The invention discloses a channel type spacecraft solar cell wing sun-oriented device which can effectively solve the problem that an existing spacecraft sun-oriented device is not provided with a manned access, and a feasible solution is provided for solving the problem that in-orbit maintenance of a solar wing is difficult. The invention relates to a channel type sun-facing orientation device for a solar wing. The channel type sun-facing orientation device comprises a tail end involute cambered surface gear, a guide rail gear ring, a roller supporting assembly, a driving assembly, a cabin interface flange, a solar wing adapter flange and other part structural characteristics according to the overall mechanical transmission principle. The method is suitable for spacecrafts which have long service life requirements and need on-orbit maintenance of solar cell wings in the field of manned aerospace. The mode that the eight sets of roller supporting assemblies support the guide rail gear ring in a circumferential distribution mode is adopted, so that a transmission chain can be offset, and then it is guaranteed that a channel for astronauts to go in and out can be reserved in the rotation center of the sun alignment device. The astronaut goes out of the cabin through the central channel of the sun orientation device, and the solar cell arrays on the two sides can be repaired and maintained nearby.
本发明涉本发明公开了一种通道式航天器太阳电池翼对日定向装置,可有效解决现有航天器对日定向装置无载人通路问题,并对太阳翼在轨维修困难给出一种切实可行的解决方案。本发明所述通道式太阳翼对日定向装置包括末端渐开弧面齿轮、导轨齿圈、滚子支撑组件、驱动组件、舱体接口法兰、太阳翼转接法兰等零部件结构特征和整体机械传动原理。本发明适用于载人航天领域具有长寿命要求需要在轨维修维护太阳电池翼的航天器。本发明采用八套滚子支撑组件圆周分布式支撑导轨齿圈的方式,从而使得传动链可以实现偏置,进而保证对日定向装置回转中心可以保留供航天员进出的通道。航天员通过所述的对日定向装置中心通道出舱,可就近维修和维护两侧太阳电池阵。
