NSK Bearing Helps Carbon Neutrality And Meets New Opportunities For Wind Development

2021 Beijing International Wind Energy Conference and Exhibition (CWP2021), the most influential event in China's wind power industry, will be held as scheduled at the China International Exhibition Center (New Hall) in Beijing from October 18th to 20th. NSK Investment Co., Ltd. (hereinafter referred to as NSK) will bring new wind power technology and new products to the exhibition, and invite you to help "carbon neutrality".

In recent years, extreme weather has occurred frequently around the world, and it is urgent to deal with climate change. Accelerating the energy transition to build a green and sustainable economic form has become a global consensus. As one of the renewable, pollution-free green and clean energy sources, wind power has become the main force in achieving the goal of carbon neutrality in China.

CHINA WINDPOWER 2021

Adhering to the corporate philosophy of "maintaining the global environment", NSK has long been committed to the research of bearings for wind power generation. Its products are widely used in the main shaft of the windmill, the gearbox of the speed increaser, the generator, the pitch and the yaw and other systems. Continuously and steadily produce clean energy and contribute to achieving carbon neutrality at an early date.

In this wind energy exhibition, NSK bearing will not only exhibit a variety of high-reliability and long-life rolling bearings that ensure the stable and reliable operation of windmills, but also a new member of the NSK Group-the world-renowned condition monitoring system brand B&K Vibro will also make a wonderful appearance, bringing unique vibration conditions. The monitoring program, together with NSK, contributes to carbon neutrality and welcomes new opportunities for wind development.

Cylindrical roller bearing without outer ring for planetary gear of main gearbox

NSK's outer ring-less cylindrical roller bearings have realized a compact design for planetary gear bearings by omitting the outer ring of the bearing. It not only avoids the creep phenomenon that is likely to occur in the outer ring of the planetary gear bearing, but also leaves more design space for the roller. In addition, NSK can provide customers with design specifications for the inner diameter surface of the gear to give full play to the performance of the bearing.

High-load capacity roller bearings for high-speed shafts of wind power generators

NSK's high-load bearing series adopts ultra-thin copper alloy turning cage to increase the number of rollers; and by optimizing the shape of the bus bar of the roller, the maximum contact stress between the roller and the ring is reduced. In the case of keeping the bearing dimensions unchanged, the load-carrying capacity can be improved, and the bearing life can be extended by a maximum of 2.3 times.

Ultra-large tapered roller bearing for planetary carrier of wind power generation

NSK's super-large size series tapered bearings are specially designed for the planetary carrier of the large-megawatt wind power main gearbox, which can bear large radial and axial loads at the same time, and NSK can recommend the pre-tightening force during installation to improve rolling The load distribution between the bodies gives full play to the bearing capacity. NSK also specially developed a stamped steel cage for the bearing. Compared with the pin-type cage, it not only improves the strength of the cage, but also reduces the bearing processing cost and the risk of abnormalities on the bearing surface.
