Description
Technical field
The invention belongs to mechanical transmission fields, the transmission being widely used between two axis of spatial intersecting, movement can be subtracted
The retarded motion of speed or speedup, most commonly crossed axis angle Σ=90 degree, trace are dispersed throughout among various all kinds of machineries, there is heavy type
Power transmission is also commonly used for the precision indexing transmission of machine-tool and precision instrument.
Background technology
Worm and Worm Gear Driving is very extensive in application in machine equipments, and major advantage is stable drive, vibratory impulse very little,
Noise is very low, simple and compact for structure, and transmission speed ratio is big, and a reduction ratio is generally 5~70, and maximum is up to hundreds of.
Worm geared major defect is：The force of sliding friction of worm screw thread and worm gear thread side is very in transmission process
Greatly, fast fever, temperature rise are caused, energy consumption is big, efficiency is low and causes the basic reason of Worm and Worm Gear Driving failure.In order to protect
The advantages of staying worm-drive and its shortcoming can be overcome, in recent decades, scroll techniques are applied to Worm and Worm Gear Driving by many people
In, there is polytype ball worn worm-drive mode, country is also granted by more than ten patent rights of inventor.
In the multinomial kind of drive proposed, most merit attention or shape track groove is identical with existing worm gear pair
Ball worm gear pair, it is characterized in that the outer rim of worm and wormwheel is both provided with helicla flute, the normal section of slot is single circular arc, double circles
Arc, straight wide slot（Also have claim it is trapezoidal）, worm screw shape has cylinder, also has anchor ring, and envelope mode has single envelope, also has double-contracting network.Together
The helicla flute sectional dimension of one secondary worm and wormwheel is identical, and notch aligns both during assembling, forms multi-detector pipe, is covered in pipe
Ball, the two groove top are distributed in ball center both sides, and worm screw is engaged by ball with worm gear, due to helical flank when worm screw rotates
Pushing effect, drive ball rotary rolling, when ball rotates in helicla flute, axial movement component necessarily worm gear is driven to do
The rolling engaged transmission of worm and wormwheel is realized in rotary motion in this way, and principle has points of resemblance with ball screw assembly, mesh
Though preceding without matured product, feasibility is very high, and chance of success is very big, and existing worm and wormwheel process equipment can also meet need substantially
It will.
Current key issue be the circulating reflux mode of ball there are more problems, lack practicability.Therefore, some are special
Though profit has announced the more than ten years to more than 20 years, input is not practical yet so far, and there are no such commodity sellings in market.
Several art solutions announced listed here are analyzed, discussion wherein ball-recirculation reflux type
Shortcoming and problem, this be also the present invention propose when directly facing background technology.
1. notification number：CN1403726A patent of invention ball worm gearing units
2. notification number：A kind of rolling ball worm gear transmission pair of CN102338195A patents of invention
3. notification number：CN2107567U utility model ball worns
4. notification number：CN1039090A patent of invention Worm drive with double-wrapped annular-surface balls
2. being cycled 1. two patents are all balls in worm gear, the two ball is all in worm wheel helical slot and two side cover plates
Half-round race slot and worm gear in axial hole composition passage inner circulating reflux, unlike the 1. item worm gear both sides end
Lid shape is two and half circles, and the section of circle is spill half slot, and quantity and worm gear spiral shell are radially divided into the semicircle annular groove of whole circle
The equal half slot of spin slot number, and corresponded during assembling, worm gear both sides are then smooth half circles of two convexs, are among top surface
There are two rows of axial holes in helicla flute, worm gear both sides, and outer ring is through hole, and inner ring is half-round cross hole, and explanatory note inner ring is raceway hole, figure
Shape then clearly shows that outer ring is raceway hole.2. item both sides end cap be disc, a side plane of disk also is provided with semi-circular groove, snail
The ball-recirculation through hole of wheel is a row（Big part）It is or two rows of（Small-sized worm gear）, worm gear two sides itself also set up radially semicircle
Channel slot.
The technical solution of above-mentioned two file has a disadvantage that：
First, processing and manufacturing is difficult, and production cost is high.Worm gear both sides and end cap are all using half-arc groove processing time consuming, technique
Property it is not so good, particularly file 1. in end cap, shape is special, and is thin shell piece, also needed in production be equipped with special process dress
Standby, production cost is high.The two requires that end cap radial direction track groove outer end is alignd with worm wheel helical notch, axial in inner end and worm gear
For raceway through hole to just, however after end cap covers, these slot ends and axial raceway through hole are invisible, slightly inclined one during assembling
Point can all cause ball to pass in and out obstacle.Equally, 2. worm gear both sides and end cap have radial radiation shape semicircle track groove, two halves to file
The shaped position error of circular groove centainly may require that very tight, and slightly deviation or when assembling slightly misplaces, and notch is unjustified, not into just
Circular hole will cause ball flow obstacle or even can not flow.The also requirement of axial passage bore center and worm gear center parallel,
However there is a helical angle at worm wheel helical groove center and worm gear center, therefore according to document design both sides hole slot certainly on not.
2nd, usage range is strictly limited.The technical solution of file 1. is more by the axial length increase for making worm gear, then adds
Upper orthodrome end cap so that the existing worm gear of overall structure volume ratio increases very much, and application range can be affected.The side of file 2.
Disc end cap is only applicable to the circular arc zanjon raceway worm gear of this document setting in case（This circular arc zanjon raceway diameter and ball
Identical, groove depth is more than ball bearing radius, and opening is less than ball diameter）.It is not suitable for having the ball worn snail of feature described in this case
Wheel set, because his disc end cap edge can only be reached at ball maximum gauge, it is impossible to be deep into worm spiral trench bottom, nothing
Method guiding ball-recirculation reflux.
3. 4. file is all the scheme that ball cycles in worm screw, also all come with some shortcomings part, such as：3. file
Some attachmentes are also added in worm screw inner cavity, and ball circulation passages are excessively complicated, and transmission efficiency is adversely affected, and produce and process
Amount increase also needs to increase the fitted position of worm screw diameter and one end.
For the first in the ball-recirculation mode of file 4. from ball screw assembly, ball-screw and nut are that full circle connects
It touches, and there are 3~5 row balls to carry simultaneously, the stand under load ball number proportion of reduction is seldom by ball change rail, to lead screw pair
Bearing capacity influences very little, and the centrifugal force suffered by the ball on worm screw is unfavorable for becoming rail movement, this and ball-screw just phase
Instead, it is therefore necessary to reduce and become rail angle of inclination, increase becomes rail length, and the helicla flute on worm gear is very short, is caused due to becoming rail
The reduction of bearing capacity can't neglect, be recycled back to for second pearl i.e. cannula type will caused by bearing capacity loss than the first also
Greatly, this is worm screw designer scheme beyond affordability.The third endless form, that is, keyed ball-returning device seems theoretically preferable, but
Worm screw will be divided into worm set and worm screw two pieces, and the increase of worm screw diameter is larger, and the rigidity of worm shaft is bad, the position of worm set and key
Put fixation not yet in effect.
Also some technical solutions are very high to the working speed of worm screw（Generally all in more than 1000r/min）Pay attention to not enough, rolling
The reliability of pearl shuttling movement, safety risks are larger, and also some design technologies are bad, some can not even be fabricated.
The existing patent of all balls circulating reflux in enveloping worm, all has ignored a material facts：Enveloping worm
The radius at helicla flute to worm screw center is that both ends are big, intermediate small, therefore the linear velocity that ball moves in slot is intermediate slow, both ends
Soon.It is covered with ball before work in helicla flute, worm screw is present with this phenomenon when rotating：The pervious ball in midpoint is more moved along speed
Degree is faster, if front is unobstructed, the distance between ball is also more bigger forward；Conversely, because midpoint ball translational speed is most
Slowly, also should be that translational speed is faster in the backward after midpoint, but the stop for having front ball cannot move forward, therefore necessarily after appearance
Half section of ball is close to squeeze, and causes to can not achieve pure rolling friction between worm screw-ball-worm gear, and inevitable association slip rubs
It wipes, so as to increase energy consumption, reduces transmission efficiency.
