Transmission equipment branch company successfully segment ring gear factory mounted
segment type ring gear is one of the productions of transmission equipment branch. It is the latest production independent development designed according to the demand of the market Recently, the first set of segment type ring gear has completed processing in the workshop and assembled. The detection report indicates that all the performance characters are better than the design drawings. Now the products will be currently delivered to the user site for installation and running.
This ring gear with design of power 2X250kw, with ratio of 9.88, is supplying for 4.6x100 meters diameter of rotary kiln Tonghua Jianxin Nickel smelting project, The ring gear material selection of ADI process and a weight of about 13.8 tons, compared with the traditional gear, bearing capacity has been improved, at the same time the weight reduce the nearly 50%.
The top circle diameter of the ring gear is 6840mm and it is divided into 12 segments, each of which is about 1.7m, which ensures the casting accuracy and reduces the machining allowance. In addition, piecewise type gear using single segment processing, using the assembly, so as to avoid the large rolling gear machine and large vertical lathe constraints, using special tool, CNC boring machine in a loaded clamping processing and, making machining precision has been improved, ensure each tooth can be completely exchanged, in the use of the process, when a single tooth segment of accidental damage, new toothed segment can very convenient to replace the damaged parts, the rapid resumption of production equipment, reduce the maintenance cost and the transportation cost.
Segment type big gear ring successfully factory mounted, which is marking the transmission equipment branch under the existing equipment and constantly extends the product processing capacity, improve product processing precision. It is fully reflects company all staff full of courage to make technological innovation and determination, and the company will continue to adhere to the road of technological innovation development and pay close attention to the development of the market trends, accelerating the pace of new product development in order to enter the field of more high-end products.
