What is a large girth gear?
2019-09-10 | Editor:
The large girth gear is one of the commonly used mechanical parts, through which the direction of the force is transmitted and changed, especially in rotary kiln, which is one of the key components in the rotary kiln transmission. Since the large ring gear is a thin-walled ring forging, problems such as uneven wall thickness, folding, and ellipse are likely to occur during the forging process. Therefore, in the processing and production, the casting details must be strictly controlled to enhance the quality of the large girth gear components.
Due to the manufacturing capacity, transportation and installation requirements, the large girth gear is composed of two half gears, which are connected together by the counter screws and fixed to the kiln body by the tangential direction of the spring plate. It is necessary to complete the installation of the large girth gear with high quality. Scientific and feasible construction plans must be established for reset installation after new or overhaul. According to the requirements of customers, CHAENG selects the appropriate wood mold for modeling design, and adopts CAE simulation pouring before pouring, strictly in accordance with wood pattern -molding-pouring-finishing grinding-out of pit and cleaning-heat preservation-flaw detection-final products-loading, casting high quality ring gear castings. And CHAENG uses a unique heat treatment technology in the casting, which optimizes the ring gear structure, improves the hardness, and greatly enhances the wear resistance and impact resistance of the product.
The large girth gear is the heart component of the rotary kiln operation. The installation quality directly affects the stability of the rotary kiln drive system, the stability of the rotary kiln operation, the service life of the kiln lining and the rotary kiln operation rate. In order to make the large girth gear work better, after it has been in operation for a period of time, it is necessary to clean the waste oil, thoroughly remove the dirt, wipe it with clean gauze, and then clean the oil and lubricating oil. Smear, always ensure that large gears are carried out in a clean and lubricated environment, effectively extending the life of the large ring gear and improving the production efficiency of the enterprise.
