A kind of bearing for rotary guide tool and its wear-resistant teeth manufacturing method

Abstract

The invention discloses a bearing for a rotation guide tool and a manufacturing method of wear-resisting teeth thereof. The bearing comprises a bearing inner ring assembly and a bearing outer ring assembly; the bearing inner ring assembly comprises a hexagon socket head screw, a bearing inner ring body, a bearing inner ring end face wear-resisting ring, the wear-resisting tooth A, the wear-resisting tooth D and the wear-resisting tooth F; the bearing outer ring assembly comprises a bearing outer ring end wear-resisting ring, a bearing pedestal, an O-shaped sealing ring, a bearing outer ring outer cylinder body, a rubber ring, a bearing outer ring inner cylinder body, the wear-resisting tooth B, the wear-resisting tooth C and the wear-resisting tooth E. the bearing is reasonable and compactin structure improvement, the problem appearing in the application process of a bearing for a rotation guide tool to the drilling site previously can be solved, the stability and reliability are improved, and the service life is prolonged. All materials are more advanced, the anti-torsion capacity and wear resistance of the bearing for the rotation guide tool can be improved, the underground workof the rotation guide tool is safe and reliable, and the effective implementation of the drilling work of the rotation guide tool can be ensured.

Description

technical field [0001] The invention relates to the field of bearings and its manufacture, in particular to a bearing for a rotary guide tool and a method for manufacturing the wear-resistant teeth thereof. Background technique [0002] Rotary steerable tools are cutting-edge tools for drilling extended-reach wells and horizontal wells in the field of oil and gas exploration, but the working environment is harsh, with the characteristics of high temperature, high pressure, and strong vibration. Bearings for rotary steerable tools are an indispensable key component of rotary steerable tools. They bear axial loads, radial loads and torque loads at the same time. With the vibration of the bottom hole drilling tool, they also need to bear impact loads. [0003] At present, the bearings used in rotary steerable tools are mainly cemented carbide bearings. Compared with ordinary bearings, they have excellent properties such as high hardness, high strength, high wear resistance, and...
