It is the micro-external gear pump that the key component of the system, which the speed may reach 3,700 Rpm, the instantaneous pressure may reach 35 MPa as well as the addendum circle diameter only has 14 mm.

系统中的心脏和动力源就是微型外啮合齿轮泵，它的转速可达3700 Rpm，瞬时工作压力可达35 MPa，其中齿轮的齿顶圆直径只有14 mm，同时它也是影响该系统合格率的重要部件之一。

When the powder loading was fixed as 58%,the molded compact of a gearwheel whose addendum circle diameter is 700 μm was obtained with well shape retention.

3μm的羰基铁粉和石蜡基热塑性粘结剂体系，当粉末的装载量为58%时，获得了形状良好的齿顶圆直径为700μm的微型齿轮注射生坯。

The spiral angle of graduated circle was rough estimated by measuring the addendum circle diameter and modified on milling machine.

介绍了精确测绘单一斜齿圆柱齿轮齿形参数的简便方法，即测量公法线长度计算基圆齿距从而查表确定模数和压力角；测量齿顶圆直径估算分度圆螺旋角，用分度头在铣床上修正分度圆螺旋角，并进行误差分析。

Measurements which provide additional insight into the condition of rotating element bearings and gear boxes.

专利测量技术，该技术能提供额外的对转动元件轴承和齿轮箱的洞察能力。

The detail course is to set up the coordinate of the machine and the workpiece, use the intersection of the tool tracing line caused by the adjacent edge in the cutting process as the point on the flank, deduce the function of the flank and program the cutting process of spiral bevel gears using VISUAL BASIC language.

此程序最大的特点就是和实际的加工过程相似——不但齿轮的形成过程和实际相同，而且机床切齿参数的调整过程也和实际一样，因此使用者可以直接在计算机上调整切齿参数，从而根据自己的要求来模拟加工，得到满意的切齿参数，进而在实际机床上获得满意的产品。

In addition to boosting top speed, this 2 Speed Transmission features an adjustable shift point and changeable gear ratios for extra tuning convenience.

此外，以提高最高速度，这2条高速传输功能，可调转向点和复杂多变的齿轮比为额外的调谐方便。

For the structure and installation of complete aerator, please refer to Fig.

整机结构及安装参见图一，齿轮箱结构参见图二。

The node issues occurred in the design is that air valve and the transmission of gear.

设计中碰到的难点问题在于气阀设计，齿轮传动设计。
