Due to the cycle of wind power gear box, use the ISOVG viscosity lubricating oil, so if it is found that lambda is less than we like only by reducing the bearing raceway and the roughness of the roller to improve the lubrication effect.

/ CU aircraft turbine engine bearing high and low temperature grease, adopting micro molybdenum graphite combination for improved in this paper, the lubrication, similarly, the gas has been used as a lubricant at high temperature, as a result of the aircraft engine bearing high temperature, rapid and overload, the traditional oil lubrication sometimes doesn't work.
When required, the bearing can be added to add in this article, for example: 'the needle roller bearings, full, drawn cup, without inner ring' or 'ring needle roller bearing cage, mechanism, without inner ring'.
Of course, the local tyrants ceramic directly!
Chocolate bearing large logo on the cover, open the packaging, each bearing novel special packaging, feeling, as if to whistle sugar may be brand is Chocolate, but I still have a impulse want to bite, packaging low-key, bearing special feeling, can consider to start to try!
Skatejun -
Methyl amino acetonitrile tPro high-speed bearing special slippery for cover, extremely powerful brand effect, at the same time, the standard of the PRO suggests that this is a professional attitude, golden luxury bearing show that implies that the bearing slide movement extremely, of course, if want to try to his board.

And do not require complicated outsourcing and offline operation can complete, and not to damage the original equipment, repair after the original equipment service life is also the first one.
Pick up tools and parts, usually this kind of bearing has space between the inner hole and shaft, with the top silk, eccentric sleeve or be a set of bearing inner ring is fixed on the shaft, and the shaft rotation.
Here we illustrate to explain all kinds of machinery and equipment noise source, simple periodic force is by the axis of rotation, the flywheel rotation system such as static and dynamic imbalance caused by the eccentric force.
Due to the roller can be loaded very, the radial load capacity is extremely high, row cylindrical roller bearings with a cylindrical hole, some the size of the bearing can also supply with cone hole, low set non-standard sets of Mosaic non-standard sets a common emergency repair measures, grind the bearing surface, clean, dry, solid, rough;
。
The periodic signal can be installed on the bearing seat of sensors (
Type speed or acceleration)
To receive, and through the analysis of the vibration signal to diagnose the faults of the bearing.
The knowledge of the rolling bearings of rolling bearing structure developed on the basis of the sliding bearing of rolling bearing, its working principle is based on rolling friction instead of sliding friction, as the two ring, set of rolling elements and a cage of strong commonality, a high degree of standardization, seriation of mechanical components.
As, due to many as the axis of rotation, so the inner ring need interference fit, installed with a hammer knock occasions, as a last resort to mat mat, circle piece of homework, deep groove ball bearing is for common types of rolling bearing, dustproof cover gasket material for sheet metal, only simple prevent dust from entering the bearing raceway.
Main causes include: early to open the bearing packing before use, cause pollution;
When installation work environment is not clean, cause pollution;
Bearing of the working environment is not clean, working medium pollution, etc.
