项目摘要

This paper is described about doing a very minute plastic gears in the initiation, using a pressurization heat shrinkage. Because it minute-izes a mechanical system, the minuter movement can be realized. Plastic has the other side, some defects which has a lot of merits, too. Experimentally, it pressed at the plastic board to have made filmy with the numerous axis ranging method. After that of a high precision gear is won in pressing., it gets a very minute gear by the pressurization heat shrinkage. Because the numerous axis is uniform about the shrinkage percentage, machine manufacture precision is kept just as it is. The manufacturing of the gear with module 0.04, equal to or less than 1mm of outside diameters became possible as a result of the experiment. The tooth shaped precision, the size precision, too, are high and can get the gear of the high precision with is not so far. These gears can be one with big tooth width and a lot of application is expected. In 1995, it designed and it manufactured a press jig for the axis hole manufacture. It manufactured a higher precision gear by being first manufacture and doing the revision of the clearance of the die for the pressing and the wallop and the revision of the loss quantity of the wallop and the study in 1996 could manufacture in the pressurization heat shrinkage as the secondary manufacture. As the result of the experiment, it measured the outside diameter of the very minute plastic gear and the caliber of the axis hole. The high precision gear could be gotten and reappear-ability by the manufacture was gotten. with the probability of these manufacture technique, the manufacture of the microgear pump became possible. By this way of manufacturing, in the future, the development of the equipment which used a gear pump is expected.

本文介绍了做极微小塑料齿轮的起爆，采用加压热收缩。由于它使机械系统分分钟化，所以可以实现分分钟运动。塑料也有缺点，但也有很多优点。实验上，用多轴测距法在塑料板上压成薄膜。在此之后，在压制中获得高精度齿轮。它通过加压热收缩得到一个非常小的齿轮。由于众多轴的收缩率是均匀的，所以机器的制造精度保持不变。通过实验，可以制造出外径等于或小于1mm的模数为0.04的齿轮。齿形精度、尺寸精度也都很高，能得到高精度的齿轮用是迄今为止没有的。这些齿轮可以是一个大的齿宽和大量的应用是预期的。1995年，自行设计制造了一种轴孔加工用冲压夹具。1996年研究了加压热收缩作为二次加工可以进行加工的方法，通过对压模和冲击模间隙的修正和冲击损耗量的修正，制造出了精度较高的齿轮。作为实验的结果，测量了极微小塑料齿轮的外径和轴孔的口径。通过加工获得了高精度的齿轮，并具有良好的再现性。有了这些制造技术的可能性，制造微型齿轮泵成为可能。通过这种制造方式，对今后使用齿轮泵的设备的发展进行了展望。
