混凝土搅拌车滑动轴承损坏怎么办?实际上该搅拌车滑动轴承的早期损坏比轴承烧坏更常见,因此防止滑动轴承的早期损坏非常重要。
What to do if the sliding bearing of the concrete mixer is damaged? In fact, the early damage of the sliding bearing of the mixer is more common than the burning out of the bearing, so it is very important to prevent the early damage of the sliding bearing.
在气缸压力冲击载荷的反复作用下,滑动轴承表层发生塑性变形和冷加工硬化,部分丧失变形能力,逐渐形成条纹并膨胀,然后随着磨屑的脱落,在受力表层形成空洞。
Under the repeated action of cylinder pressure impact load, plastic deformation and cold work hardening will occur on the surface of sliding bearing, which will partially lose the deformation ability, gradually form stripes and expand, and then form cavities on the stressed surface with the falling off of wear debris.
一般情况下,轴瓦发生点蚀时,点蚀首先出现,然后点蚀逐渐扩大,导致合金层的界面开裂。裂纹沿界面平行方向扩展,直至剥离。
In general, when pitting occurs on the bearing bush, the pitting first appears, and then gradually expands, resulting in interface cracking of the alloy layer. The crack propagates parallel to the interface until it peels off.
滑动轴承空蚀的主要原因是油槽、油孔等结构元件截面的突变导致油流的强烈无序,在无序的真空区形成气泡,然后由于压力升高导致气泡坍塌而发生空蚀。
The main reason for the cavitation of sliding bearings is that the abrupt change of the cross-section of structural elements such as oil grooves and oil holes leads to the strong disorder of oil flow, forming bubbles in the disordered vacuum area, and then collapsing bubbles due to the pressure rise to cause cavitation erosion.
气蚀通常发生在轴承的高负荷区域,如曲轴主轴承的下轴瓦。轴承外圈是轴承在座孔内的相对转动。轴承通过外圈后,不仅影响轴承的散热,容易造成轴承内表面的合金腐蚀,而且会损坏轴承的背面,严重时会烧坏轴承。主要原因是轴承太短,榫头损坏,加工或安装不符合规范。
Cavitation usually occurs in the high load area of the bearing, such as the lower bearing bush of the crankshaft main bearing. The bearing outer ring is the relative rotation of the bearing in the seat hole. After the bearing passes through the outer ring, it will not only affect the heat dissipation of the bearing, but also easily cause alloy corrosion on the inner surface of the bearing, and damage the back surface of the bearing. In serious cases, it will burn the bearing. The main reasons are that the bearing is too short, the tenon is damaged, and the processing or installation does not meet the specifications.
滑动轴承的正确维护是减少轴承早期损坏的有效途径,也是延长轴承使用寿命的可靠保证。因此,在发动机的日常保养和维修中,一定要注意合金表面、轴承背面、端部和棱角的外观形状。
The correct maintenance of sliding bearings is an effective way to reduce the early damage of bearings and also a reliable guarantee to prolong the service life of bearings. Therefore, in the daily maintenance and repair of the engine, attention must be paid to the appearance and shape of the alloy surface, bearing back surface, end and corner.
如果有异常迹象或磨损过半,一定要认真查找原因,采取相应措施,改善轴承的工作条件,注意防止滑动轴承的早期损坏。更多事项了解,关注我们网站http://www-zkzdsljbc-com.irwinroth.com吧!
If there are abnormal signs or half wear, it is necessary to carefully find out the cause, take corresponding measures, improve the working conditions of the bearing, and pay attention to preventing early damage of the sliding bearing.
