克林贝格锥齿轮副中鼓形量的研究

Study on Drum—Shaped Size for Bevel Gear of Klingelnberg Type

克林贝格制(Klingelnberg)锥齿轮因采用连续切削并可以进行硬齿而刮削,因此生产效率和承载高,同时它的鼓形齿接触特色,避免了对角接触,改善了润滑状况,足锥齿轮发展的主要方向之一。但至今为止,鼓形量的大小均靠近似公式来估算,其结果是否合理得在实际应用中才能得知。现采用的计算机模拟加工和啮合,使设计人员可以事先在计算机上全方位地观察、测量到任意截面的鼓形量,为充分发挥这种锥齿轮副的优势提供了有效的手段。

The spiral bevel gear of Klingelnberg type is one of future versions since it can cut continually and its hard gear-face could be scraped with higher production efficiency and better load-bearance capa- bility, diagonal contact is avoided and lubrication is improved by the drum shape contacting profile. How- ever, the drum-shaped size is calculated approximately up to now, the rationality of drum-shaped size could only be known through practical application. In this paper, the authors describe an approach of computer simulated manufacturing and meshing, which could help the designers to observe and measure the drum-shaped size on any gear profile thoroughly via a computer, providing a valuable means to devel- op the merits and application for spiral bevel gears of this type.
