Machined `crown rack' or `Formate' toothed internalbevels and their conjugate meshing gears seem likely tobe the preferred option for these pitch cone angles.The design layout for a rotary actuator that is based onthese parameter values is shown in Fig. 9. The depictedassembly consists of relatively few separate components,namely, the input shaft YX with its machined inclined the shaft yY which is machined integral with theinternal bevel gears 2 and 4; two tapered roller bearingraces that support yY on the inclined boss of YX and areheld in place there by
the fixedshaft 1X, of which gear 1 is an integral part, the outputshaft 3X, of which gear 3 four ballbearing races that are able to tolerate a combination ofboth axial and radial loads in supporting the YX and 3X the gear case and its end cap, and gear caseattachment b and the 1X shaft.An assembly sequence for these components is first toalign the shaft 1X with its gear case register and to lockit in place using its attachment bolts, then to press homethe left-hand ball race for the shaft YX in the gear case next, the shaft 3X and its supporting ball racesis pressed home in the gear case end cap, and the righthandball race for the shaft YX is pressed home in thehousing in the face of the 3X the right-hand rollerbearing for the shaft yY is now pressed home against thestop on the inclined boss of shaft YX and the shaft yY isthen pressed home on this tapered roller bearing until theyY shaft stop is encountered, at which stage the left-handroller bearing is pressed home over the inclined boss andinto the shaft yY until
the threadedkeep ring is then screwed on the inclined boss to lock the right-hand end of the shaft YX isnow pressed home in the roller bearing race in the faceof shaft 3X and the end cap carrying this assemblypresses home the shaft YX into the left-hand rollerbearing race until the cap meets its register in the gearcase and is bolted in place, shimmed as necessary toensure free rotation of input and output shafts and theengaged gears.
This layout is in the CABIN configuration whichensures that those components subjected to the highestrotational speed are closest to the axis of rotation, whilethe small value of è and disposition of the yY gears andbearings ensures the minimisation of dynamic unbalanceeffects. The extensive use of ball and tapered rollerbearings supports for the rotating components minimizesfriction losses and helps to ensure a high mechanicalefficiency for the transmission system as a whole. Inprinciple, the system should be operable in the reversedirection, with shaft 3X as the input and shaft YX as theoutput, but could prove to be inoperable without someform of `kick-start' rotation of the output to overcomeresidual friction and backlash effects that are magnifiedby the high transmission ratio.
A rotary actuator of this kind, where an input rotationof 3608 produces an output rotation of 0:18, has particularapplications for the control of azimuth and inclination ofan astronomical telescope, a radar dish or a gun turret,or other such applications where precise indexing isrequired.
This same CABIN layout can be adapted for transmissionsystems covering a wide range of transmissionratios, each of which requires an appropriate set ofmeshing gears and associated YX shaft. One suchexample is shown in Fig. 10 for which the relevantparameters are

用机器制造的“冠机架’或“甲酸盐’齿状内部bevels和他们的共轭捕捉的齿轮可能似乎对这些的首选沥青锥体渔的be。The根据的一个摆动马达的设计版面these参数值在图9.显示。 被描述的assembly包括相对地少量分开的组分， namely，与它的用机器制造的倾斜的的输入轴YX 是与的用机器制造的积分式的轴yYinternal斜齿轮2和4; 二圆锥滚柱轴承支持在YX倾斜的上司的yY并且是的races那里到位held由一个穿线的保留圆环; 固定的shaft 1X，哪些齿轮1是整体部分，产品shaft 3X，哪些齿轮3是整体部分; 四个球能容忍的组合的bearing种族在支持YX和3X 的both轴向和辐形装载 齿轮箱和它的节流阀端盖和齿轮箱节流阀端盖的attachment螺栓; 并且1X轴。An这些组分的装配次序是第一对align与它的齿轮箱记数器的轴1X和锁it到位使用它的联接螺栓，然后按家庭轴的YX the左手滚珠轴承座圈在齿轮箱 其次，轴3X和它支持的滚珠轴承座圈在齿轮箱节流阀端盖按的在家is和右手轴的YX ball种族在被按在家在3X轴面前的 右手路辗轴的yY bearing现在被按在家反对在轴YX和轴yY倾斜的上司的stop是then在直到的这个圆锥滚柱轴承按了在家yY轴中止遇到，在哪些阶段左手roller轴承被按在家在倾斜的上司和into直到这中止的轴yY被到达; 穿线的keep圆环在倾斜的上司然后被拧紧锁the整体到位; 轴YX的右手末端是now在面孔的滚柱轴承种族按了在家of轴3X和运载这汇编的节流阀端盖presses回家轴YX入左手路辗直到盖帽的bearing种族遇见它的在齿轮的记数器case和到位被闩上，如所需要填对ensure释放输入和输出轴和的自转engaged齿轮。

This同样客舱设计图可以为传输适应systems盖各种各样传输ratios，其中每一要求适当的套meshing齿轮和伴生的YX轴。 一这样example在图相关的的10显示parameters是
加工`冠架'或`甲酸'齿内部斜面和他们的共轭啮合齿轮似乎可能这些球场是锥角的优先选择。对于一个旋转驱动器是基于设计布局这些参数值，如图所示。 9。在描绘大会由独立的组件相对较少，即，输入轴与加工斜YX老板;轴yY是积分与加工内部锥齿轮2和4;两个圆锥滚子轴承支持yY对YX倾斜的老板，是比赛举办地点由一个线程保持环存在，而且固定1X的轴，齿轮，其中1是一个不可分割的组成部分，输出轴3倍，其中齿轮3是一个不可分割的组成部分; 4球那些能够忍受组合轴承套圈在支持YX与3X都轴向和径向载荷轴的齿轮箱和端盖和齿轮箱附件为端盖螺栓以及1X的轴。为这些组件的装配顺序是首先配合它的齿轮箱登记和锁轴1倍它有何用螺栓及其附件，然后按家庭为在齿轮箱轴YX左手球比赛住房，接下来，轴及其支持3倍球比赛按下家中的齿轮箱端盖，和右手球比赛的轴YX按下家中房屋在井筒工作面3倍;右边滚子轴承的轴yY现在压在主场对阵停止对老板YX轴倾斜和轴YY是然后按下这个圆锥滚子轴承回家，直到yY遇到轴停止，在这阶段的左手滚子轴承按家中的老板和倾斜到轴yY直到这一站是达成协议;螺纹保持环然后在倾斜老板锁拧在整个地方;轴的YX右手端现在家中压在脸上滚子轴承套圈轴的3倍和贯彻这次大会的端盖按家进入左边的辊轴YX轴承套圈，直到上限符合其注册的齿轮案件是在地方螺栓，必要时要匀确保输入和输出轴和自由旋转从事齿轮。这是在客舱布局的配置确保这些组件受到最高转速是最接近的旋转轴，而在电子和处置小齿轮和YY价值轴承，确保了动态不平衡最小化影响。该球和圆锥滚子广泛使用轴承的旋转部件支持减少摩擦损失，并帮助确保高机械效率为整个传输系统。在原则上，该系统应具有可操作性的反方向，以作为输入和轴YX轴3倍输出，但可能被证明是没有一些不可操作形式`发动'的输出转速，以克服残余摩擦和强烈反应被放大效应由高传动比。一个这样的，旋转驱动器在输入轮换对3608产生的0:18输出转速，具有特殊的申请的方位和倾角的控制1天文望远镜，雷达天线或炮塔，精确索引或其他地方是这样的申请需要。此相同的客舱布局可以适应传输系统涵盖了广泛的传播比率，每个都需要一个适当的设置齿轮啮合及相关YX轴。其中一个例如图所示。而有关10参数
