Tellerfedern bieten mehrere entscheidende Vorteile: Sie gew\u00e4hrleisten eine gleichbleibende Klemmkraft \u00fcber einen weiten Temperaturbereich, haben ein kompaktes axiales Profil und k\u00f6nnen in Reihe oder parallel geschaltet werden, um pr\u00e4zise Federraten und Vorspannungseigenschaften zu erzielen. Sobald das Drehmoment die durch die Tellerfedervorspannung eingestellte Reibungskapazit\u00e4t \u00fcberschreitet, beginnen die Scheiben progressiv zu rutschen und absorbieren \u00fcbersch\u00fcssige Energie ohne abruptes Trennen. Die Drehmomenteinstellung erfolgt durch Ver\u00e4ndern der Schraubenspannung am Federpaket. Diese Konstruktion bietet eine engere Drehmomenttoleranz und eine wiederholgenauere Leistung als Reibungsbegrenzer mit Schraubenfedern.<\/p>\n<p style=\"margin:10px 0;\"><strong>Zur\u00fccksetzen-Methode:<\/strong> Automatisch \u2013 kontinuierliches Durchrutschen und Wiedereinrasten<\/p>\n<p><strong>Am besten geeignet f\u00fcr:<\/strong> Pr\u00e4zisionsanwendungen, die geringe Drehmomenttoleranz, Temperaturstabilit\u00e4t und kompakte Einbaul\u00e4nge erfordern<\/p>\n<p><!-- Application Scenarios --><\/p>\n<h2 style=\"font-size:22px;color:#1a5632;margin-top:35px;border-left:4px solid #e8a020;padding-left:12px;\">Typische Anwendungsszenarien in der Landwirtschaft<\/h2>\n<div style=\"display:flex;flex-wrap:wrap;gap:16px;margin:15px 0;\">\n<div style=\"flex:1;min-width:280px;border-left:4px solid #e8a020;padding:12px 16px;background:#fff8ed;border-radius:0 8px 8px 0;\">\n<p style=\"font-weight:bold;color:#1a5632;margin:0 0 6px 0;\">Rotationsfr\u00e4sen und Kultivatoren<\/p>\n<p style=\"font-size:13px;color:#555;margin:0;\">Sch\u00fctzt das Getriebe der Bodenfr\u00e4se und die Zapfwelle des Traktors, wenn die Zinken auf vergrabene Steine, Wurzeln oder verdichtete Bodenschichten treffen, die extreme Drehmomentspitzen erzeugen k\u00f6nnen.<\/p>\n<\/div>\n<div style=\"flex:1;min-width:280px;border-left:4px solid #e8a020;padding:12px 16px;background:#fff8ed;border-radius:0 8px 8px 0;\">\n<p style=\"font-weight:bold;color:#1a5632;margin:0 0 6px 0;\">Manure Spreaders<\/p>\n<p style=\"font-size:13px;color:#555;margin:0;\">Protects the beater mechanism and gearbox from overload when encountering frozen clumps, foreign objects, or uneven material distribution in the hopper.<\/p>\n<\/div>\n<div style=\"flex:1;min-width:280px;border-left:4px solid #e8a020;padding:12px 16px;background:#fff8ed;border-radius:0 8px 8px 0;\">\n<p style=\"font-weight:bold;color:#1a5632;margin:0 0 6px 0;\">Feed Mixers &amp;

As a general rule, select a torque limiter rated at 1.2 to 1.5 times the implement&#8217;s normal peak operating torque. Consult your implement manufacturer&#8217;s specifications or contact our engineering team for personalized guidance.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\" style=\"margin-bottom:5px;\">\n<details style=\"border:1px solid #e0e0e0;border-radius:8px;overflow:hidden;\">\n<summary style=\"padding:14px 18px;background:#f5f9f5;cursor:pointer;font-weight:bold;color:#1a5632;font-size:15px;list-style:none;\" itemprop=\"name\">How do I know when the torque limiter has activated?<\/summary>\n<div itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\" style=\"padding:14px 18px;\">\n<p itemprop=\"text\" style=\"margin:0;font-size:14px;color:#444;\">Depending on the type: shear bolt limiters show a visibly sheared bolt; ratchet limiters produce a distinct clicking sound during slip; friction limiters emit a slight odor and sound during sustained slipping; automatic cam limiters produce a clicking sensation.

Shear bolt types are set by the bolt grade and cannot be adjusted \u2014 different torque ratings require different bolt specifications. Ratchet types have a fixed setting determined by the number and spring rate of the pawls.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\" style=\"margin-bottom:5px;\">\n<details style=\"border:1px solid #e0e0e0;border-radius:8px;overflow:hidden;\">\n<summary style=\"padding:14px 18px;background:#f5f9f5;cursor:pointer;font-weight:bold;color:#1a5632;font-size:15px;list-style:none;\" itemprop=\"name\">What maintenance does the torque limiter require?<\/summary>\n<div itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\" style=\"padding:14px 18px;\">\n<p itemprop=\"text\" style=\"margin:0;font-size:14px;color:#444;\">Regular greasing through the grease nipple (every 8 operating hours), visual inspection for wear or damage before each season, and replacement of worn friction linings (friction types) or keeping spare shear bolts on hand (shear bolt types).

Economy PTO (also called 1000 RPM PTO) is used for lighter implements to reduce engine RPM and fuel consumption. Our torque limiters are rated for both speeds. Select the spline size matching your PTO standard: typically 1 3\/8&#8243; Z6 for 540 RPM and 1 3\/4&#8243; Z20 for 1000 RPM.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\" style=\"margin-bottom:5px;\">\n<details style=\"border:1px solid #e0e0e0;border-radius:8px;overflow:hidden;\">\n<summary style=\"padding:14px 18px;background:#f5f9f5;cursor:pointer;font-weight:bold;color:#1a5632;font-size:15px;list-style:none;\" itemprop=\"name\">Do you offer OEM and private-label manufacturing?<\/summary>\n<div itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\" style=\"padding:14px 18px;\">\n<p itemprop=\"text\" style=\"margin:0;font-size:14px;color:#444;\">Yes, we provide full OEM manufacturing services including custom torque ratings, special spline configurations, custom markings, and private-label packaging.
