Bearing: the fan bearing the main reason for the lack of oil, holding in death

Axis of the ship under various load is actually a line rather than a straight line, if the ship design in the light of blade margin is not very rich, the propeller is lay particular stress on, the popular known as the 'heavy oar heypropeller'. Before use, first remove the plate to glue roller level into pull out a few times, as soon as the ink dot size on the glue roller, the operator according to the different needs of print to determine the degree of printing rubber roller, and then put the top wire rope. The material has good cohesive force, compressive properties and have metal comprehensive mechanics performance of elastic deformation and so on to realize online repair, repair of high efficiency, short time to repair. When there is a relative motion between two objects in contact, will produce a surface damage, if the damage to continue to proceed, it will cause erosion, is the wear and tear. It is not recommended for forging steel, use should be careful when installing: do not allow the powerful punch, are not allowed to use hammer percussion bearing directly, don't allow through the transfer roller pressure. Other factors to consider the influence of bearing installation and dismantling convenient, appropriate USES loose fit, with large or super large bearings for heavy machinery is particularly important. This time you should have confidence in their calculation, the solution: use special tooling, make the bearing inner ring or outer ring uniform compression in the process of assembly, assembly in place. Eight, oil mist lubrication with dry compressed air after the sprayer and lubricating oil mixed form oil mist, spray import motor bearing, can effectively make the bearing cooling airflow and prevents impurities. Anticorrosive processing, assembly before the bearing in the bearing interior coating material of SDH again, let the bearing outer ring and bearing chamber interface is greater than %, and tighten up and down quickly bearing chamber. Due to the bearing inner cavity size is different, so it is difficult to determine how much oil, it is important to protect with grease in the bearing, if excess oil, when bearing rotation, excess oil will seep. In order to solve the main bearing instead of ball bearing limit speed after fever, noise problem, can use light series column bearing, outside and put it on the fan, cooling condition is good, at the same time bearing noise can also be swallowed up by the fan noise. How to diagnosis of rolling bearing is damaged and can continue to use, rolling bearing assembly of rolling bearing assembly correctly, there are mainly two key problems, is bearing cleaning method, is bearing installation method.
