蜗杆螺纹

Adopting whorl driving can change circular movement to linal movement, and the automatic-locking function can ensure the using security, we develop the structure, analyze the principle, make necessary mechanics analyses, push over the formula, and make it clear that the jack is logical in structure, smart in power knighthead, durable in use, and with a big proportion of output and input.

利用蜗杆传动、螺纹传动，将转动变换为直线运动、将转矩转换为和向力；同时利用螺纹传动的自锁作用，保证使用安全可靠。结果设计出了多功能千斤顶的主要结构，分析了其工作原理，进行了必要的力学分析，推导出数据计算的有关公式等。

To decrease friction between the worm and the nut, balls recirculate in their thread.

为了减少蜗杆和螺母之间的摩擦，滚珠在其螺纹中不断滚动。

These features, along with high-precision processing technologies have helped to miniaturise these products. The micropump is 6.0mm in diameter and 24.0mm in length, the microvalve measures 3.5mm in diameter and 10.3mm in length. The products are small but ensure high functionality by incorporating fluid, structure and magnetic field analysis simulations. Development will contribute to enhanced miniaturisation, an indispensable prerequisite for portable device fuel cells. Through the optimal design of diaphragm operations, valve configuration to prevent fluid backflow, materials and layout, Alps has achieved the effective control of larger amounts of fluid in a smaller chassis for its micropump. The unit also employs low-voltage electromagnetic drive systems, which contribute to easy control and fuel cell system engineering.

Its basic operation method is a tight mother of the lock that the opens to face afterward, can transpose the angle of the pole of arbitrarily, can process the thread that the different helix rises the Cape, this kind of knife pole has the strength and tenacities to process to slice to pare the dosage exaltation labor rate of production and decline low cost etc. to have the progress towards increasing [10]the knife, improve it is a kind of price less that knife have, yielding results the quicker method.

其基本操作方法是拧开其后面的锁紧螺母，可任意调换蜗杆的角度，可加工不同螺旋升角的螺纹，这种刀杆对增加刀具强度和韧性加工切削用量提高劳动生产率及降低成本等方面有所进步，改进刀具是一种代价较少，收效较快的方法。

CNC0630.0640.6130 the Company produced series CNC lathe has all the features of ordinary things, more easily turning a number of complex parts, such as inside and outside the spherical, arbitrary circular , arbitrary cone, public Inch worm thread and so on, have the complete STM function, may be issued and receive a variety of signals to control the automatic processing flow.

本公司生产的CNC0630.0640.6130等系列数控车床具有一般普通的所有功能外，更方便地车削一些复杂零件，如内外球面，任意圆弧面，任意锥面，公英制螺纹及蜗杆等，具备完备的S.T.M功能，可发出和接收多种信号，以控制自动加工流程。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
