搅拌机的驱动桥输出扭矩大,结构复杂,容易出现故障。下面我们将介绍常见故障的原因、现象及处理方法。
The drive axle of the mixer has large output torque and complex structure, which is prone to failure. Next, we will introduce the causes, phenomena and treatment methods of common faults.
1、声音异常。
1. Abnormal sound.
驱动桥发出声音的原因比较复杂。如果零件质量不达标,主传动总成调整不当,磨损过大,装载机工作时会发出噪音。
The reasons for the sound of the drive axle are complex. If the quality of parts is not up to standard, the main drive assembly is improperly adjusted, and the wear is too large, the loader will make noise when working.
(1)齿轮啮合间隙不当引起的声音。例如啮合间隙过大的牙齿相互碰撞,发出有节奏的“咯咯、咯咯”声;如果啮合间隙过小,牙齿相互挤压,声音为连续的“咳”声,并伴有发热;当啮合间隙不均匀时,声音为有节奏的“硬”声,严重时驱动桥会摆动。处理方法是拆下主传动机构,重新调整齿轮的啮合间隙。
(1) Sound caused by improper gear meshing clearance. For example, teeth with too large meshing gap collide with each other, making a rhythmic "cluck, cluck" sound; If the meshing gap is too small, the teeth squeeze each other, and the sound is a continuous "cough" sound, accompanied by fever; When the meshing clearance is uneven, the sound is a rhythmic "hard" sound, and the drive axle will swing in serious cases. The treatment method is to dismantle the main transmission mechanism and readjust the meshing clearance of the gears.
(2)轴承间隙不当的声音。若轴承游隙过小,则发出“响……”的连续声;轴承游隙过大时,会发出凌乱的“哈啦,哈啦”声。方法是拆下主传动机构,重新调整轴承游隙。
(2) Sound of improper bearing clearance. If the bearing clearance is too small, a continuous sound of "ring..." will be emitted; When the bearing clearance is too large, it will make a messy "ha, ha" sound. The solution is to remove the main transmission mechanism and readjust the bearing clearance.

(3)差速器异响:如行星齿轮与十字轴卡死时,会出现“嘎嘎、嘎嘎”的声音,多发生在转弯时;行星齿轮啮合不良的声音比较复杂,机器在直线行驶时是“嗯……”的声音,机器转速越高,声音越大,还会有转动时发出“咔嚓”声。处理方法是拆下主传动机构,更换十字轴或行星齿轮。
(3) Differential abnormal noise: if the planetary gear and cross shaft are stuck, there will be a "quack, quack" sound, which mostly occurs when turning; The sound of poor meshing of planetary gears is more complex. When the machine runs in a straight line, it is the sound of "hum...". The higher the speed of the machine, the louder the sound is, and there will be a "click" sound when it rotates. The treatment method is to remove the main transmission mechanism and replace the spider or planetary gear.
2.过热。
2. Overheating.
例如,机器运转或工作一段时间后,如果触摸桥壳,如果感觉很热,则说明驱动桥过热。主要原因是轴承游隙和齿轮啮合游隙太小,缺少润滑油。处理方法是先检查是否缺少润滑油。如不缺油,应拆下主传动,检查调整轴承间隙或齿轮啮合间隙。
For example, if you touch the axle housing after the machine is running or working for a period of time, if it feels very hot, it means that the drive axle is overheated. The main reason is that the bearing clearance and gear meshing clearance are too small and lack of lubricating oil. The treatment method is to check whether there is a lack of lubricating oil first. If there is no lack of oil, remove the main drive, check and adjust the bearing clearance or gear meshing clearance.
3.漏油。
3. Oil leakage.
漏油现象是自动混凝土搅拌机在运转或停车时,在主传动与桥壳的接合处以及轮毂减速器内侧有齿轮油渗出。主传动与桥壳连接处漏油是由于螺栓松动或石棉纸垫片损坏;轮毂减速器内部漏油主要是双口骨架油封或“O”形密封圈损坏。处理方法是更换双唇骨架油封或石棉纸垫。
The phenomenon of oil leakage is that when the automatic concrete mixer is running or stopped, there is gear oil seepage at the joint between the main drive and the axle housing and the inner side of the hub reducer. The oil leakage at the connection between the main drive and the axle housing is due to loose bolts or damaged asbestos paper gaskets; The oil leakage inside the hub reducer is mainly caused by the damage of the double port skeleton oil seal or "O" ring. The treatment method is to replace the double lip framework oil seal or asbestos paper pad.
