This version is equipped with a \u003cstrong\u003eØ20x40 mm solid output shaft\u003c\/strong\u003e, an essential feature that gives it a transmission capacity suitable for medium-torque industrial applications. Robust, compact, and reliable, the \u003cstrong\u003eVarvel FRD02 Ø20x40 mm\u003c\/strong\u003e naturally integrates into demanding industrial environments: conveyor lines, handling systems, packaging machines, automated process equipment, and even food processing facilities. Thanks to \u003cstrong\u003eVarvel's\u003c\/strong\u003e proven design, recognized for decades in the European and global markets, it guarantees quiet operation, consistent transmission, and optimal longevity in continuous service, even under intensive use conditions.\u003c\/p\u003e\n\u003ch2 id=\"comment-fonctionne-le-varvel-frd02-820\" class=\"text-md-600 text-grey-900 mt-10 mb-4 scroll-mt-4 wrap-break-word first:mt-0\"\u003eHow does the Varvel FRD02 work?\u003c\/h2\u003e\n\u003cp class=\"text-sm-400 overflow-wrap-anywhere mb-5 wrap-break-word last:mb-0\"\u003eThe \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e relies on a high-precision helical gear train to convert a high input speed into a reduced output speed, with a proportionally increased torque. Unlike conventional spur gears, the helical meshing used by \u003cstrong\u003eVarvel\u003c\/strong\u003e ensures smooth and progressive transmission, distributing forces over several teeth simultaneously. This results in a significant reduction in vibrations, controlled noise levels, and minimized wear throughout the geared motor. The standardized input of the \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e allows direct coupling with a standard IEC electric motor, without additional adaptation parts, which considerably simplifies mechanical integration and reduces commissioning times.\u003c\/p\u003e\n\u003ch2 id=\"quelles-sont-les-compatibilites-moteur-du-frd02-820\" class=\"text-md-600 text-grey-900 mt-10 mb-4 scroll-mt-4 wrap-break-word first:mt-0\"\u003eWhat are the motor compatibilities of the FRD02?\u003c\/h2\u003e\n\u003cp class=\"text-sm-400 overflow-wrap-anywhere mb-5 wrap-break-word last:mb-0\"\u003eThe \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e has been designed to adapt to standardized electric motors \u003cstrong\u003eIEC 56, IEC 63, IEC 71, and IEC 80\u003c\/strong\u003e, thus covering a wide range of motor powers commonly used in industry. The motor connection is made via a \u003cstrong\u003eB5 or B14 flange\u003c\/strong\u003e depending on the chosen configuration, two widely used standards that guarantee total interchangeability with most motors on the market. The \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e also integrates an \u003cstrong\u003eelastic coupling\u003c\/strong\u003e that absorbs starting shocks, compensates for slight misalignments, and protects both the gearbox and the motor against momentary overloads. This extended compatibility makes the \u003cstrong\u003eFRD02 Varvel\u003c\/strong\u003e a particularly popular solution for fleet renewals or modernization of existing installations.\u003c\/p\u003e\n\u003ch2 id=\"quelles-sont-les-dimensions-des-brides-moteur-b5-et-b14-820\" class=\"text-md-600 text-grey-900 mt-10 mb-4 scroll-mt-4 wrap-break-word first:mt-0\"\u003eWhat are the dimensions of the B5 and B14 motor flanges?\u003c\/h2\u003e\n\u003cp class=\"text-sm-400 overflow-wrap-anywhere mb-5 wrap-break-word last:mb-0\"\u003eThe flange dimensions of the \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e scrupulously comply with IEC standards, guaranteeing full compatibility with motors on the market. For the \u003cstrong\u003eB5 flange\u003c\/strong\u003e, the standardized diameters are \u003cstrong\u003eØ120 mm in IEC 56\u003c\/strong\u003e, \u003cstrong\u003eØ140 mm in IEC 63\u003c\/strong\u003e, and \u003cstrong\u003eØ160 mm in IEC 71\u003c\/strong\u003e. For the \u003cstrong\u003eB14 flange\u003c\/strong\u003e, the diameters are \u003cstrong\u003eØ80 mm in IEC 56\u003c\/strong\u003e, \u003cstrong\u003eØ90 mm in IEC 63\u003c\/strong\u003e, \u003cstrong\u003eØ105 mm in IEC 71\u003c\/strong\u003e, and \u003cstrong\u003eØ120 mm in IEC 80\u003c\/strong\u003e. Compliance with these standardized dimensions by \u003cstrong\u003eVarvel\u003c\/strong\u003e is a guarantee of reliability during assembly: no machining or adaptation is necessary, which reduces installation costs and the risk of error during assembly.\u003c\/p\u003e\n\u003ch2 id=\"quels-sont-les-rapports-de-reduction-disponibles-820\" class=\"text-md-600 text-grey-900 mt-10 mb-4 scroll-mt-4 wrap-break-word first:mt-0\"\u003eWhat reduction ratios are available?\u003c\/h2\u003e\n\u003cp class=\"text-sm-400 overflow-wrap-anywhere mb-5 wrap-break-word last:mb-0\"\u003eThe \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e stands out for its particularly wide reduction range, allowing it to cover a very broad spectrum of industrial applications with a single gearbox model. The available ratios are: \u003cstrong\u003e2.25 \/ 2.5 \/ 2.80 \/ 3.15 \/ 3.55 \/ 4 \/ 4.5 \/ 5 \/ 5.6 \/ 6.3 \/ 7.1 \/ 8 \/ 9 \/ 10 \/ 11.2 \/ 12.5 \/ 16 \/ 20 \/ 25 \/ 31.5 \/ 40 \/ 50\u003c\/strong\u003e. This exceptional range allows for very fine adjustment of the output speed according to the constraints of each industrial process, whether it is a slow, high-torque application or a moderately fast drive.

This \u003cstrong\u003eØ20x40 mm\u003c\/strong\u003e shaft allows direct mounting of \u003cstrong\u003epulleys, sprockets, rigid or flexible couplings\u003c\/strong\u003e, without requiring specific intermediate parts. The robustness of this shaft, combined with the manufacturing quality of \u003cstrong\u003eVarvel\u003c\/strong\u003e, guarantees optimal fatigue resistance even under repeated stress or in case of significant radial load.

The \u003cstrong\u003eB3 foot mounting\u003c\/strong\u003e is the classic solution: the gearbox is placed and bolted onto a chassis or metal support, offering great stability and facilitating maintenance. The \u003cstrong\u003eflange mounting\u003c\/strong\u003e allows direct attachment to the front face of the frame or machine, ideal when floor space is limited or the machine's design requires it. This mounting flexibility, designed by \u003cstrong\u003eVarvel\u003c\/strong\u003e to meet real-world needs, facilitates both new installations and replacement operations on existing equipment, without structural modification of the frame.\u003c\/p\u003e\n\u003ch2 id=\"quelles-sont-les-equivalences-du-varvel-frd02-457\" class=\"text-md-600 text-grey-900 mt-10 mb-4 scroll-mt-4 wrap-break-word first:mt-0\"\u003eWhat are the equivalents of the Varvel FRD02?\u003c\/h2\u003e\n\u003cp class=\"text-sm-400 overflow-wrap-anywhere mb-5 wrap-break-word last:mb-0\"\u003eThe \u003cstrong\u003eVarvel FRD02\u003c\/strong\u003e with \u003cstrong\u003eØ20x40 mm\u003c\/strong\u003e shaft is recognized as a reliable replacement solution for many coaxial gearboxes on the market.
