Welcome to inquire! Contact: Niu Yang. Some people think that, in dealing with the spherical ball tile and hollow shaft journal with the majority of small backlash good lead into the hollow shaft when the film is not easy to slag mill where to buy, or the occurrence of localized surface spherical bush burning, often manifested in oil not smoothly into spherical hollow shaft journal and a large tile mill slag contact area, many people believe is a spherical hollow shaft journal watt backlash is too small to fit slag mill, but does not necessarily, spherical hollow shaft tile neck tie backlash have more clearly defined in the national building materials industry standard JC 334.1-94 first 4.3.2.la, the mating backlash must form a more standardized wedge backlash small water mill slag, it helps to guide oil people, and approximately equal thickness or stepped backlash is not conducive to import oil, almost equal thickness big backlash has tile edges on both sides of the oil pouring into the tendency is not conducive to the formation of an oil film. Someone in the maintenance of the spherical ball mill watts, often to make some hollow shaft journal surface treatment, a common practice there, and the first with multi-strand rope twist on fine sandpaper, bypassing the hollow shaft journal circle, by two come with pull, then change back and forth with a multi-strand rope pulling on the hollow shaft journal polished, while others repeatedly polished with sandpaper hollow shaft journal, in fact, this practice is undesirable because it would be a hollow shaft journal loss of roundness, becoming edge structure is not conducive to the formation of the film, in fact, after a long-running hollow shaft journal, in addition to the outside due to the severe bush-burning in the hollow shaft bearing journal surface bonding alloy, hollow shaft journal Roundness is in the best condition, the so-called polishing treatment generally does not require a large area, even if severe when the bush-burning in the house shaft journal bearing alloy bonded, also only partial, the slight surface treatment they are not to destroy the hollow shaft journal roundness.
