Description
Technical field
The utility model is related to drilling tool technical field, and in particular to a kind of bearing clearance can compensate for formula helicoid hydraulic motor.
Background technology
With the development of petroleum natural gas exploration, increasing helicoid hydraulic motor is applied to deep-well, ultradeep well etc. and bored
Well operations.The composition bottom hole assemblies such as helicoid hydraulic motor and drill bit, drill collar, are directly drill bit positioned at the bottom of whole drill string
Broken rock power is provided, mechanical rate of penetration can be effectively improved, realize directional inclination function.Helicoid hydraulic motor is main by by-passing valve
Assembly, anti-lost assembly, motor assembly, universal axle assembly, driving-shaft assembly etc. are constituted.Wherein driving-shaft assembly is helicoid hydraulic motor
One of important component, its life-span determines helicoid hydraulic motor overall life, driving-shaft assembly be mainly used in transmission the pressure of the drill, moment of torsion and
Drilling fluid.
Existing screw drill transmission shaft assembly includes power transmission shaft, transmission shaft shell, journal bearing, thrust bearings, described
Power transmission shaft is supported by journal bearing and thrust bearing, and in transmission shaft shell, can be rotated about the axis.Existing helicoid hydraulic motor
Thrust bearing be generally multi-row radical thrust ball bearing, when being dallied in drill bit hanging shaft bottom, be primarily subjected to whole fluid column to
Lower thrust and rotor, universal drive shaft, the weight of power transmission shaft and drill bit；The brill that working condition is applied is born when drill headstock is in shaft bottom
Pressure force.But existing thrust bearings are easily worn and torn in use for some time, the axial gap of thrust bearing increases
Greatly, existing thrust bearings can not carry out self compensation.
Utility model content
The problem of the utility model exists for prior art can compensate for formula helicoid hydraulic motor there is provided a kind of bearing clearance.
The utility model solves the technical scheme that its technical problem used：
A kind of bearing clearance can compensate for formula helicoid hydraulic motor, by driving-shaft assembly, universal axle assembly, motor assembly and by-passing valve
Assembly is constituted, and driving-shaft assembly connects universal axle assembly, and universal axle assembly connects motor assembly, and motor assembly connecting bypass valve is total
Into driving-shaft assembly includes power transmission shaft, cartridge housing and disk spring type thrust bearing, and inner ring and the power transmission shaft of disk spring type thrust bearing are consolidated
Fixed connection, its outer ring is fixedly connected with cartridge housing, and cartridge housing includes upper bearing (metal) shell and the lower bearing being threadedly coupled with upper bearing (metal) shell
Inner bore of step is provided with shell, upper bearing (metal) shell.
Above-mentioned disk spring type thrust bearing includes at least one-level disc spring thrust unit
Anti-lost assembly is also set up between said motor assembly and by-pass valve assembly.
The driving-shaft assembly of the utility model helicoid hydraulic motor uses disk spring type thrust bearing, after thrust bearing wearing, profit
The self compensation in gap is carried out with the pretightning force of disc spring, so as to avoid power transmission shaft axial float；Disc spring can also play buffering drilling
During drill bit be transferred to power transmission shaft vibration effect, extend the service life of thrust bearing, and then improve screw drill
Has the service life and reliability in underground.
