NTN Developed “Motorized Linear Module for Tracking System of Solar Heat/Solar Light Power Generation”

NTN Corporation (hereafter, NTN) has developed the “Motorized Linear Module for Tracking System of Solar Heat / Solar Light Power Generation*” with high precision positioning technology for use in solar heat and solar light power generation facilities.

Tower type solar heat power generation plants designed to use the sun’s energy effectively utilize a reflecting mirror to track the movement of the sun, with heat from the solar light collected at the central tower used to generate power. Devices used to track the sun are generally designed so that the angle of elevation moves linearly, with rotation and drive moving around the horizontal angle.

Until now, pneumatic and hydraulic cylinders had been used as the linear actuators of the drive mechanism for the angle of elevation due to their simple construction and high mass-production capabilities. Yet these designs required external compressors, special piping and other equipment connected to each cylinder, as well as significant power supplied to them. It was also difficult to completely eliminate air or oil leaks from the cylinders or piping, which subsequently required time and cost to conduct maintenance inspections and repairs.

The “Motorized Linear Module for Tracking System of Solar Heat / Solar Light Power Generation” developed by NTN uses a linear module type cylinder powered by an electric motor drive system. The use of a ball screw for the feed screw gives the module a high repeatability of the position and durability for extended use. Grooves have been machined into the track surface on the inner surface of the body that forms the part of straight guide, and a rolling bearing as the guide roller to ensure smooth linear guidance and a high rigidity.

Solar heat power generators are suited to larger areas of land with long hours of sunlight such as deserts. The developed product can be used under the tough environmental conditions found in desert areas, as it features a dust seal to prevent the entry of dust and other foreign matter, and comes with protection tubes to protect piping from UV rays and heat.

The developed product can also be used for solar light power generators, and installation of tracking systems mounted to solar panels are expected to increase the amount of power generated by 1.6-fold compared to fixed systems.

NTN has already supplied the developed product to manufacturers of solar heat power generation equipment for evaluation testing, and is focusing on sales activities in global markets.

GGB自润滑轴承替代滚动轴承

GGB自润滑轴承替代滚动轴承(0)

This article, press release or announcement is translated from BearingNEWS (www.bearing-news.com) publications and adapted for the Chinese bearing industry professionals. << Replacing Roller Bearings with GGB Plain Bearings >> 当今GGB轴承技术提供的先进滑动轴承与滚动轴承相比具备很多优势。当今GGB轴承技术提供的先进滑动轴承与滚动轴承相比具备很多优势。 除了它们的简单设计和成本效益,滑动轴承提供更大的负载能力,更大空间,重量更轻,更紧凑的设计节省重量。此外他们补偿偏差,减少边缘载荷和抑制噪声和振动。因为它们不包含运动部件,轴承也提供更安静的工作环境,更可靠的性能,并且只需要很少维护。 这些优势是由设计工程师在广泛应用滑动轴承替换滚动轴承来实现的。这些应用包括风力涡轮机,农业设备,转向系统,空调压缩机,发动机摇臂,节流阀,变速箱和传动系统,和头目,其中。潜在应用包括海上浮式生产储油系统,制动机构,发电机和起动机。 滑动轴承也不是适合所有应用。尤其是在需要超低摩擦和/或高精度轴位置。但是在涉及高载缓慢的振荡运动中滑动轴承就显示出了优异性,因为滚动轴承的滚动部件脱落可能会导致过早失效。 用GGB轴承取代传统的滚动轴承可以给用户提供技术和竞争优势。更大的接触面积提供高承载能力和抗疲劳破坏,冲击和边缘载荷。轴承的摩擦特性也抵抗惯性和高速滑行,滚子轴承的主体,他们容忍偏差优于许多滚动元件设计。 紧凑的整体结构和较小的外壳,节省空间和重量。简单的压入配合几乎消除了安装的潜在损害。转换为滑动轴承还可以降低部分成本,低风险装配。 完整替换滚动轴承与普通轴承的文章,请点击 http://machinedesign.com/article/plain-bearings-outperform-rolling-element-bearings-0407 更多信息请联系 china@ggbearings.com
