Description
Technical field
The utility model relates to a kind of thrust-bearing, specifically, is a kind of TPH400 of Siji Saiwa Oil Drilling Equipment Co., Ltd type three cylinder plug formula slurry pump tandem compound type thrust-bearing that is used for, and belongs to the thrust-bearing technical field.
Background technique
In the prior art, plunger mud pump belongs to one of capital equipment of petroleum drilling and mining industry, mainly bears impact axial force from drilling rod as the thrust-bearing in the drilling tool transmission shaft.Be subjected to the restriction of self structure, it is poor that this kind bearing bears the ability of thrust load.Main cause is the roller stressing conditions more complicated when work in the bearing, owing to the complexity of geologic structure in the drilling process and the uncertainty of geological condition, causes the instability of bit force situation, often is subjected to the influence of impulsive load.Uncertain impact force is easy to cause roller cracked too early.Thereby exist not enoughly on traditional thrust bearing, it is indifferent to bear thrust load, in using the helicoid hydraulic motor drilling process, advocates and will be born by the thrust-bearing in the screw drill transmission shaft by the pressure of the drill that the drilling well tubing string is applied on the helicoid hydraulic motor.Bored the influence of layer firmness change during drilling well, drill bit is very unstable in whole drilling process, play up and down always, and instantaneous axial force reaches very high numerical value through regular meeting.So big impact force will all be applied on the thrust-bearing, and will be strong inadequately if thrust-bearing bears the ability of axial impact, just be easy to cracked inefficacy, thereby cause the whole drilling tool can't proper functioning, for drillng operation increases trouble, bring loss.
Summary of the invention
The purpose of this utility model is the problem at above-mentioned existence, and a kind of adaptation TPH400 of Siji Saiwa Oil Drilling Equipment Co., Ltd type three cylinder plug formula slurry pump tandem compound type thrust-bearing is provided.Plunger mud pump to current more and more abominable drilling condition, can effectively improve the working life of helicoid hydraulic motor with tandem compound type thrust-bearing.
The technical solution of the utility model is, a kind of tandem compound type thrust-bearing, keep stand, spacer, cylindrical roller, thrust retainer lid, seat ring, screw to constitute by blowout patche, thrust, it is characterized in that: cylindrical roller (4-1), cylindrical roller (5-1) are installed in the seat hole of thrust maintenance stand (2), with screw (13-2) thrust retainer lid (6) being sleeved on thrust keeps constraining in sidewindering of blowout patche (1) and sidewindering of seat ring (7) on the stand (2); Cylindrical roller (4-2), cylindrical roller (5-2) are installed in the seat hole of thrust maintenance stand (12), with screw (13-1) thrust retainer lid (11) being sleeved on thrust keeps constraining in sidewindering of blowout patche (8) and sidewindering of seat ring (10) on the stand (12); Separate by spacer (3) between blowout patche (1) and the blowout patche (8); Separate by spacer (9) between seat ring (7) and the seat ring (10); Between distance A between cylindrical roller (4-1), cylindrical roller (5-1) and the seat ring (10) and spacer (3) and the seat ring (10) apart from B; Cylindrical roller one end end face is a sphere.
Described a kind of tandem compound type thrust-bearing, thrust keeps stand (2,12) to be provided with uniform cylindrical roller seat hole, cylindrical roller (4-1), cylindrical roller (5-1) are installed in series in thrust keeps the seat hole of stand (2), cylindrical roller (4-2), cylindrical roller (5-2) are installed in series in thrust keeps the seat hole of stand (12), with screw (13-2) thrust retainer lid (6) suit is fixed on thrust and keeps on the stand (2), with screw (13-1) thrust retainer lid (11) suit is fixed on thrust and keeps on the stand (12).
Described a kind of tandem compound type thrust-bearing is not more than 0.005mm apart from the B difference in size between distance A between cylindrical roller (4-1), cylindrical roller (5-1) and the seat ring (10) and spacer (3) and the seat ring (10).
The beneficial effects of the utility model are, the thrust retainer keeps stand and thrust retainer lid to form by thrust, one end end face is that the sphere cylindrical roller constrains in realization rolling on the sidewindering of sidewindering of blowout patche and seat ring by retainer, bear thrust load, under the limited situation of axial dimension, can improve the axial carrying capacity of bearing greatly; Two spacers separate two blowout patches and two seat rings respectively, have realized the series connection of two groups of cylindrical roller thrusts.The utility model makes full use of the axial dimension space, improves axial carrying capacity greatly.Because bearing is inseparable assembly with axle, this assembly structure is compact to design, the utility model is convenient to installation, dismounting and the maintenance of assembly, both alleviated labor intensity, working procedure middle (center) bearing maintainability and load-carrying properties have been guaranteed again, improve the working life of bearing, reduced cost.
