CNC machine tool alarm fault maintenance,One setFAGOR 8025MG,The model is...XK5038-1CNC machine tool,Feed shaft alarm occurs frequently on machine tools,At least once a day,As little as5~6Once in a day,Power off half an hour after the power back on normal。
Because the temperature is lubricated、Rotational speed、load、Environmental impact,The values in the table represent approximate temperature ranges only。The role of bearing lubrication is lubrication on the fatigue life and friction of rolling bearings、wear、Temperature rise、Vibration and so on have important effects,There is no normal lubrication,The bearings dont work。Analysis of tapered roller bearing damage...
1.Aligning ball bearing installation Whether the bearings are installed correctly,Influence accuracy,Life span,property。therefore,The installation design and assembly of aligning ball bearings are fully studied and the following conclusions are drawn,Standard projects typically work as follows: aStrong stamping is not allowed,Direct hammering is not allowed...
The shaft is supported radially and axially by two bearings,now,The imported bearing on one side is called the fixed side bearing,It bears both radial and axial loads,It acts as the relative axial displacement between the fixed shaft and the bearing box。 Lets call the other side the free side,Radial load only,The axis can move relative to each other,In this way, the expansion part of the shaft and the spacing error of the mounting bearing caused by the temperature change are solved。
During the design of the new spindle,SelectINABefore bearing,Consider spindle performance parameters first,Roughly identify the most critical performance,Then enter further probe。(include:Spindle speed,Spindle accuracy,Spindle rigidity,Spindle life,Spindle heating,Spindle reliability)
ZKLF40115-2RS-2AP,INABearing characteristic application,The size of the maximum load bearing is the same as that of the standard bearing,Danet、The outer ring has a loading slot,Increased the number of balls loaded,Increased the rated load,Mainly applicable cage:Steel plate stamping cage(Wave form、coroniform…single-row;SThe shape…biserial)。
ZKLF40115-2Z,How to eliminate the noise of imported bearings,Bearings in normal use,The sound is perfectly normal during its operation,No special noise,Or really loud noises。
ZKLF40115-2Z-2AP,INABearing temperature rise causes,Bearing mechanism assembly if too tight,Insufficient clearance can also cause flange bearing temperature to rise;Bearing penetrationINAThe bearing should turn flexibly without a sense of retardation。
ZKLF50115-2RS,INABearing damage cause,The way bearings are assembled:Because bearings are high-precision products,If the assembly is not proper, it is easy to cause damage to the pump shaft and bearing channel,Lead toINABearing failure。
ZKLF50115-2RS-2AP,INABearing assembly precautions,When the user buys the bearing, he will generally only be told in what model、Lv.,There are few requirements for bearing clearance,Business people have to askINAService conditions of bearings、amongINABearing speed、temperature、Fit tolerances are directly related to the selection of bearing clearance。
