CHAIN SPROCKETS FOR ROLLER CHAINS 1
The range of sprockets designed for chains manufactured by our Company provides an all-round solution to the ne- eds of industry in the sector of flexible mechanical tran- smissions and is the result of a manufacturing process that is designed to achieve the top in terms of technical and quality performance.
Our production programme includes sprockets and whe- els designed for chains, produced in compliance with the principles and with the most recent Standards and Interna- tional Unified Standards: UNI, ISO, DIN, ANSI, 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 profi- le must lie within these values.
There is the option of selecting proportioning criteria for the profile, since the tolerances that the Standards 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 compu- ter and the reference profile of which is protected by the Company’s knowhow.
A valued feature of this optimised profile, which is a cha- racteristic exclusive to CHIARAVALLI GROUP SpA, 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 unfa- vourable transmission ratios and centre distances.
As a result of this CHIARAVALLI GROUP SpA has been able to include sprockets with a very low number of teeth in its catalogue and production programme.
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 ma- chines and technologies developed to minimise the she- aring 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 fa- voured in applications that require easy assembly and very precise centring tolerances.
Our sales programme is completed with single and multi- ple roller chains, and special chains suitable for every in- dustrial application and CHIARAVALLI GROUP 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-harde- ning and hardening applied to steel wheels and sprockets.
