| 传动分类比较： Drive classification comparison: 1、丝杠传动，优点：测试精度，可重复性高，缺点：价格昂贵，导致拉力机整机成本偏高； 1. Lead screw drive, advantages: test accuracy, high repeatability, shortcomings: high price, resulting in high cost of the whole tractor; 2、齿条传动，优点：价格便宜，可降低拉力机成本，缺点：测试精度低，可重复性较差。 2. Rack drive, advantages: low price, can reduce the cost of tractor, shortcomings: low test accuracy, poor repeatability. 拉力试验机的丝杠，对拉力精度测量具有决定作用。 The lead screw of the tension testing machine plays a decisive role in measuring the tension accuracy. 丝杠的分类比较： Classification and comparison of lead screw: 1、滚珠丝杠，优点：测试精确度最高，缺点：性能受制于电脑伺服系统，整套仪器价格偏高； 1. Ball screw, advantages: the highest test accuracy, shortcomings: performance is subject to computer servo system, the price of the whole set of instruments is high; 2、梯形丝杠，优点：达到一般要求精度（0.5-1%），价格相对便宜，缺点：不适用测试精度要求高的测试； 2. Trapezoidal lead screw, advantages: to meet the general requirements of accuracy (0.5-1%), the price is relatively cheap, shortcomings: not suitable for testing with high accuracy requirements; 3、一般丝杠，优点：可以达到软包装所要求的精度，缺点：不适用测试精度要求高的测试。 3. General lead screw, advantages: can achieve the accuracy required by soft packaging, shortcomings: not suitable for testing with high accuracy requirements. |
