Embodiment Construction

[0022] References in this document to orientations, operating parameters, ranges, lower range limits, and upper range limits are not intended to provide strict boundaries on the scope of the invention, but should be construed to mean "approximately" or "approximately" or "substantially" within the scope of the present invention. within the teachings of the literature, unless expressly stated otherwise.

[0023] The present invention is directed to rotary seal assemblies.

[0024] A rotary seal assembly may be used in any device comprising a housing, a housing bore and a shaft rotatably extending through the housing bore, wherein the shaft is capable of a certain amount of radial deflection within the housing bore and within the housing bore Achieving a certain amount of tilt.

[0025] In some embodiments, the device can be configured to be contained within a borehole. In some embodiments, the device may be a device for drilling a borehole. In some embodiments, the device ma...

Abstract

In an apparatus having a housing, a housing bore, and a shaft rotatably extending through the housing bore, a rotary seal assembly includes a seal carrier retainer in contact with The housing connects and defines a cavity surrounding the shaft; a seal carrier positioned within the cavity of the seal carrier holder, wherein the seal carrier can be positioned relative to The seal carrier holder enables both an amount of radial deflection and tilting, and wherein the seal carrier is retained by the seal carrier holder such that the seal carrier is prevented from moving relative to the seal carrier rotation of the retainer; a rotary shaft seal carried by the seal carrier between the seal carrier and the shaft; and a seal carrier seal, the seal carrier seal Interposed between the seal carrier and the seal carrier retainer.

Description

technical field [0001] The rotary seal assembly is used to accommodate the amount of radial deflection and / or tilt between the housing and the rotatable shaft. Background technique [0002] Apparatus including a rotatable shaft extending through a housing bore may include one or more bearings and one or more rotary seal assemblies. [0003] These bearings may support the shaft within the housing bore and / or transmit forces between the shaft and the housing. [0004] The rotary seal assembly inhibits the transfer of fluid and / or debris between the exterior of the housing and the interior of the housing. [0005] In some such devices, the shaft may be capable of a certain amount of radial deflection within the housing bore and / or a certain amount of tilt within the housing bore. [0006] Radial deflection of the shaft can result in the shaft being out of center with the housing bore due to radial offset of the shaft within the housing bore. This misalignment of the shaft wi...
