Detailed description of the invention
Below in conjunction with Figure of description to numerical control machine tool double-shaft output gear transmission system in the utility modelConcrete structure do to illustrate:
A kind of numerical control machine tool double-shaft output gear transmission system, as depicted in figs. 1 and 2, it comprises defeatedEnter gear combination 01, travelling gear combination 02, the first output gear combination 03 and the second output gear wheelsClose 04; Described input gear combination 01, described travelling gear combination 02, described the first output gear wheelsClose 03 and the axis of described the second output gear combination 04 parallel, and from axially, described input gearCombination 01, described the first output gear combination 03 and described the second output gear combination 04 are around describedTravelling gear combination 02 arranges; Described travelling gear combination 02 comprises and being suitable for and the combination of described input gear01 gear ring being meshed 5, and combine 03, described second with described the first output gear respectively and exportThe first gear 2 that gear combination 04 is meshed and the second gear 3, described gear ring 5, described the first gear2 and described the second gear 3 be coaxially set. In the gear train assembly of the present embodiment, described input toothWheel combination 01 is engaged with described gear ring 5, and described the first gear 2 and described the second gear 3 are respectively with theOne output gear combination 03 and described the second output gear combination 04 engagement (output gear is mounted thereto),The input gear combination 01 being connected with drive motors in the time of operation is rotated, and combines 02 by travelling gearDrive the first output gear combination 03 and the second output gear combination 04 synchronously to rotate, described the first outputGear in gear combination 03 and described the second output gear combination 04 coordinates and realizes twin shaft with feed rackOutput transmission; In addition, adopt the said structure in the present embodiment, can make gear train assembly insideLayout is more tending towards is rationally that inner space effectively utilizes, thereby can effectively reduce gear train assemblyVolume, reduces the requirement of gear train assembly to installing space, is beneficial to pushing away of this gear train assemblyExtensively.
Described input gear combination 01, the first output gear combination 03 and the second output in the present embodimentGear combination 04 adopts common gear assembled structure in prior art, in the present embodiment, its structure is not doneRepeat, propose a kind of novel travelling gear combination 02 below:
Referring to Fig. 3 to Fig. 8, edge on the power transmission shaft 1 of the described travelling gear combination 02 in the present embodimentAxially be provided with successively described the first gear 2, built-up gear and described the second gear 3; Described the first gear2 for being rotatably set in the duplicate gear on described power transmission shaft 1, and it comprises near described built-up gear establishesFirst bevel gear 21 of putting and the first helical gear 22 arranging away from described built-up gear; Described the second toothWheel 3 be also duplicate gear, be fixedly connected with described power transmission shaft 1 by flat key, it comprise close described inThe second bevel gear 31 that built-up gear arranges and the second helical gear 32 arranging away from described built-up gear;Described built-up gear comprises the third hand tap gear 6 that axle sleeve 4, described gear ring 5 and two are oppositely arranged, described inAxle sleeve 4 is rotatably sleeved on described power transmission shaft 1, and described each third hand tap gear 6 is rotatably sleeved onIn the installation shaft extending radially outward 41 of described axle sleeve 4 and with described the first bevel gear 21 and described inThe second bevel gear 31 engages, and described installation shaft 41 ends are fixed with for triconodont described in axial limitingWheel 6 adjustment block 7, described gear ring 5 is set in two third hand tap gear 6 outsides, and with described axle sleeve 4Be fixedly connected with; Described the first bevel gear 21, described the second bevel gear 31 and described third hand tap gear 6The number of teeth and modulus all equate.
Travelling gear combination 02 in the present embodiment adopts above-mentioned structure, and gear train assembly is in operationTime, described input gear combination 01 is rotated and is driven described gear ring 5 to rotate, band when described gear ring 5 rotatesMoving described axle sleeve 4 rotates and then drives two third hand tap gears 6 on described axle sleeve 4 to rotate, then and thenDrive described the first gear 2 and described the second gear 3 to rotate, described the first gear 2 and described secondGear 3 reaches rotation respectively in the first output gear combination 03 and the second output gear combination 04 again.Under practical working situation, because described output gear, feed rack have foozle, cause twin shaftHelical gear on two output shafts of output system is the different reaction forces that are subject to from feed rack,Different reaction forces, through transmitting, finally can reach on two third hand tap gears 6 of built-up gear, and twoIn the used time of doing that is subject to different reaction forces, can there is appropriate rotation in third hand tap gear 6, the first gear 2With the stressed large rotating speed of in the second gear 3 will be slack-off, and the stressed little rotating speed phase ofTo accelerating, until reach new dynamic balance, finally make the rotating speed of two output gear axles form trickleDifference, thereby the feed rack mistake that the existing feed system of mentioning in solution background technology cann't be solvedPoor accumulation causes the problem of the excessive and broken teeth of output gear elastic deformation.
Further, described gear ring 5 is fixedly connected with described axle sleeve 4 by four screws, fixing like thisConnect reliable, in practical operation, also can adopt the screw of more than three or four quantity fixing described inGear 5 and axle sleeve 4; Further, in order to increase system operation reliability, described gear ring 5 and axle sleeve 4Between except screw connect, go back between flat key (not shown) be set, turn round to transmitSquare.
Obviously, above-described embodiment of the present utility model is only by clearly illustrating that the utility model is doneFor example, and be not the restriction to embodiment of the present utility model. Common for affiliated fieldTechnical staff, can also make other multi-form variation or change on the basis of the above descriptionMoving. Here without also giving exhaustive to all embodiments. And these belong to the utility modelThe connotation apparent variation of extending out or variation still belong to protection model of the present utility modelEnclose.
