Explore our high-performance slewing gears engineered specifically for high overturning moment resistance and sub-milliradian tracking precision.
Concentrated Solar Power (CSP) tower plants utilize a sprawling field of dual-axis tracking mirrors, known as heliostats, to focus sunlight onto a central receiver located atop a tower. The key technical challenge in CSP operation is maintaining extreme precision under volatile environmental conditions. Even a minor tracking error of 1 milliradian (mrad) can displace the reflected solar beam by several meters at the central receiver, leading to drastic drops in thermal efficiency and potential damage to the receiver components.
Jiangsu Manchen Transmission Technology Co., Ltd. addresses this industry-wide challenge by designing and manufacturing heavy-duty slewing bearings and integrated horizontal rotary drives. By optimizing the contact profiles, eliminating gear backlash, and utilizing advanced sealing technologies, our products ensure that heliostats remain locked onto their targets despite strong desert wind gusts and extreme thermal variations.
Our customized solutions provide the structural stability, overturning moment resistance, and low-backlash operation that global EPC contractors demand to maximize the return on investment of utility-scale solar thermal power projects.
Understanding user intent and engineering expectations from project developers and global contractors.
Heliostats feature large surface areas that act like sails. In desert storm events, the slewing drive must handle massive dynamic overturning moments and radial forces. Manchen slewing bearings use customized heat treatment and deep-hardening raceways to prevent plastic deformation.
Solar tower projects are located in arid, dusty, and sandy areas. Sand particles act as abrasives that quickly destroy bearings if they penetrate the raceway. Our specialized double-lip NBR seals keep dust out and grease in, reducing site maintenance costs to almost zero.
As the solar thermal market scales, standardizing parts is crucial. Our rotary drives support standard motor interfaces, allowing project developers to swap out electric or hydraulic actuators easily without replacing the main slewing structure.
