Due to the increasing demand for large precision gears in domestic ships, wind power, nuclear power, locomotives, metallurgy, mining and military industries, there is an urgent demand for high-precision gear grinding machines for R&D and processing of large precision gears: 1 Wind power industry growth rate Gearbox: Internal gear with φ 1 500mm and accuracy of 5 or higher is required. 2 Shipbuilding gearbox: Need φ 2 500mm, precision gear of 5 or more precision. 3 large radar turret: high precision gears above φ 2 000mm are required. 4 cement center drive mill: high precision gears above φ 3 000mm are required. 5 Bengang 1700 hot strip mill: high precision gears above φ 2 000mm are required.
However, at present, it is not possible to independently manufacture large-scale precision gear grinding machines with a precision of 4 or higher, and rely entirely on imports. Based on this situation, it solves the design and manufacturing problems of large-scale high-precision gear grinding machines and breaks the monopoly position of foreign large-scale gear grinding machines. The design and manufacturing level of China's large-scale high-precision CNC forming gear grinding machines has reached international advanced level, in line with the national medium and long-term. Scientific and technological development planning goals.
Shaanxi Qinchuan Machinery Development Co., Ltd. independently developed the highest precision CNC with a grinding diameter of 2 500mm according to the national medium and long-term scientific and technological development planning target and the domestic market demand for large-scale high-precision hard-toothed gear grinding equipment. Forming gear grinding machine - YK73200 gear grinding machine (with internal grinding head).
YK73200 grinding machine
YK73200 CNC Forming Wheel Grinding Machine is a high precision gear precision grinding machine which is ground by forming method.
Main parameters of the machine tool: maximum tip diameter 2 000mm (maximum φ 2 500mm); minimum root diameter 300mm; modulus 2～35; no limit of teeth; maximum straight tooth width 1 000mm; helix angle range ±35°; Load (including fixture) 20 000kg; processing accuracy is 4 (GB/T10095-2008).
Internal grinding head
(1) Main features of the machine tool:
1The machine tool is fully closed-loop controlled, with various processing objects, gear tooth shape and flexible tooth modification. 2The grinding wheel has AE function in the motorized balance system, which can monitor the grinding and dressing of the machine on-line, and has the function of air-drying and anti-collision. 3 The main bearing of the machine tool adopts static pressure rail technology to ensure the long-term high precision of the machine tool. 4 Workbench adopts double worm double worm gear anti-backlash mechanism, the anti-backlash force is adjustable, the structure is simple and reliable, and the stability of the machine tool is improved. 5The machine tool is equipped in the machine measurement system. It can measure gear tooth shape, tooth direction, circumference, accumulation, etc. on the machine according to requirements, which is convenient for large gear measurement. 6 Self-developed parameterized interface includes packages for grinding calculations, gear common databases, on-machine measurement and other system functions. Friendly interface, easy to operate, practical and convenient.
