SKF bearing type: large maintenance machinery bearings

To avoid the phenomenon of water XiaoYao: there are other similar water? Xiao zhang: they are assembling estimate is crown outfit! And assembly car rear thrust pad is bad over there. If the room temperature is lower, proper heating surface of tooling; , bearing in the hole is not round, bearing box distortions, the bearing surface is not flat, cases of hole diameter is too small. 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; 。 Including, oil cylinder oil seal, hydraulic cylinder, the structure design of the structure design of shaft axis is to determine all reasonable shape and structure size of shaft, and important step in the design for shaft. Resistance to impact load, the need for additional solid lubrication protection ( Such as graphite) BESLUXPLEXEH - /舌鳎 amp; 嗯- - - - - - /G。 Because of the coating area is small, so to prevent the high frequency of shaft current effect is better, outer spherical bearing is a bearing outer ring looks like a sphere, bearing sealing cover automatically self-aligning bearing on both sides of the belt. The main components in the scroll compressor is two same shape but relative stagger ° phase Angle position of involute scroll wrap, it is fixed vortex disk, while the other one is driven by the eccentric shaft, and the fixed scroll wrap around its axis axis orbit of orbiting scroll wrap. After will spray lubrication oil atomizing spray on the surface of the friction, lubrication method, suitable for high speed bearing, high speed light load bearing can choose dispersion droplets or fog lubrication; Highway overload should choose injection lubrication. Failure cause analysis: the study found that the main shaft pine knife sword out of action with manipulator moves not harmonious, the specific reason is limit switch installed in pressurization of the end of the cylinder, the cylinder piston action in place, the pressure cylinder piston is not in place in time, resulting in the clamping structure of the manipulator is not completely let go when the sword out, seriously damaged the tie rod ball and tighten screw. Metal substrate in the process of friction for the most part bear the load, the development of high temperature and overloading, complex conditions, such as low speed, including lining and corrosive self-lubricating bearing materials is a priority. Motor factory at the site, in addition, the coating on bearing anti-rust oil has good lubrication performance, for the purposes of bearing or bearing grease filling, can not directly use cleaning. The dc resistance under high temperature is also can achieve G ohm range, insulation performance is good; Ceramic roller has excellent wear resistance, low to the requirement of lubrication, especially suitable for high speed, low friction and low temperature operation occasion; Under the condition of dry friction running in good condition; For small size of the rolling bearing, using the ceramic insulation bearing roller has the good economic performance.
