Abstract

The focus of this work is a geometric parameter of an asymmetric involute spur gear tooth. Gear strength is influenced by tooth geometry. So, knowledge of tooth geometric is required which will help to improve the strength of a gear tooth. In this article, a data generated from an equations and presented in form of graph for better interpretation of the effect of drive side pressure angle on various parameters like contact ratio, HPSTC radius, load angle, tip thickness, thickness of tooth at pitch circle radius, critical section thickness, bending moment arm height, etc. Parametric analysis of gear tooth gives an idea about how different parameters affect tooth geometry of an asymmetric involute spur gear tooth which is essential for modelling and manufacturing. Parametric analysis helps to calculate optimise drive side pressure angle. It is also predicted or calculates % reduction in bending stress at the root of the tooth without using FEA. It is explained with illustration and results are compared to justify it.
非对称渐开线直齿齿轮齿形参数分析
本工作的重点是非对称渐开线直齿轮齿的几何参数。齿轮强度受齿形的影响。所以,知识的齿几何是必需的,这将有助于提高一个齿轮齿的强度。为了更好地解释驱动侧压力角对传动比、HPSTC半径、载荷角、尖端厚度、节圆半径处齿厚、临界截面厚度、弯矩臂高度等参数的影响,本文从一个方程中生成数据并以图形的形式表示。对非对称渐开线直齿齿轮的齿形进行参数化分析,了解不同参数对其齿形的影响,对齿轮的建模和加工具有重要意义。参数分析有助于计算出最佳的驱动侧压力角。在不使用有限元分析的情况下,还预测或计算了齿根弯曲应力减少的%。用插图说明了这一点,并比较了结果来证明这一点。

期刊介绍: IJPT addresses novel scientific/technological results contributing to advancing powertrain technology, from components/subsystems to system integration/controls. Focus is primarily but not exclusively on ground vehicle applications. IJPT''s perspective is largely inspired by the fact that many innovations in powertrain advancement are only possible due to synergies between mechanical design, mechanisms, mechatronics, controls, networking system integration, etc. The science behind these is characterised by physical phenomena across the range of physics (multiphysics) and scale of motion (multiscale) governing the behaviour of components/subsystems.
