Description
Technical field
The present invention relates to gearbox technical field, the straight integrated change gear box of specifically a kind of non-planetary structure point.
Background technology
With the development of Numeric Control Technology, especially manufacturing industry, main transmission always exists a universal and serious problem：It holds
The servo motor rotating speed for carrying on a shoulder pole main shaft drives is very high, but output torque is little, and the speed of mainshaft also can adapt to motor speed substantially to be needed
It wants, while can also bear certain large torque and apply needs, then main shaft and the optimal connecting mode of spindle drive motor
Should be：When needing high speed rotation, main shaft can be with motor synchronization action；When main shaft needs large torque to export, motor and master
It can realize that large speed ratio slows down by gear between axis, to improve main shaft output torque.
In the manufacturing process of Current mechanical drive mechanism, often occurs to be limited by the structure of intermediate gear, go out
Now output power is conflicting in speed and strength, the mutual restriction the case where, especially when input speed is very high, when we need
The high speed and large torque of output, the result that often cannot just want are pursued simultaneously！Such case is in current numerical control device
Design with manufacture in it is very universal, in general, now middle-size and small-size servo main motor rotating speed can reach 10000 revs/min of left sides
The right side, mechanical main shaft can also reach 6000-10000 revs/min, if motor is connected directly with main shaft, it is non-can to obtain user
Often satisfied rotating speed output, still, if being directly connected to motor centre does not have speed change link, the torque of main shaft is exactly the defeated of motor
Go out torque, then, torque is too small, and cutting power is very poor！If intermediate use common change gear box, by gear linear velocity,
The influences such as noise, main shaft at most can also obtain 5000 to 6000 revs/min of rotating speed, in this way, lathe cannot meet again it is certain
In the case of high-speed cutting, even so, cost is very big and technological requirement is quite harsh, therefore, seriously restricts current base
Plinth industrial expansion, the present situation are or are unable to that bear's paw shark's fin gets both or the epicyclic gearbox that is produced using west is solved
Certainly this problem, even if in the world, there are no the gear-boxes of a non-planetary structure of use to realize this target！And use row
Star gear-box, has the following disadvantages：
It is complicated, high failure rate.In application process, most users are awe-inspiring, higher failure for epicyclic gearbox
Rate and very low recoverability directly limit its commonly used possibility！The presence of this problem is derived from its inherent structure,
In common mechanical speed change structure, planetary gear structure originally manufacture difficulty is big, complicated, since certain fields need small sky
Between realize large speed ratio deceleration, be principal element existing for this gearbox, still, if applied general medium and small
Type Machine Manufacture industry, stability just seem very insufficient.
It is expensive, substantially raise the manufacturing cost of application product.The product is essentially European brand monopolization, China at present
Market price is very high, serious to restrict domestic pillar industry manufacture level！
Using complexity, debugging difficulty is big, difficult in maintenance.Such gear-box is commonly used in the case of small-power moderate rotation
It is fair, it still, is used in when needing external cooling high-power and high-speed occasion, problem just shows immediately, cold when inflow and outflow
But the equipment can be all burnt when, lubricant medium is inconsistent, to accomplish to pass in and out strict conformance, in theory hardly possible one
It causes, so, this is also this kind of gear-box to the basic reason seldom applied in high-power main transmission at present！Application level is not
1 the percent of sufficient numerically-controlled machine tool total amount.On the other hand, user in use, the external accessories such as oil cooling machine,
Once going wrong, it is possible to lead to serious consequence, be burnt in case of driving member overheat, mean this component report substantially
It is useless！Scrapping for one tens thousand of component, is a no small loss for middle-size and small-size numerically-controlled machine tool, so, general user
It never selects to improve main shaft output state using import epicyclic gearbox.
Because of above-mentioned factor, in current middle-size and small-size numerical control device manufacturing process, nearly all product main transmission output is all
There are high speeds without torque or to have difficult situation of the torque without rotating speed, so, in terms of the objective demand angle in market, design a kind of energy
It enough realizes high-speed cutting and low-speed big cutting takes into account, is reliable and stable, is easy to maintain, cost-effective gear-box gesture is must
Row！
