Description

Power gear assembly
The present invention relates to a cover power gear assembly,, particularly move back and forth in order to produce the motion of big parts.This device is equipped with at least two covers assembly of rotation mutually, and one of them is a driving component, links together with the basic driver device that it is produced with respect to another assembly rotation.
There are various devices and equipment can make big parts move back and forth for example motion of the platform of lathe or cross slide.These devices include the standard crank mechanism, swing link mechanism, the steering gear of screw and nut type, planetary transmission, the frictional drive of all kinds and structure and their combination; Various air pressure and hydraulic systems of pressing the work of steam-cylinder piston principle; Rotation electric power; Air pressure and the hydraulic system finished by the transmission of gear teeth stripe shape; Also has linear motor, based on the electromagnetic system of iron core and coil principle and the various combinations of these systems.
All above-mentioned systems expose some shortcomings significantly, for example feed rate and displacement and regulate inaccuracy, give forward given earlier and move backward relation etc.The problem of air pressure and hydraulic system goes out the leakage at pressure pipeline and valve, and temperature rise is especially polluted easily at controlled valve place.In addition, the major defect of all systems is obviously that initiatively power unit must turn to and could changes its current institute travel direction at present.Conversion direction is accompanied by tangible mechanical stress and energy loss each time, this be since braking and subsequently with power unit with its on the rotary inertia raising speed that is driven machinery or mechanical organ rotating part that is connected cause to institute's required value.Output and rotary speed are big more, and the speed of hope turns to fast more, and stress that causes and loss are just big more.
Power gear assembly of the present invention can solve the above problems.It comprises the assembly that two covers can rotate mutually, and a cover first driving component is connected with the basic driver device, makes it with respect to other assembly rotation; One cover, second driving component is connected with second drive unit, and second driving component is rotated with respect to first driving component.In addition, first and second driving components among the present invention link to each other with appropriate driving device by the non-slip drive device separately.Furtherly, second power unit among the present invention has an output shaft, links on the output shaft of basic driver device by at least one pair of non-slip drive device, and described a pair of transmission device is by disengageable Clutch Coupling.In a most preferred embodiment, first and second driving components comprise a motion screw and a nut respectively.In this embodiment, nut preferably is connected with second drive unit by a cover transmission device.The guide rod engagement that has a gear to be connected in this cover transmission device with the second power unit output shaft.Described gear is placed on the guide rod movably.Another most preferred embodiment comprises having as the central gear of first driving component with as the epicyclic train that the crown shape of second driving component is taken turns and forms.As what be driven parts is a tooth rest.Furtherly, the basic driver device among the present invention and second drive unit all are connected on same power supply and the control module, its top at least one disengageable clutch that also is connected with.
The objective of the invention is to eliminate the speed commutation problem of the power gear assembly of forming by first and second driving components and they each self-corresponding drive units, simplify big parts and reach the control of motion backward forward, two covers independently active power unit provide the independent control of rotary speed separately of two driving components.When two speed were identical, big parts were transfixion.Any difference of two speed just can produce motion.The direction of motion depends on then that He Zhewei is fast and He Zhewei is slow.Feed the difference of rate direct proportion in the first and second driving component rotary speeies.In any case two assemblies are always with same direction rotation.Direction detects and to remain unchanged, but the direction that big parts feed the relative variation with two driving component rotary speeies changes with speed.These characteristics have reduced the load of drive unit significantly by the moment of inertia.Be applied to more to show its advantage when high output and high operation feed rate.Another object of the present invention is the mechanical shock that reduces when turning to, thereby reduces undesirable mechanical wear.A further object of the invention is that the load of power unit is reduced to minimum, and reduces the starting current of institute's use motor, just reduces the heat load and the power consumption of motor simultaneously.The present invention has also further increased the control range of the big component movement of regulating.Because big parts only just can move when the speed of first and second driving components is unequal, with they separately the absolute value of rotary speed there is no corresponding relation, therefore, big feeding of parts can be regulated very meticulously.Aggressive device, particularly motor can run in the scope of best execution speed, make them that peak efficiency be arranged.This point and foregoing system antithesis, those systems in the end rate of feeding in stage must be a significant slowdown, so that driving motor is operated in beyond the optimal performance range.Above-mentioned whole characteristics of transmission device of the present invention make corresponding driving device dynamic characteristic relatively good, have also reduced power consumption.Two cover driving components have increased reliability of operation by the mechanically contact of the non-slip drive device of various velocity ratios, are particularly adjusting and are keeping big part stationary motionless and meticulous safely more obvious to entering under the predefined situation.Be equipped with the transmission device that feeds sensor suitable as little increment linear transducer given meticulous feeding under the rate, the motion of big parts stopped at feed on the guide rail in advance on the point of design.This advantage makes the actuating unit among the present invention can be comparable with complicated and expensive driver, though what installed among the present invention only is the such simple driver of the accurate asynchronous interconnected cage motor of image scale, from a frequency conversion converter power supply.The complete characteristic and the advantage that have kept the screw and nut transmission in the most preferred embodiment of described power gear assembly particularly relate to the advantage of power aspect the conversion of screw shaft direction.Rigid mechanical between screw and the nut connects the mutual motion of having stipulated them, makes to be placed in appropriate driving device beyond the scope that big parts feed, even might adopt belt drives.No matter be first or second driving component, or motion screw or nut, or central gear or crown wheel all can couple together with the corresponding driving device by for example responding to clutch synchronously by the system electric or operation of electrolysis coupling principle.All can add some devices on two most preferred embodiments, so that finish the rectilinear motion of big parts or rotatablely move.

Referring to Fig. 1, shown in the figure embodiment of the power gear assembly of first and second driving components formed by a motion screw 1 and nut 2.Motion screw 1 is directly connected to by on one first motor 3 and the basic driver device that cover is powered and control module 4 is formed.The output shaft 5 of first motor 3 is coaxial with motion screw 1.2 on nut is directly connected to by on one second motor 7 and second drive unit that cover is powered and control module 4 is formed.Motor 3 and 7 is connected in the corresponding output of power supply and control module 4.The output shaft 6 of second motor 7 is coaxial with nut 2, thereby also coaxial with the output shaft 5 of first motor 3.By the ball bearing support on the base 8,8 of bases are to be slidably mounted on the guiding device 9 to nut 2 with second motor 7, and combine with big parts 10 rigidity.Motion screw 1 is fixed, and only drives big parts 10 in spatial movement by nut 2.Big parts 10 can be represented the platform of lathe, or the loading planker of planer etc.This cover transmission device for fixing, also is with same principle work at nut 2 in the what is called " motion turns to embodiment " by the big parts 10 of motion screw 1 drive.Comprise the separate controlled frequency converter of two covers in described power supply and the control module 4, respectively to motor 3 and 7 power supplies.
When motor 3 and 7 started with same speed, the difference of the rotary speed of motion screw 1 and nut 2 was zero, and therefore big parts 10 remain static.Any variation of power supply and control module 4 output frequencies all can cause the difference of two cover whirligig rotary speeies, i.e. the rotary speed n of motion screw 1 sRotary speed n with nut 2 mPoor, 10 beginnings of big parts are moved towards the higher direction of speed.Cause the speed of displacement to be proportional to rotary speed n sAnd n mPoor.In general, the velocity of displacement of big parts 10 equals the rotary speed n of motion screw 1 sRotary speed n with nut 2 mDifference multiply by the pitch of motion screw 1.Two rotary speed n sAnd n mThe influence that changes can be referring to Fig. 4.At first time period T 0-T 1In, the rotary speed n of motion screw 1 sEqual the rotary speed n of nut 2 m, big parts 10 are transfixion.At time period T 1-T 2In, the rotary speed n of motion screw 1 sGradually strengthen, and the rotary speed n of nut 2 mBut reduce, big parts 10 begin to be moved to the left.At time period T 2-T 3Last stable state point-to-point speed should direct proportion change sums in two rotary speeies.At next time period T 3-T 4In, the speed of big parts 10 reduces gradually, to T 4Moment equals zero, because the rotary speed n of motion this moment screw 1 sRotary speed n with nut 2 mEquate.At next time period T 4-T 5In, the rotary speed n of motion screw 1 sFurther reduce, the rotary speed of nut 2 but increases on the contrary, and big parts 10 are moved right.At time period T 5-T 6In, stable state point-to-point speed direct proportion is in two cover whirligig rotary speed n sAnd n mChange sum.At time period T then 6-T 7In, the point-to-point speed of big parts 10 reduces, and this is because the rotary speed n of motion screw 1 and nut 2 sAnd n mDifference reduce.At time period T 7-T 8In, big parts 10 continue to move to same direction, promptly move right, but speed are very slow just so-called fine finishining speed.At time point T 9On, the rotary speed n of motion screw 1 sRotary speed n with nut 2 mEquate, thereby big parts 10 transfixion again.Change corresponding rotary speed simply and just can control the motion of nut 2 and the big parts 10 that link to each other with it, and can turn.In described embodiment, as long as change the frequency of supply of two covering devices, just can accomplish to change simultaneously as mentioned above two speed, also can only change the speed of one of them.If the speed of two motors 3 and 7 changes simultaneously, make the rate of feeding for only changing the twice of one of them speed.
Be similar to the arrangement of above-mentioned introduction, this most preferred embodiment can be designed to also as shown in Figure 2 that two driving components are fixing arrangement.Motion screw 1 with nut 2 be positioned at the output shaft 5 coaxial ends that are connected of first motor 3, the other end has a bearing 11.Second motor 7 is by non-slip drive device and nut 2 couplings.The output shaft 6 of second motor 7 is connected with guide rod 12, and second bearing 13 is arranged on the free end of guide rod 12.Have first gear 14 on the guide rod 12, it links to each other with the 3rd gear 16 by second gear 15.The 3rd gear 16 and nut 2 are coaxial and be to be rigidly connected.Also can replace the 3rd gear 16 by a gear that directly on the periphery of nut 2, forms.First gear 14 is to be slidably mounted on the guide rod 12, and by one with guide rod 12 on the supporting pin 17 of cannelure 18 be secured on the guide rod 12.Three gears 14,15 and 16 and nut 2 be installed on the fuselage 19, big parts 10 also are fixed on the fuselage.
The ruuning situation of this arrangement is same as described above.Rotary speed n when motion screw 1 and nut 2 sAnd n mIn the time of identical, big parts 10 are transfixion.When these two speed were inequality, nut 2 just moved to either direction along the screw 1 of moving, and was sent to moving of big parts 10 by fuselage 19.In this design, can remove second gear 15, but so, the output shaft 6 of second drive unit must be opposite with output shaft 5 direction of rotation of basic driver device.Principle of the present invention is observed in this arrangement too, because motion screw 1 is identical with the direction of rotation of nut 2.Two cover drive unit rigidity installation permissions are installed in drive unit beyond the one cover controlled mechanism, by suitable transmission device active force are sent on the power gear assembly.Such structure has increased range of operation, and has improved the design of lathe.
In order to improve the control characteristics of the power gear assembly among the present invention, can and then increase some options are installed, as can be seen from Figure 3.Driving component, the arrangement of motion screw 1 and nut 2, they with drive unit motor 3 with 7 be connected and with being connected of power supply and control module 4 all with shown in Figure 2 identical.From another point of view, further assembled the gear train of three pairs of non-slips among this embodiment.First pair of gear train comprised and being installed on the motion screw 1, and it is taken turns with the 4th gear 21 of the 5th gear 22 engagements and another and is installed on the guide rod 12, and it takes turns the 6th gear 23 that is meshed with the 7th gear 24.The 7th gear 24 is connected with the 5th gear 22 by a disengageable first clutch 25.The executing agency 26 of first clutch 25 is connected to power supply and exports on 27 with first control of control module 4.The output gearratio of first pair of gear train equals 1.If first clutch 25 is in attracting state, make the speed of motion screw 1 and nut 2 identical, therefore, big parts 10 are transfixion.Second pair of gear train has similar design.An octadentate wheel 31 is installed on the motion screw 1, and it is taken turns with the 9th gear 32 and is meshed.The tenth gear 33 is to be rigidly connected on the guide rod 12, and it is taken turns with the 11 gear 34 and is meshed.The 11 gear 34 is connected with the 9th gear 32 by second clutch 35.The executing agency 36 of second clutch 35 is connected to power supply and exports on 37 with second control of control module 4.The output gearratio of second pair of gear train is greater than 1, preferably near 1.The design of the 3rd pair of non-slide teeth train is also similar.The 12 gear 41 is installed on the motion screw 1, and it is taken turns with the 13 gear 42 and is meshed.The 14 gear 43 is installed on the guide rod 12, and it is taken turns with the 15 gear 44 and is meshed, and gear 44 is connected with the 13 gear 42 by a disengageable three-clutch 45.The executing agency 46 of three-clutch 45 is connected to power supply and exports on 47 with the 3rd control of control module 4.The output gearratio of the 3rd pair of gear train preferably also approaches 1 less than 1.Second and three-clutch 35,45 big parts 10 are fed when being in attracting state respectively respectively in both direction fine finishining.A clutch but at a time only can be arranged by adhesive, two other all is failure to actuate, and therefore has only a pair of gear train to put into operation.These three pairs of gear trains have accurately been stipulated the relative motion of motion screw 1 and nut 2.These options have further reduced the load of power supply and control module 4.Be in that fine finishining feeds or big parts 10 can stop in drive motor 3 and 7 one when static.
Another most preferred embodiment shown in Figure 5 has comprised a cover planetary gear.Directly link on first drive unit of being formed by first motor 105 and power supply and control module 4 as the central gear 101 of first driving component.The output shaft 111 of central gear 101 and the output shaft of first motor 105 151 are coaxial and directly be connected.As the crown shape of second driving component wheel 102 be connected to by second motor 106 and and second drive unit formed of the same power supply of first drive unit and control module 4 on.The shaft coupling here is directly to be linked on the output shaft 161 of second motor 106 by the output shaft 114 of first gear 14 and form, and these two output shafts 114 and 161 are coaxial.Pinion frame 103 is connected with the output shaft 141 of at least one satellite or planetary gear 104.Usually, include 3 to 5 planetary gears as 104 in the epicyclic train, they are evenly dispersed in along on the periphery of central gear 102, and its output shaft 141 is positioned on the pin of tooth rest 103.Tooth rest 103 is that of epicyclic train is driven parts.In the structure of second most preferred embodiment, two motors 105 and 106 output shaft 151 are different with 161 direction of rotation.If necessary, motor 105 and two output shafts 151 of 106 and 161 transmissions that can form by means of one second gear 15 and with same direction rotation.The output shaft 115 of gear 15 is directly connected on the output shaft 161 of second motor, and then the output shaft 116 of the 3rd gear 16 directly is connected on the output shaft 114 of first gear.Fig. 6 and Fig. 7 arrange like this.Under whole various situations, power supply has comprised independent controlled first and second frequency converters 174 and 175 with control module 4, and the controll block 173 that is applied to two converters.The output of first frequency converter 174 is expressed as power supply and exports 171 with first of control module 4, and it is connected on the work winding of first motor 105; The output of second frequency converter 175 is expressed as power supply and exports 172 with second of control module 4, and it is connected on the work winding of second motor 106.As Fig. 5, central gear 101 and crown shape wheel 102 is arranged with opposite direction rotation in the epicyclic train among Fig. 6 and Fig. 7, it is basically as decelerator.Also be easy to accomplish to make central gear 101 and crown shape wheel 102 with same direction rotation, like this just as speed increaser.In both cases, as presenting an output ratio that freely changes on a large scale between the speed of the centre wheel 101 of input speed and the speed as the tooth rest 103 of the output speed of epicyclic train, it has comprised from the speed V of centre wheel 101 and crown shape wheel 102 cAnd V kValue equates that situation lower tooth wheel carrier 103 be actionless speed up to take turns 101 and 102 the highest in theory possible velocity amplitudes when rotating with equidirectional when centre wheel and crown shape.
