planetary speed reducer for yaw and pitch drive

Features:

1.Rugged bearing
2.Accurate transmission ratio
3.Planet modular structure, smooth transmission, high efficiency,
4.Highly favored by domestic and foreign manufacturers of wind power

MW Wind Turbine is new national energy equipment to be greatly developed. Yaw and Variable pulp gearbox, as one of its key parts, is of great transmission ratio, big transfer torque. Because of operating at extreme conditions, Yaw and Variable pulp gearbox is required to be of high reliability, long life. Domestic MW Wind Turbines are mainly imported, which seriously impede the development of national MW Wind Turbine. Yiliya Hydraulic Transmission Co. Ltd. has overcome the design, production and technology test of multi-level planetary transmission, successfully developed the new product meeting the standards of the foreign classification society by cooperating with other companies and has passed Transmission performance and fatigue life test.

The performance indicators of gearbox have reached international advanced level. The comprehensive performance of the test platform leads at home, fills national gap, and makes the key parts of MW Wind Turbine localized realized.

In the early 1980s, Anhui Yiliya (YILIYA) was introduced Germany and Italian technology for research and production of Travel Drives, Swing Drives and Winch Drives on excavator. By now the company has had about 30 years' history on manufacturing Planetary Gearboxes, Hydraulic Motor, Hydraulic Winch, Hydraulic Cylinder, Crawler Chassis, and therefore it accumulated plenty of manufacturing experience. It is an international and professional transmission equipment company whose products are manufactured according to international standard, through imitating and emulating by microcomputer and optimization by Finite Element Analysis. Our products are of high safety and superior transmission performance. Because of high quality and brand reputation, our products have been widely used in various Engineering Machinery(Rotary Drilling Rig, Crane, Pile Driver, Drilling), Mining Machinery(Tunneller, Coal Mining machine), Ship(Deck machinery), Metallurgic Equipment, High-speed Rail Equipment (Beam Carrier, Beam Lifting machine), Geological Exploration, Mining Machinery, Gardens, Military, Wind Power (Yaw and Pitch Drive, Wind Power Lifting equipment) and other areas, and middle-and-large tonnage Crawler Chassis have been listed as our company's key products. Before 2006, our planetary gearboxes and hydraulic cylinders were mainly used for excavator. Now we apply the successful experience in the excavator to the research and production of components in different kinds of engineering machines and go into mass production of planetary gearbox (travel drive, swing drive, winch drive), heavy industry low-speed high-torque planetary gearbox, hydraulic winch, hydraulic cylinder, and crawler chassis. The main connection size of our products are of international standard. With the cumulative manufacturing experience, Yiliya improves products’ internal structure continuously. We constantly upgrade the design drawings so as to fully satisfy the customers’ requirements and pursue the excellence of transmission performance, which is bound to advance Yiliya Hydraulic Transmission Equipment Company to be in line with the international conventions. Superb technology, professional team, constant innovation, Yiliya is always working hard to provide effective service timely whenever the customers need. Our products can be a good substitute for Germany Rexroth, O & K, Italy Bonfiglioli, Brevini and America FAIRFIELD, RR, Japan Teijin and so on.
