Description
The present invention is a kind of variable speed drive, is particularly useful for various vehicles, lathe, machinery equipment and the speed reduction gearing of widely used stepless, step change transmission or stable drive ratio between various prime mover and work mechanism.
In the known K-H-V Gear Planet Transmission, have that few tooth is poor, cycloidal-pin wheel and harmonic driving, all be for principle of uniformity, generally all be to constitute by three parts such as central gear, pivoted arm and output links.All have velocity ratio big, characteristics such as be widely used, but can only make the speed reduction gearing of stable drive ratio, can not make stepless, step change transmission device.
" adhering to the transmission type speed changer " that the Vadetec company of the U.S. is developed (" world inventions " magazine 81 years the 3rd phase the 10th page on 13 pages), it is a kind of novel friction stepless gearbox, on the axle that spirals of motion that spirals two parts such as cone roller being installed relatively forms, it seems because velocity ratio or slewing range can not satisfy the big characteristics of drive transmission device requirement such as automobile fully, on output terminal, to increase the device that enlarges slewing range, axial dimension is long in addition, especially the axle that spirals is longer, be again moving link and stressed member, the junction point of two axial lines is imported with regard to wayward, on the output axis, even centering on input, the output axis is made states such as space rotation, this is disadvantageous to the exigent friction stepless gearbox of running accuracy, synchronism to two control ring move toward one another, spiral the axle fatigue, noises etc. all have certain unfavorable factor.
The present invention is intended to overcome the prior art deficiency, comprehensively develops the advantage of these two kinds of mechanisms, and further develops into new height-Tuo pendulum-type K-H-V planetary mechanism, makes this new mechanism can become the retarder transmission of stable drive ratio required in the machinery; The current mechanism that step change transmission and Friction Stepless transmission etc. are taken like a shot.
Review paper of the present invention:
The present invention is a kind of comprehensive improvement invention, specifically be after the structure of the Vadetec company with the U.S. " the adhering to the transmission type speed changer " of being developed is removed half, junction point from the most difficult two axial lines is provided with special synchronous universal coupling, and needed various torques are extracted.The Outside diameter of taper has increased many (increase to produce to interfere with control ring till) significantly like this, and velocity ratio has just enlarged during natural low speed.Rotating the athletic posture of taper (50) in control ring (52), the attitude during with toy gyroscope stall is the same, does the motion of top pendulum cycloid spread.As Fig. 1, its structure is the top pendulum-type K-H-V planetary body of the present invention of having extended out on the basis of conventional K-H-V planetary structure and gyro beat motion phenomenon.
Among Fig. 1 of the present invention, input shaft (16), output shaft (18) and control ring (52) three's coaxial line (20) become the α angle with the axis (22) of the taper of doing planetary motion (50), and two axial lines intersects at the center O of the bulb (58) of synchronous universal coupling.Like this in some the buses on the taper (50), all the time there is a bus to contact when no matter rotating to any position with the inner hole wall of control ring (52), this bus is called Line of contact (51), arbitrfary point on the Line of contact equals the radius R of control ring (52) all the time to the distance of axis (20), be Line of contact parallel to the axis all the time (20), when the support arm (26) of input shaft (16) forced taper (50) to do revolution, the linear velocity on the Line of contact (51) did not have speed difference.The Outside diameter d of taper (50)
MaxValue can be slightly less than or near the inside diameter D (can not equal the control ring inside diameter D) of control ring (52), its relation is roughly, d
MaxRadius γ=RCOS α.Do not produce with the inside diameter D of control ring (52) when taper (50) is done the planetary motion of top pendulum and interfere with near a little interference is arranged, energy freely operate as best.
The microcephaly's of taper (50) a end is to be installed in the bearing (24) on the input shaft (16) of band counterweight (28) band support arm (26) by tapered body axle (54), thus reach constraint α angle guarantee on the Line of contact (51) arbitrfary point and axis (20) equidistantly and equal R.The big end of taper (50) links to each other with output shaft (18) by synchronous universal coupling, with umbrella gear (46,48) transmitting torque.Control ring (52) move axially ratio between the diameter d that is changing arbitrary portion on control ring inside diameter D and taper (50) total length, to reach the purpose of the speed of continuously changing.
Taper (50) is done the planetary motion of top pendulum-type, be to revolve round the sun under the common constraint of central point O of bearing (24) in the support arm (26) on α angle, input shaft (16) and coupling, be locked into one and can not do relative rotation by the steel ball in the automatic pressurization device (rod) (60).Variation along with the moment of torsion on the output shaft (18), the back side ball-and-socket (55) that steel ball (60) acts on press ring (56) and is manufactured on the umbrella gear (46) on the tapered body axle (54) is also corresponding the changing of active force on the inclined-plane separately, and produce small moving axially, so just directly taper (50) and control ring (52) wedging automatically, because control ring (52) and housing (14) have flat key (53) to link can only be moved axially and can not rotate, this just forces the taper (50) of doing revolution to change sense of rotation, formed the planetary motion that promptly will revolve round the sun and force the compound top pendulum-type of doing rotation, its motion state is done complicated top pendulum-type planetary motion just like the toy gyroscope of a stall under controlled condition.
The geometrical center of bulb on the synchronous universal coupling of the present invention (58) is the O point, and it is again the junction point of two axial lines (20), (22).With the O point is the angular bisector that 180 °-α ° is made at the center, torsion pass umbrella gear (46) on Here it is the tapered body axle (54) and the torsion pass umbrella gear (48) two on the output shaft (18) are taken turns the tangent line mutually of pitch cone angle, and the O point also is the common vertex of the pitch cone angle of torsion pass umbrella gear (46,48) two-wheeled.A pair of in addition auxiliary rolling bearing also is selected in the pitch cone angle of two-wheeled near on the garden conical surface (62,64) of center O, that is to say, the garden conical surface (62) that with axis (22) is rotating center is made relative pure rolling on the garden conical surface (64) that with axis (20) is rotating center, so just shared the carrying on the bulb (58) on the coupling widely.Because the pitch cone angle of torsion pass umbrella gear (46,48) two-wheeled is by determining on the angular bisector of 180 °-α °, so the angular velocity on the tapered body axle of time rotational (54) and output shaft (18) two concurrent aceses is equal.Simultaneously the O point also is top pendulum motion of the present invention center, is again centering, carrying, torsion pass center etc., the synchronous universal that it had, and not only torsion pass but also carrying and auxiliary rolling bearing etc. all are the specific functions that is had especially on the coupling of special role of the present invention.
α of the present invention angle is the revolution axis (20) of taper (50) and the angle of rotation axis (22), also be called taper (50) and make the top pivot angle of top pendulum planetary motion, the size of α angle selected generally 7 ° to 20 ° comparatively suitable, concrete is selected as to take all factors into consideration on request.Suppose when a control ring that does not have thickness moves to junction point O place on axis (20), the cutting plane of the control ring on Fig. 3 is crossing with the P point on the Line of contact of installing with the α angle on the taper of placing so, and the perpendicular distance from the P point to axis (22) is exactly the Outside diameter d of taper (50)
MaxThe radius γ of value, the inside diameter D that P point is called temporarily with control ring (52) does not interfere with the approaching transition point that a little interference is arranged, and the position of transition point P on Line of contact is that size with top pivot angle α changes so.So α angle decision P point position, the value of P point decision γ, the low-low gear ratio of γ value decision output.
The inside diameter D of control ring (52) is given, and the diameter d that taper (50) is gone up the arbitrary position is different.When control ring moves axially to diameter d on the corresponding taper, following special circumstances are arranged: work as d
MaxDuring=D, i=0; When d=(D)/2, i=-1; Work as d
Min=0, i=-∞.So total velocity ratio scope in theory is i=0 to-∞.Control ring moves to the N point by the M point, promptly-1 to 0 being deceleration area; Move to the T point by the M point, promptly-1 to-∞ is the raising speed district, but actual velocity ratio is i=-0.02 to about-3.5.If will seek out zero rotating speed output, can install one section at the big end place of taper (50) and have flexible skirt.Velocity ratio formula of the present invention is i=1-(D)/(d).
Among the present invention when when coming transmitting torque, being the Friction Stepless transmission device in the mode of friction between taper (50) and the control ring (52).When taper (50) replaces with the taper gear train of arranging by size, with some ring gear axially spaced-aparts arrange and accordingly with the taper gear train on each gear be in the free idling conditions of normal engagement respectively, when pinning some ring gears with modes such as free wheel devicees, just can realize the step change transmission, can obtain from several grades to the different class more than more than thousand grades, can realize by low speed at a high speed or by at a high speed to the order speed change of low-speed control; Can realize that class is optional, or baffle etc., manual, program control, the automatic speed changing of various maneuverability patterns can be adopted; Can not stop during speed change, do not have and impact, have starting fast, acceleration performance is good, and speed ratio is accurate; It is little also to have slip simultaneously, can be continuously even conversion rate, can slip be controlled at 1 change or 1 change more than, even stepless change also is difficult to be equal to, and do not need characteristics such as automatic pressurization device, as Fig. 7, Fig. 9.
If only make a gear on the taper (50) in the present invention, also only be meshed to substitute control ring (52) with a ring gear, also free wheel device does not pin ring gear, all can be routinely the method for poor, the cycloidal-pin wheel of few tooth, few 1 to 4 tooth of the number of teeth of the gear ratio ring gear of the gear of doing planetary motion is not waited Here it is top pendulum-type K-H-V planetary reducer.
The present invention is in order to enlarge slewing range, and can regard image pattern 1 such device as is a monomer (10), so just can open up a lot of applications to the monomer assembling combination dexterously that ins all sorts of ways.As Fig. 4, shown in Figure 9, exactly two or more monomers (10) combined serial is got up to use.In order to increase output power, transmit the ability of bigger moment of torsion, can use with two or more monomers (10) combination is in parallel, or be combined into parallel connection and add Several combination modes such as series connection, as Fig. 5, shown in Figure 6 be exactly a kind of Friction Stepless device of plural parallel stage flow deviding type, can accomplish powerful output.
The present invention has novel structure, compactness, the principle science; Can be stepless, level, gearing down arranged; Have that velocity ratio is big, slewing range is wide; But ascending, descending speed; Input, output coaxial cable, the practical velocity ratio of general monomer are about between-0.02 to-3.5, and the monomer slewing range allows 1500～3000 rev/mins of direct input speeds or higher about 150.If with more than two during monomer series-connected the use axial dimension not oversize yet, structure is also not too complicated, minimum output speed can reach 1 rev/min or approaching to zero rotating speed, can obtain from several grades to the step change class more than more than thousand grades, the shelves number is the multiplication relationship of each monomer inner cone body gear train gear quantity of being connected.If, one 400 grades top pendulum-type K-H-V planetary automatic speed-changing case has been installed on certain automobile car, automobile from static to the speed that drives to the highest speed, be by from low speed to high speed, or from pressing the level arrangement to the order speed of low speed at a high speed, control its velocity transformation and motor with micro computer, clutches etc. are adjusted to the optimum state, it has starting soon, acceleration performance is good, slip between every grade can be controlled in 10 right sides of turning left, there is speed change steady, rapidly, there are not advantages such as impact, and the gear that the participation speed change is used can be above 18 pairs yet, even with present state-of-the-art fourth gear, five grades of planetary automatic speed-changing casees by comparison, concrete advantage and good effect be significant, be very widely equally as for its application in fields such as lathes.It is contemplated that the variable speed drive of the various particular types under the present invention might produce a tremendous variation.
