Description
Technical field of the invention:
The invention belongs to mechanical drive gear reducer technical fields more particularly to a kind of be able to achieve to nibble without the rigidity for exporting gap
Close gearing speed-reducer.
Technical background of the invention:
The main force for the modern mechanical transmission that rigid engagement transmission is.In rigid engagement transmission device, in order to consider heat expansion,
Lubrication and the problems such as mismachining tolerance, must provide certain preset clearance between mesh piece.The cumulative reaction of these preset clearances exists
Output end exactly exports gap, i.e. generation " hysterisis error ", referred to as " return difference " or " lost motion ".Output is driven caused by gap
Error directly affects the transmission accuracy of drive apparatus, brings drawback to the precision drives application such as robot and Precision Machining.How
The output gap for reducing positive drive is always the field that professional person makes great efforts research.
The current means for reducing output gap are to reduce mismachining tolerance aspect to carry out from the accuracy of manufacture is improved mostly.
But rigid engagement is driven preset clearance necessary to itself, must be permanently present, single to eliminate from processing technology,
It should not eliminate.So wanting to realize gapless output, only by the innovative design of drive mechanism, necessary preset clearance
It is enclosed in inside drive mechanism and is not delivered to output block, be possible to realize.The research achievement of this side is very poor so far.
It is extensive in universal speed reducer and precision machinery people's retarder field by the transmission device that Oscillating Tooth Gear Reducer principle designs
It uses.Wherein most typical rolling free gear drive mechanism, (prior art) as shown in Figure 1, is made of three major parts: 1, swash
Wave device J;2, Tooth wheel with changeable teeth (H+R+X);3, firm tooth gear G.The oscillating tooth number of teeth is Zh, the tooth number Z of firm tooth gearg;Zh=Zg±1.Its
Middle shock wave device J is installed with eccentric amount e, outer diameter DjEccentric disc;The tooth curve C of the gear teeth of firm tooth gear G, is oscillating tooth
The envelope curve of constant speed conjugate movement is done under shock wave device J driving;The Tooth wheel with changeable teeth H of rolling free gear transmission, is rolled by one group
The oscillating tooth idler wheel R of transmission, pin shaft X and oscillating tooth carrier the H composition of idler wheel.The both ends of pin shaft X are in the oscillating tooth slot of oscillating tooth carrier H.
When work, shock wave device J driving oscillating tooth idler wheel R is engaged with the gear tooth profile of firm tooth gear G, then is passed to push by pin shaft X and be lived
Braces H realizes retarded motion.
The outstanding technical performance of active-tooth transmission, is demonstrate,proved by the comparative test of domestic and international specialized company and practical application
It is bright.But principle discussed in the academic paper and patent document for the related movable teeth reducer announced and structure are shown, defeated
Out the problem of gap on, the feelings of existing various active-tooth transmissions and traditional gear drive or Cycloidal pin-wheel drive device
Condition is similar.To make up foozle, fever deforms and the needs of lubrication and existing preset clearance, is all to be directly delivered to oscillating tooth
On the output shaft of retarder, so output gap not can avoid.But due to the oscillating tooth in Oscillating Tooth Gear Reducer be can radially from by
Movement, this, which just gives to design by structure, realizes that the defeated transmission of gapless provides possibility.
Task of the invention:
On the basis of Oscillating Tooth Gear Reducer principle, design one kind can retain be driven between mesh piece necessary to it is reserved between
Gap, and it is able to achieve the drive mechanism for allowing these gaps not influence output movement, it creates a kind of qualified without output gap
Precision drive retarder.
Technical solution of the present invention:
The active-tooth transmission of gapless output, by shock wave device (P+Q), Tooth wheel with changeable teeth (R+X+F) and firm tooth gear G tri- are big
Component is constituted, as shown in Figure 2.It is characterized in that, the shock wave device of the active-tooth transmission is by flexible ring Q and eccentric drive
Two component compositions of device P;Tooth wheel with changeable teeth is made of tri- group parts of oscillating tooth carrier F, one group of rolling free gear R and oscillating tooth pin shaft X;Gu
Gear is that the internal tooth that the tooth curve being provided with by ring gear G and thereon is C is constituted.
The structure of shock wave device:
The flexible ring Q (abbreviation Q ring) of shock wave device in the gapless active-tooth transmission, being one can produce elasticity
The thin wall circular of deformation.The outer diameter D of Q ringq=Dj+μ。DjIt is exactly to generate interior permanent tooth G's with envelope principle in Oscillating Tooth Gear Reducer structure
When gear tooth profile curve C, the due theoretical outer diameter of shock wave device.μ is appropriate excessively cooperation;The internal diameter D of Q ringn, it is according to Q ring
Strength demand is determined when work;The eccentricity of Q ring is e2;The width of Q ring generally takes with the oscillating tooth idler wheel contacted with wide.
It is D that the structure of driver P in shock wave device, which is an outer diameter,p, it is installed on the eccentric wheel of input shaft with bearing bearing, it is eccentric
Amount is e1Disk.Driver P outer diameter DpNominal size are as follows: Dp/2=Dn/2-e2.
When the size of transmission device is larger or the driving of more waves, shock wave device can also use two or more round wheel shape drivers
The one-point or multi-point inscribe in Q ring and form.It, can symmetrical placement two circle wheel drives when the oscillating tooth number of teeth and permanent tooth teeth number difference are 2
Dynamic device, as shown in Figure 3a.Shock wave device shape is ellipse at this time, i.e., double wave driving structure is when size is larger or revolving speed is higher
The rigidity of rotating mass equilibrium and enhancing Q ring drive area, can in symmetric position inscribe Q ring, arrange two or two with
On circle wheel shape driver, as shown in Fig. 3 b and Fig. 3 c.
Eliminate mechanism in the output gap of the structure:
Eccentric driver P is inside Q ring around center of circle O1Plane motion is done, as shown in Figure 4.Driver P function is at this time
From the deformation of the ring body of the inside of Q ring driving Q ring, play the role of Oscillating Tooth Gear Reducer shock wave device, and whether is rotated with ring body itself
It is unrelated.Q ring is installed in the space on the inside of whole oscillating tooth idler wheels, and since Q ring is the flexible ring gently excessively cooperated, Q ring passes through
The elasticity tension of itself holds out against whole oscillating tooth idler wheel automatic load sharings in the flank profil of firm tooth gear.Due to elastic Q
Ring is flexible radially, so Q ring can be with permanent tooth flank profil C, the foozle of oscillating tooth idler wheel R, pin shaft X and oscillating tooth slot S
Size and shape automatically.
According to the mechanical characteristic of hin shell member, Q ring becomes " a rigid convex to shape automatically with pressure because of " tight "
Wheel ".Although Q ring can produce micro-deformation on the basis of theoretical off-centre operation, the perimeter of Q ring is forever constant.The power of tightening of Q ring is
It being formed after assembly, this is tightened power and acts on whole oscillating tooths, whether with work, and it is unrelated with magnitude of load;Simultaneously
The flank profil of firm tooth gear, the advancing side of oscillating tooth idler wheel with nibble out the state of side, it is always symmetrical inside retarder.Oscillating tooth rolling
It is also always symmetrical to take turns the power being pushed against in the flank profil of firm tooth gear.It is the internal force between mesh piece that this, which pushes against power, not externally
Export work done, therefore the transmission efficiency of Q ring tightened power and nor affect on retarder.
Oscillating tooth idler wheel R is radially movable in the oscillating tooth slot S being supported on oscillating tooth disk F by oscillating tooth pin shaft X.Oscillating tooth
The number of idler wheel differs 1 with the number of teeth of firm tooth gear, thus oscillating tooth idler wheel and its pin shaft on circumferential position with firm tooth gear
Internal tooth be staggered one by one, as shown in Figure 4.After Q ring is packed into the inside of whole oscillating tooths with certain tightness, tensile force will be whole
Oscillating tooth idler wheel R is pushed against in the flank profil of firm tooth gear, at this time between the oscillating tooth idler wheel and Q ring of the left and right sides and Q ring and permanent tooth
It is all very close to each other between flank profil on gear G.When input shaft rotates counterclockwise, the left side of engaging-in firm tooth gear flank profil is all
Oscillating tooth idler wheel R is pushed against on the flank of tooth of all power transmission sides of flank profil of firm tooth gear, and gap is not present;And nibble out firm tooth gear
The all oscillating tooth idler wheel R ' in right side are then pushed against on the flank of tooth of all non-power transmission side of flank profil of firm tooth gear, and gap is also not present.It is living
Tooth idler wheel engages the movement generated with the flank profil of firm tooth gear, is to push oscillating tooth carrier F to export by oscillating tooth pin shaft X.Right side is all
Oscillating tooth pin shaft X ' is the tension force P in Q circle1', reaction force P when oscillating tooth idler wheel is engaged with the flank profil of firm tooth gear2' be total to
Under same-action, the right side of oscillating tooth slot S ' is pushed against with resultant force P3 ', gapless exists;At the same time, all oscillating tooth pin shaft X on the left side,
Equally with the presence of the tension force P1 of Q ring and firm tooth gear flank profil meshing point reaction force P2, resultant force of the pin shaft X in two power
The left side that oscillating tooth slot S is pushed against under the action of P3, eliminates backlass.No matter driver is positive or rotates backward at this time,
It is entirely direct-drive in intimate contact between each force transmission element, completely eliminates hysterisis error.And it is appreciated in transmission device to mend
Preset clearance δ and δ ' necessary to foozle, heat expansion and receiving oil film still have, but gap delta and δ ' this moment, are all located at
Not by pressure and the side being driven also is not done simultaneously on oscillating tooth slot S and S ', so all output shaft will not be transmitted to by transmission
On, therefore preset clearance is just closed in internal system without exporting.
The rolling movable gear driving device of large speed ratio or small size usually uses oscillating tooth club structure, as shown in Figure 5.It is living
Tooth roller structure is to be combined into one oscillating tooth idler wheel R and oscillating tooth pin shaft X, becomes oscillating tooth roller RX.The middle section of oscillating tooth roller RX with
The engagement of the flank profil of shock wave device and firm tooth gear, both ends are located in the oscillating tooth slot on oscillating tooth carrier, push oscillating tooth carrier movement.On oscillating tooth carrier
There is the bar axially across oscillating tooth carrier, final movement is exported by bar.Oscillating tooth roller structure, is equivalent to oscillating tooth idler wheel
Special case when oscillating tooth idler wheel R is equal with oscillating tooth pin shaft X outer diameter in structure, so it realizes the principle and technology for eliminating output gap
Scheme, it is identical with aforementioned oscillating tooth roller structure.
The invention has the advantages that
The present invention is in structure and mode of transfer force, between completely eliminating between the component that stress engages in positive drive
Gap realizes the gapless output of real meaning.
Due to the effect of tightening of the soft ring of Q on shock wave device, whenever whole oscillating tooths are all to be adjacent in firm tooth gear and oscillating tooth
On the joggleword face of frame, the noise of transmission will not be also reduced because of the impact that moment occurs there are gap.
Since the soft ring under closed state has the characteristic for being able to maintain its perimeter, any one is engaged with oscillating tooth idler wheel
Position stress increase, the trend " flattened " will occur to reduce stress;And at the same time, soft ring is nibbled with other oscillating tooth idler wheels
The small position of stress at conjunction, just generate " heaving " trend and increase pressure, until with the contact point of all oscillating tooth idler wheels simultaneously
Reach stress equalization.Therefore Q ring plays the role of good load.
Highly preferred embodiment of the present invention --- Novel penetrating-rod-type is without output gap teeth-adjustable reducer
The present embodiment is a large speed ratio of the Oscillating Tooth Gear Reducer structure design exported using oscillating tooth roller and bar, small size
Gapless output speed reducer.The embodiment, which is removed, has large carrying capacity, compact-sized, high transmission accuracy, high-efficient low noise
The characteristics of outside, prior characteristic does not have idle running when being output shaft positive decommuntation rotation, be high-precision, high rigidity without outlet chamber
Gap precision drive retarder.
The Novel penetrating-rod-type gapless exports movable tooth transmission reducer, by shock wave device (P+Q), Tooth wheel with changeable teeth (RX+F+W) and consolidates
Gear G composition, as shown in Figure 6.Its shock wave device is made of a flexible ring Q (abbreviation Q ring) and driver P;Oscillating tooth tooth
Wheel is the output bar W composition for being provided with the oscillating tooth carrier F of radial oscillating tooth slot S by oscillating tooth roller RX, and passing axially through oscillating tooth carrier;
On firm tooth gear G, it is provided with the internal tooth that tooth curve is C.
The outer circle of Q ring is tightened in the inside of all oscillating tooth roller RX with certain tightness, makes whole oscillating tooth roller RX tight against solid
In the internal tooth flank profil of gear G.Driver P is an eccentric disc with bearing support.In driver P loading Q ring, eccentric disc
On highest point Q ring inner surface is pushed against with certain tightness.
When input shaft rotation, whole oscillating tooth roller RX are whole internal tooth teeth that the Q ring being tauted is pushed against firm tooth gear G
Gear motion is done on exterior feature.At this point, all oscillating tooth rollers in the left side are the right sides for being pushed against the internal tooth flank profil of firm tooth gear;On the contrary, right
The all oscillating tooth rollers in side are then the left sides for being pushed against the internal tooth flank profil of firm tooth gear.At this time from the oscillating tooth both ends roller RX and oscillating tooth carrier F
On oscillating tooth slot S slot between relationship from the point of view of, since the internal tooth flank profil of firm tooth gear is equivalent to inclined-plane, necessarily whole oscillating tooths are rolled
Stick all pushes the power transmission side of the oscillating tooth slot S on oscillating tooth carrier F to, and gap is stayed in the side of oscillating tooth slot S opposite not power transmission.At this time without
It is positive by shock wave device or rotates backward, is all directly driven between each force transmission element, it is very close to each other, to realize gapless
Slow down and exports.
