At present, there is a large demand for self feeding mixers in the market, and many people buy them. Their manufacturing process is also very professional. How much do you know about the manufacturing process of the bearings of mixers?
The design and manufacturing process of the bearing of the mixer truck must take into account the thermal balance of the bearing to control the temperature rise. Because the bearing works under the friction state, the power consumption is caused by the internal friction of the lubricating liquid, which will cause the bearing temperature rise after being converted into heat, the viscosity of the lubricating oil will be reduced, the clearance will be changed, and the babbitt alloy of the bearing will be softened.
In serious cases, the accident of "burning the bearing and holding the shaft" will occur. The mixer truck will improve the maintenance and assembly quality of the bearing, ensure that the back of the bearing is smooth and free of spots, the locating bumps are intact, and the self spring opening is 0.5-1.5mm, which will ensure that the bearing bush will fit tightly with the bearing seat hole with its own elasticity after assembly.
Each end of the upper and lower bearing pads in the transfer bearing pedestal shall be 30-50 microns higher than the plane of the bearing pedestal, which can ensure that the bearing is closely matched with the bearing pedestal after the bolts of the bearing cover are tightened according to the specified torque to generate sufficient friction self-locking force, the bearing will not be loose, the heat dissipation effect is good, and the bearing ablation and wear are prevented. The working surface of the bearing cannot be measured by 75% - 85% contact mark with scraping method, The fit clearance between bearing and shaft diameter shall meet the requirements without scraping.
In addition to the maintenance of the engine, chassis and other parts of the mixer, the concrete mixing tank and the inlet and outlet must also be cleaned. After each delivery of concrete, the mixing tank and the inlet and outlet hopper must be cleaned in a timely manner, which can effectively reduce the phenomenon of concrete adhering to the tank, reduce the maintenance intensity of the vehicle, stagger the peak production, and timely repair welding of the feed hopper, discharge outlet and discharge chute, The tank body repair opening shall be added to reduce the slurry leakage and material leakage caused by the equipment during the feeding and discharging process, and to ensure the cleanliness of the equipment to a large extent on the basis of ensuring the equipment integrity rate.
The maintenance of the mixer is essential in the process of use. We should try our best to cover every aspect of the maintenance and do a good job in the maintenance of the mixer. More relevant content will come to our website https://www.zishangliaojiaobanji.cn Consult!
