Описание (английский):

ISO 10823:2004 gives guidelines for the selection of chain drives, composed of a roller chain and sprockets conformant with ISO 606, for industrial applications. The selection procedures and chain ratings it describes provide for roller chain drives operating under specified conditions with a life expectancy of approximately 15 000 h. Owing to the wide variations in loading characteristics, environmental conditions and achieved maintenance, it is desirable that the supplier of the chains and sprockets be consulted to ensure that the performance of the product meets the requirements specified both by the user and by this International Standard.

Overview

ISO 10823:2004 - "Guidelines for the selection of roller chain drives" - provides practical guidance for selecting roller chain drives (roller chain + sprockets conforming with ISO 606) for industrial applications. The standard defines selection procedures, rating methods and design considerations intended to achieve a typical service life of approximately 15 000 hours under specified conditions. It emphasizes real-world variables (loads, environment, maintenance) and recommends supplier consultation to confirm performance.

Key topics and technical requirements

Scope and intent: Selection guidelines for roller chain drives used on parallel shafts in industrial machinery.

Power and ratings: Basic equations for input power and a corrected power (P_c) that multiplies input power by application and geometry factors to account for dynamic loads and sprocket tooth count.

Application and correction factors: Factor f1 (application factor) for driver/driven characteristics and operating shocks; factor f2 to account for the number of teeth on the small sprocket; guidance to use manufacturer charts where appropriate.

Sprocket and chain sizing:

Recommendations for sprocket tooth counts (good practice: not less than 17 and not more than 114 teeth; small sprockets ≥25 teeth for high speeds or impulse loads).
Selection of chain pitch and whether simplex, duplex or triplex is required (notes give duplex = 1.7× simplex rating, triplex = 2.5×).

Design details:

Chain length and centre-distance calculation procedures.
Chain speed calculation and maximum sprocket centre distance.
Lubrication methods and oil viscosity guidance (Clause 9).
Good-practice layout, chain adjustment, idlers and alignment (Clause 10).

Operating conditions assumed in charts: e.g., uniform operation without frequent shocks, operating temperature –5 °C to +70 °C, correct lubrication and alignment, typical chain length and speed ranges.

Applications and who should use this standard

Mechanical design and power transmission engineers selecting chain drives for conveyors, pumps, fans, mixers, printing machines and similar industrial equipment.

Maintenance engineers specifying replacement chains, sprockets and lubrication regimes.

OEMs and system integrators defining drive layouts and service life expectations.

Chain and sprocket manufacturers advising customers and publishing capacity charts.

Practical uses:

Verify required chain pitch and series for given corrected power and small-sprocket speed.

Determine safe sprocket tooth counts, chain length and centre distance.

Apply application and geometry correction factors to account for shocks, starts and environmental conditions.

ISO 10823 produced by ISO/TC 100 (Chains and chain wheels for power transmission and conveyors).

For reliable performance, ISO 10823 recommends consulting chain/sprocket suppliers and manufacturer capacity charts to match drive selection to actual loading, environment and maintenance practices.
