Apparatus with a Rotary Seal Assembly Axially Coincident with a Shaft Tilting Focal Point |
| 摘要 |
An apparatus including a housing, a shaft rotatably extending through the housing, and a rotary seal assembly contained within the housing for providing a seal between the housing and the shaft. The shaft is capable of an amount of tilting within the housing about a tilting focal point which is axially located along the housing at an axial focal point position. The rotary seal assembly is axially located along the housing at an axial rotary seal position. The axial rotary seal position is substantially axially coincident with the axial focal point position. |

1. An apparatus comprising:
(a) a housing defining a housing bore; (b) a shaft rotatably extending through the housing bore, wherein the shaft is capable of an amount of radial deflection within the housing bore and an amount of tilting within the housing bore about a tilting focal point, and wherein the tilting focal point is axially located along the housing at an axial focal point position; and (c) a rotary seal assembly contained within the housing bore for providing a seal between the housing and the shaft, wherein the rotary seal assembly is axially located along the housing at an axial rotary seal position, and wherein the axial rotary seal position is axially coincident with the axial focal point position. |
