Description
Technical field
The utility model belongs to the gear reduction unit technical field, particularly relates to a kind of drill top-drive mechanical reduction gear.
Background technology
At present, TDS (being called for short the top drives) has substituted the operating type of traditional rotating disk/kelly bar, greatly having improved the operating efficiency and the operational security of oil and gas well drilling, is the equipment of present high standard and highly difficult oil and gas well drilling operation indispensability.Under other hoisting power of ad eundem, the requirement of the core capabilities of top drive apparatus is: output torque is big, the output speed scope is big, volume is little, in light weight, reliability and durability, long working life.Therefore, pushing up the type selecting and the connected mode between gear-box and the drilling motor of driving gear reduction unit structure, drilling motor is the key factor that core capabilities is driven on the decision top.
Existing top is driven and is adopted multi-form top to drive the gear reduction machine.Drive with the most frequently used 500API tonne of all kinds of tops that rise ability indescribably and to be example, gear reduction rate is generally about 10: 1, and maximum (top) speed is between 180-220RMP, and max. output torque is 33,000-43,000 foot. between the pound.The top that has is driven and has been reached big output torque performance, has but sacrificed the top and has driven little, the lightweight performance of volume; And other tops are driven the output cantilevered fashion of utilizing the drilling motor axle and directly are used as driving gear shaft and use, realized pushing up and driven little, the lightweight performance of volume, motor bearings directly bears the axial force and the radial load of big alternation, cause rubbing partially in the motor bearings storehouse, bearing life is short, exists the top to drive technological deficiencies such as reliability and durability inadequately, that working life is short.
Summary of the invention
The technical problem of the utility model for existing in the solution known technology, and a kind of drill top-drive mechanical reduction gear is provided.
The purpose of this utility model provides that a kind of compact conformation, output torque are big, the output speed scope is big, long working life, safe and reliable drill top-drive mechanical reduction gear.
The utility model is taked following technical scheme:
The drill top-drive mechanical reduction gear, comprise gear box cover and gear housing, gear box cover and gear housing are formed the top and are driven gear reduction box, be characterized in: the output axle head that is installed in drilling motor on the gear box cover is by connecting shaft mechanism and driving gear shaft connecting shaft, driving gear shaft is installed in the gear-box by duplex bearing, driving gear shaft is given master gear by gear drive, and the master gear fixed conveyor is driven main shaft in the top.
The utility model can also adopt following technical measures:
Described drill top-drive mechanical reduction gear is characterized in: driving gear shaft is given the composite teeth wheel shaft by gear drive, and the composite teeth wheel shaft is given master gear by gear drive.
Described drill top-drive mechanical reduction gear is characterized in: master gear and top are driven main shaft and are connected into by bolt and alignment pin and are fixed as one.
Described drill top-drive mechanical reduction gear is characterized in: drilling motor output axle head is processed with public spline, and by involute spline and driving gear shaft connecting shaft.
Described drill top-drive mechanical reduction gear is characterized in: driving gear shaft is installed in the gear-box by spherical self-aligning bearing and cylindrical bearing.
Advantage that the utlity model has and good effect:
The drill top-drive mechanical reduction gear is owing to adopted the utility model brand-new technology scheme, in gear drive, be not subjected to axial force and radial load in the drilling motor gear drive, reduced the requirement of motor bearings, drilling motor can the more high-revolving motor of type selecting, and, can accomplish littler at volume with drilling motor under the power; Meanwhile, this structure design has overcome drilling motor bearing storehouse eccentric wear and short problem of motor bearings life-span; Because driving gear shaft is directly taken root in gear housing and gear box cover by spherical self-aligning bearing and cylindrical bearing, overall gear reduction box structure is more reasonable, so the bearing life on gears engaged precision and the gear shaft more can be guaranteed again; Owing to adopt gear transmission structure of the present utility model, the core capabilities that drive on 500API tonne of top that rises ability has indescribably reached: 48,000 feet of maximum (top) speed 220RPM, max. output torque. pound, volume minimum, weight are the lightest.So, the utlity model has that compact conformation, output torque are big, the output speed scope is big, long working life, advantage such as safe and reliable, promote the top significantly and driven the overall operation performance.
Description of drawings
Fig. 1 is the utility model drill top-drive mechanical reduction gear structural representation.
Among the figure, main shaft, 10-involute spline are driven in 1-drilling motor, 2-gear box cover, 3-gear housing, 4-driving gear shaft, the spherical self-aligning bearing of 5-, 6-cylindrical bearing, 7-composite teeth wheel shaft, 8-master gear, 9-top.
The specific embodiment
For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
The drill top-drive mechanical reduction gear is mainly driven main shaft 9 and is formed by drilling motor 1, gear box cover 2, gear housing 3, driving gear shaft 4, spherical self-aligning bearing 5, cylindrical bearing 6, composite teeth wheel shaft 7, master gear 8, top.Drilling motor 1 is installed on the gear box cover 2, gear box cover 2 and gear housing 3 are formed the top and are driven gear reduction box, the output axle head of drilling motor 1 is processed with public spline, and by involute spline 10 modes and driving gear shaft 4 realization connecting shafts, driving gear shaft 4 is installed in the gear-box by spherical self-aligning bearing 5 and cylindrical bearing 6, driving gear shaft 4 is given composite teeth wheel shaft 7 by gear drive, and composite teeth wheel shaft 7 is given master gear 8 by gear drive.Master gear 8 and top are driven main shaft 9 and are connected into one by bolt and alignment pin.
The drill top-drive mechanical reduction gear is double reduction, compact conformation.Because involute spline connecting shaft mode has preferably advantages such as axially aligning ability, full-depth tooth mesh, transfer torque is big, this gear transmission structure has guaranteed that drilling motor 1 is not subjected to axial force and radial load, provides desirable working environment to motor.Drive in the gear reduction unit structure on top of the present utility model, adopt involute spline connecting shaft mode, adopt driving gear shaft that separate bearings supports, adopted energy than higher pot motor, improve power of motor and keep motor volume little, improve gear reduction rate to 16: 1, be applicable to the higher drill top-drive deceleration device of energy density of oil and gas well drilling operation.Present embodiment has that compact conformation, output torque are big, the output speed scope is big, long working life, advantage such as safe and reliable, can promote the top significantly and drive the overall operation performance.
