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.

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。

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.

搅拌车的使用除了对发动机、底盘等部位进行维护外，还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。

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.

这样可有用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大限度的保证设备的整洁。

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.

自动搅拌车在使用过程中保养是必不可少的，大家在做保养的时候尽量能够面面俱到，将搅拌车的保养做到好。

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.
