BEARING DEVICE AND EXHAUST GAS TURBOCHARGER

摘要

In a bearing device with a first bearing body (9) having a first mounting opening (10) accommodating a first rotation body (8) with a first gap (12) formed between an in wall (14) of the first bearing body (9) and an outer surface (13) of the first rotation body (8), a lubricant duct (11) is provided in the first bearing body (9), so as to form communication path to the first mounting opening (10) by way of an end area of the lubricant duct (11) oriented so as to impart a circumferential velocity component to the lubricant flow into the first gap (12) so as to impart a circumferential velocity component to the lubricant flow into the gap (12).

主权项

1. A bearing device comprising a first bearing body (9) having a first mounting opening (10) accommodating a first rotation body (8) with a first axis of rotation (25), so that a first annular gap (12) is formed between an inner wall (14) of the first bearing body (9) and an outer surface (13) of the first rotation body (8), a lubricant duct (11) with a longitudinal duct axis (21) formed in the first bearing body (9), so as to provide for a communication connection between the first mounting opening (10) via an exit end (20) of the lubricant duct (11) to the first mounting opening (10) for supplying lubricant to the annular first gap (12) via the lubricant duct (11), the exit end of the lubricant duct (11) being oriented tangentially to the annular gap (12) so as to impart a circumferential velocity component to the flaw (v) of the lubricant into the annular gap (12).
