5 PRODUCT DESCRIPTION The helical gearboxes Series RD feature a one-piece cast housing complete with inner support to accommodate 2 or 3 gear stages into the same casing. Manufactured to latest ISO engineering design specifications the housing is checked by computer-aided structural analysis for deflection and stress distribution. Significant strains caused by the effects of torque and external loads do not deflect the monolithic ribwork of the housing, which significantly improves the integrity of the sealed surfaces. The helical gearboxes, Series RD are manufactured in B3 base mounted configuration; they can be easily converted to B5 flange mounting by fitting of the appropriate additional adaptor flange onto the footed body. Single-setup machining on state-of-the-art CNC production lines, the most recent calculation techniques and process controls give superior operational reliability, maximum output torques, high overhung and thrust load capacity, and long working life-time.

12 ELECTRONIC CATALOGUE - 3D-MODELS - 2D-DRAWINGS Modularity and flexibility have been leading the design of Varvel products since The gearbox-kit concept was carried out allowing anyone to assemble the unit in a few minutes with standard tooling. This feature provides the highest flexibility to Varvel s distributors and resellers who - thanks to a limited kit selection - are able to immediately configure the required product. VARSIZE selection programme, available from our site allows a friendly sizing of Varvel product range. 2D/3D Drawings A guided selection allows 2D/3D models to be downloaded for the most popular CAD systems. Guided selection This service returns a list of applicable product configurations upon a given sequence of application parameters (power, output torque, rpm, service factor etc.); a PDF data sheet featuring performance data and dimensional drawings is generated for each configuration, as well as the 3D model and 2D drawings

16 SERVICE FACTORS SERVICE FACTOR of the gearbox Service factor SF1.0 is meant as typical of 8 hours/day operation, with uniform load, starts/ stops lower than 60 per hour and ambient temperature between 60 and 95 F. The ratio between gearbox maximum output torque M 2 of each reduction ratio - listed in gearbox RD ratings, pages 10 to 16 - and application torque M (app) states the service factor to be bigger than the Application factors listed below.

42 SUMMARY OF OPERATION AND MAINTENANCE INSTRUCTIONS Variable speed and reduction gearboxes are not part of the field of application of the Machinery Directive, art.1(2), and they must not be put into service until the machinery into which they are to be incorporated, has been declared in conformity with the provision of art. 4(2), annex II(B) of Machinery Directives 98/37/CEE/ and for Italy only, of DL 459/ Installation Check if the unit to be installed, is properly selected to perform the required function and that its mounting position complies with the order. The nameplate reports such information. Check mounting stability to ensure the unit runs without vibrations or overloads. Running The unit may be connected for clockwise or counter-clockwise rotation. The unit must be stopped as soon as defective running or unexpected noise occur, remove the faulty part or return the unit to the factory for checking. If the faulty part is not replaced, other parts can also be affected, causing more severe damage and making the identification of initial cause more difficult. Maintenance Although the units are no-load run tested in the factory before despatch, it is recommended not to run them at maximum load for the first running hours to allow the proper running in. The gearboxes are delivered already filled with long-life synthetic oil and, in case of replacement or topping, do not mix with mineral lubricants. Handling When hoisting, use relevant housing locations or eyebolts if provided, or foot or flange holes. Never hoist on any moving part. Painting Carefully protect oil seals, coupling faces and shafts when units are re-painted. Long-term storage For storage longer than 3 months, apply antioxidants onto shafts and machined surfaces, and protective grease on oil seal lips. Product s Environmental Management In conformity with Environmental Certification ISO 14001, we recommend the following to dispose of our products: - scraped components of the units to be delivered to authorized centres for metal object collection; - oils and lubricants drained from the units to be delivered to Exhausted Oil Unions; - packages (pallets, carton boxes, paper, plastic, etc,) to lead into regeneration/recycling circuits as far as possible, by delivering separate waste classes to authorized companies.
