3.1 Selection and use of the basic information(see attached 1)
3.2Selection and marking  
Need check the following items when selecting:
 The nominal torque of gear coupling
 The Permissible speed of gear coupling
 The maximum aperture of gear coupling
3.2.1 Standard selection method calculation of gear coupling
 The torque of coupling
formula  T<Tc≤Tn 
In the formula:T─Theory of torque,N·m;
      Tc─computed torque,N·m;
      Tn─Nominal torque,N·m;
 Theories torque calculation of gear coupling
Computational formula   T=9550Pw/n
In the formula:Pw─driving power,kW;
      n─working speed,r/min.
The torque calculation of gear coupling
 Computational formula  Tc=T·Kw·K·Kz
In the formula: Kw─Coefficient of engine (see table 1
             K─working condition coefficient (see table 1)
             Kz─Start coefficient (see table 1)  Selection and marking example
Known engine parameters: power Pw=30kw, rotate speed n=1500r/min, number of starts Z≤100times/h Coefficient of engine Kw=1.0;
Working machine parameters: application factor K=2.5; The driven end shaft extension of diameter d=35, Length L=43
Primary selection of gear coupling GBB2 type Tn=610N.m in GB series
The theory of torque T=9550Pw/n=191N.m
Computed torque Tc=191x1.0x2.5x1.0=477.5N.m
By the preceding formula knew that this gear coupling model can satisfy the torque requirements, and then inspect the rotate speed and bore diameter, to meet the structure and the requirement of parameter list. Therefore this coupling model specifications can be used.
Marked as: GBB2 coupling YA40x43/YA35x43(or GBB2 coupling 40x43/35x43)
3.2.2 When the presence of the following situation, it should be calculated and selection by the following method:
1  High peak loads
2 Brake (brake wheel or brake disc is part of the coupling)
3 High frequency axial channeling move load:
Use the following formula, when the motor torque is higher than general situation, Lacunar operation,possess impact load, start and brake moment of inertia or the system exists repetitive peak load. System peak load is the maximum load in the may exist in the system. Select coupling rated torque is equal to or greater than it according to the following formula to calculate the selection. No reverse peak load
selection torque(N·m)=system peak torque
or selection torque(N·m)=System peak power(Kw) ×9550/rotate speed(rpm) Have reverse peak load
  selection torque(N·m)=1.5×system peak torque
or selection torque(N·m)=1.5×system peak power(Kw) ×9550/rotate speed(rpm) Occasional peak load(no reverse)
During the coupling of the expectation life, if the system peak load appeared a number less than 1000 times, using the following formula:
selection torque(N·m)=0.5×system peak torque
or selection torque(N·m)=0.5×system peak power(Kw) ×9550/rotate speed(rpm)
For reverse situation, selects the step b. Selection and marking example(Have reverse peak load)
Choose a piece of gear coupling connecting with low speed shaft gear drive and reversing mill. Motor power is
37Kw, system peak torque is about 17000 n. m, coupling speed is 77 RPM, the drive shaft diameter is 120 mm,the key size is 32 x14, rolling mill shaft diameter is 135, the key size is 36x20, the max shaft end clearance is 14, both the motor shaft and the drive shaft extension is 135.
The minimum torque of selected coupling: Selection of torque=1.5x17000N.m=25500N.m=25.5KN.m
Primary selection of GBB11 from structure and parameter list, after verification, the nominal torque is 30.4 KN. M > selection torque 25.5 KN. M.bore diameter and rotate speed also meet the requirements, therefore available.
Marked as: GBB11 coupling YA120x135/YA135x135(or GBB11 coupling120x135/135x135) Brake
If the brake torque exceed the motor torque, calculate the selection torque according to the following formula:
      selection torque(N·m)= brake torque×application factor
Selection step is the same step with marking High frequency axial channeling shift
     If the axial channeling move exceed more than 5 times per hour, so the working condition coefficient should be increased by 0.25.
     Selection torque(N·m)=power(Kw) ×9550×(application factor+0.25) /rotate speed(rpm)
Selection step is the same step with marking
