TAMAM公司研制出一种适合太空船应用的大速率惯导级捷联式动力调谐陀螺,陀螺的参数性能与其自转轴的运动,即沿径向的运动和自身的角运动密切相关,由于采用了独特的轴承装置,才有了如此高性能陀螺。描述最大地降低自转轴运动的方法,包括滚珠跑道几何尺寸的确定,新的整体式内环轴承装置的设计,保持器设计的改进以及使用涂有碳化钛的滚珠,新的设计减少了轴承组件的元件数,提高了工作性能,增大了刚度和自然频率。为检测轴承性能,进行了低速运转力矩和功耗试验,并标定了轴承品质因数,评估了采用涂有碳化钛滚珠的轴承的寿命和工作模式。
TAMAM has developed a large-rate strap-down dynamoelectric tuned gyroscope suitable for spacecraft applications. The gyroscope’s parametric performance is closely related to the motion of its spinning axis, ie its radial movement and its angular movement. Due to the adoption of Unique bearing device, only such a high-performance gyro. Describe ways to minimize roll axis motion, including ball raceway geometry determination, new monolithic inner ring bearing design, cage design improvements, and use of titanium carbide coated balls. The new design reduces the need for bearing assemblies The number of components, improve work performance, increased stiffness and natural frequency. In order to test the performance of the bearing, low speed operation torque and power consumption test were carried out, and bearing quality factor was calibrated to evaluate the service life and working mode of the bearing coated with the titanium carbide ball.
