2 GRID COUPLING

3 Selection Procedure GRID COUPLING Standard Selection Method The standard selection method can be used for most motor, turbine, or engine driven applications. The following information is required to select a flexible coupling: Horsepower or torque. Running rpm. Application or type of equipment to be connected (motor to pump, gear drive to conveyor, etc.). Shaft diameters Shaft gaps Physical space limitations. Special bore or finish information and type of fit. Standard Selection Example: Select a coupling to connect a 75 hp, 1750 rpm electric motor driving a lobe type blower. Motor shaft diameter is 2.375, blower shaft diameter is Shaft extensions are and Selection is replacing a gear type coupling with a.125 gap. 1. DETERMINE REQUIRED RATING: System Torque (lb - in) = 75 HP x 63, SERVICE FACTOR: From Table 4 for lobe type blower S.F. = 1.25 = RATING: Determine system torque. If torque is not given, calculate as shown below: HP x 63,000 System Torque (lb - in) = RPM Where horsepower is the actual or transmitted power required by the application (if unknown, use the motor or turbine nameplate rating) and rpm is the actual speed the coupling is rotating. Applications that require rapid changes in direction or torque reversals should be referred to Powerdrive Engineering. 2. SERVICE FACTOR: Determine appropriate service factor from Table 4, M Find Design Hp: Determine the Design Hp rating as shown below. Design Hp = S.F. xactual Hp 4. REQUIRED MINIMUM COUPLING RATING: Determine the required minimum coupling rating as shown below: Minimum Coupling Rating = S.F. x Torque (lb-in) 5. TYPE: select the coupling T-10 Or T-20 which is suitable for your application. 6. SIZE: Refer to Table 2 & 3 - trace horizontally form the required speed to a Hp value equal to or larger than determined in 3 step. Read the coupling size at a top of column. 7. CHECK: Check speed (rpm), bore, gap, dimensions and M-1 3. Find Design Hp: 1.25x75=93.75hp 4. REQUIRED MINIMUM COUPLING RATING: 1.25 X 2700 lb-in = 3375 lb-in 5. SIZE: From M- 2, A Size 1050T is the proper selection based on a hp rating of 107hp exceeding the required minimum coupling hp rating of 93.75hp. 6. CHECK: Allowable speed capacity of 4125rpm (T10) exceeds the required speed of 1750 rpm. Maximum bore capacity of that we can not find in size 1050T so we have to choose 1070T size. So selected size will be 1070T.

10 GEAR COUPLING

11 Selection Procedure GEAR COUPLING STANDARD SELECTION METHOD The standard selection method can be used for most motor, turbine, or engine driven applications. The following information is required to select a gear coupling. Horsepower or torque Running rpm. Application or type of equipment to be connected pump, drive to conveyor, etc.). Shaft diameters. Shaft gaps. Physical space limitations Special bore or finish information and type of fit 1. RATING: Determine system torque. If torque is not given, calculate as shown below. System Torque (lb - in) = HP x 63,000 RPM Where: HP (Horsepower) is the actual or transmitted power required by the application (if unknown, use the motor or turbine nameplate rating) and RPM is the actual speed the coupling is rotating. 2. SERVICE FACTOR: Determine the appropriate service factor from Tables 3 on N-3 3. REQUIRED MINIMUM COUPLING RATING: Determine the required minimum coupling rating as shown below: Minimum Coupling Rating = S.F. x Torque(lb-in) 4. Find Design Hp: Determine the Design Hp rating as shown below. Design Hp = S.F. xactual Hp 5. TYPE: Refer to N-4 To N-7 and select the appropriate coupling type. 6. SIZE: Refer to Table 2 - trace horizontally form the required speed to a Hp value equal to or larger than determined in 4 step. Read the coupling size at a top of column. 7. Check: Check bore, speed, Dimensions and Torque rating of coupling. Bores Check shaft diameters against coupling maximum bore. If bore is inadequate, consider the use of a reduced key from engineering tables, or select a larger size coupling. Speeds (rpm) Check the operating rpm against the coupling allowable speed. If catalogued values are inadequate, consider balancing. Balancing may allow up to 50% increase in speeds shown. STANDARD SELECTION EXAMPLE: Select a gear coupling to connect a 500 HP, 1170 RPM electric motor to a drive high speed shaft of a maneuvering winch. Maximum shaft separation is.250". Motor shaft diameter is 3.375" and keyway is.875" x.438". Winch shaft diameter is 3.000" and keyway is 50" x.375". Motor and winch extensions are both 6.000" long. 1. DETERMINE REQUIRED RATING: System Torque (lb in)) = 500HP x = 26, rpm 2. SERVICE FACTOR: From Table-3, N-3 for maneuvering winch S.F.= REQUIRED MINIMUM COUPLING RATING: 1.5 x 26,923 lb-in = 40,385 lb-in 4. Find Design Hp: 1.5 x 500hp=750hp 5. TYPE: From N-4 & N-5 to connect close coupled shafts (.250" gap) the double engagement Type 1025GC02 or Type 1025G20 coupling is the selection. 6. SIZE: From N- 2, A Size 1025G is the proper selection based on a hp rating of 750hp exceeding the required minimum coupling hp rating of 1230hp. CHECK: Maximum speed capacity of 3,330 (1025GC02) and 5000 (1025G20) rpm exceeds required speed of 1170 rpm. Maximum bore capacity of 3.625" exceeds the actual shaft diameters and torque rating of 66, 150 lb-in exceeding the required minimum coupling rating of 40,385. So selected coupling will be 1025GC02 or 1025G20 TABLE 1 Torque and Horsepower Ratings Coupling Size Torque Rating (lb-in) HP per 100 RPM 1010G/GC 10, G/GC 20, G/GC 37, G/GC 66, G/GC 107, G/GC 163, G 270, G 371, G 500, G 655,200 1, G 800,100 1, G 1,197,000 1,900 Dimensions Checks are: length of hubs and alignment clearances against shaft lengths, outside diameter of coupling against radial clearances N-1
