搅拌车轴承的设计和制作工艺，必须要考虑到轴承的热平衡以控制温升，因为轴承在摩擦状态下工作，由于润滑液体内部摩擦而造成功耗，转化成热量后引起轴承温升，润滑油粘度降低、间隙会改变，会使轴承的巴氏合金软化，严重时产生“烧瓦抱轴”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..

搅拌车提高轴承的维修和装配质量，保证轴承背面光滑点，定位凸点完整无损，自身的弹开量为0.5-1.5mm，这保证装配后轴瓦借助自身弹力与轴承座孔贴合紧密，转载轴承座内的上下两片轴瓦的每端均应高出轴承座平面30-50微米，高出量可保证按规定扭矩拧紧轴承盖螺栓后轴承与轴承座紧密配合，产生足够的摩擦自锁力，轴承不致松动，散热效果好，防止轴承烧蚀和磨损，轴承的工作面不能用刮配法达到75%-85%接触印痕做衡量标准，应在不刮削时就使轴承和轴径的配合间隙达到要求。

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.

搅拌车的使用除了对发动机、底盘等部位进行维护外，还必须做好对混凝土搅拌罐及进出料口的清洗，在每次运送混凝土结束后，要及时的清洗搅拌罐及进出料斗，这样可有效减少混凝土粘附罐体的现象，可降低车辆的保养工作强度，错开生产高峰，及时的对进料斗、下料口及卸料槽进行局部的补焊，加装罐体修止口，以减少设备在进出料过程中造成的漏浆漏料现象，在保证设备完好率的基础上限度的保证设备的整洁。

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.
