The structure of club of 1 pair of teeth and principle explain bolo of common center lathe is worn use drive of bar of the silky luster of mercerized cotton fabrics to satisfy its to machine precision and transmission requirement commonly, and numerical control lathe uses structure of drive of ball guide screw commonly. The double tooth strong drive of article introduction, apply in bolo of numerical control center lathe to wear now, it changed traditional bolo to wear the structural kind of fore-and-aft shift. Double tooth strong drive is to use tooth of nicety inclined tine the structural means with clench the teeth of 2 helical gear, these 2 helical gear at the same time with the tooth clench the teeth, can deliver the principle of axial force according to helical gear, the structure is used in mount of gear of an inclined shaft the helical gear with a helix angle and opposite way of inclined shaft positive drive. Come out from Ⅲ axis 2 drive catenary parts with inclined tine tooth clench the teeth (the positive drive after Ⅲ axis all is) of helical gear drive, the axial that passes Ⅲ axis adjusts, make with inclined tine tooth 2 helical gear of photograph clench the teeth turn to 2 opposite way, achieve gear and tooth thereby the unoccupied place drive of very close to each other between. Data of contrast of the advantage ball guide screw of strong drive of 2 pairs of teeth and double tooth strong drive. By data the analysis is reached, double tooth strong drive compares ball guide screw to have advantage in the application in numerical control machine tool: (Drive of guide screw of 1) traditional ball is higher to environment and maintenance requirement, to assure ball guide screw had defended reach safeguard go to the lavatory to often make the structure of the machine tool more complex, give assemble personnel brings a lot of troublesome; and double tooth strong structure need not consider these, want to assure to lubricated to go only. (Structure of 2) ball guide screw accepts restriction on length, because ball guide screw grows his more,install precision 0.

02 Mm assures hard more, and the deputy to ball guide screw life after out of tolerance of linearity of ball guide screw can produce bar of influence; double tooth the structure is nonexistent these problems, should assure to install precision only for 0.

14 Mm, theoretic lathe bed can grow indefinitely, and the adjustment that Ⅲ axis can pass after gear wears away achieves unoccupied place drive of very close to each other. (The slowdown of strong drive of 3) double tooth is bigger than ball guide screw. It passes reducer casing optimize a design, highest fall speed ratio can be amounted to 97, return the cutting power that can enhance a machine tool and stability at the same time. And ball guide screw accepts structural restriction, ball guide screw falls speed ratio is very low, want to rise fall speed ratio not only its reducer casing complications, and should be chosen big outside the guide screw of quadrature of round, old spiral shell, and the demand that reachs length to defending also rises accordingly. (4) considers from economy, guide screw of ball of excel of double tooth strong structure. What because the machine tool designs the treatment workpiece length of the requirement,reach machine tool structure is different, the ball guide screw that place of every machine tool needs is different, need produces manufacturer to press a blueprint paper to have something made to order, not only the price is high and indent cycle is long, average order cycle is 10 months, the price is 20 thousand yuan about / M.

And major part proper motion machines double tooth strong structure, main bought-in component is inclined tine tooth, order goods cycle is 4 months, at the same time petty gain of guide screw of price comparing ball is made an appointment with 10% .

The place on put together is narrated, the advantage that numerical control center lathe uses double tooth strong structure in practice should compare traditional ball guide screw tall. Club of 3 pairs of teeth is produced in practice install tone and application mediumly (the installation in the assembly of strong structure of 1) double tooth in practice is debugged quick and convenient. Be in in general assembly above all tone gear and tooth when clearance, should make sure meantime is unoccupied place in 0.

In 14 Mm, Ⅲ the axis uses tool trice later, will with inclined tine tooth of 2 helical gear of clench the teeth bilge set loose, by Ⅲ the direction of axial adjustment clearance rotates 2 helical gear make its inclined tine tooth flank and tooth after tooth flank relies on to tighten, 2 helical gear bilge set bilge close, pull down the tool of Ⅲ axis finally, reduce Ⅲ axial the section to eliminate gear and tooth clearance. (After the clearance mix up of strong structure of 2) double tooth, its issue backlash to be able to be achieved in open loop condition 0.

05 Mm less than. Occupy contrast through number, the structural style of double tooth strong drive revealed its economic value and economic benefits. Divide an user at present outside special requirement, heavy-duty center lathe all uses producing numerical control structure of double tooth strong drive, it reduced manufacturing cost to the enterprise not only, and shorten production is periodic, brought economic benefits to the enterprise, be worth extensive promotion and application.
