1 AND DEIGNED FOR ROLLER The range of sprockets and wheels designed for chains manufactured by our Company provides an all-round solution to the needs of industry in the sector of flexible mechanical transmissions and is the result of a manufacturing process that is designed to achieve the top in terms of technical and quality performance. Our production prograe includes sprockets and wheels designed for chains, produced in compliance with the principles and with the most recent tandards and International Unified tandards: UNI, IO, DIN, ANI, etc. However, the standards define a profile with minimum dimensions and a profile with maximum dimensions for the wheel space for chains and rollers and the actual profile must lie within these values. There is the option of selecting proportioning criteria for the profile, since the tolerances that the tandards leave to the manufacturer's discretion are quite wide. The profiles can be optimised in terms of smooth transmission and the tooth s capacity to support greater stresses. This has led to the systematic development of a series of standardised profiles for which the geometry can be reproduced with great precision by tools designed specifically by computer and the reference profile of which is protected by the Company s knowhow. A valued feature of this optimised profile, which is a characteristic exclusive to, is that of enhancing the polygonal chain wrap-around on the sprocket and on the platewheel, reproducing the motion discontinuity which is achieved even in the case of unfavourable transmission ratios and centre distances. As a result of this has been able to include sprockets with a very low number of teeth in its catalogue and production prograe. Respecting precision with limited machining errors is beneficial, even if the toothed wheel-chain set represents a somewhat basic transmission solution. This precision is assured by the systematic use of CNC machines and technologies developed to minimise the shearing stress and to improve the degree of surface finish. The sprockets and wheels designed for chains included in the catalogue are also manufactured in the version with the Taperlock taper bush piece system particularly favoured in applications that require easy assembly and very precise centring tolerances. Our sales prograe is completed with single and multiple roller chains, and special chains suitable for every industrial application and CHIARA- VALLI Trasmissioni spa is also able to manufacture sprockets and platewheels suitable for chains in a specific execution, produced to drawing any of material and with induction hardening and case-hardening and hardening applied to steel wheels and sprockets. 2
