減速機是攪拌車(chē)專(zhuān)用裝置的重要組成部分，是原動(dòng)機和工作機之間的獨立的閉式傳動(dòng)裝置。在長(cháng)時(shí)間的工作過(guò)程中，攪拌車(chē)減速機難免會(huì )出現一些故障或損壞，下面就隨小編來(lái)了解一下關(guān)于攪拌車(chē)減速機易損壞的部位內容吧。

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.

軸承

bearing

（1）部分滾動(dòng)體承載過(guò)大。減速機在工作中，若軸承調心角度達到極限，會(huì )造成個(gè)別軸承滾動(dòng)體承載急劇增大，導致滾動(dòng)體與內、外圈相接觸的位置發(fā)生塑性變形，甚引起內、外圈斷裂。

(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）軸承定位失效。減速機在工作中，若軸承鎖緊螺母在軸向沖擊載荷作用下產(chǎn)生松脫，失去鎖緊作用，將造成軸承承載狀況惡化，導致軸承磨損加劇甚損壞。

(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）軸承滾動(dòng)面有異物。若減速機內部混入雜質(zhì)，將導致軸承磨損加快，甚損壞。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.

齒輪齒圈

Gear ring gear

（1）齒根疲勞折斷。輪齒長(cháng)期承受交變載荷后，齒根處就會(huì )產(chǎn)生疲勞裂紋。該裂紋逐步擴展，直輪齒疲勞折斷。

(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）沖擊載荷過(guò)大。若齒輪、齒圈突然受到過(guò)大的沖擊載荷，可造成輪齒折斷。

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

（3）潤滑油不清潔。若潤滑油不清潔，輪齒嚙合面有磨料反復作用，將加速齒面磨損，導致齒輪、齒圈報廢。

(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.

殼體

housing

（1）載荷過(guò)大。若全自動(dòng)攪拌車(chē)減速機殼體載荷過(guò)大，可造成其過(guò)早損壞，甚還會(huì )對減速機內部結構件產(chǎn)生不利影響。

(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）存在鑄造缺陷。若減速機殼體存在鑄造缺陷，在長(cháng)期復合載荷作用下，殼體鑄造缺陷處容易出現裂紋，導致殼體破裂。

(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.

輸出法蘭

Output flange

（1）輸出法蘭存在制造缺陷。輸出法蘭在鍛造時(shí)，若產(chǎn)生微小裂紋，在使用的過(guò)程中微小裂紋不斷擴展，在輸出法蘭過(guò)載情況下便會(huì )導致突然斷裂。

(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）嚴重超載。在攪拌車(chē)嚴重超載情況下，在運輸過(guò)程中若發(fā)生路面顛簸，會(huì )造成輸出法蘭因承受過(guò)大的沖擊載荷而斷裂。

(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）極限工況造成油封損壞。為了適應惡劣工況，全自動(dòng)攪拌車(chē)減速機的輸出法蘭在實(shí)際工作中有個(gè)±4.5°擺角。在極限工況時(shí)，由于輸出法蘭擺角過(guò)大，將油封擠壓變形，導致減速機漏油。

(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）減速機組裝前，沒(méi)有將前蓋和主殼體接合面清理干凈，或密封膠涂抹不均勻，致使密封膠起不到密封作用。在減速機工作過(guò)程中，主殼體承受沖擊力產(chǎn)生變形，或前蓋與主殼體連接螺栓松動(dòng)，均會(huì )造成減速機漏油。

(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.
