滑动轴承的检验和调整中存在的问题和解决方法

1、滑动轴承的检验和调整中存在的问题和解决方法滑动轴承的检验和调整存在的问题the existing problems在安装过程中， 要注意调整滚动轴承的间隙。滚动轴承间隙分为径向间隙和横向间隙， 也就是两个套圈之间横向或者竖向的最大活动范围。间隙过大会导致整个轴承震动，从而降低旋转的精确度；间隙过小会加大两个套圈间的摩擦力，加剧设备磨损，降低使用寿命。During the installation process, should pay attention to adjust theclearance of rolling bearings. Divided into radial cleara

2、nce, rollingbearing clearance and horizontal interval, which is between the two ringthe largest scope of horizontal or vertical. Gap will cause the wholebearing vibration, thereby reducing the accuracy of the rotation; Startsto increase the friction between the two ring gap, increase equipmentwear a

3、nd tear, reduce the service life.滑动轴承的检验和调整解决方法 滑动轴承的检验和调整中存在的问题和解决方法对于径向间隙的调整， 需要根据机器运转情况和实际生产情况来决定。在高温、高速情况下，通常选择大的径向间隙；如果是精密主轴或者车床主轴，通常选择小的径向间隙。For radial clearance adjustment, need according to the machine runningsituation and the actual production situation to decide. Under thecondition of high

4、 temperature, high speed, usually choose big radialclearance; If its precision spindle or lathe spindle, usually choose smallradial clearance.滑动轴承的检验和调整The sliding bearing of the inspection and adjustment在滑动轴承的运转过程中， 对于轴承间隙过小、 过大和对于润滑剂浓度、灰尘量的监测，都有不同的方法，分别是在线温度监测、在线振动监测和定期铁谱分析。 而对于滑动轴承间隙的具体测量，又有以下三种方

5、法：压铅检查法、塞尺检查法和千分尺检查法。这三种方法各有特点，压铅检查法测量结果相对准确，但是比较费时费力；塞尺检查法主要用于轴颈间隙过大的轴承的检测；千分尺检查法的检测结果最为精准，操作方法也比较方便快捷。 滑动轴承的检验和调整中存在的问题和解决方法In the process of sliding bearing operation, for the bearing gap is toosmall, too, and for monitoring lubricant concentration, amount of dust,has a different approach, on-lin

6、e temperature monitoring, on-linevibration monitoring and iron spectrum analysis on a regular basis.Specific measurement for the sliding bearing clearance, and has thefollowing three methods: pressure lead test, feeler test and micrometermethod. These three methods have different characteristics and

7、 pressurelead test measurement result is relatively accurate, but are more time-consuming; Feeler gauge method is mainly used for journal largeclearance of bearing detection; Micrometer method of test results is mostaccurate, the operation method is more convenient and quick.3.轴承温度过高的检查与调整3. Check a

8、nd adjust the bearing temperature too high在设备运转中如果出现风机轴承温度过高的情况，通常有以下三种原因：润滑效果不好、冷却程度不够、轴承状况异常。If there is a fan in the equipment running bearing temperature is too high,usually has the following three reasons: the lubrication, cooling effect isbad enough, the condition of bearing 滑动轴承的检验和调整中存在的问题和解

9、决方法（1）离心式风机的检验和调整(1) the centrifugal fan of inspection and adjustment由于离心式风机轴承在风机的外面，所以一般通过目测或者听声就可以判断它在运转中产生问题的原因。对于由于润滑效果不好， 冷却程度不够产生的问题， 可以直接通过眼睛看、 手触摸的方式就能判断；如果是由于轴承过度作业产生磨损，出现间隙增大，麻坑、脱皮而引起的温度升高，通过听轴承的声音和测量振动情况就能判断。Due to the centrifugal fan bearing outside the fan, so usually by visual orhearin

10、g can judge it causes the problems in the operation. For because thelubrication effect is not good, the problem of cooling degree is not enough,can be directly through the eyes, hands touch can judge; If it is due to thebearing wear too much homework, a gap increases, hemp pit, peelingcaused by temp

11、erature, by listen to the voice of bearing and measuringvibration can judge that.（2）轴流风机的检验和调整(2) the inspection and adjustment of the axial flow 滑动轴承的检验和调整中存在的问题和解决方法由于轴流风机的轴承在轴承箱的里面，出现轴承温度过高的现象就无法通过上面介绍的方式来判断。我们在对其检验和调整过程中，可以从以下几个方面着手，判断轴承温度过高的原因或解决问题：Because of the axial flow fan bearing in the b

12、earing box, inside, thephenomenon of the high bearing temperature cannot be judged throughthe way described above. We are in the process of inspection andadjustment, can from the following several aspects, determine thecause of the bearing temperature is too high or solve the problem:加油操作是否规范。 加油一定要

13、按照厂家说明书规定操作。轴承加油后如果加油过多， 会使轴承温度升高； 但这种情况不会持续太久，温度升到一定值后又会逐渐下降。1) whether the refueling operation specification. Come on manualinstructions must be in accordance with the manufacturer. After bearingoil if the oil too much, can make the bearing temperature rise; But thiskind of situation will not last

14、 long, the temperature rises to a certain valuewill gradually decline.冷却风机冷却风量是否不足。引风机附近的烟温可以达到 滑动轴承的检验和调整中存在的问题和解决方法摄氏度以上，如果轴承箱没有有效冷却，轴承温度会升高。(2) the cooling fan, cooling air flow is insufficient. Induced draft fan nearsmoke temperature can reach 100 degrees Celsius above, if there is noeffective c

15、ooling bearing housing and bearing temperature rise.如果排除了以上两种情况， 轴承温度仍然过高， 就需要检查轴承箱。If you exclude the above two situations, bearing temperature is still toohigh, you need to check the bearing housing.建筑机械设备的维护与管理Second, construction machinery equipment maintenance and management要想提高建筑机械设备的使用效率，延长使用

16、寿命， 仅仅是提高安装质量和维修技术是不够的，同时要提高维修人员的素质，加强维修养护管理。Wants to raise the use efficiencyofconstruction machinery andequipment, prolong service life, simply is not enough to improve 滑动轴承的检验和调整中存在的问题和解决方法quality of installation and maintenance technology, to improve the qualityof the maintenance personnel at th

17、e same time, strengthen themaintenance and maintenance management.定期对设备进行保养与维修(a) on a regular basis for maintenance and repair equipment在建筑工程中， 机械设备应该定期进行保养和维修。将保养与维修工作做在出现故障和事故的前面，而不是等出现了事故或者故障才紧急抢修。将一些小问题和故障消灭在萌芽之中。在日常生产施工中，对于主要设备应该有专人定时对设备运转情况进行巡检，及时发现问题，解决问题。对于一些在生产过程中无法解决的问题，要在节假日集中解决，切不可拖沓应付，

18、将小毛病拖成大问题。In construction engineering, machinery and equipment should be regularlymaintenance and repair. The maintenance and repair work to do in theevent of a failure and accident in front of, rather than waiting for theaccident or failure to emergency repairs. Will be a few small problems andfault elimination in the bud. In daily production and construction, for mainequipment there sh
