| 产品机械主要配置 Main Configuration of Product Machinery 传动，有丝杠传动和齿条传动，前者昂贵，用于高精度，测试重复性高；后者便宜，用于低精度，测试重复性低。 Drive, there are screw drive and rack drive, the former is expensive, used for high precision, high repeatability of testing; the latter is cheap, used for low precision, low repeatability of testing. 丝杠，对拉力精度测量具有决定作用。一般的有滚珠丝杠，梯形丝杠，一般丝杠。其中，滚珠丝杠的精确度最高，但是其性能的发挥要靠电脑伺服系统操作才能发挥，整套价格也比较昂贵。采用一般丝杠和梯形丝杠就可以达到软包装所要求的精度，即0.5－1%精度。传动，有齿轮传动和链条传动，前者昂贵，用于高精度；后者便宜，用于低精度。 Lead screw plays a decisive role in the measurement of tension accuracy. Generally there are ball screw, trapezoidal screw, general screw. Among them, the accuracy of ball screw is the highest, but its performance depends on the operation of computer servo system to play, and the price of the whole set is relatively expensive. The precision required by soft packaging can be achieved by using general lead screw and trapezoidal lead screw, i.e. 0.5-1% accuracy. Drive, there are gear drive and chain drive, the former is expensive for high accuracy; the latter is cheap for low accuracy. 传感器，主要成本在于寿命，光电感应是其中比较先进的技术，一般可用十万次以上，进口和国内部分合资厂家可以达到。 Sensors, the main cost is life, photoelectric induction is one of the more advanced technology, generally can be used more than 100,000 times, imported and domestic joint venture manufacturers can achieve. |
