混凝土攪拌車輪胎偏磨怎么？

攪拌車軸承的設計和制作工藝，必須要考慮到軸承的熱平衡以控制溫升，因為軸承在摩擦狀態下工作，由于潤滑液體內部摩擦而造成功耗，轉化成熱量后引起軸承溫升，潤滑油粘度降低、間隙會改變，會使軸承的巴氏合金軟化，嚴重時產生“燒瓦抱軸”的事故。。

In the design and manufacturing process of mixer bearing, the thermal balance of bearing must be considered to control the temperature rise. Because the bearing works under the friction state, the internal friction of lubricating fluid will cause power consumption, and the temperature rise of bearing will be caused after it is converted into heat. The viscosity of lubricating oil will be reduced and the gap will be changed, which will soften the Babbitt alloy of bearing and cause the accident of "burning bush and holding shaft" in serious cases..

攪拌車提高軸承的維修和裝配質量，保證軸承背面光滑點，定位凸點完整無損，自身的彈開量為0.5-1.5mm，這保證裝配后軸瓦借助自身彈力與軸承座孔貼合緊密，轉載軸承座內的上下兩片軸瓦的每端均應高出軸承座平面30-50微米，高出量可保證按規定扭矩擰緊軸承蓋螺栓后軸承與軸承座緊密配合，產生足夠的摩擦自鎖力，軸承不致松動，散熱效果好，防止軸承燒蝕和磨損，軸承的工作面不能用刮配法達到75%-85%接觸印痕做衡量標準，應在不刮削時就使軸承和軸徑的配合間隙達到要求。

The mixer improves the maintenance and assembly quality of the bearing, ensures that the back surface of the bearing is smooth without spots, the positioning bump is intact, and its own spring out amount is 0.5-1.5mm, which ensures that the bearing bush fits closely with the bearing seat hole with its own elastic force after assembly. Each end of the upper and lower bearing shells in the transfer bearing seat should be 30-50 microns higher than the bearing seat plane, and the higher amount can ensure that the shaft is tightened according to the specified torque After the bearing cover bolts, the bearing and the bearing seat are closely matched to produce sufficient friction self-locking force. The bearing will not be loose and the heat dissipation effect is good, so as to prevent the bearing from ablation and wear. The working surface of the bearing can not reach 75% - 85% contact mark by scraping method. The fit clearance between bearing and shaft diameter should meet the requirements without scraping.

攪拌車的使用除了對發動機、底盤等部位進行維護外，還必須做好對混凝土攪拌罐及進出料口的清洗，在每次運送混凝土結束后，要及時的清洗攪拌罐及進出料斗，這樣可有效減少混凝土粘附罐體的現象，可降低車輛的保養工作強度，錯開生產高峰，及時的對進料斗、下料口及卸料槽進行局部的補焊，加裝罐體修止口，以減少設備在進出料過程中造成的漏漿漏料現象，在保證設備完好率的基礎上限度的保證設備的整潔。

In addition to the maintenance of the engine and chassis, the mixing tank and the inlet and outlet of the concrete mixing tank must be cleaned well. After each delivery of concrete, the mixing tank and inlet and outlet hopper should be cleaned in time. This can effectively reduce the phenomenon of concrete adhering to the tank body, reduce the maintenance intensity of the vehicle, stagger the production peak and timely feed The bucket, discharge port and discharge tank shall be repaired locally, and the tank body repair mouth shall be installed to reduce the slurry leakage and material leakage caused by the equipment in the process of material import and export, and ensure the equipment cleanliness to the maximum extent on the basis of ensuring the intact rate of the equipment.
