根据挖掘机异响出现时机与特征做出诊断

日期:2022-12-02   来源:http://www.dybocheng.com
诊断时,应根据加长臂挖掘机异响出现的时机和特征,加长臂挖掘机租赁人员结合有关分析的原因进行排除。
During diagnosis, the leasing personnel of the extended boom excavator shall eliminate the abnormal sound according to the time and characteristics of the abnormal sound of the extended boom excavator and the relevant analysis.
(1)路试挖掘机直线行驶时出现异响,故障一般在主减速器或差速器轴承等处;转弯时出现异响,故障多数在差速器。
(1) The road test excavator makes abnormal noise when driving in a straight line, and the fault is usually at the main reducer or differential bearing; There is an abnormal noise when turning, and most of the faults are in the differential.
①如果响声高(尖叫),且是新装配,用手模驱动桥壳的差速部位有烫手难忍感,表明多数是由于装配过紧,各配合间隙过小所所致。
① If the noise is high (squeal) and it is a new assembly, the differential part of the hand model drive axle housing is too hot to bear, which indicates that most of the problems are caused by tight assembly and too small fit clearance.
②如果使用过久后出现响声,一般多数是由于各部机件磨损过甚使配合间隙过大所致。常表现为起步或车速发生变化时还会出现“咯噔”的响声。如果听到是干摩擦声,多数是由于驱动桥内润滑不良所致。
② If the noise occurs after being used for a long time, it is generally caused by excessive wear of various parts and even excessive fit clearance. It is often manifested as "clucking" noise when starting or when the vehicle speed changes. If the sound is dry friction, it is mostly caused by poor lubrication in the drive axle.
(2)停车检查检查时可靠手感或游隙测量仪进行。
(2) The parking inspection shall be carried out by hand feeling or clearance measuring instrument.
①用游隙测量仪检查驱动桥传动总间隙,其方法是:将变速器操纵杆置于空挡位置,松开驻车制动,将车轮制动,把游隙测量仪的刻度固定在减速器壳上,指针固定在传动轴的连接凸缘上。
① Check the total transmission clearance of the drive axle with the clearance measuring instrument by placing the transmission control lever at the neutral position, releasing the parking brake, braking the wheels, fixing the scale of the clearance measuring instrument on the reducer housing, and fixing the pointer on the connecting flange of the transmission shaft.

转动传动轴,使传动轴从一个极限位置转至另一个极限位置,测得其夹角值就是驱动桥传动总角间隙,即主减速器齿轮啮合间隙、差速器齿轮啮合间隙、半轴与半轴齿轮的配合间隙,以及轮边减速器齿轮的啮合间隙等总和,一般应在65℃左右,如果所测得角度过大,便表明驱动桥异响是因其传动机件间隙过大所致。
Rotate the transmission shaft to turn the transmission shaft from one extreme position to another. The measured included angle value is the total angular clearance of the drive axle, that is, the sum of the final reducer gear engagement clearance, the differential gear engagement clearance, the fit clearance between the half shaft and the half shaft gear, and the gear engagement clearance of the wheel side reducer. Generally, it should be about 65 ℃. If the measured angle is too large, It indicates that the abnormal noise of the drive axle is caused by the excessive clearance of its transmission parts.
②检查润滑情况卸下油平面螺塞,检查油平面高度。若过分缺油或油液变质,便说明异响是由润滑不良引起的。
② Check the lubrication condition, remove the oil level plug and check the oil level height. If there is too little oil or the oil deteriorates, it means that the abnormal noise is caused by poor lubrication.
③检查温度行驶时听到驱动桥有音调较高的响声时,可用手触摸驱动桥主减速器壳、差速器壳、轮边减速器壳的温度。如果有过热现象说明装配过紧,一般这种现象出现在新的或维修后的驱动桥。
③ Check the temperature. When you hear a high pitch sound from the drive axle when driving, you can touch the temperature of the drive axle final drive housing, differential housing and wheel reducer housing. If there is overheating, it indicates that the assembly is too tight. Generally, this phenomenon occurs on a new or repaired drive axle.
如果确诊异常响故障时,应解体检查,并对症排除。更多相关内容就来我们网站http://www.dybocheng.com进行咨询吧!
