Oil-free lubrication bearing, bearing the authenticity

Bearing lubrication concepts: bearing lubrication purpose: release bearing surface,
Eliminate wear, reduce friction, prevent burning stick)
Protect the bearing (
From corrosion, prevent damage of external impurities)
Reduce friction and friction losses.
A = bearing;
B = bearing figure along the shaft of the induction voltage between bearing and, if the voltage between the shaft and bearing current through each bearing will be in the same direction.
Can say, bearing damage or clearance over limit should be allowed to replacement;
Rolling bearing damage, loose kuang should change;
Oil lubrication system should be cleaned free of traffic.
Facilitate the installation of the bearings and removing choose bearing type, whether bearing installation disassembly convenient, also must be thoughtful, especially for large and super large bearing installation and removal is particularly important.
Standard ~ or less or less, so can only live to the bearing with a hammer to hit, I hit the nearly hundred ~ take ten minutes later, the bearing is smashed down finally.
Like grease choice: the choice of grease is according to the requirements of the bearing rotating speed, heat resistance, noise and choose starting torque, etc, required business people to know a lot about the performance of all kinds of grease.
Bearing lubricating oil: the scope of application of a wide range of use, the high and low temperature, high load, high and low torque, etc, can be used, such as mobile phone, digital camera on the bearing can also be used;
Can also be on powder metallurgy bearings, and the water pump, can be applied to the ball screw and other products.
Maintains a broken solution: check the conditions of use;
Check the lubrication conditions;
To study the choice of the cage.
Pay attention to the bearing use;
The shaft and bearing box rigidity.
Because the load is small, the Ar in a small amount of deformation, both to reduce the stress peak, and has the deformation Ar processing reinforcement and stress and strain induced martensite phase transformation and reinforcement.
Focused on fire prevention unit for a long time continuous fever faults and unit directly led to the collapse, the wrong operation and maintenance methods of the fire, with variable blade unit is of particular importance to prevent the blades cannot feathering failure occurred at the same time.
Detection methods and the selection of measuring benchmark position of the shaft coupling axis position deviation is certain benchmark position is very important, such as centrifugal horizontal pump unit, fan without growth, such as equipment, benchmark area should choose the motor end;
With growth, with a coupler large blower, turbine, steam turbine, the benchmark parts should consider motor side in the adjustment of cumulative error produced in the process of value, at the same time also need to consider the influence of thermal expansion of shaft center, the choice of benchmark parts should try to meet the long operation period, standard parts, and thermal expansion centerline offset small parts as a benchmark.
British wind institutions to incomplete statistics, as of (date) (month) (year), the global total of wind turbines to a major accident, the fire accident, of the total, %, ranks the first place.
