OFFSET SHAFT BEARING ASSEMBLY |
| 摘要 |
An offset shaft bearing assembly includes a drive shaft extending through an outer housing. The drive shaft centerline is at an angle to the centerline of the outer housing. The shaft is coupled to the outer housing by radiused conical bearings which act as thrust and radial bearings. At least one of the radiused conical bearings is offset from the centerline of the outer housing. The radiused conical bearings may include a curved bearing surface, allowing the radiused conical bearings to operate despite angular misalignment. |

1. An offset shaft bearing assembly for a downhole tool comprising:
an outer housing, the outer housing having a housing centerline; a drive shaft, the drive shaft extending through the outer housing, the drive shaft being generally tubular and having a shaft centerline; and two or more radiused conical bearings positioned to couple the drive shaft to the outer housing, at least one radiused conical bearing offset such that the shaft centerline is at an angle to the housing centerline. |
