中空玻璃生产线的磨损主要有哪些问题?

1.中空玻璃生产线粘着磨损,在切向力的作用下,摩擦副表面的吸附膜和服污膜遭到破坏,使表面的轮廓峰在相互作用的各点处发生冷焊,由于相对运动,材料便从一个表面转移到另一个表面,形成粘着磨损。在此过程中,有时材料也会再次附着回原表面,出现逆转移,或脱离所粘附的表面而成为游离颗粒。载荷越大,表面温度越高,粘着的现象也越严重。严重的粘着磨损会造成运动副咬死。粘着磨损是金属摩擦副之间最普遍的一种磨损形式。
1. the insulating glass production line is adhered to wear. Under the action of tangential force, the adsorption film and the coating film of the surface of the friction pair are destroyed, so that the contour peak of the surface is welded by cold welding at each point of interaction. As a result of relative motion, the material is transferred from one surface to another, forming adhesive wear. In this process, sometimes the material will be attached back to the original surface again, resulting in an inverse transfer or dissociation from the adherent surface and become a free particle. The larger the load is, the higher the surface temperature is, the more serious the adhesion phenomenon is. Severe adhesive wear will result in the death of the pair. Adhesive wear is the most common form of wear among metal friction pairs.
为了减轻粘着磨损,可采取以下措施:①合理选择配对材料。同种金属比异种金属易于粘着;脆性材料比塑性材料的抗粘着能力强。进行表面处理(如表面热处理、电镀、喷涂等)可防止粘着磨损的发生。②限制摩擦表面的温度。⑤采用含油性和极压添加剂的润滑剂。④控制压强。
In order to reduce adhesive wear, the following measures can be taken: 1. The same metals are easier to adhere than dissimilar metals; brittle materials are more resistant to adhesion than plastic materials. Surface treatment (such as surface heat treatment, electroplating, spraying, etc.) can prevent adhesion wear. 2. Limit the temperature of the friction surface. Lubricants containing oil-bearing and extreme pressure additives. (4) control the pressure.

2.中空玻璃生产线磨粒磨损从外部进入摩棕面间的游离硬质颗粒(如尘土或磨损造成的金属微粒)或硬的轮廓峰尖,在较软材料表面犁刨出很多沟纹而引起材料脱落的现象,称为磨粒磨损。磨粒磨损与摩擦副材料的硬度和磨粒的硬度有关。有时选用较便宜的材料,定期更换易磨损的零件,更符合经济原则。

2. hollow glass production line abrasive wear from the outside into the surface of the friction between the free hard particles (such as dust or wear caused by metal particles) or hard contour peak point, plow a lot of furrow on the soft material surface plow a lot of furrow and cause material loss, called abrasive wear. The abrasive wear is related to the hardness of the friction pairs and the hardness of the abrasive particles. Sometimes cheaper materials are used to replace worn parts regularly, which is more in line with economic principles.
3.中空玻璃生产线疲劳磨损,在变接触应力的作用下,如果该应力超过材料相应的接触疲劳极限,就会在摩擦副表面或表面以下一定深度处形成疲劳裂纹,随着裂纹的扩展及相互连接,金属微粒便会从零件工作表面上脱落,导致表面出现麻点状损伤现象.即形成疲劳磨损或称疲劳点蚀。
3. the fatigue wear of the insulating glass production line, under the action of variable contact stress, if the stress exceeds the corresponding contact fatigue limit of the material, the fatigue crack will be formed at a certain depth below the surface of the friction pair or below the surface. With the expansion and connection of the cracks, the metal particles will fall off the working surface of the parts, leading to the loss of the metal particles. The phenomenon of pitting damage appears on the surface, that is, fatigue wear or fatigue pitting.
为了提高零件表面的疲劳寿命,除应合理选择摩擦副材料外,还应注意:①合理选择零件接触面的表面租糙度。一般情况下表面粗糙度值越小,疲劳寿命越长。②合理选择润滑油粘度。粘度低的油易渗人裂纹,加速裂纹扩展。粘度高的润滑油有利于接触应力均匀分布,提高抗疲劳磨损的能力。在润滑油中加入极压添加剂或固体润滑剂,能提高接触表面的抗疲劳性能。③合理选择零件接触面的硬度。以轴承钢为例,硬度为62HRc时,抗疲劳磨损能力最高,增加或降低表面硬度,寿命都有较大的降低。
In order to improve the fatigue life of parts, we should also pay attention to the following aspects: (1) choose the surface roughness of the surface of parts reasonably. In general, the smaller the surface roughness is, the longer the fatigue life is. 2. Choose the viscosity of the lubricating oil reasonably. Low viscosity oil can permeate human cracks and accelerate crack propagation. High viscosity lubricants are conducive to uniform distribution of contact stress and improve the ability to resist fatigue and wear. Adding extreme pressure additives or solid lubricants in lubricating oil can improve the fatigue resistance of contact surfaces. (3) to choose the hardness of the contact surface of the parts reasonably. Taking bearing steel as an example, when the hardness is 62HRc, the fatigue wear resistance is the highest, and the surface hardness and life of the bearing steel are greatly reduced.
4.中空玻璃生产线腐蚀磨损摩擦过程中,金属与周围介质(如空气中的酸、润滑油等)发生化学或电化学反应而引起的表面损伤,称为腐蚀磨损。其中氧化磨损最为常见,这是金属摩擦副在氧化性介质中工作时,接触表面反复生成、磨去氧化膜的磨损现象,实际上是化学氧化和机械磨损两种作用相继进行的过程。氧化磨损的大小取决于氧化膜的连接强度和氧化速度。
4. the surface damage caused by chemical or electrochemical reaction between metal and the surrounding medium (such as acid and lubricating oil in air, etc.) is called corrosion wear during the corrosion and wear friction process of the insulating glass production line. It is the most common oxidation wear, which is the phenomenon of repeated formation of the contact surface and wear out of the oxide film when the metal friction pair works in the oxidizing medium. In fact, it is a process of two kinds of action, chemical oxidation and mechanical wear. The magnitude of oxidation wear depends on the bonding strength and oxidation rate of the oxide film.
