Description

A kind of harmonic gear transmission device that is used for the oil drilling TRAJECTORY CONTROL
Technical field:
The utility model relates to a kind of harmonic gear transmission device that is used for the oil drilling TRAJECTORY CONTROL, belongs to petroleum machinery power drive mechanism design field.
Background technology:
A kind of elastic deformation by middle flexible member that harmonic drive is that modern age, new development was got up realizes moving or the general name of powerdriven transmission device.The deformation process of middle flexural member is the harmonic wave of a symmetry basically, difference by instructions for use, harmonic drive can be divided into different patterns, mainly contain: Harmonic Gears, harmonic wave worm drive, harmonic wave frictional drive, harmonic wave buncher and harmonic wave shaft coupling etc., wherein being most widely used with Harmonic Gears.
In order to save the oil development cost and to improve oil production rate, those are subjected to the oil field of geographic restriction or development late stage, usually realize oil-gas mining by exploitation ultradeep well, directional well, multi-branched well, extended reach well and length apart from complicated wells such as horizontal wells, thereby make the well of labyrinth be on the increase.In directional well, ultradeep well, extended reach well, ultra-thin oil-reservoir water horizontal well, long drilling process, must adopt control Technology for Borehole Trajectory and stepless adjustable hole trajectory control instrument to realize apart from horizontal well, multi-branched well.In stepless adjustable hole trajectory control instrument, biasing mechanism is that the interaction by two eccentric hoops realizes, the combination rotation of eccentric hoop can reach the purpose of drilling well deflecting.The rotary power of eccentric hoop is directly provided by auger spindle, but the auger spindle rotary speed is too high, and eccentric hoop then is to rotate with lower speed, therefore just needs to design a reducing gear and underspeeds.Because common reducing gear is bulky, the underground work transmission efficiency is low, supporting capacity is low, simultaneously can not under the condition of confined space and oil bath, transmit motion, and the gear reduction that being difficult to bear exceedingly odious environment such as HTHP has Yin Ci Now far can not satisfy the requirement of stepless adjustable hole trajectory control instrument, demand studying the reducing gear that a kind of volume is little, gearratio is big, supporting capacity is big urgently, to adapt to the requirement with the TRAJECTORY CONTROL instrument of various wells of creeping into of present various complex structural wells.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of harmonic gear transmission device that is used for the oil drilling TRAJECTORY CONTROL, makes it have the advantages that volume is little, in light weight, gearratio is big, supporting capacity is big, transmission efficiency is high, Shi uses Shou Ming Long.
The utility model is to realize above-mentioned purpose by following technical solution.
In a kind of structure that is used for the harmonic gear transmission device of oil drilling TRAJECTORY CONTROL, be provided with rigid gear, flexible gear, bearing, wave producer, hollow shaft; Rigid gear has ring gear, and flexible gear has external toothing; Wave producer is an oval cam; Wave producer is installed on the hollow shaft, at wave producer and flexible gear Zhi Inter bearing is installed; Outer ring at flexible gear is equipped with rigid gear; Few 2 of the number of teeth of flexible gear specific rigidity gear; Flexible gear adopts 30 chromium manganese silicon materials to process.
The utility model has following beneficial effect compared with prior art:
1, harmonic gear transmission device volume of the present utility model is little, in light weight, can be applicable to the down-hole narrow space, gear range is big, do not have and impact, noiselessness, stable drive, can be for a long time stable work under exceedingly odious conditions such as the environment of down-hole oil bath and HTHP, the transmission efficiency height, safe and reliable.
2, harmonic gear transmission device of the present utility model is easy for installation, and supporting capacity is big, adopts the high flexbile gear material of fatigue resistance, has improved the application life of device greatly.
Description of drawings:
Fig. 1 is an assembly structure schematic diagram of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
In the drawings: 1. rigid gear, 2. flexible gear, 3. bearing, 4. wave producer, 5. hollow shaft.
The specific embodiment:
A kind of harmonic gear transmission device that is used for the oil drilling TRAJECTORY CONTROL of the utility model is made up of rigid gear 1, flexible gear 2, bearing 3, wave producer 4, hollow shaft 5; Rigid gear 1 has ring gear, is equivalent to the centre wheel in the planetary system; Flexible gear 2 has external toothing, is equivalent to planetary gear, can produce distortion; Wave producer 4 is an oval cam, is equivalent to planet carrier; Wave producer 4 is installed on the hollow shaft 5, with flexible gear 2 Zhi Inter bearing 3 is installed at wave producer 4; In the outer ring of flexible gear 2 rigid gear 1 is installed; Few 2 of the number of teeth of flexible gear 2 specific rigidity gears 1; Flexible gear 2 adopts fatigue resistance height, corrosion resistant 30 chromium manganese silicon materials to process.
Wave producer 4 is an input, and rigid gear 1 is an output, can realize slowing down the gearratio that can be fixed.Flexible gear 2 is for producing the thin-walled gear of big elastic deformation, and its diameter of bore is slightly less than the length overall of wave producer 4.When wave producer 4 rotates under the drive of hollow shaft 5, drive flexible gear 2 rotations, flexible gear 2 produces distortion under the effect of wave producer 4 elliptic cams, the gear teeth of the flexible gear of locating at wave producer 4 major axis two ends 2 and the gear teeth of rigid gear 1 mesh fully, and the gear teeth of the flexible gear of locating at the minor axis two ends 2 and the gear teeth of rigid gear 1 are thrown off fully; In the interval of the major axis of wave producer 4 and minor axis, the gear teeth of the gear teeth of flexible gear 2 and rigid gear 1 have is in half engagement, is called engaging-in; The engagement of then withdrawing from gradually that has is in half disengaged condition, is called and nibbles out; Because the continuous rotation of wave producer 4, make engaging-in, mesh, nibble out, throw off fully these four kinds of situations circulation change successively fully, because few 2 of the number of teeth of flexible gear 2 specific rigidity gears 1, so when wave producer 4 rotates a week, flexible gear 2 turns over the angle of two teeth round about, thereby has realized big speed reducing ratio.
Wave producer 4 adopts the double wave structure, because double wave structure stable drive, supporting capacity is big, can satisfy the down-hole complex working condition.Because flexbile gear the time can produce distortion in work, so flexible gear 2 adopts fatigue resistance height, corrosion resistant 30 chromium manganese silicon materials to process, simultaneously because the operating characteristic of flexible gear 2 also must adopt special processing technology.
