磨料磨損試驗(yàn)機(jī)的設(shè)計(jì)
摘 要
目前磨料磨損試驗(yàn)機(jī)的品種繁多，也有不少人在研究新型的試驗(yàn)機(jī)。在國(guó)內(nèi)的相關(guān)研究中則廣泛使用的試驗(yàn)機(jī)有滾子式磨損試驗(yàn)機(jī)、四球式磨料磨損試驗(yàn)機(jī)、往復(fù)式磨料磨損試驗(yàn)機(jī)、磨損試驗(yàn)機(jī)、盤銷式磨料磨損試驗(yàn)機(jī)等。磨料磨損試驗(yàn)的目的是為了對(duì)磨損現(xiàn)象及其本質(zhì)進(jìn)行研究，正確地評(píng)價(jià)各種因素對(duì)磨料磨損性能的影響，從而確定符合使用要求的摩擦副元件的最優(yōu)參數(shù)。
我所設(shè)計(jì)的是磨料磨損的試驗(yàn)機(jī)。是用電機(jī)帶動(dòng)帶輪為驅(qū)動(dòng)，利用帶式傳動(dòng)使整臺(tái)設(shè)備運(yùn)轉(zhuǎn)。這種試驗(yàn)機(jī)是進(jìn)行磨料磨損的有效設(shè)備，廣泛運(yùn)用于對(duì)各種高速刀具的磨損性能進(jìn)行測(cè)試和評(píng)價(jià)，是高速切削和新型刀具材料研制開(kāi)發(fā)和應(yīng)用的必備設(shè)備。該設(shè)備是高速加工和刀具材料研究方向研究工作急需的基礎(chǔ)設(shè)備，該設(shè)備可以擴(kuò)展該學(xué)科的研究領(lǐng)域和提高研究水平。是綜合各種試驗(yàn)機(jī)的一種先進(jìn)的設(shè)備。

Abstract
The abrasive wear test machine of the variety, there are a lot of people in the study of new type of testing machine. In the domestic related research is widely used in the testing machine has a roller type wear testing machine, four ball friction and wear testing machine, reciprocating friction and wear testing machine, cutting type friction, wear testing machine, friction test machine. Friction and wear test is aimed on the friction and wear phenomenon and its essence is studied, a evaluation of various factors influence on friction and wear properties, thereby determining the requirements of the optimal parameters of friction pair components.
What I design is at a high temperature abrasive wear testing machine. Is driven by a motor belt wheel for driving belt transmission, using the whole device operation, this machine is of high speed friction and wear behavior of effective equipment, is widely used for various high temperature friction and wear properties of high speed cutting tool for testing and evaluation, is of high speed cutting and new cutting tool materials research and development and application of the necessary equipment. The device is of high speed machining and tool material research direction research work needed infrastructure equipment, the equipment can be extended to the field of study and improve research level. Is a comprehensive test machine is a kind of advanced equipment.
Key words：friction；testing machine；high temperature；high-speed

1.1 設(shè)計(jì)的目的和意義
隨著冶金、礦山、電力以及工程機(jī)械等行業(yè)的發(fā)展，人們對(duì)磨損危害的認(rèn)識(shí)有了相當(dāng)?shù)奶岣?。為了弄清磨損機(jī)理以減少有害的磨損，各國(guó)學(xué)者對(duì)材料在常溫下的各種磨損問(wèn)題均進(jìn)行了大量的研究，但對(duì)于材料在高溫下的磨損問(wèn)題至今卻研究的較少
