2021-1-20 · plain textured journal bearings. Tala-Ighil et al [1], examined the texture location influence on the hydrodynamic journal bearing performance. A numerical modeling is used to analyze the cylindrical texture shape effect on the characteristics of a hydro- dynamic journal …
Get Price2014-7-1 · 3.3.2. Journal diameter. In the present work, in order to develop a design reference for selecting the initial diameter of a water-lubricated plain journal bearing under hydrodynamic lubrication, journal diameter (D) used in the numerical analysis covers a wide range of 10–100 mm while the rotational speed (N) of the journal varies from 100 rpm to 5000 rpm.
Get PriceThen numerical analysis of journal bearings with different dimensions is undertaken under different rotational speeds. Based on the analysis, a reference is produced for selecting the initial diameter dimension which is used to design an efficient water-lubricated plain bearing under the given load and rotational speed.
Get PriceThe cylindrical roller bearing shown in Fig. 6.18 has 16 rollers and it is operating under a radial load of 1500 N at a speed of 10 000 rpm. It is lubricated with SAE 30 oil and operating at 100 °C.One would like to know the minimum film thickness and maximum contact pressure. The bearing may be assumed to have the standard properties for steel.
Get PriceAccurate prediction of cavitation is an important feature in hydrodynamic bearing modeling. Especially for thermo-hydrodynamic modeling, it is crucial to use a mass-conservative cavitation algorithm. This paper introduces a new mass-conserving Reynolds cavitation algorithm, which provides fast convergence and easy implementation in finite element models.

Get PriceTypically, mineral-based sulfochlorinated and/or sulfurized oils are used. Plain soluble-oil emulsion solutions are also used with satisfactory results in various gear grinding applications [8]. The productivity of gear finishing by grinding is a function of the time required for rough grinding, finish grinding, and dressing of the grinding wheel.
