Ship DN260mm Shafting Rolling Intermidiate Bearing
Introduction:
B type gliding intermediate bearing, this type of intermediate bearings is recommended for small and medium vessels in inland water.
Type C is rolling intermediate bearing, this type of intermediate bearings is recommended for medium and large vessels.
Technical Features:
The oil film thickness and film thickness ratio of the intermediate bearing under different rotational speed conditions:
When the rotational speed is low, the oil film thickness of the intermediate bearing is smaller.
As the shaft neck speed increases, the oil film thickness also increases and shows an upward trend.
This is because as the rotational speed of the journal increases, the relative motion speed between
the two lubrication surfaces of the bearing increases, and the dynamic pressure effect of forming a lubricating oil film is enhanced,
which is conducive to the formation of the lubricating oil film, thereby enhancing the bearing capacity of the lubricating oil film in the bearing area and increasing the thickness of the oil film.
