Problems solved by technology

[0002] The standard thrust bearing is installed in the frequency vibration screw drilling tool used for drilling or downhole accident treatment. In the high frequency vibration, this kind of bearing is damaged first, mainly in the bracket damage, retaining ring deformation, roller wear, Displacement and damage to other parts, the damage of the bearing greatly increases the construction cost and prolongs the construction period, and the standard thrust bearing does not have the ability to conduct hydraulic oil, which reduces the life of other parts during work

Embodiment Construction

[0016] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0017] Such as figure 1 Shown is a anti-frequency shock single-flow valve bearing, including retaining ring 1, outer retainer A2, inner retainer A3, outer support frame 4, inner support frame 5, outer retainer B6, inner retainer B7 and rollers 8. The retaining ring 1 is a ring structure with a rectangular section. The outer retainer A2 and the inner retainer A3 are both ring...

Abstract

The invention discloses a check valve bearing with a function of preventing frequency vibration. The check valve bearing comprises a check ring, an outer protecting ring A, an inner protecting ring A,an outer support frame, an inner support frame, an outer protecting ring B, an inner protecting ring B and a pin roller. With the application of the check valve bearing with the function of preventing frequency vibration, the service life of a frequency vibration screw drill can be prolonged obviously, production efficiency is remarkably improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of oilfield drilling or oil-water well accident treatment equipment, in particular to a frequency-vibration-proof single-flow valve bearing. Background technique [0002] The standard thrust bearing is installed in the frequency vibration screw drilling tool used for drilling or downhole accident treatment. In the high frequency vibration, this kind of bearing is damaged first, mainly in the bracket damage, retaining ring deformation, roller wear, Displacement and damage to other parts. The damage of the bearing greatly increases the construction cost and prolongs the construction period. Moreover, the standard thrust bearing does not have the ability to conduct hydraulic oil, which reduces the life of other parts during work. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to address the deficiencies in the current technology and provide an anti-frequency vibra...
