What belongs to the bearing material: bearing test technology

High vacuum, spacecraft, and semiconductor manufacturing equipment of medium speed bearings, such as: vacuum pump rotor bearing, vacuum coating equipment, vacuum valves, vacuum furnace, vacuum drying equipment, true outfit, vacuum unit electric fan bearing lubrication etc parts. According to the thickener can be divided into two categories, soap base grease and the soap base grease, such as industrial vaseline, etc. There are a few specifically for sealing grease, known as the sealing grease, such as thread compound. When the oil level in oil the scribed line, the actual measurement, bearing the low row ball has just come into contact with the oil level, only when the oil level is shown in the calibration on line, to meet the needs of the operation. Core parts of car is the engine is known to all the things, instead of rolling bearing? Below small make up together and discuss this problem! In the first place. According to understand, tell everyone in the process of using imported bearing, when it needs to be replaced a new bearing? Can be seen from the following points: mainly imported bearing inner ring and outer ring, rolling element and cage have crack or gap on any one; Imported bearing raceway surface, guard, with significant roller card injury; Imported bearing cage wear significantly, or rivet significant relaxation; Imported bearing ring, rolling body any fracture; Import on the raceway surface, rolling element bearing has serious indentation and mark; Imported bearing inner ring diameter or outer diameter surface has obvious creep; Imported bearing raceway surface, there are rust on rolling element and injury; Due to thermal change is obvious. Have higher request for pressure ball machine pressure type coal pressure ball machine equipment, the load is on the high side, using spherical roller bearing is suitable, both the heart function, and can bear larger load, but the price will be higher than plate bearing on much better. Baffles are used to prevent shaft oil by the journal after the back-end overflow, the truck has some use of cylindrical roller bearing axle box removal equipment, new truck mainly adopts sealed taper roller bearing axle box device. Stimulate the noise generated by the periodic force of rotating machinery, stimulate the noise will be the existence of the gap, the structure rigidity is not enough as part or serious friction increases, to shield Ann personnel on-site safety education, the generator bearing removal work completed, will be removed after all the oil on the bearing retainer is wiped clean. In our long-term operation of wood crusher in the process of production operation, the bearing damaged if happen how do we change? In our lumber mill operation in the process of the whole production. Surface treatment, will need to repair the bearing surface of oil, moisture removal; , daub material, the material evenly daub on bearing repair parts, fill strong; 。 And in a shorter lubrication interval, according to different corresponding calculating bearing manufacturer instructions, but you fit tight, consider the remaining clearance enough. First put bearing in gasoline cleaning, wipe residues of sludge and dust on the bearing, bearing all rusty wipe gently with the metallographic sandpaper polished, until no fingered rough feel.
