GB/Z 10062.32-2025 is the Chinese standard "Calculation of load capacity of bevel gears - Part 32: ISO rating system for bevel and hypoid gears - Sample calculation for scuffing load capacity".
Its scope clause reads: This document provides calculation examples of scuffing capacity for different bevel gear designs, in accordance with ISO /T S10300-20.These calculation examples...
The required initial gear geometry data conforms to ISO 23509. The term "bevel gear" in this document refers to spur bevel gears, helical bevel gears, spiral bevel gears, zero-degree bevel gears, and hypoid gears.
Wheel design. If this document describes only one or more (but not all) of the above forms, it will be specifically noted.
The formulas in this document are based on equivalent cylindrical gears and are limited to bevel gears where the contact ratio epsilonvalpha of the equivalent cylindrical gear end faces is less than 2.Calculation results Valid within the range of use factors specified in ISO 10300-1 (see ISO 6336-2).
Furthermore, for the height modification system of the pinion and gear... For bevel gears whose sum of numbers is zero (see ISO 23509), the relationships given in this document are also valid. Its clauses include terms and definitions; symbols; applications.
