Presumably we all understand that different mechanical products, its assembly technology requirements are also different. If manufacturers want to ensure the assembly quality of stone machinery, they should operate in accordance with the prescribed assembly technical requirements. What are the technical requirements when assembling stone equipment? In order to help you solve the doubts, this is to introduce you.
Before assembling stone machinery, to clean the surface of the parts of the casting sand, rust, chips and other impurities, especially some important parts, such as gantry large cutting machine. After cleaning the parts, dry them with a compressed air machine. When assembling parts, the size should be determined. After the completion of matching, the parts should be rechecked or random checked, such as the matching position of spindle journal and bearing, spindle box and bearing hole and center distance. When assembling the gear closing wheel, the two axis lines are required to be in the same plane and parallel to each other, to ensure that there is a normal gear clearance, and the axial dislocation is less than 2MM. Check whether the joint surface of the bolt is smooth. If there is any abnormality, it should be trimmed in time to remove burrs and ensure that the contact is close and smooth. The sealing parts should be pressed into the sealing groove in parallel, and can not be distorted or damaged to scratch the sealing surface. When assembling the belt pulley, the two axes are required to be parallel, and the center of the wheel groove should be positive, otherwise the tension of the belt pulley will be uneven, resulting in belt slip and wear. Before bearing assembly, anti-rust paint should be washed off bearing surface. When cleaning, the raceway and rolling body should be checked for rust, whether the rotation is flexible, and then assembly is confirmed.
