試驗(yàn)機(jī)是在各種條件、環(huán)境下測(cè)定金屬材料、非金屬材料、機(jī)械零件、工程結(jié)構(gòu)等的機(jī)械性能、工藝性能、內(nèi)部缺陷和校驗(yàn)旋轉(zhuǎn)零部件動(dòng)態(tài)不平衡量的精密測(cè)試儀器，可以對(duì)材料進(jìn)行拉伸、壓縮、彎曲、剪切、扭轉(zhuǎn)、沖擊、疲勞、蠕變、持久、松弛、磨損、硬度等試驗(yàn)。近年來(lái)，試驗(yàn)機(jī)行業(yè)技術(shù)突飛猛進(jìn)。試驗(yàn)機(jī)向著兩個(gè)方向即超微外力檢測(cè)與超大外力檢測(cè)發(fā)展。高檢測(cè)精度、高靈敏度、運(yùn)動(dòng)平穩(wěn)、易于操縱是目前試驗(yàn)機(jī)的主要發(fā)展方向。

     濟(jì)南一諾試驗(yàn)機(jī)根據(jù)從業(yè)15年的經(jīng)驗(yàn)首先講了試驗(yàn)機(jī)的基本定義、分類與一些重要商的成果。第二部分論述了所想到的四種方案并對(duì)這些方案優(yōu)缺點(diǎn)作了分析和對(duì)比。前三種方案均為利用滾珠絲杠，最后一種則利用液壓。第三部分則是說(shuō)明了試驗(yàn)機(jī)的主要機(jī)械傳動(dòng)部分的設(shè)計(jì)以及對(duì)它們的校核過(guò)程。試驗(yàn)機(jī)的傳動(dòng)部分主要由蝸輪蝸桿、錐齒輪、滾珠絲杠三部分組成。經(jīng)過(guò)校核后所有設(shè)計(jì)均符合要求。用ProE軟件完成試驗(yàn)機(jī)的三維總裝圖，然后得到了整個(gè)試驗(yàn)機(jī)的二維裝配圖和蝸輪蝸桿、錐齒輪、軸等二維零件圖。

    Jinan YiNuo Testing machine Universal testing machine

Test machine in various conditions and environment in metal materials, non-metallic materials, machinery accessory, engineering structures such as mechanical properties, technics performance, Internal defects and checking dynamic imbalance rotating parts of sophisticated testing equipment, such as materials tension, compression, bending, shear, reversing, impact, fatigue, creep, lasting and relaxation, wear, hardness tests. In recent years,the technic of the test machine industry advances rapidly. Test machine is the direction toward the development of the super-tiny force detection and the development of super-large external force testing. Detection of high-precision, high sensitivity, smooth motion, easily operated test machine is the main development direction presently.

Jinan YiNuo Testing machine first summarizes the test machine's basic definition, classification, and some important domestic and foreign manufacturers results. The second part, discussing about the experiences of the four projects as well as advantages and disadvantages of these projects are analyzed and compared . The foregoing three programs are the use of ball screw,.In comparison with each other decide the first option. The third part is the experiment, the major part of the mechanical drive design and the process of checking them. The main drive system of the test machine includes the worm,taper gear, ball screw three components. After checking  all the design had complied with the request. The three-dimensional assembly drawings of the test machine are finished by the soft called PROE.Then,export the planar drawings,such as worm gear&worm,taper gear,shaft and so on. ?
