本文基于实验和理论研究,提供了锥齿轮和准双曲面齿轮磨损的计算方法[7]。这种计算方法是闪温法。
本文件中的公式旨在建立统一可接受的方法,用于计算钢制直齿轮、螺旋(斜)齿轮、螺旋锥齿轮、零齿轮和准双曲面齿轮的抗擦伤性。它们同样适用于锥形深度和均匀深度的齿。在下文中,术语“锥齿轮”是指所有这些齿轮类型;如果不是这种情况,则识别特定的形式。
在本文发表时,还没有基于积分温度法的锥齿轮和准双曲面齿轮的擦伤载荷能力的计算方法。
本文中的公式基于虚拟圆柱齿轮,并仅限于虚拟圆柱齿轮横向接触比ε v α<2的锥齿轮。结果在ISO 10300规定的应用因子范围内有效?1(参见ISO 6336?2)。此外,给定的关系式适用于小齿轮和车轮的轮廓变速系数之和为零的锥齿轮(参见ISO 23509)。
This document provides a calculation method for bevel and hypoid gears regarding scuffing based on experimental and theoretical investigation[7]. This calculation method is a flash temperature method.
The formulae in this document are intended to establish uniformly acceptable methods for calculating scuffing resistance of straight, helical (skew), spiral bevel, Zerol and hypoid gears made of steel. They are applicable equally to tapered depth and uniform depth teeth. Hereinafter, the term “bevel gear” refers to all of these gear types; if not the case, the specific forms are identified.
A calculation method of the scuffing load capacity of bevel and hypoid gears based on an integral temperature method is not available when this document is published.
The formulae in this document are based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of εvα < 2. The results are valid within the range of the applied factors as specified in ISO 10300?1 (see ISO 6336?2). Additionally, the given relations are valid for bevel gears of which the sum of profile shift coefficients of pinion and wheel is zero (see ISO 23509).
