Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a full oil film floating bearing with an R outer ring groove and a special-shaped inner groove. Background Art

[0002] The oil filling hole of a full oil film floating bearing is generally a radial cylindrical hole. This type of oil filling hole is prone to instantaneous oil interruption during the oil filling process. In addition, when the external ambient temperature is at room temperature or the lubricating oil has been used for a long time, the fluidity of the lubricating oil will deteriorate. These will cause the oil film in the full oil film floating bearing to fail to form in time, resulting in the direct contact time between the outer diameter of the shaft and the floating bearing hole being too long, which reduces the stability of the equipment. Therefore, a full oil film floating bearing with an R outer ring groove and a special-shaped inner groove is proposed to solve the problems of instantaneous oil interruption in the oil filling hole and the failure of the oil film to form in time.
