In the design and manufacturing process of mixer truck bearing, the thermal balance of bearing should be considered to control the temperature rise. Because the bearing works under the friction state, the power consumption is caused by the internal friction of lubricating liquid, which will cause the bearing temperature rise after being converted into heat. The viscosity of lubricating oil will be reduced and the clearance will be changed, which will soften the Babbitt alloy of bearing, and even cause the accident of "Bush burning and axle holding", The automatic mixer improves the maintenance and assembly quality of the bearing, ensures that the back of the bearing is smooth without spots, the positioning bump is intact, and its own spring opening is 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(zhuǎn)載軸承座內(nèi)的上下兩片軸瓦的每端均應(yīng)高出軸承座平面30-50微米，高出量可保證按規(guī)定扭矩?cái)Q緊軸承蓋螺栓后軸承與軸承座緊密配合，產(chǎn)生足夠的摩擦自鎖力，軸承不致松動(dòng)，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(dá)到75%-85%接觸印痕做衡量標(biāo)準(zhǔn)，應(yīng)在不刮削時(shí)就使軸承和軸徑的配合間隙達(dá)到要求。

This ensures that after assembly, the bearing bush fits closely with the bearing seat hole with the help of its own elastic force. Each end of the upper and lower bearing bush in the transfer bearing seat should be 30-50 microns higher than the bearing seat plane. The higher amount can ensure that after the bearing cover bolts are tightened according to the specified torque, the bearing and the bearing seat are closely matched to produce enough friction self-locking force, the bearing will not be loose, and the heat dissipation effect is good, In order to prevent bearing ablation and wear, the working surface of bearing can not be measured by scraping method to achieve 75% - 85% contact marks, and the clearance between bearing and shaft diameter should meet the requirements without scraping.

攪拌車的使用除了對(duì)發(fā)動(dòng)機(jī)、底盤等部位進(jìn)行維護(hù)外，還做好對(duì)混凝土攪拌罐及進(jìn)出料口的清洗，在每次運(yùn)送混凝土結(jié)束后，要及時(shí)的清洗攪拌罐及進(jìn)出料斗。

In addition to maintaining the engine, chassis and other parts, the mixer should also clean the concrete mixing tank and the inlet and outlet. After each delivery of concrete, the mixing tank and the inlet and outlet hopper should be cleaned in time.

這樣可有用減少混凝土粘附罐體的現(xiàn)象，可降低車輛的保養(yǎng)工作強(qiáng)度，錯(cuò)開生產(chǎn)高峰，及時(shí)的對(duì)進(jìn)料斗、下料口及卸料槽進(jìn)行局部的補(bǔ)焊，加裝罐體修止口，以減少設(shè)備在進(jìn)出料過程中造成的漏漿漏料現(xiàn)象，在保證設(shè)備完好率的基礎(chǔ)上大限度的保證設(shè)備的整潔。

This can effectively reduce the phenomenon of concrete adhering to the tank, reduce the maintenance intensity of vehicles, stagger the production peak, timely carry out local repair welding on the feed hopper, discharge port and discharge tank, and install tank repair port, so as to reduce the slurry leakage phenomenon caused by the equipment in the process of material import and export, and ensure the cleanliness of the equipment to a large extent on the basis of ensuring the integrity rate of the equipment.

自動(dòng)攪拌車在使用過程中保養(yǎng)是必不可少的，大家在做保養(yǎng)的時(shí)候盡量能夠面面俱到，將攪拌車的保養(yǎng)做到好。

Automatic mixer in the use of the process of maintenance is essential, we try to be able to do all aspects of the maintenance, the maintenance of the mixer well.
