1, one of describes in detail: mix the stepless speed-regulating device that uses with magnetic clutch and worm screw.
Use structural assembly 001A; 002A; 006A; 008A illustrates it, right-hand member magnetic clutch (19) is installed in the input (16) with key, magnetic clutch (14) is installed on the inside and outside shell (23), two magnetic clutchs (14), (19) connect with annular tooth embedding (12) between, the outer sheet (18) of wiping is housed in the tooth embedding can rotate with annular tooth embedding, the interior sheet (17) of wiping is contained on internal gear (1) the afterbody spline and can moves and rotate by spline, during brush (15) energising, magnetic clutch (19) produces strong magnetic field the suction of wiping sheet is come, annular tooth embedding (12) is combined as a whole with tooth embedding (11) and rotates with input shaft (16), in generation,, moving internal gear (1) rotated, output shaft (20) also and then rotates synchronously, its output revolutions equals motor input revolution, n
2=n
1, n in the formula
2Be output revolutions, n
1Be the input revolution, it also is the maximum number of revolutions of this device, when brush (15) outage, brush (10) energising, annular embedding (12) is that tooth embedding (11) engagement in one and left side is one and right side tooth embedding (11) disengagement by magnetic clutch (14) adhesive, at this moment internal gear (1) is fixed and can not rotates, return to the state before improving, it only is a retarder, has only single speed output, it also is the minimum revolution of this device, worm screw (8) is installed on the inside and outside shell (23), worm gear (7) left side is installed and is wiped sheet shell (6), the inside and outside sheet (22) of wiping of shell can be along sliding in the shell and rotating, magnetic clutch (13) is installed in internal gear (1) leading portion and is floating, when brush (5) is switched on, it is that one and worm gear rotate synchronously with inside and outside wiping sheet (21) with (22) adhesive that magnetic clutch (13) produces strong magnetic field, the revolution of worm gear is subjected to worm screw controlled by stepless speed regulation motor, for interference not mutually, worm screw can be designed to not self-locking, make three-way or four-start worm, if brush (5) (10) (15) is outage all, then the embedding of brush annular tooth mediates, it is uncontrolled that internal gear (1) is in free state, when input shaft (16) rotates and output shaft (20) revolution is zero, has only height when controlling with magnetic clutch merely, low, 03 kinds of revolutions
Control the purpose of internal gear (1) or (2) with worm and gear with stepless speed regulation motor, the revolution that makes internal gear from low to high or stepless from high to low variation, output shaft (20) obtains stepless revolution output, if the common AC motor of input shaft (16) attaching also can obtain stepless speed-regulating device, and be that speed adjustable range is very wide, torque range is very wide.
Worm gear (7C) is installed on the output shaft (20), and worm screw (8C) is installed on the shell (23), also magnetic clutch can be installed, and its objective is that control output shaft (20) is rotated further, or stop operating synchronously rapidly that there is detailed argumentation in bottom
2. two of detailed description: without magnetic clutch, with the realization of worm and gear control, " A ", " B ", " C ", " D " stepless speed-regulating device are asked for an interview structural assembly 001 merely; 002; 003; 003A; (the 20th page of figure) 004; 004A; 006; 007; 008 is also representing the schematic representation of making speed regulating mechanism control of gear, this is that easy stepless speed-regulating device is installed in a kind of manufacturing simple in structure, at the motor that is connected on the input shaft (16) is that main motor (30) can with general AC/DC motor, but the motor that is contained on the worm screw must adopt stepless speed regulation motor could realize stepless speed-regulating device, because: worm screw is under stepless speed regulation motor drives, worm gear (7) internal gear (1) or external gear (2) are also along with stepless rotation, so output shaft (20) is stepless rotation output, has so just realized stepless speed-regulating device.
When input shaft (16) high speed rotating, internal gear (1) maintains static, and output shaft (20) has only single low speed output, becomes the retarder before improving.Make movable rotating installation worm gear (7) when internal gear (1) and reinforce with splined nut locking, thrust bearing is installed at worm screw (8) two ends, and in the shell of packing into (9), worm screw one end is installed stepless speed regulation motor and realized stepless speed regulation.
When the revolution of worm gear from low to high, during stepless from high to low variation, internal gear (1) also so changes, when internal gear (1) turn to output shaft (20) in the same way the time then output shaft (20) revolution equal two revolution additions, when direction is opposite then output shaft (20) revolution equal two revolutions and subtract each other, and moment of torsion also is the addition and the variation of subtracting each other
The performance of this stepless speed-regulating device is, if improve the revolution of the output shaft (20) of front reduction gear and be 20 change branch, improve the revolution of back with worm and gear control internal gear, change from low to high, suppose to change to the highest 1000 and change the time-division, turn to when identical, then the revolution of output shaft (20) be 20+1000=1020 change branch, during switched in opposite, then 20+ (1000) if=-980 change to divide anti-phase revolution be-20, the revolution of output shaft (20) be 20+ (20)=0 change branch, at this moment range of revolution be zero/minute, the highest input revolution branch.Its three kinds of revolutions are 0 rev/min ,-980 rev/mins, and+1020 rev/mins.
3. three of detailed description: the method that realizes micron order (μ) feeding transmission.
Input shaft (16) is connect the AC frequency conversion stepless speed regulation motor, range of revolution be 45-4500 change branch, speed ratio 1: 100 (ask for an interview Qinghai first machine tool plant * main transmission of H754 Machining centershorizontal)
" A ", " B ", " C ", " D " these four kinds of arrangements for speed regulation all can be connected, parallel connection, and series-parallel connection is used, and output shaft during series connection (20) can be worked as input shaft (16) and be used like that, and various clutches and speed regulating mechanism can be installed, and makes its free speed change
Describe with gear change mechanism with small teeth difference now:
The speed ratio of first order gear change mechanism with small teeth difference is i=100
Second level gear change mechanism with small teeth difference speed ratio is i=100
Simple computation is stated than scope: adopt double stage tandem
I=1/100 * 1/100 *=1/10000 ratio coverage:
Maximum number of revolutions is 4500 rev/mins, and minimum revolution is 45 * 1/100 * 1/100=0.0045 rev/min, so ratio coverage is:
0.0045-4500 rev/min, if be used for the ball screw feeding with 0.0045 rev/min, pitch is 12MM, the then theoretical amount of feed is 0.0045 rev/min, 0.0045 * if 1200 μ=5.4 μ/minute per minute presses 45 changes feedings, the revolution amount of feed is 5.4 ÷ 45=0.12 μ/commentaries on classics, the feeding with high precision amount has only the speed-adjustable motor of employing could realize the feeding of micron (μ) level like this, electrical control is also very high than the complicated cost of common AC motor, China's machine tool technical innovation is difficult to realize, though the producer that has has manufactured and designed economical NC machine tool, because precision is low, the cost height is difficult to large size and promotes.
4. four of detailed description: main motor adopts AC motor, and arrangements for speed regulation adopt stepless series connection to realize the feeding of μ level.
Adopt common AC motor to realize the feeding of highi degree of accuracy micron μ level, it is just passable to increase the one-level arrangements for speed regulation, cost increases several thousand yuan, just can realize the feeding of μ level, simple computation is to establish main motor revolution 1500RPM, three grades of series connection of retarder, and speed ratio is 1/100 * 1/100 * 1/100=1/1000000, calculate 1500 * 1/1000000=0.15 rev/min, establishing feed screw pitch is 12MM=1200 μ
Then 0.151200=1.8 μ/commentaries on classics, if speed ratio is big again, pitch is littler, the workman adopts the feeding of crawl method when the operating electrical machines knob starts, just can realize the feeding of μ level.Revolution 1 μ feeding just.
The present invention designs and really not soly simply just can realize the feeding of V level, because the few tooth of planet, the difference driven wheel is rotated further the frictional resistance by each link, output shaft (20) is slowly stopped, this is these four kinds of arrangements for speed regulation, can not be widely used in lathe, can not be applied to the main cause of fine positioning.The invention solves this difficult problem, the way that solves is such: go up at output shaft (20) and install, when various clutch speed regulating mechanisms use when two arrangements for speed regulation series connection, then output shaft (20) with use like that as input shaft (16), this example has adopted magnetic clutch, worm and gear is done speed regulating mechanism and is done damping mechanism, the synchronous rotational synchronization of output shaft (20) and input shaft (16) is stopped, when input shaft (16) when stopping operating, magnetic clutch on the output shaft (20) shifts to an earlier date several seconds kinds, energising makes the adhesive of behaviour's sheet produce powerful resistance, prevent output shaft (20) to rotate, when input shaft (16) starts, magnetic clutch on the output shaft, leading circuit-breaker, can accurately start synchronously, if adopt twin worm control worm gear, because worm screw (8C) is installed in shell (33) and goes up the axial force that produces the counterforce counteraction worm screw, offset inertial force, with the twin worm control worm gear (7C) of eliminating the gap, because worm gear (7C) firmly is installed in output shaft (20) with key and goes up rotation synchronously, stop synchronously, all the time offset and dragged the inertial force that object produces, prevent to creep, this just requires motor and the motor on the input shaft (16) on the twin worm (8C) to realize automation with PC electrical equipment or numerical control control, twin worm (8C) adopts the three-way or four-start worm of not self-marketing and motor connecting end to adopt steel ball insurance zygote, prevent with input shaft (16) system between interference, the destruction part, twin worm (8C) control system is mainly used in big load rotating component, realizes the feeding of (μ) level.This is two speed-adjustable motors of a kind of usefulness, and one drives input shaft (16), a motor that drives output shaft (20), and two motors make a concerted effort to drive output shaft (20), can increase output torque.
Four, with two axial lines intersect, examples such as parallel gears, various band, chain realize the present invention
More than explanation is to do the also available hourglass worm speed governing of speed regulating mechanism with worm screw, worm gear magnetic clutch, and helical gear drive and magnetic clutch are mixing and making as speed regulating mechanism because they are the staggered gear engagement of two axial lines.Can both be used for above four kinds of transmission devices.Its method is identical with above-mentioned example.
Above-mentioned these erection drawings all can be installed, and parallel cylindrical gears, helical gear, the internal tooth crop rotation speed regulating mechanism of two axial lines is all passable, selects for use cylindrical gears to do the example explanation now.Two cylindrical gears structural assemblies 0011 are the examples of making speed regulating mechanism, also can adopt kind of the clutch of being engaged in conjunction with being used alternatingly, and see 19 pages of driving mechanism charts, and to make speed regulating mechanism also like this for each gear on 39 the hurdle in, and it is ditto described to arrange using method concretely.
The cone gear that two axial lines intersects, spur gear, spiral gear, curved tooth cylindrical gear etc. are made speed regulating mechanism, structural assembly 0012 is to select for use cone gear to make speed regulating mechanism as example, also can use with various clutch mixed and alternates, it is also like this to see in 19 pages of driving mechanism chart 40 hurdles that various gears are made speed regulating mechanism, and the concrete arrangement using method is ditto described.Structural assembly 0011,0012 mix with magnetic clutch install and the same structural assembly 001A of using method, 002A, 006A, 008A etc. similar.
Above-mentioned these speed regulating methods are that external speed-adjustable motor is made speed regulating mechanism, can also outer lace, vee belt, circle adhesive tape, rope, chain, toothed belt etc. do with stepless speed regulation motor that speed regulating mechanism is existing to illustrate it with flute profile band example.As erection drawing 0013, toothed belt (24), gear (25) axle (26) gear (28), wheel (28) endoporus has the meshing formation one of several keyways of six splines and internal gear (1) tail end.
Can be for moving internal gear (1) along with rotation, the same example of its course of action is described.
More than various speed regulating mechanisms and clutch are installed at input end.
Below be various speed regulating mechanisms and clutch to be installed at output terminal, but because installation method is similar, so only use an example (using worm screw) that it is described.
At output shaft (20) the various clutches of various gears can be installed, make damping device, what its purpose prevented that moving object inertia from being produced creeps, this example structural assembly 002A, 003A, going up installation four-start worm (8C) worm gear (7C) at output shaft (20) is that one of various gear are used example, be to utilize object of which movement to axial force that worm screw produced, and the counterforce counteraction that worm screw produced, go up installation magnetic clutch or other clutches at output shaft (20), utilize to wipe the resistance of sheet, offset the inertial force that object of which movement produces and its objective is the raising Location accuracy.
Concrete using method: master's motor input shaft (16) that the stops operating during location, also stop operating and output shaft (20) drags object, although object continues the very little microdisplacement of motion moving displacement by action of inertia, and be motion.The present invention (20) on output shaft has installed worm gear, worm screw, Electric Machine Control, can adopt pc control, electric system is coordinated, control is used, wipe sheet for using, control such as steel ball also is like this, produce powerful resistance, thus offset object when creeping inertial force reach the purpose that improves Location accuracy.
About adopting twin worm control cycloid transmission stepless speed-regulating device, see erection drawing 003A (structural assembly), also be applicable to " A " " C " " D " device, motor (29) is a stepless speed regulation motor, worm screw 8A, 8B rotation in the same way synchronously under the transmission of transmission shaft (26) gear (25) of toothed belt (24) during motor (29) rotation, but two worm threads are not to be that left-hand and dextrad make worm gear " 7 " rotation drive internal gear (1) and output shaft (20) rotation in the same way.
