Varvel Worm Gearbox - F RS 150 - Output Shaft Ø55mm

Varvel FRS150 Ø55 mm Gearbox: Performance and Robustness for Industrial and Agricultural Transmissions

Designed to meet the demands of the most challenging production environments, the Varvel FRS150 worm gear reducer combines mechanical strength, compactness, and high adaptability. It ensures reliable, precise, and low-maintenance transmission, even during intensive use in industrial or agricultural settings.

Originating from the Italian region of Emilia-Romagna, renowned for its expertise in mechanical transmission, the FRS150 integrates seamlessly into numerous equipment such as conveyors, mixers, transport systems, agricultural machinery, automated lines, and labeling equipment, especially in installations operating continuously for extended periods.

At Dymatec Industries, every FRS150 gearbox undergoes rigorous quality control and personalized adjustment to ensure optimal integration into your existing production lines.

Applications of the FRS150 Ø55 mm

Thanks to its ability to transmit high torque at low speed and its great installation flexibility, the FRS150 is used in many industrial and agricultural sectors.

It is particularly used on conveyors and belts for transporting parts, packages, or bulk materials, on mixers and agitators used in the food, chemical, or pharmaceutical industries, as well as on screw conveyor and dosing systems ensuring precise control of material flows.

It is also suitable for agricultural machinery such as spreaders, seeders, irrigation systems, or harvesting equipment, as well as for lifting devices, motorized gates, industrial valves, or automated hatches. It is also found on pumps and compressors operating at low speeds, on packaging and labeling lines requiring a stable pace, and on various handling equipment such as lifting tables or automated transfer systems.

Its low noise level and reduced footprint, characteristics inherent to worm gear reducers, make it a particularly suitable solution for environments where discretion, compactness, and durability are essential.

G Version Coupling: Reliability and Motor Protection

The FRS150 is equipped with a G version motor-reducer coupling ensuring direct, stable, and efficient torque transmission. This system helps to limit the risk of motor shaft seizing during prolonged shutdowns, reduces maintenance interventions, and improves the overall longevity of the transmission assembly.

Available Reduction Ratios

The FRS150 has 12 reduction ratios ranging from 5 to 100, allowing precise adjustment of output speed and torque according to each application. The calculation principle remains simple: motor speed divided by the reduction ratio corresponds to the output speed.

Mounting Configurations

The FRS150 can be installed in several configurations to adapt to the constraints of each machine, with housing mounting version PC, FL output flange, foot mounting, or a torque arm equipped with a silent-block to dampen vibrations and dynamic forces.

Ø55 mm Hollow Shaft and Output Configurations

The gearbox is equipped as standard with a Ø55 mm hollow shaft, allowing a direct, rigid, and backlash-free connection with the driven machine. Depending on the needs, it can also be available in single solid shaft (AS) or double solid shaft (AD) versions.

Compatibility with IEC Standard Motors

The FRS150 is compatible with standardized three-phase motors IEC 90, IEC 100, IEC 112, and IEC 132, thus covering a wide range of powers and facilitating its integration into numerous industrial configurations.

Motor Flange Compatibilities

The FRS150 accepts various standard motor flanges, including IEC 100 B5 and B14, IEC 112 B5 and B14, IEC 132 B5 and B14, as well as some configurations in IEC 160 B5 depending on the versions. This compatibility guarantees a reliable mechanical connection and optimal power transfer between motor and gearbox.

Customization Options

The FRS150 can be configured with numerous technical options to meet specific needs:

• Double output shaft (AD)
• Single output shaft (AS)
• ASC protective cover
• Internal TLI or external TLE torque limiter
• Reduced backlash version GRM
• VB worm extension
• Viton VIT seals for aggressive environments
• ATEX certification for explosive atmospheres.

Replacement and Equivalents

For any replacement operation, it is essential to check for a Ø55 mm output shaft. Transmitting the nameplate of the old equipment allows for quick identification of an equivalent or superior solution, perfectly suited to the existing installation.

The FRS150 is compatible as a replacement for gearboxes from manufacturers such as Motovario, Bonfiglioli, SITI, STM, SEW-Eurodrive depending on configuration, as well as Rossi.

The team of mechanical transmission specialists at Dymatec Industries supports each project to ensure a quick restart without major modifications to the installation.
