The main component of the celestial globe is a hollow bronze globe, with crisscross grids on the spherical surface, which are used to delineate the exact position of celestial bodies.

整个铜球可以绕一根金属轴转动，转动一周代表一个昼夜，球面与金属轴相交于两点：北天极和南天极。两个极点的指尖，固定在一个南北正立着的大圆环上，大圆环垂直地嵌入水平大圈的两个缺口内，下面四根雕有龙头的立柱支撑着水平大圈，托着整个天体仪。

The shaft is mounted in the pump housing by axially spaced conical bearings, each bearing including a first element fixed on the shaft with a first conical bearing surface concentric with the axis, a coacting second element carried by the housing with a second conical bearing surface concentric with the axis and slidably engaging the first bearing surface and a spring forcing the elements together.

所述轴由轴向地间隔开的锥形轴承安装在所述的泵外壳中，每一轴承包括：第一元件，固定在所述轴上，具有与所述轴线同心的第一锥形轴承表面；共同作用的第二元件，由泵外壳承载，具有与所述轴线同心的第二锥形轴承表面，该第二锥形轴承表面可滑动地啮合所述第一轴承表面；和弹簧，将所述元件压在一起。

The aerostatic bearing levitates the actuating rod with four radial air inlets on each side. The frictionless aerostatic guide can improve the actuating rod is electromagnetically driven by a fixed solenoid and a actuating solenoid. Through adjusting the axial position of the actuating solenoid, the actuating stroke can be fine regulated.

双列径向供气之气静压轴承提供致动轴作径向的支撑，其低摩擦之特性有助於提升定位精度，致动轴两端外侧设有固定线圈与致动线圈，调整致动线圈轴向位置可以改变致动器最大行动范围。

Pump: RCDL / RCDLF standards for the installation of the electrical non-self-priming vertical multi-stage centrifugal pumps, electrical axis through the pump head and shaft connected by coupling, rod bolts to cylinder pressure, over-current components in the pump head and out of fixed paragraph water between the pump inlet-outlet in the same line.

泵： RCDL/RCDLF为安装标准电机的非自吸立式多级离心泵，电机轴通过泵头用联轴器与泵轴联接，拉杆螺栓将耐压筒、过流部件固定在泵头和进出水段之间，泵进出水口在同一直线上。

The rolling wheel of D51 rolling loop machine is fixed with an expansion ring and its axial locating accuracy is high so the processing difficult of rolling wheel is reduced.

D51型辗环机辗压轮系采用涨圈固定，轴向定位精度高，简化了辗压轮的机械加工；下支承轴端圆锥孔后面设有方孔，辗压辊与下支承轴的联接可靠，更换容易，减少了非生产性工作消耗，提高了劳动生产率。

The bearing is fixed on the shaft by setscrews in the inner ring, eccentric locking collar or adapter sleeve so that it decreases the precision requirement of the shaft and makes installment and replacement convenient.

带座外球面轴承的内径采用&+&公差，与轴形成间隙配合，通过内圈上一侧的顶丝、偏心套或紧定套，把轴承固定在轴上，降低了对轴的精度要求，安装或更换轴承极为方便。

The XTR rotor is a two-piece construction with a steel brake surface on an aluminium carrier. The rotor mounts on a splined hub and is held in place by a lockring that takes the same tool as Shimano\'s cassette lockring.

XTR的刹车盘是一片由中央的铝制支撑盘和铆接在外侧的钢质刹车环组成，是用类似Shimano固定小飞的方式固定在轴皮外侧上：用一个爪轮来固定外侧的圆形锁紧环。
