GB/T 28278.2-2012Plain bearings -- Hydrostatic plain journal bearings without drainage grooves under steady-state conditions -- Part 2: Characteristic values for calculation of oil-lubricated plain journal bearings without drainage grooves (English PDF)

Foreword

GB/T 28278 "under steady-state conditions do not bring back the sliding bearing sump hydrostatic radial sliding bearings" consists of two parts.

--- Part 1. not calculate back to sump oil lubrication Radial sliding bearings;

--- Part 2. Do not bring back the oil tank Lubrication Radial Bearing characteristic values.

This part of GB/T 28278 Part 2.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses the translation method identical with ISO 12168-2.2001 "Under steady-state conditions do not bring back the sliding bearing sump hydrostatic radial

Plain bearings - Part 2. Do not bring back sump oil lubrication radial sliding bearings calculated property values. "

Consistency correspondence with international standards in this section of our standards of reference are as follows.

3 characteristic values

See Figure 1 and Table 1 to 19.

This section gives a characteristic value used to calculate back to the oil tank is not lubricated radial sliding bearings are necessary, these values \u200b\u200bare based on

ISO 12168-1 specified premises and boundary conditions to use when calculating the value can be found from the chart, and explanation of symbols

Calculation example see ISO 12168-1. When designing a radial bearing, the characteristic values \u200b\u200bin Table 1 can be used to optimize the design of the bearing.
