现行的马氏机构,仅用于传递小质量或低转速场合,这是由槽轮在啮合开始与终止时具有一定数值的角加速度这一固有特点所决定的。随着生产自动化的发展,流水线的应用日益广泛。如将现行的马氏机构用于生产流水线,会产生振动、定位不准以及零件严重磨损等严重缺点。为此,自动化生产迫切需要对现行马氏机构进行革新。参阅国外有关文献后,本文较详细地导出马氏机构的运动学公式,从而引出一种新型的马氏机构。它的特点是啮合开始与终止时槽轮的角加速度为零,以及槽轮的角加速度变化平缓。因而可将这种新型马氏机构直接用于大质量、高转速的生产流水线上。这样就突破了“马氏机构仅用于传递运动,而不能用于传递载荷”的这种传统观念。并为马氏机构更广泛地应用开创了美好的前景。本文对如何将现行的马氏机构进行加工改制,使之成为新型马氏机构提出了自己的看法(本文提供有关计算数据及装配图),并将新型马氏机构用于陶瓷厂生产流水线做了尝试,经试车证明效果良好,基本上消除了流水线上的振动及定位不准等缺点。
The current Markovian mechanism is only used to deliver small masses or low speeds depending on the inherent characteristics of the angular acceleration at which the sheave has a certain value at the start and end of meshing. With the development of production automation, the application of assembly line is more and more widely. Such as the existing Markov institutions for the production line, there will be vibration, positioning errors and serious wear and tear and other serious shortcomings. For this reason, automated production urgently needs to innovate the existing Markov institutions. After referring to relevant foreign literature, this paper derives the kinematic formula of Markovian mechanism in more detail, which leads to a new Markovian mechanism. It is characterized by a zero angular acceleration of sheave at the start and end of meshing, and a gentle change of angular acceleration of sheave. This new Markov mechanism can therefore be used directly in production lines of high quality and speed. This breaks through the traditional notion that “Markov agencies are used only to transmit motion, but not to transmit loads.” And created a bright future for the wider application of Markovian institutions. In this paper, we put forward our own views on how to modernize the Markov machinery and make it a new Markov mechanism (this article provides the calculation data and assembly drawings), and made a new Markov mechanism for the ceramics factory’s production line Attempt, the test car proved effective, basically eliminating the pipeline vibration and positioning errors and other shortcomings.
