RS-RT

Product catalog summary
Torque Limiter: The torque limiter allows for adjustable torque transfer, gearbox protection from peak loads, easy disconnection of the drive unit, and manual operation during power failures. The slip torque is adjustable from maximum to zero, resuming rotation when torque falls below the set value.
Speed Limiter: The speed limiter stops the gearbox after a set time using limit switches, with adjustable operating times ranging from 12 to 170 seconds.
General Specifications: RS-RT gearboxes offer 55 ratios with a maximum output torque of 3020 Nm, designed according to BS721 standards with a lifespan of 10,000 hours at SF1. Housing materials vary from aluminum to cast iron.
Components: Gearboxes feature steel worms, bronze wheels, steel shafts, and keys. Bearings are ball or roller types, and oil seals are made of NBR or FKM. Lubricant is synthetic long-life oil, ISO VG 320.
Protection and Painting: Gearbox body protection is IP66, with motor flanges at IP20. Housing is painted with epoxy powder in RAL 7012 color from size 110 onwards.
Coupling Description: The coupling system includes a steel reducer-side hub, thermoplastic elastomer spider, and aluminum or steel motor-side hub, offering flexibility and high torsional rigidity.
Flanges and Couplings: Various flange and coupling types are available, with specifications for IEC and NEMA standards.
Motor and Gearbox Coupling: Specifications for motor coupling with key/keyway fittings for IEC input, including coupling code with IXEF black spider.
Gearbox and Motor Designation: Designation includes gearbox type, motor form, reduction ratio, and size, with input coupling and keyway details.
Options and Configurations: Options include non-standard hollow shafts, heavy-duty output bearings, additional flanges, reduced end play, and non-standard lubrication.
Modularity and Flexibility: VARVEL products are modular and flexible, allowing quick assembly with standard tools. The VARsize® program aids in product configuration.
Mounting Positions: Details on standard and non-standard mounting positions for different gearbox types.
Weights and Lubricants: Weight and lubricant specifications for different gearbox models, indicating required lubricant volume.
Service Factor: Service factor FS1.0 is defined for typical operations, with guidance for operations outside standard temperature ranges.
Duty Types: Defined by CEI EN 60034-1/IEC34-1 standards, including continuous and periodic intermittent duties.
External Loads: Guidelines for checking radial loads based on output speed, mounting position, and transmission element type.
Specifications and Standards: European Directive 2006/42/EC-ATEX applies to machines in explosive environments. VARVEL-ATEX gearboxes have metallic housings and FKM oil seals.
Directive Code Breakdown: ATEX directive categorizes equipment into Group I (mining) and Group II (surface industries), with protection levels and environmental conditions specified.
Installation and Operation: Ensure correct gearbox selection and stable support structure. Gearboxes can rotate in either direction and should be stopped if defects occur.
Handling and Maintenance: Use designated lifting points and protect components during repainting. For long-term storage, apply anti-oxidants and protective grease.
Product Compliance: VARVEL series comply with Group II, Category 2 or 3, for hazardous zones with gas or dust presence.
Installation: Ensure the drive unit matches order specifications and is stable to prevent vibrations.
Commissioning: Operate in both directions, stopping immediately if improper operation occurs.
Maintenance: Avoid full load for the first 20-30 hours. Units are lubricated for life with synthetic lubricant.
Handling and Transport: Ensure stable positioning and secure fastening during lifting and transport.
Painting: Protect seals and shafts during painting.
Long-term Storage: Store in a dry, dust-free environment, applying rust protection for storage over three months.
Disposal: Separate metal parts during scrapping and dispose of lubricants responsibly.
