Zupčanici - Cilindrični evolventni zupčanici i zupčasti parovi - Pojmovi i geometrija

Naslov na engleskom jeziku

Gears - Cylindrical involute gears and gear pairs - Concepts and geometry

Područje primjene

Ovaj međunarodni standard specificira geometrijske pojmove i parametre za cilindrične zupčanike s evolventnim helikoidnim bokovima zuba. Modifikacije boka su uključene. Ovaj standard također obuhvata pojmove i parametre za cilindrične parove zupčanika s paralelnim osama i konstatnim kinematskim prijenosnim odnosom. Zupčanik i spregnuti zupčanik u tim parovima zupčanika imaju isti osnovni profil.

Područje primjene na engleskom jeziku

This International Standard specifies the geometric concepts and parameters for cylindrical gears with involute helicoid tooth flanks. Flank modifications are included. It also covers the concepts and parameters for cylindrical gear pairs with parallel axes and a constant gear ratio, which consist of cylindrical gears according to it. Gear and mating gear in these gear pairs have the same basic rack tooth profile. The equations given are not restricted to the pressure angle,α P = 20°. The standard is structured as follows. ⎯ Listing of symbols and nomenclature for a unique description of gears and gear pairs (see Clause 3). ⎯ Equations and explanations of the relevant values for defining a cylindrical gear and its tooth system. The equations for determination of the nominal values for zero-deviation gear description parameters are stated for radial tooth dimensions (gear tooth heights), the distance between flanks of the same hand, the distance between flanks of opposite hand, as well as the tooth flank characterizing parameters (see Clause 4). ⎯ Equations and explanations of the relevant values for defining cylindrical gear pairs. The equations for the essential parameters characterizing the engagement conditions of the unloaded gear pair are listed (see Clause 5). ⎯ Equations and suggestions for desired flank modifications (see Clause 6). ⎯ Concepts and recommendations needed for a unique geometrical definition of the intended results from manufacture (Clause 7). ⎯ Equations for determination of the nominal values or the limiting values for the most used inspection methods for tooth thickness (see Annex A).
