Abstract
The utility model discloses a four point contact series type thrust ball bearing, compising a shaft ring (1), a steel ball (2), and a seat ring (3). The steel ball (2) is installed between the shaft ring (1) and the seat ring (3); the whole bearing formed by 10 groups of steel balls and 11 groups of shaft rings by means of the series type is installed in the seat ring. Because of the utility model adopting the full ball bearing structure of the series-type assembly without a holder, the utility model can realize the four point contact, so that the utility model is provided with the larger contacting angle and the bearing of the drill body can bear the larger axial and radial loading force in order to extend the service life of the bearing. The utility model can meet the use requirement for the internal deep well and the drill tool of the well drill of the shaft well; can enhance the efficiency of the drill well; can shorten the period of the drill well; and can reduce the cost of the drill well. The utility model can create the advantage condition for the development of the drill well technology in national petroleum industry such as the positioning well and the following well, etc.
Description
Technical field:
The utility model relates to the part or the annex of bearing, and a kind of drilling tool contacts the series type thrust ball bearings with 4.
Background technique:
As the helicoid hydraulic motor in the mud motor in the petroleum machinery, the life-span of the bearing direct relation cartridge that it is used.During cartridge work, bearing bears the effect of huge hydraulic load and drill bit drilling rod deadweight power.These power promptly have axial force, and certain footpath load is also arranged, and make formerly often to wear and tear with bearing, so its working life is shorter.
Because the used bearing of helicoid hydraulic motor at the underground work inclement condition, adds the drag effect of mud, abrasive wear is serious; The bearing structure of available technology adopting band retainer, though the bearing integral structural behaviour is good, its retainer hardness is low, in abrasive wear, retainer quick abrasion and at first destroying, and then influence the bearing proper functioning.
Summary of the invention:
In order to solve the defective that exists as mentioned above, the purpose of this utility model provides a kind of drilling tool and contacts the series type thrust ball bearings with 4, bearing is selected be not with for use the structural type of the full dress ball bearing of retainer, make it to bear bigger axial and radial load, thereby prolong the working life that drilling tool is used bearing.
In order to realize the foregoing invention purpose, the utility model by the following technical solutions:
Described drilling tool is made up of blowout patche, steel ball and seat ring with 4 contact thrust-bearings.The steel ball device in the middle of blowout patche and seat ring, a whole set of bearing by 10 groups of steel balls and 11 groups of blowout patche tandem arrangements in seat ring.
Owing to adopted technological scheme as mentioned above, the utlity model has following good effect:
Drilling tool contacts the series type thrust ball bearings with 4, because it has adopted not the structural type with the full dress ball bearing of retainer, and adopt 10 groups of steel balls and 11 groups of inner rings to be connected in series the mode that is contained in the seat ring, 4 contacts have been realized, has bigger wrapping angle simultaneously, therefore its drilling tool bearing can bear the bigger radial load power that axially reaches, thereby prolongs the working life that drilling tool is used bearing.Satisfy the usage requirement of domestic deep-well, straight well well drilling tool, improved drilling efficiency, shortened drilling period, reduced drilling cost; For the directional well in the China Petroleum, created advantageous conditions from the development of drilling technologies such as formula well.
Description of drawings:
Fig. 1 is that drilling tool assembles the overall structure schematic representation with 4 contact series type thrust ball bearings.
As shown in fig. 1: 1-blowout patche, 2-steel ball, 3-seat ring.
Embodiment:
As shown in fig. 1: described drilling tool is made up of blowout patche (1), steel ball (2) and seat ring (3) with 4 contact series type thrust ball bearings.Steel ball (2) device is middle at blowout patche (1) and seat ring (3), and a whole set of bearing is made up of 10 groups of steel balls and 11 groups of blowout patches, and the structural type device that adopts the series connection of steel ball and blowout patche is in seat ring.Because it has adopted not the structural type with the full dress ball bearing of retainer, its drilling tool bearing can bear bigger axially and radial load power, thereby prolong the working life of drilling tool with bearing.Satisfy the usage requirement of domestic deep-well, straight well well drilling tool, improved drilling efficiency, shortened drilling period, reduced drilling cost; For the directional well in the China Petroleum, created advantageous conditions from the development of drilling technologies such as formula well.
