Reliability evaluation and selection of rolling element bearings

A procedure based on graph theory and matrix approach has been developed for the reliability evaluation and election of a rolling element bearing for an application.

The reliability of the bearing is evaluated considering reliability of its elements and their connections.

This is modeled in terms of Reliability Graph of a Rolling Element Bearing.

This graph is represented by an equivalent matrix called Rolling Element Bearing Reliability Permanent Matrix to obtain a matrix function-Reliability Permanent Function.

This function is the characteristic of reliability of the rolling element bearing for the application.

Reliability Index (RI) of the bearing is also defined.

It is a numerical measure of the bearing reliability and is obtained by substituting reliability value of the bearing elements and their connections in the matrix function.

The paper also suggests how to assess these reliability values to obtain the index.

The proposed procedure is useful for designers and practicing engineers for selection of an optimum bearing for a given application.

The methodology is illustrated by means of an example.

Reliability evaluation and selection of rolling element bearings

滾珠軸承的選擇和可靠性評估

內容:

A procedure based on graph theory and matrix approach has been developed for the reliability evaluation and "s?"election of a rolling element bearing for an application.

, 利用圖表理論(圖論)和矩陣模式, 本研究發展了一程序來作為可靠性評估和 滾珠軸承應用上的選擇

The reliability of the bearing is evaluated considering reliability of its elements and their connections.

軸承的可靠度是同時考慮 軸承的元件和連接在上面 軸承桿的可靠度 而評定的.

This is modeled in terms of Reliability Graph of a Rolling Element Bearing.

. 這些是根據滾珠軸承的可靠性的(圖論) 來模擬而來的

This graph is represented by an equivalent matrix called Rolling Element Bearing Reliability Permanent Matrix to obtain a matrix function-Reliability Permanent Function.

這些圖以相當的距陣來表示 稱作滾珠軸承的永久可靠性矩陣函數以獲得可靠性函數 等價矩陣圖表.

This function is the characteristic of reliability of the rolling element bearing for the application.

這些函數 是 以 應用上 滾珠軸承的可靠性 的特徵 來表示.

Reliability Index (RI) of the bearing is also defined.

也定義了 軸承的可靠性指數(RI).

It is a numerical measure of the bearing reliability and is obtained by substituting reliability value of the bearing elements and their connections in the matrix function.

軸承的可靠性 用 量測 數值 表 示 和以 滾珠軸承元件的可靠性的值所取代 和 它們在矩陣函數的關聯所取代 來獲得這量測 數值.

The paper also suggests how to assess these reliability values to obtain the index.

這篇文章也建議如何評定 這些可靠性的值 和 獲得相關的指數..

The proposed procedure is useful for designers and practicing engineers for selection of an optimum bearing for a given application.

所提出的程序對 設計師和從事實務的工程師選選擇最佳化軸承

的應用使有用的.

The methodology is illustrated by means of an example.

這個方法 是用範例 所展示.
