Do not bring the spindle speed of inverter no S - if not controlled system
S control signal output, then we can check whether there is any shift on system control signal output to determine whether there is a problem.
Depth in, these bearings are widely used in the precision grinding machine on motorized spindle and the spindle, grinding the axial load is not big, often using contact Angle for ° angular contact ball bearings.
Is there will be no sound!
For this maintenance, SKF bearing failure scale factors in advance: improper lubrication: % of bearing failure reason in advance.
Bearing during operation, regular inspection by the regulation, if fever, noise, vibration, etc. , to stop in time to find the reason, fault, bearing such as found serious fatigue spalling, pit, crack, hardness of the oxidation corrosion, wear and tear down to HRC&
lt;
Or have too much noise can't adjust, should be replaced in a timely manner.
Overview in the process of machining cast iron, cast iron machined surface barriers often to happen, is casting factory casting quality has a problem, the other side is a machine processing factory processing error.
Heat curing, and improve the material performance and speed up the material curing time;
, amount of added lubrication oil lubrication and interval, according to the table below, according to the amount of oil in the table, can achieve at least hours of supplementary lubrication.
Boot wear appeared again two days later, the vibration value is more and more big, the enterprise again after removal of bearing pad of the copper foil way in times of emergency handling, equipment operation days later again vibration.
Countermeasures: change meets the design requirements of aperture bearing box, if that is the catastrophic damage, LTD bearing to determine the root cause of the problem, because may be outside lubrication factor.
Overcome high-speed roller bearing light load sliding measures: in roller has high enough fatigue life are made of high strength lightweight materials keep frame, to reduce the weight.
The material the advantage of on-line repairing shaft wear and tear, through the analysis of the measured numerical calculation, determine the relative position of two axes in space, and then adjusted according to the calculation result.
Aimed at the situation we have increased oil pressure at the scene, with precision grade would choose levels, sometimes also want to see the material, and the processing technology, the theory of the superior is a partial bottom, level co-operating with grinding.
At present, the global wind turbines of publicly reported incidence of fires per year on average, up, and the researchers think that at least more than a year wind turbines on fire accident happened.
