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普遍的一种磨损形式。
1. Adhesive wear occurs in the production line of insulated 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 transfers from one surface to another, forming adhesive wear. During this process, sometimes the material may reattach to the original surface, resulting in reverse transfer or detachment from the adhered surface and becoming 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.
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。
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 adhesive 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 Using lubricants with oily and extreme pressure additives. ④ Control 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. The phenomenon of material detachment caused by abrasive wear on the surface of softer materials, where free hard particles (such as dust or metal particles caused by wear) or hard contour peaks enter between the frosted surfaces from the outside of the insulating glass production line. The 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. 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 friction pair surface 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 known as 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粗糙度。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。粘度低的油易渗入裂纹,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,抗疲劳磨损能力较高,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 the part surface, in addition to selecting friction pair materials reasonably, attention should also be paid to: ① Reasonably selecting the surface roughness of the part contact surface. In general, the smaller the surface roughness value, the longer the fatigue life Reasonably choose the viscosity of lubricating oil. Oil with low viscosity is prone to penetrate cracks and accelerate crack propagation. Lubricating oil with high viscosity is conducive to uniform distribution of contact stress and improves the ability to resist fatigue wear. Adding extreme pressure additives or solid lubricants to lubricating oil can improve the fatigue resistance of the contact surface Reasonably select the hardness of the contact surface of the parts. Taking bearing steel as an example, when the hardness is 62HRc, the fatigue wear resistance is higher. Increasing or decreasing the surface hardness results in a significant decrease in the service life.
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. During the corrosion and 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, oxidation 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 oxidizing media. In fact, it is a process of chemical oxidation and mechanical wear that occur successively. The magnitude of oxidative wear depends on the connection strength and oxidation rate of the oxide film.
