减速机是搅拌车专用装置的重要组成部分，是原动机和工作机之间的独立的闭式传动装置。在长时间的工作过程中，搅拌车减速机难免会出现一些故障或损坏，下面就随小编来了解一下关于搅拌车减速机易损坏的部位内容吧。

The reducer is an important part of the special device of the mixer truck, and it is an independent closed transmission device between the prime mover and the working machine. In the process of long-time work, the mixer reducer will inevitably have some faults or damages. Let's follow the editor to learn about the parts of the mixer reducer that are easy to be damaged.

轴承

bearing

（1）部分滚动体承载过大。减速机在工作中，若轴承调心角度达到极限，会造成个别轴承滚动体承载急剧增大，导致滚动体与内、外圈相接触的位置发生塑性变形，甚至引起内、外圈断裂。

(1) Some rolling elements are overloaded. During the operation of the reducer, if the bearing centering angle reaches the limit, the bearing capacity of individual bearing rolling elements will increase sharply, resulting in plastic deformation at the contact position between the rolling elements and the inner and outer rings, and even fracture of the inner and outer rings.

（2）轴承定位失效。减速机在工作中，若轴承锁紧螺母在轴向冲击载荷作用下产生松脱，失去锁紧作用，将造成轴承承载状况恶化，导致轴承磨损加剧甚至损坏。

(2) Bearing positioning failure. During the operation of the reducer, if the lock nut of the bearing looses and loses its locking function under the axial impact load, the bearing bearing condition will deteriorate, resulting in increased wear and even damage to the bearing.

（3）轴承滚动面有异物。若减速机内部混入杂质，将导致轴承磨损加快，甚至损坏。等等。

(3) There are foreign matters on the rolling surface of the bearing. If impurities are mixed in the reducer, the bearing will be worn faster or even damaged. Wait.

齿轮齿圈

Gear ring gear

（1）齿根疲劳折断。轮齿长期承受交变载荷后，齿根处就会产生疲劳裂纹。该裂纹逐步扩展，直至轮齿疲劳折断。

(1) Tooth root fatigue fracture. Fatigue cracks will occur at the root of the gear tooth after it has been subjected to alternating load for a long time. The crack propagated gradually until the gear teeth were fatigued and broken.

（2）冲击载荷过大。若齿轮、齿圈突然受到过大的冲击载荷，可造成轮齿折断。

(2) Excessive impact load. If the gear and ring gear are suddenly subjected to excessive impact load, the gear teeth may be broken.

（3）润滑油不清洁。若润滑油不清洁，轮齿啮合面有磨料反复作用，将加速齿面磨损，导致齿轮、齿圈报废。

(3) The lubricating oil is not clean. If the lubricating oil is not clean, the tooth meshing surface will have abrasive repeated action, which will accelerate the wear of the tooth surface, resulting in the scrapping of the gear and ring gear.

壳体

housing

（1）载荷过大。若全自动搅拌车减速机壳体载荷过大，可造成其过早损坏，甚至还会对减速机内部结构件产生不利影响。

(1) Excessive load. If the load on the reducer housing of the full-automatic mixer is too large, it may cause premature damage, and even adversely affect the internal structural parts of the reducer.

（2）存在铸造缺陷。若减速机壳体存在铸造缺陷，在长期复合载荷作用下，壳体铸造缺陷处容易出现裂纹，导致壳体破裂。

(2) There are casting defects. If the reducer housing has casting defects, cracks are easy to appear at the casting defects of the housing under the action of long-term composite load, resulting in the cracking of the housing.

输出法兰

Output flange

（1）输出法兰存在制造缺陷。输出法兰在锻造时，若产生微小裂纹，在使用的过程中微小裂纹不断扩展，在输出法兰过载情况下便会导致突然断裂。

(1) The output flange has manufacturing defects. When the output flange is forged, if there is a small crack, the small crack will continue to expand in the process of use, which will lead to sudden fracture when the output flange is overloaded.

（2）严重超载。在搅拌车严重超载情况下，在运输过程中若发生路面颠簸，会造成输出法兰因承受过大的冲击载荷而断裂。

(2) Severe overload. When the mixer truck is seriously overloaded, if the road bumps during transportation, the output flange will be broken due to excessive impact load.

接合部位

Joint

（1）极限工况造成油封损坏。为了适应恶劣工况，全自动搅拌车减速机的输出法兰在实际工作中有个±4.5°摆角。在极限工况时，由于输出法兰摆角过大，将油封挤压变形，导致减速机漏油。

(1) The oil seal is damaged under extreme working conditions. In order to adapt to severe working conditions, the output flange of the reducer of the full-automatic mixer truck has a swing angle of ± 4.5 ° in actual work. Under extreme working conditions, the oil seal is extruded and deformed due to the excessive swing angle of the output flange, resulting in oil leakage of the reducer.

（2）减速机组装前，没有将前盖和主壳体接合面清理干净，或密封胶涂抹不均匀，致使密封胶起不到密封作用。在减速机工作过程中，主壳体承受冲击力产生变形，或前盖与主壳体连接螺栓松动，均会造成减速机漏油。

(2) Before the reducer is assembled, the joint surface between the front cover and the main housing is not cleaned, or the sealant is applied unevenly, which makes the sealant unable to seal. During the operation of the reducer, the main housing is deformed under impact force, or the connecting bolts between the front cover and the main housing are loose, which will cause oil leakage of the reducer.
