TV-SAT 是西德首颗直播卫星,计划1985年7月发射,它将为西德提供电视和无线电广播节目。研制中的 TV-SAT 卫星使用了适当的机械束来满足空间任务的主要要求。运动机构 TV-SAT 卫星采用三轴稳定方法,因此要用动量轮对卫星的姿态进行控制。这种动量轮一般重6公斤左右,转速约3000转/分,采用外径为40毫米的径向止推滚珠轴承。这种轴承的保持架用酚醛树脂编织物做成。树脂结构能贮油。贮油器亦用
TV-SAT, the first direct broadcast satellite in West Germany, is scheduled to launch in July 1985 and will provide television and radio broadcasts to West Germany. The developing TV-SAT satellite uses the appropriate mechanical beam to meet the major requirements of the space mission. Movement mechanism TV-SAT satellite using three-axis stabilization method, so use the momentum wheel to control the attitude of the satellite. This momentum wheel generally weighs about 6 kg, speed of about 3000 r / min, using an outer diameter of 40 mm radial thrust ball bearings. This bearing cage made of phenolic resin braid. Resin structure to oil storage. Oil storage is also used
