The difference between the inner bearing: normal temperature bearing and high temperature bearing

As is known to all, aircraft engine is an important part of aircraft aircraft engine bearings by burning after the high temperature of gas turbine, the turbine through the shaft drive. It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc. , especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion. First small make up feel without rolling bearing, is largely because, if the rolling bearing was badly smashed and the lock will immediately in the situation, so in most of the high-speed shaft, multi-purpose are bearing shell, is not only the engine, is this, and are like large compressor USES is the bearing shell! And if pack rolling bearing on the engine crankshaft, feel there is no way to install, because everybody wants to know, rolling bearing of ball track cannot have stitched, if have this phenomenon, it is easy to damage, this is largely without the cause of the rolling bearing. The first hammer assembly, obtained by contact velocity or acceleration sensor, a fixed on the bearing cover directly or through magnetic adsorption on it, is sometimes called a shell vibration, vibration. In the use of the wheel hub bearing and install please note the following items: to large extent to ensure the safety and reliability, it is recommended that you no matter how long their cars are often should check the wheel hub bearing - — Pay attention to whether the bearing has worn early early signal: including any rotating friction noise or hanging abnormal combination wheel in turn. Small make up the main today to share the lubrication part of the spring balance mechanism and maintenance cycle, the balance device has simple structure, balance the effect is good, easy to adjust, and reliable work, but to increase the load inertia and joint axis of the robot. Go outer shell holes and bearing outside diameter with too loose, Commonly known as the 'outer') Due to shell the matching of the aperture and the choice of bearing outside diameter is too loose, sliding surface between them. Be butter covering many ABS ABS probe sensor fault cases was caused by a bearing too much butter, too much of the butter when installing wheel is easy to be pushed to the probe. In addition to the fan impeller part of the box is also very important core part in the daily maintenance work of we have to check box fan impeller blade fracture, dust, wear, and so on and so forth, to find problems in a timely manner. , ring and rolling body has no obvious pitting and spalling trend before, only need grinding outer ring ( Due to the special heat treatment process, the outer ring can maintain original cause) hardness with grinding several times Surface can restore bearing accuracy. Mainly refers to the inner diameter d mm or less deep groove ball bearings, but the inside of the Team to do so I will not happy! Since I will often send their products, S - — Bearing ring through high temperature tempering processing, working temperature can reach ℃, according to whether the heart, is divided into: self-aligning bearing, self-aligning bearing ( Rigid bearing) 。 Lubrication method, oil-gas lubrication way, the oil circulation lubrication two, for the main shaft lubrication also has two type: oil mist lubrication method and way of injection lubrication.
