Description
Technical field
The utility model relates to petroleum well logging technology, espespecially a kind of microballoon transmission mechanism.
Background technology
Microsphere logging instrument operationally, needs microballoon pole plate to be close to the borehole wall, and its microballoon transmission mechanism is mainly when microsphere logging instrument works, by the power transmission of motor to backup arm, microballoon pole plate is made to be close to the borehole wall, and when carrying on microsphere logging instrument, draw backup arm in, prevent from meeting card.This just requires that microballoon transmission mechanism must be delivered on backup arm the dynamic high efficiency of motor, has certain shock-resistant ability when the borehole wall is irregular.Because the high pressure of down-hole has a certain impact to transmission mechanism, it is needed to have independent pressure balance component to offset the impact of slurry liquid.
The microballoon transmission mechanism of prior art is made up of component such as direct current generator, anti-reverse bearing, ball screw and push rods.But, in the transmission mechanism of prior art, do not connected by flexible member between motor and screw mandrel; Anti-reverse bearing adopts symmetrical deep groove ball bearing, and can not bear axial force, supporting capacity is low, causes microballoon pole plate to paste the not tight borehole wall; Do not have pressure balance component, transmission is uneven, and stationarity is poor.Due to little time large when microballoon pole plate and borehole wall gap, have impact on motor application life, drive disk assembly easily damages, and causes logging well.
As can be seen here, the microballoon transmission mechanism transmission efficiency of prior art is low, and supporting capacity is low, has impact during work, and reliability is low.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of microballoon transmission mechanism, can improve supporting capacity and transmission efficiency, and transmission is evenly without impacting, and process and assemble is simple, can meet the requirement of instrument during well logging.
In order to reach the utility model object, a kind of microballoon transmission mechanism that the utility model provides, at least comprises: motor 1, rolling bearing 4, turn-screw 5 and drive link 6, also comprise: for connecting the jaw coupling 3 of motor 1 and turn-screw 5.
Further, also comprise: be arranged on the sealing ring 8 on described drive link 6, for the righting to described turn-screw 5.
Further, also comprise: the balance cap 7 being arranged on the top of described turn-screw 5, for reducing the power attenuation of described motor 1.
Further, also comprise: for fixing described motor 1 motor fixing seat 2.
Preferably, described rolling bearing 4 is the asymmetric angular contact ball bearing that described turn-screw 5 place installs, for realizing power transmission.
Preferably, described jaw coupling 3 comprises: two half a couplers of three-jaw, is flexible member in the middle of described two half a couplers.
Compared with prior art, the utility model at least comprises motor 1, rolling bearing 4, turn-screw 5 and drive link 6, also comprises: for connecting the jaw coupling 3 of motor 1 and turn-screw 5.Because the utility model microballoon transmission mechanism is by jaw coupling 3, realize connecting between motor 1 and turn-screw 5, the microballoon pole plate moment can be kept to be close to the borehole wall when logging well, there is supporting capacity high, transmission is evenly without impacting, process and assemble is simple, the feature that transmission efficiency is higher, maintenance cost is low.

Fig. 1 is the structural representation of the utility model microballoon transmission mechanism.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, hereinafter will be described in detail to embodiment of the present utility model by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
Fig. 1 is the structural representation of the utility model microballoon transmission mechanism, and as shown in Figure 1, the utility model at least comprises: motor 1, rolling bearing 4, turn-screw 5 and drive link 6, also comprise: for connecting the jaw coupling 3 of motor 1 and turn-screw 5.
Further, also comprise: be arranged on the sealing ring 8 on drive link 6, sealing ring 8 is one round section joint ring, mainly plays the centralizing function to turn-screw 5, and the motion of turn-screw 5 is kept with one heart.
Further, also comprise: the balance cap 7 being arranged on the top of turn-screw 5, because the part-structure of this turn-screw 5 is in down-hole slurry, after adding balance cap 7, the impact of high-pressure slurry can be offset, reduce the power attenuation of motor 1.
Further, also comprise: for the motor fixing seat 2 of fixed electrical machinery 1.
Preferably, rolling bearing 4 is the asymmetric angular contact ball bearing that turn-screw 5 place installs, for realizing power transmission.Turn-screw 5 place, according to different stressing conditions, has installed asymmetric angular contact ball bearing, has achieved and bear axial force, improve the efficiency of transmission, and rolling bearing 4 is standard component, and interchangeability is high.
Preferably, jaw coupling 3 comprises: two half a couplers of three-jaw, is flexible member in the middle of two half a couplers.This jaw coupling 3 can improve axiality, is applicable to small-power, starts the frequent situation with needing rotating repeatedly.And structure is simple, easy to process, radial dimension is little, easy for installation.
The utility model microballoon transmission mechanism is by jaw coupling 3, realize connecting between motor 1 and turn-screw 5, the microballoon pole plate moment can be kept to be close to the borehole wall when logging well, be provided with supporting capacity high, transmission is evenly without impacting, process and assemble is simple, the feature that transmission efficiency is higher, maintenance cost is low.Needed for this mechanism, installing space is little, and gearratio is stablized, and have employed the combination of turn-screw 5 and rolling bearing 4, improves transmission efficiency, improves its application life, and main parts precision easily ensures, maintenance interchangeability is good.
