Serie F - Shaft mounted gear units - Atex

Product catalog summary
Overview: The document addresses safety directives related to explosion risks in machinery, focusing on the ATEX Directive 2014/34/EU, which takes precedence over the Machinery Directive 2006/42/EC for explosive atmospheres. It covers equipment classification and protection levels for such environments.
Key Directives:
  • ATEX Directive 2014/34/EU: Effective from April 20, 2016, this directive applies EU-wide, covering mechanical, hydraulic, pneumatic, and electrical equipment in explosive atmospheres.
  • Machinery Directive 2006/42/EC: Provides general explosion safety requirements, but ATEX Directive is prioritized for specific explosion risks.
Equipment Classification:
  • Zones: Equipment is classified for zones 1, 21, 2, and 22, based on the frequency of explosive atmosphere formation.
  • Protection Levels: Equipment must meet manufacturer-specified protection levels: very high, high, or normal.
  • Groups: Group I is for mining, Group II for other explosive areas. BONFIGLIOLI RIDUTTORI products are not suitable for Group I and Group II, category 1 applications.
Product Compliance: BONFIGLIOLI RIDUTTORI gear units are designed for potentially explosive atmospheres, limited to categories 2 and 3, complying with ATEX Directive safety requirements.
Verification Procedures:
  • Maximum Torque: Ensure torque does not exceed 200% of rated torque Mn2. For three-phase motors, manage switching torque carefully.
  • Radial Loads: Verify radial forces on shafts are within limits; consider larger units if exceeded.
  • Thrust Loads: Ensure thrust loads are within 20% of overhung load capacity; consult technical service for high loads.
  • Starts per Hour: Ensure starting capability is within limits for high switch duties.
Installation, Use, and Maintenance:
  • Follow the manual for installation, use, and maintenance, available at www.bonfiglioli.com.
  • Maintain ambient temperature between -20°C and +40°C.
  • Ensure motor speed does not exceed 1500 min-1; use suitable motors for inverter applications.
  • Secure gearbox to prevent vibrations; install protective elements if shocks or overloads are expected.
  • Protect nameplate and seal rings during painting.
  • Machine parts to ISO H7 tolerance; use protective paste for key couplings.
Specifications and Procedures:
  • Motor speed with reducer must not exceed 1500 min-1; ensure frequency converter settings prevent overloads.
  • Ensure stable reducer mounting to avoid vibrations; install couplers or limiters for shocks or overloads.
  • Protect identification plate and sealing rings before painting.
  • Components on slow shaft should meet ISO H7 tolerance to avoid damage.
  • Clean and treat contact surfaces with protective products before assembly.
  • For outdoor installations, protect gear unit and motor from weather with guards or casings.
Conditions of Supply:
  • Gear units are supplied configured for specified mounting, tested to specifications, with unpainted surfaces, and equipped with mounting hardware.
  • Shafts are protected during transport and supplied with a lifting lug where applicable.
Paint Specifications:
  • Paint specifications for gearboxes are available from suppliers or dealers.
Construction of ATEX-Specified Equipment:
  • Equipped with service plugs, vent caps, and factory-charged with synthetic lubricant.
  • Standard fluoro elastomer seal rings, no plastic components, operable at specified temperature limits.
  • Temperature indicators supplied with each unit.
Versions and Options:
  • Various gearbox options for zones 21 and 22 (categories 2D and 3D) with surface temperatures below 160°C or 130°C, and zones 1 and 2 (categories 2G and 3G) with temperature classes T3 or T4.
Lubrication:
  • Gear units use oil-bath and splash lubrication; ATEX versions are factory-filled with "long-life" lubricant SHELL OMALA S4 WE 320.
  • Check oil level or fill gearbox as instructed in the manual available on the Bonfiglioli website.
Specifications and Calculations: The document provides calculation procedures for input/output shafts and axial loads, with specific formulas and conditions for functionality. Axial load calculations are based on radial loading values, with guidelines for permissible loads and consultation with technical services if exceeded.
Technical Data and Installation Guidelines: Includes technical data for gearboxes, installation conditions, and guidelines for maximum motor power. Gearbox rating charts assist in selecting appropriate models based on application requirements.
Recommendations: For excessive axial forces, contact Bonfiglioli Riduttori for analysis. Adhere to specified conditions and consult technical services when necessary.
