Abstract

The invention disclosed a undermine sealing and righting thrust bearing system which consists of shell and bearing bush. The shell is round and the bearing bush is installed into the shell with both sharing the same central point. Between the shell and the bearing bush, there is upper transverse bearing, thrust bearing and lower transverse bearing. At the top of the upper transverse bearing and the bottom of the lower transverse bearing, the dynamic sealing components are equipped which can bear the load from the axial and the radial directions and achieve the righting purpose, especially under various load changing and complex working conditions undermine. The bearing system is an independent system which can be used jointly with features of simple installation and maintenance.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a sealing, straightening and thrust bearing system for downhole tools. Background technique [0002] Downhole tools can provide a variety of power in petroleum geological drilling operations, including rotary and axial power. Thereby achieving the purpose of breaking the rock formation. Therefore, downhole tools will bear axial and radial loads. At the same time, most downhole tools are driven by fluid, which will inevitably generate fluid pressure to act on the tool to form a load. In order to ensure the normal operation of the tool and have sufficient working life, the above-mentioned various loads are borne by the bearing system. Therefore, the downhole tool bearing system is a very important component. [0003] At present, the bearing system of downhole tools adopts axial and radial bearings respectively, and most of them adopt open structure. Even sealing also adopts th...
