Speed ratio | For Reduction Ratio Selection, use this formula: Reduction Ratio = Required Output RPM / Input RPM of CORONET REDUCER * See“REDUCTION RATIO, INPUT POWER, & FRAME SIZE SELECTION CHART”. | Reduction
ratio,input power & frame size 작업표 |

Required torque | Determine model and frame size by multiplying service factors by required torque according to the required torque listed. * See“LOAD CLASSIFICATION TABLE ”. | Coronet reducer service factors 작업표 |

Starting/peak torque | Select model, the allowable torque of which does not exceed 250% of the rated torque. For frequent starting conditions, select model in consideration of this formula: Load GD2 < Motor GD2 × Reduction Ratio2 * See“SELECTION TABLE”. | 작업표 |

Load conditions | Load conditions Select model, allowable overhung and thrust load of which does not exceed the allowable load listed. Method of coupling devices and the load, ・Coupling ･･･No load other than rotating force . ・Pulley, Chain, & Spur gear･･･Overhung load. ・Helical gear, & Bevel gear･･･Overhung load + Thrust load. * When using chain gear, its P.C.D. must be 3 times larger than the dia. of the shaft. When using chain gear, its P.C.D. must be 3 times larger than the dia. of the shaft. |
