GB/T 14364-2008Sliding intermediate shaft bearing of marine shafting (English PDF)

Foreword

This standard replaces GB/T 14364-1993 "ship shafting sliding intermediate bearing." The standards are compared with the GB/T 14364-1993 The following major technology changes.

--- Modify the scope of "unit pressure of 0.6MPa" to "unit pressure not more than 1.0MPa";

--- Canceled C products;

--- Added Figure 1 position size L2;

--- Increasing the size of the table and the corresponding L2 2;

--- Table 3, an increase of 850 to 1000 series, increasing the size and the corresponding position size L2;

--- Edit "3.5 bearing operating temperature of 65 °C" to "temperature-dependent components 4.6.4 Bearing work. Bearing operating temperature It should not exceed 70 °C, or the oil temperature should not exceed 65 °C... "

1 Scope

This standard specifies the middle sliding bearings (hereinafter referred to as bearing) classification, requirements, test methods, inspection rules, packaging, transport and storage.

This standard is applicable to their linear velocity of 1.5m/s ~ 8m/s, the unit pressure is less than 1.0MPa ship shafting sliding center bearing Design, manufacture and acceptance.
