中空玻璃生產(chǎn)線粘著磨損，在切向力的作用下，摩擦副表面的吸附膜和服污膜遭到破壞，使表面的輪廓峰在相互作用的各點(diǎn)處發(fā)生冷焊，由于相對(duì)運(yùn)動(dòng)，材料便從一個(gè)表面轉(zhuǎn)移到另一個(gè)表面，形成粘著磨損。在此過(guò)程中，有時(shí)材料也會(huì)再次附著回原表面，出現(xiàn)逆轉(zhuǎn)移，或脫離所粘附的表面而成為游離顆粒。載荷越大，表面溫度越高，粘著的現(xiàn)象也越嚴(yán)重。嚴(yán)重的粘著磨損會(huì)造成運(yùn)動(dòng)副咬死。粘著磨損是金屬摩擦副之間普遍的一種磨損形式。

Adhesive wear occurs in the production line of insulating glass. Under the action of tangential force, the adsorption film and fouling film on the friction pair surface are damaged, causing cold welding of the surface contour peaks at various points of interaction. Due to relative motion, the material is transferred from one surface to another, forming adhesive wear. During this process, sometimes the material will also adhere back to the original surface, experiencing reverse transfer, or detach from the adhered surface and become free particles. The larger the load, the higher the surface temperature, and the more severe the adhesion phenomenon. Severe adhesive wear can cause the motion pair to bite. Adhesive wear is a common form of wear between metal friction pairs.

為了減輕粘著磨損，可采取以下措施：①合理選擇配對(duì)材料。同種金屬比異種金屬易于粘著;脆性材料比塑性材料的抗粘著能力強(qiáng)。進(jìn)行表面處理(如表面熱處理、電鍍、噴涂等)可防止粘著磨損的發(fā)生。②限制摩擦表面的溫度。⑤采用含油性和極壓添加劑的潤(rùn)滑劑。④控制壓強(qiáng)。

In order to reduce adhesive wear, the following measures can be taken: ① Reasonable selection of matching materials. The same metal is easier to adhere to than different metals; Brittle materials have stronger adhesion resistance than plastic materials. Surface treatment (such as surface heat treatment, electroplating, spraying, etc.) can prevent the occurrence of adhesive wear Limit the temperature of the friction surface. ⑤ Use lubricants with oily and extreme pressure additives. ④ Control pressure.

2.中空玻璃生產(chǎn)線磨粒磨損從外部進(jìn)入摩棕面間的游離硬質(zhì)顆粒(如塵土或磨損造成的金屬微粒)或硬的輪廓峰尖，在較軟材料表面犁刨出很多溝紋而引起材料脫落的現(xiàn)象，稱為磨粒磨損。磨粒磨損與摩擦副材料的硬度和磨粒的硬度有關(guān)。有時(shí)選用較便宜的材料，定期更換易磨損的零件，更符合經(jīng)濟(jì)原則。

2. The phenomenon of abrasive wear on the production line of insulating glass is that free hard particles (such as dust or metal particles caused by wear) or hard contour peaks that enter between the friction surfaces from the outside, and plow many grooves on the surface of softer materials, causing material detachment. Abrasive wear is related to the hardness of the friction pair material and the hardness of the abrasive particles. Sometimes choosing cheaper materials and regularly replacing easily worn parts is more in line with economic principles.

3.中空玻璃生產(chǎn)線疲勞磨損，在變接觸應(yīng)力的作用下，如果該應(yīng)力超過(guò)材料相應(yīng)的接觸疲勞極限，就會(huì)在摩擦副表面或表面以下一定深度處形成疲勞裂紋，隨著裂紋的擴(kuò)展及相互連接，金屬微粒便會(huì)從零件工作表面上脫落，導(dǎo)致表面出現(xiàn)麻點(diǎn)狀損傷現(xiàn)象.即形成疲勞磨損或稱疲勞點(diǎn)蝕。

3. Fatigue wear of insulating glass production lines. Under the action of variable contact stress, if the stress exceeds the corresponding contact fatigue limit of the material, fatigue cracks will form on the surface of the friction pair or at a certain depth below the surface. As the cracks expand and connect with each other, metal particles will detach from the working surface of the parts, leading to pitting damage on the surface. This is also known as fatigue wear or fatigue pitting.

為了提高零件表面的疲勞壽命，除應(yīng)合理選擇摩擦副材料外，還應(yīng)注意：①合理選擇零件接觸面的表面粗糙度。一般情況下表面粗糙度值越小，疲勞壽命越長(zhǎng)。②合理選擇潤(rùn)滑油粘度。粘度低的油易滲入裂紋，加速裂紋擴(kuò)展。粘度高的潤(rùn)滑油有利于接觸應(yīng)力均勻分布，提高抗疲勞磨損的能力。在潤(rùn)滑油中加入極壓添加劑或固體潤(rùn)滑劑，能提高接觸表面的抗疲勞性能。③合理選擇零件接觸面的硬度。以軸承鋼為例，硬度為62HRc時(shí)，抗疲勞磨損能力較高，增加或降低表面硬度，壽命都有較大的降低。

In order to improve the fatigue life of the part surface, in addition to selecting friction pair materials reasonably, attention should also be paid to: ① selecting the surface roughness of the part contact surface reasonably. In general, the smaller the surface roughness value, the longer the fatigue life Reasonably select the viscosity of lubricating oil. Oil with low viscosity is prone to penetrate cracks and accelerate crack propagation. Lubricants with high viscosity are beneficial for uniform distribution of contact stress and improve their ability to resist fatigue wear. Adding extreme pressure additives or solid lubricants to lubricating oil can improve the fatigue resistance of contact surfaces Reasonably select the hardness of the contact surface of the parts. Taking bearing steel as an example, when the hardness is 62HRc, the resistance to fatigue wear is higher. Increasing or decreasing the surface hardness results in a significant decrease in lifespan.

4.中空玻璃生產(chǎn)線腐蝕磨損摩擦過(guò)程中，金屬與周圍介質(zhì)(如空氣中的酸、潤(rùn)滑油等)發(fā)生化學(xué)或電化學(xué)反應(yīng)而引起的表面損傷，稱為腐蝕磨損。其中氧化磨損常見(jiàn)，這是金屬摩擦副在氧化性介質(zhì)中工作時(shí)，接觸表面反復(fù)生成、磨去氧化膜的磨損現(xiàn)象，實(shí)際上是化學(xué)氧化和機(jī)械磨損兩種作用相繼進(jìn)行的過(guò)程。氧化磨損的大小取決于氧化膜的連接強(qiáng)度和氧化速度。

4. During the corrosion and wear friction process of insulating glass production lines, surface damage caused by chemical or electrochemical reactions between metals and surrounding media (such as acid and lubricating oil in the air) is called corrosion and wear. Among them, oxidative wear is common, which is a phenomenon of repeated generation and removal of oxide film on the contact surface of metal friction pairs when working in an oxidizing medium. In fact, it is a process in which chemical oxidation and mechanical wear occur successively. The magnitude of oxidative wear depends on the connection strength and oxidation rate of the oxide film.
