Description
本發明為一種零間隙齒輪之傳動機構，尤指一種利用複數個壓簧以推動副齒輪之零間隙齒輪的傳動機構。 The invention relates to a transmission mechanism of a zero clearance gear, in particular to a transmission mechanism that utilizes a plurality of compression springs to push the zero clearance gear of the auxiliary gear.
對於較大的機械結構，例如混凝土拌合廠內的大攪拌桶、需要很大的扭力之工具機、要讓轉盤旋轉的吊車或挖土機，通常會增設一台減速機以降低馬達的轉速，讓大尺寸的變頻馬達之出力變大，產生大馬力而使力量放大，然後用小齒輪去帶動更大的齒輪。而兵工廠所建造的砲臺，亦需要旋轉帶動砲臺下的大齒輪。如果在齒輪之間產生了間隙，砲口瞄準時就會使砲臺或砲身晃動，造成瞄不準目標。因此需要消除齒輪之間的間隙，達到零間隙的標準方可達到瞄準的精度及擊中目標。 For larger mechanical structures, such as large mixing drums in concrete mixing plants, machine tools that require a lot of torque, cranes or excavators that need to rotate the turntable, a reducer is usually added to reduce the speed of the motor. The output of the large-size variable frequency motor is increased, the high horsepower is generated and the power is amplified, and then the pinion gear is used to drive the larger gear. The turret built by the arsenal also needs to rotate to drive the large gear under the turret. If there is a gap between the gears, the muzzle will cause the turret or the gun body to sway, causing the target to be inaccurate. Therefore, it is necessary to eliminate the gap between the gears, and the standard of zero clearance can achieve the aiming accuracy and hit the target.
在習知技藝中，小齒輪是包括主齒輪及副齒輪，並利用一個扭簧的二端分別卡住主齒輪及副齒輪上的開孔中，使小齒輪不管是在正轉或反轉時，都能緊緊咬著大齒輪，在組裝小齒輪的時候，需要給它施加液壓的壓力，是先將扭簧轉緊，再將正、副齒輪相扣合，當配合的 齒輪進入主齒輪與副齒輪中間的齒縫時，會擠壓副齒輪往逆時針方向旋轉，被拉開的扭簧就會有回轉的力量使副齒輪往順時針方向旋轉，而與主齒輪共同咬緊被夾在中間的配合齒輪，利用夾緊的力量使其傳動時就無間隙，正、副齒輪產生錯動，把配合齒輪抱著左、右旋轉，亦即利用扭簧的扭力以產生反向的力量，是猶如剪刀的力量。 In the prior art, the pinion gear includes a main gear and a sub-gear, and the two ends of one torsion spring are respectively engaged in the openings in the main gear and the sub-gear, so that the pinion gear is in forward or reverse rotation. You can bite the big gear tightly. When assembling the pinion, you need to apply hydraulic pressure to it. First, tighten the torsion spring, then fasten the positive and negative gears. When the gear enters the tooth gap between the main gear and the auxiliary gear, the auxiliary pin gear rotates counterclockwise, and the pulled torsion spring will have the turning force to rotate the auxiliary gear clockwise, and together with the main gear The meshing gear is clamped in the middle, and the clamping force is used to make the transmission without gap. The positive and the secondary gears are dislocated, and the matching gear is rotated by the left and right, that is, the torsion force of the torsion spring is used to generate The power of the opposite is like the power of scissors.
請參閱第一圖，顯示出另一種市面上的無間隙齒輪傳動機構，其中主齒輪11及副齒輪12各設有內錐形斜面13及外錐形斜面14，並利用二根螺絲15鎖緊使主齒輪11與副齒輪12互相靠近，並造成副齒輪12的內孔16之內徑ID縮小而夾緊軸心，以及主齒輪11的外緣17擴張、外徑放大，主齒輪11與副齒輪12即卡合在一起，副齒輪12的內徑與減速機的軸心(未示出)卡合在一起並互相咬合，當軸心旋轉的時候，副齒輪12就會跟著一起旋轉。 Referring to the first figure, another commercially available gapless gear transmission mechanism is shown in which the main gear 11 and the sub-gear 12 are each provided with an inner tapered bevel 13 and an outer tapered bevel 14 and locked by two screws 15 The main gear 11 and the sub-gear 12 are brought close to each other, and the inner diameter ID of the inner hole 16 of the sub-gear 12 is reduced to clamp the shaft center, and the outer edge 17 of the main gear 11 is expanded and the outer diameter is enlarged, and the main gear 11 and the sub-shaft The gears 12 are snapped together, and the inner diameter of the sub-gear 12 is engaged with the shaft center (not shown) of the reducer and engaged with each other. When the shaft rotates, the sub-gear 12 rotates together.
職是之故，如何解決必需分別在主齒輪及副齒輪上設置錐形斜面後再利用螺絲進行咬合之問題以及解決組裝費時費力的問題，經發明人致力於實驗、測試及研究後，終於獲得一種零間隙齒輪之傳動機構，除了有效地免除利用鎖緊螺絲以推動二個錐形斜面之外，亦能兼具避免副齒輪的內徑必需與減速機的軸心相咬合之功效。亦即本發明所欲解決的課題即為如何克服在主齒輪及副齒輪上需要分別設置錐形斜面再藉由螺絲鎖緊的問題，而使得副齒輪的作動得以更具有彈性，又如何克服副齒輪的內徑與減速機的軸心必需互相咬合的問題，以及如何克服必 需在複數個壓簧的二端分別施予壓力的問題等。 For the sake of the job, how to solve the problem that it is necessary to set the tapered bevel on the main gear and the sub-gear and then use the screw to engage and solve the problem of assembly and time-consuming and laborious. After the inventor devoted himself to experiment, test and research, he finally got The transmission mechanism of the zero-gap gear can effectively avoid the use of the locking screw to push the two tapered slopes, and can also avoid the effect that the inner diameter of the auxiliary gear must be engaged with the shaft center of the reducer. That is, the problem to be solved by the present invention is how to overcome the problem that the main gear and the sub-gear need to be respectively provided with tapered bevels and then locked by screws, so that the operation of the sub-gear can be more flexible, and how to overcome the vice The problem that the inner diameter of the gear and the shaft of the reducer must be engaged with each other, and how to overcome It is necessary to apply pressure to each of the two ends of the plurality of compression springs.
