection alignment is carried out directly via an auxiliary transmission system. The invention shortens construction period, increases the installation accuracy of the large ring gear, improves the working environment for constructors and relieves labor intensity.

Description

technical field [0001] A method for installing a large ring gear of a rotary kiln relates to a method for installing a rotary kiln in the industries of alumina, building materials, non-ferrous metals, and metallurgy, after replacing the large ring gear or after turning over and repairing it. Background technique [0002] The large ring gear is one of the main components of the rotary kiln. During the installation process of the rotary kiln, the installation of the large ring gear is an important link, which requires high precision and complicated processes. At present, there are mainly two methods for installing the large ring gear. One is component installation: after the rotary kiln cylinder is installed and aligned, the two halves of the gear ring are installed and aligned in place. The advantage is that the cylinder can be connected into a The disadvantage is that it is difficult to guarantee its roundness and installation accuracy after the whole is installed. The secon...
