Embodiment

[0016] During the maintenance operation of the large ring gear of the rotary kiln, the specific operation steps are as follows:

[0017] 1. Set the rotary kiln tool.

[0018] 2. Measure the original radial runout of the large ring gear and the lower barrel section of the large ring gear.

[0019] 3. Stop the large ring gear in a horizontal position, remove the large ring gear counterpart bolts, and locate the pin bolts.

[0020] 4. Cut off the spring ear plate and remove the upper half ring gear.

[0021] 5. Rotate the kiln body, turn the lower half of the ring gear to the upper side, cut off the spring ear plate, and remove the lower half of the ring gear.

[0022] 6. Clean up the residual welding meat and iron oxide on the spring plate. After processing, each spring plate should be tested with the processed lug plate.

[0023] 7. Clean and align the large ring gear.

[0024] 8. Install the large ring gear

[0025] 8.1 When hoisting the ring gear, it should be lowered f...

Abstract

The invention discloses a rotary kiln heavy gear ring repairing method, and relates to a rotary kiln repairing method which is used in metallurgy, building materials and chemical industries. The method is characterized in that a repairing operation process comprises the following steps that: (1) a spring board and heavy gear ring connecting lug is cut off, and a heavy gear ring is removed; (2) the heavy gear ring is cleaned and set the heavy gear ring round; (3) the turned over heavy gear ring is hoisted and aligned; and (4) a pin shaft is installed, and a spring board and a new lug are welded. The rotary kiln heavy gear ring repairing method turns over and repairs the heavy gear ring under the circumstance of not replacing a tube section and the spring board, first cuts the spring board and heavy gear ring connecting lug, keeps a tube body and the original spring board unchanged, removes the gear ring and turns over the same and then replaces the new lug and the pin shaft; and after the heavy gear ring is aligned, the new lug and the original spring board are welded firmly. The rotary kiln heavy gear ring repairing method effectively saves the cost for the tube section, the spring board, a rivet and other spare parts, omits spring board installation, hole drilling, riveting and other procedures, and saves a certain repairing time.

Description

technical field [0001] The invention relates to a method for repairing a large ring gear of a rotary kiln, relating to a method for repairing a rotary kiln used in metallurgy, building materials and chemical industries. Background technique [0002] Rotary kiln is widely used in metallurgy, building materials, chemical industry and other industries. The large ring gear is one of the most critical components in the transmission device of the rotary kiln. It is connected by two half gears with matching screws and fixed tangentially on the kiln body by a spring plate. . The large ring gear has been in operation for a long time, and the ring gear is seriously worn. When the rotary kiln is overhauled, it is usually replaced or turned over for repair. In order to save the cost of spare parts, it is usually turned over before use. [0003] At present, if the large ring gear is turned over or replaced and repaired, its lower barrel section and spring plate need to be replaced and r...
