which a machine&#8217;s <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/rotor\/\">rotor<\/a> has been permanently \u2014 plastically \u2014 deformed so that its geometric centreline no longer runs straight. It produces a <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/vibration\/\">vibration<\/a> signature that looks deceptively like <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/unbalance\/\">unbalance<\/a> ili <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/misalignment\/\">misalignment<\/a>, but it carries one telltale fingerprint that sets it apart: <strong>high axial vibration at running speed<\/strong>. Recognising that fingerprint \u2014 and confirming it with <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/phase\/\">phase analysis<\/a> \u2014 is what stops an engineer from wasting hours trying to balance a fault that balancing can never cure.<\/p>\n<h2>1. The Nature of a Bent Shaft<\/h2>\n<p>A bent shaft is the result of the shaft material being stressed beyond its elastic limit, so the deflection does not spring back when the load is removed. Several mechanisms cause it:<\/p>\n<ul>\n<li><strong>Thermal stress:<\/strong> a hot rotor \u2014 for example a turbine rotor left to cool unevenly, or one not turned on a turning gear \u2014 can take a permanent bow as it sets. This is distinct from a temporary <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/thermal-bow\/\">thermal bow<\/a> that disappears once temperatures equalise.<\/li>\n<li><strong>Mechanical damage:<\/strong> a dropped rotor, a heavy impact, or rough handling during transport or overhaul.<\/li>\n<li><strong>Sympathetic failure:<\/strong> sustained operation under severe unbalance or misalignment can overload the shaft until it yields, turning one fault into another.<\/li>\n<\/ul>\n<p>It is worth distinguishing a true plastic bend from a recoverable <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/shaft-bow\/\">shaft bow<\/a>: a thermal or gravity bow may straighten out in service or after rest, whereas a bent shaft remains deformed and must be physically corrected or replaced.<\/p>\n<h2>2. The Vibration Signature of a Bent Shaft<\/h2>\n<p>The dominant feature is a high-amplitude peak at <strong>1\u00d7 the <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/running-speed\/\">running speed<\/a><\/strong>. The bend acts like a large, distributed heavy spot, so as the shaft turns it throws a once-per-revolution <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/centrifugal-force\/\">centrifugal force<\/a> very similar to that of unbalance. The distinguishing indicators are:<\/p>\n<ul>\n<li><strong>High axial vibration:<\/strong> the single most important sign. As a bent shaft rotates, it forces the components fixed to it \u2014 couplings, bearings, the rotor body \u2014 to move back and forth along the shaft axis. When the <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/axial-vibration\/\">axial vibration<\/a> exceeds roughly 50% of the radial (horizontal or vertical) level, a bent shaft or severe misalignment is strongly indicated.<\/li>\n<li><strong>Similar radial vibration:<\/strong> as with unbalance, the 1\u00d7 <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/radial-vibration\/\">radial vibration<\/a> is high.<\/li>\n<li><strong>Dominant 1\u00d7 frequency:<\/strong> the <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/spectrum\/\">spectrum<\/a> is usually dominated by the 1\u00d7 peak, though a 2\u00d7 component can also appear \u2014 particularly when the bend is near the centre of the shaft.<\/li>\n<\/ul>\n<p>Because the radial picture mimics unbalance so closely, the axial reading and the phase relationships described below are what actually clinch the diagnosis.<\/p>\n<h2>3. Differentiating a Bent Shaft from Misalignment<\/h2>\n<p>A bent shaft and <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/misalignment\/\">shaft misalignment<\/a> can look almost identical in amplitude terms, since both raise axial vibration. The way to separate them is <strong>phase analysis<\/strong>, using the timing relationship a <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/tachometer\/\">tachometer<\/a> reference makes possible.<\/p>\n<ul>\n<li><strong>Procedure:<\/strong> take radial and axial <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/phase-angle\/\">phase<\/a> measurements at both the inboard and outboard bearings \u2014 four readings in all.<\/li>\n<li><strong>Bent-shaft indication:<\/strong> if the shaft is bent, the axial phase readings taken at the same radial position (for instance, the top of each bearing) will be roughly <strong>180\u00b0 out of phase<\/strong> with one another. As one end of the rotor is pushed forward by the bow, the other end is pulled back.<\/li>\n<li><strong>Misalignment indication:<\/strong> in classic angular misalignment, those same axial phase readings tend to be approximately <strong>in phase<\/strong> (close to 0\u00b0 apart).<\/li>\n<\/ul>\n<p>Taking phase readings across the coupling provides further, often definitive, evidence to tell the two faults apart. A <a href=\"https:\/\/vibromera.eu\/bs\/calculators\/vibration-phase-angle\/\">phase-angle calculator<\/a> is handy for combining and comparing these vector readings during the assessment.<\/p>\n<h2>4. Differentiating a Bent Shaft from Unbalance<\/h2>\n<p>Both conditions create high 1\u00d7 radial vibration, but pure <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/unbalance\/\">unbalance<\/a> generates very little axial vibration. So a high 1\u00d7 peak <em>combined with<\/em> significant axial motion points away from unbalance alone and toward a bent shaft or misalignment.<\/p>\n<p>There is also a practical, almost diagnostic, behaviour during correction. A bent shaft cannot be fixed by <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/balancing\/\">balansiranje<\/a>: adding <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/correction-weight\/\">correction weights<\/a> may lower the vibration at one bearing while raising it at another, because the bend is a distributed deformation rather than a single localised mass. If a rotor proves stubborn or impossible to balance \u2014 the readings refusing to converge to an acceptable <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/residual-unbalance\/\">residual unbalance<\/a> \u2014 that frustrating behaviour is itself strong evidence of a bent shaft rather than simple unbalance.<\/p>\n<h2>5. Confirmation and Practical Measurement<\/h2>\n<p>The definitive confirmation is mechanical: mount the rotor on V-blocks or between lathe centres and sweep the shaft with a dial indicator to measure its <a href=\"https:\/\/vibromera.eu\/bs\/glossary\/run-out\/\">runout<\/a> (total indicator reading). A significant, repeatable runout that peaks at one angular position confirms a physical bend, after which the shaft must be straightened or replaced. A <a href=\"https:\/\/vibromera.eu\/bs\/calculators\/shaft-radial-runout\/\">shaft radial runout calculator<\/a> helps relate the measured TIR to the true eccentricity of the centreline.<\/p>\n<p>Before a machine is opened up, however, the fault is usually first identified on the running equipment. A portable two-channel analyser such as the <a href=\"https:\/\/vibromera.eu\/bs\/proizvod\/balanset-1\/\">Balanset-1A<\/a> lets the technician capture 1\u00d7 amplitude and phase simultaneously in the radial and axial directions at both bearings, in the machine&#8217;s own bearings at operating speed \u2014 exactly the four-point phase set needed to separate a bent shaft from misalignment, and to confirm that the rotor genuinely will not balance. That on-site reading turns an ambiguous high-1\u00d7 symptom into a confident diagnosis before any disassembly begins.<\/p>\n<hr>\n<p><a href=\"https:\/\/vibromera.eu\/bs\/glossary\/\">\u2190 Back to Main Index<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>A guide to identifying a bent shaft using vibration analysis, focusing on its characteristic high axial vibration and its relationship with misalignment.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"ai_generated_summary":"","footnotes":""},"categories":[114,109],"tags":[],"class_list":["post-56","glossary","type-glossary","status-publish","hentry","category-analysis","category-glossary"],"_links":{"self":[{"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/glossary\/56","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/types\/glossary"}],"version-history":[{"count":1,"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/glossary\/56\/revisions"}],"predecessor-version":[{"id":101273,"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/glossary\/56\/revisions\/101273"}],"wp:attachment":[{"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/media?parent=56"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/categories?post=56"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vibromera.eu\/bs\/wp-json\/wp\/v2\/tags?post=56"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
