Utility model content
The technical problems to be solved in the utility model is: the Power Drive Unit providing a kind of engineering driller; By optimizing structure design and distribution mode for components, make load diatibution and force-bearing situation more reasonable, be beneficial to the reliability of equipment work, the application life of raising equipment, make that facility compact, good rigidly, output torque are large, cost is low, easy to maintenance, sealing is reliable, improve maintainability and the performance of equipment.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
A Power Drive Unit for engineering driller, comprises hydraulic motor, planetary reducer and sealing fixed axis; It is characterized in that: described hydraulic motor and planetary reducer have four respectively, every platform hydraulic motor connects a planetary reducer, the output shaft of above-mentioned four planetary reducers is connected with the power shaft of speed reducing transmission case by spline, and described power shaft merges the gear ring external toothing of power and a helical teeth involute cylinder gear wheel by pinion; Described sealing fixed axis upper end offers compressed air cell; The sidewall of described compressed air cell offers compressed air inlet, and described sealing fixed axis is provided with revolving support, and outer ring and the output shaft of described revolving support are bolted.
As optimal technical scheme, the utility model additionally uses following technical characteristic:
Further: between reduction box casing and sealing fixed axis, to be provided with packing seal structure, described packing seal structure is made up of sealing ring and lubrication circle.
The advantage that the utility model has and good effect are:
The Power Drive Unit of the engineering driller that utility model proposes is jointly drive a gear wheel by pinion after four motors slow down, force-bearing situation during driver element work is optimized, load diatibution is more reasonable, improve the functional reliability of driver part, especially operating mode is disliked slightly, and it is more outstanding that the engineering field that load is larger shows.The existing form of structure of Power Drive Unit needs to compact conformation, good rigidly, output torque large.
It is simple that actuating unit has structure, and installation and maintenance are convenient, and casing is compact, the feature that trouble point is less.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is upward view of the present utility model.
Wherein: 1, hydraulic motor, 2, planetary reducer, 3, revolving support, 4, packing seal structure, 5, pinion, 6, reduction box casing, 7, sealing fixed axis, 8, gear wheel, 9, output shaft, 10, compressed air cell, 11, compressed air inlet.
Detailed description of the invention
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of Power Drive Unit of engineering driller, comprise hydraulic motor 1, planetary reducer 2, revolving support 3, pinion 5, reduction box casing 6, sealing fixed axis 7, gear wheel 8, output shaft 9 and compressed air cell 10; Described hydraulic motor 1 and planetary reducer 2 have four respectively, every platform hydraulic motor 1 connects a planetary reducer 2, the output shaft 9 of above-mentioned four planetary reducers 2 is connected with the power shaft of speed reducing transmission case by spline, and described power shaft merges the gear ring external toothing of power and a helical teeth involute cylinder gear wheel 8 by pinion 5; Described sealing fixed axis 7 upper end offers compressed air cell 10; The sidewall of described compressed air cell 10 offers compressed air inlet 11, and described sealing fixed axis 7 is provided with revolving support 3, and outer ring and the output shaft 9 of described revolving support 3 are bolted.
Four hydraulic motors 1 of Power Drive Unit are manual variable inclined plunger motor, hydraulic motor 1 inputs reduction box after planetary reducer 2 slows down, the output shaft of four planetary reducers 2 is connected with the power shaft of reduction box by spline, and described power shaft merges power by pinion 5 and reaches middle part one helical teeth involute cylinder gear wheel 8 gear ring external toothing.Thus realizing the revolution that drive shaft realizes drilling tool, governor motor discharge capacity can change the output speed of unit head.Four hydraulic motors 1 have the advantage of self-balancing, and center to center distance is little, and effectively alleviate unit head weight, power is input as asymmetric arrangement.Planetary reducer is standard component, directly can purchase installation according to the gearratio of design and quality requirement.
Output shaft 9 is stressed to be copied (moment of torsion, two-way change compared with large axial force), arrange original paper many (radial direction, cod, air flue of calming the anger, calm the anger and mud rotary sealing), in order to ensure transmission accuracy and rotary sealing precision, adopt the revolving support 3 that simultaneously can bear larger axle, radial load and overturning moment.A kind of employing three organ timbering revolving support standard components.The outer ring of revolving support 3 is connected by bolt with output shaft 9, and inner ring and casing are fixed.
Further: between reduction box casing 6 and sealing fixed axis 7, to be provided with packing seal structure 4, described packing seal structure 4 is made up of sealing ring and lubrication circle.The form of structure of packing seal structure 4 is shaped packing seal, and shaping filler to rely on condiment, and this produces elastic-plastic deformation and blocks fluid leakage under the effect of the mechanical compaction power of end thread hold-down ring.This type combined seal ring is made up of teflon seal and afterburning elastic body, hermetically-sealed construction is composed in series successively by some combined seal rings, lubrication circle and several reverse combination sealing, adds by lubrication circle the frictional force that lubricating grease reduces sealing ring and axle sleeve.It is copper threaded pressure ring and annular gasket that end compresses packing seal, ensures reliably being adjacent to of sealing ring and axle sleeve, provides the reliability of hermetically-sealed construction work.Teflon seal and afterburning elastic body combine, and it is little that the seal of formation has frictional force, can bear dry friction, the wear rate on lip and axle surface is low, can play preload object, and the wearing and tearing of automatic compensation sealing circle, temperature applicable range is wide, and oil resistant is anti-corrosion, and sealing performance is excellent.And, sealing can also be protected by increasing support ring, in case under pressure, being crushed or distortion.The combined seal ring of teflon seal and afterburning elastic body composition can improve sealing effectiveness and application life.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
