6 A TAPER GRID COUPLING A > TAPER GRID COUPLING 1 특징및장점 (Characteristic & Merit) WCC Taper Grid Steel Flexible Coupling 은아래의특성및장점으로인하여사용상편리함은물론원가절감의효과가탁월하다. We can get more favorable convinience and cost down by using the WCC Taper Grid Steel Flexble Coupling. 1) 평행오차축이편심상태일때 Grid 가 Grease 를칠한홈안에서작동함으로써진동이나충격을완화시켜무리함이없는동력전달을한다. ( 허용오차 2 mm ~3 mm ) 1) PARALLEL The movement of the grid in the lubricated grooves accommodates parallel missalignment and steel permits full functioning of the grid-groove action in damping out shock and vibration. 2) 각도오차축이편각 (2 ~3 ) 상태에서도곡면으로파여진 Hub 의홈 (Groove) 안에서, Grid 가미끄러지는윤활작용과탄력으로동력이손실없이전달, 작동된다. 2) ANGULAR Under angular misalignment, the grid-groove design permits a rocking and sliding action of the lubricated grid and hubs without any loss of power through the resilient grid. 3) 축유동오차구동측과피동축이상하진동과좌우유동되더라도 Grease 를칠한 Hub 의홈안에서 Grid 가구부러진안쪽까지자유로이작동함으로진동의전달을방지하고동력을전달한다. 3) AXIAL End Float for both driving and driven members is permitted because the grid slides freely in the lubricated grooves. 4) 비틀림에대한유연성기계가시동시발생하는충격 진동 과부하등이 Grid 에작용하게되면 Grid 의유연성으로인해힘의작용점이 Tooth 의곡면안에서이동되므로진동과충격부하를감소시켜준다. 이것은 WCC Taper Grid Coupling 이갖는뛰어난장점이다. 4) TORSIONAL FLEXIBILITY Torsional flexibility is the advantage of WCC Taper Grid Couplings, Providing flexible accommodation to changing load conditions. 6 woo chang coupling

7 TAPER GRID COUPLING A 1 경하중작용시 Grid 상태 Grid 가 Hub 의 Tooth 외각에서힘을받아직선인상태로작동됨으로부하 (Load) 가발생하면 Tooth 의곡면과 Grid 의탄력작용으로 Vibration 과 Shocking 을없애준다. Light Load The grid bears near the outer edges of the hub teeth. The long span between the points of contact remains free to flex under load. 2 정상부하에서의 Grid 상태부하가발생하면힘의걸림점이 Hub 의 Tooth 중간으로이동되어 Grid 가휘어지는 (Bending) 탄력으로충격하중을완화시켜전동한다. Normal Load As the load increases, the distance between the contact points on the hub teeth is shortened, but a free span still remains to cushion shock loads. 3 시동시충격부하에서의 Grid 상태순간적인과부하로힘의걸림점이 Hub 의 Tooth 제일안쪽으로이동되어 Grid 가비틀리는 (Torsion) 탄력의범위내에서극도의충격 (Shocking) 을유연하게완화시켜 Starting 된다. Shock Load The coupling is flexible within its rated power capactity. Under extreme overloads, the grid bears fully on the hub teeth and transmits full load directly. 아래그림은상기와같은우수한특성들을증명해주고있다.

67 UNIVERSAL JOINTS H 선정기준각도 10 의경우최대허용 TORQUE가표시되어있으나 10 를초과할경우아래의보정계수값 (F) 을보정해야합니다. CRITERIA FOR SELECTION OF JOINTS The tables give the maximum allowable torque (expressed in Kgm.)caculated on the basis with an angle of inclination of 10 and continuous use. If the inclination angle is over 10 the values shown will be reduced in accordance with the torque factors shown below. 각도별 보정계수 ANGLE UP TO FACTOR F [ 예 ] 아래조건의경우 JOINT의선정은? power(n) : 3HP speed(n) : 2,000rpm 각도 (α) : 20 Example Example : criteria for selection of joint after taking into account the power to be transmitted. the speed and the angle of inclination. : power N 3HP speed n 2,000 rpm angle α x N x 3 TORQUE MOMENT(Mt)= = = 1,074Kgm. n 2,000 각도 (α) : 20 이므로적용되는보정계수 F=0.75 이므로선정할 JOINT의 TORQUE MONENT(Mt) 는아래와같이적용되어 1,432Kgm 입니다. The torque to be transmitted is 1074Kgm. but since the joint angle is 20 one must select a joint of larger dimensions and torque carrying capacity to compensate. Since the torque factor for 20 is 0.75(as indicated on the table) one divides the Mt by F. MT = MT 1,432Kgm. F 0.75 Mt가 1,432Kgm 이거나조금큰 size를선정합니다. The appropriate joint should have a torque capability of 1,432Kgm. or greater whech is selected from the table of joints. Pay attention that 1 Kgm. = Nm. woo chang coupling 67

69 주의사항 UNIVERSAL JOINTS H 샤프트와유니버샬 JOINT 와완전한동력전달을하기위하여아래의주의사항을지켜주십시요. The permise for perfect working of shafts with universal joints is the scrupulous observation of the following installation conditions : 일정한운동을위하여양샤프트의각도를같도록해야하며같은수평면에놓여야합니다. To obtain uniformity of movement it is essential that the angles of the two shafts should be equal and lie in the same plane. 각도에따른속도변동을방지하려면구동축과피구동축샤프트는평행하게배치되어야합니다. The input shaft and the driven shaft can only be disposed parallel to each other in order not to produce resulting angular velocity variations which have not been compensated. 샤프트지지베어링은가능한 joint 에근접한부위에설치한다. The shaft support bearings should situated as close as possible to the joints to reduce radial loads. woo chang coupling 69
