bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]Its function should be to support,The literal interpretation is used to bear the shaft,But thats only part of the story,Supporting its essence is to be able to bear radial loads。It can also be understood that it is used to hold the shaft。It just fixed the axis so that it could only rotate,And control its axial and radial movement。Motor without bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,
1. Contact fatigue failure Contact fatigue failure refers toIKOThe bearing working surface fails due to the action of alternating stress。Contact fatigue spalling occurs in turntable bearings[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]Working surface,Often accompanied by fatigue cracks,It is first generated from the maximum alternating shear stress below the contact surface,It then expands to the surface to form different peeling shapes,Such as pitting or flaking of pitting,Exfoliation in small sheets is called shallow exfoliation。On account of
Many models of silver rail are interchangeable,Mainly look at the specifications of the guide rail,typology,For example, on the silver flange type,15The size of,I opened a exchange silver Thai flange15Size of the slider up,Because of their size,Type similarity,Performance is comparable!
Spindle is the key component of machine tool,Its performance will directly affect the rotation accuracy of the machine tool、Rotational speed、rigidity、Temperature rise, noise and other parameters,In turn, it will affect the processing quality of the workpiece,For example, dimensional accuracy of parts,Surface roughness and other indicators。therefore,In order to maintain excellent machine tool processing ability,Must be equipped with high performance bearings[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]。Bearings for machine tool spindles[bearing:bearing,thkbearing,trbearing,NSKbearing
Generally speaking,TIMKENbearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]Rolling bearing[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]It does not produce noise by itself。Commonly felt“bearing[bearing:bearing,thkshaft
Grease in bearings[bearing:bearing,thkbearing,trbearing,NSKbearing,NTNbearing,SKFbearing,NACHIbearing,KOYObearing,HCHbearing,IKObearing]When lubricating with other friction parts,The solid friction between the friction surfaces of the machine is replaced by its internal friction。therefore,The viscosity of grease has a great influence on the power consumption of the machinery using grease。If the grease used is of high viscosity,Obviously the friction loss will be more。 &n
