Factors Affecting Selection
The following is really a record from the facts needed to assist in producing a coupling variety. Not all of these things will come into play in all variety processes. These goods contain, but are not limited to:
Application related:
Application specifics
Type of motor and driven tools
Motor horsepower or KW
Operating/coupling speed
Shaft sizes and separation
Area and dimension constraints
Surroundings (temperature, chemical compounds, etc)
Balance needs
Specific modifications
Techniques In Selecting A Gear Coupling
Refer to the gear coupling specs charts displayed with every single kind of coupling throughout the Gear Coupling Merchandise part of this catalog. The photographs and charts offer visualization, specifications, and dimensional data for its wide selection of gear coupling products. Typically start with an F Variety flanged gear coupling or a C Type steady sleeve gear coupling (page G-16) and proceed from there.
Step 1: Overview the gear coupling series and type as picked to be sure the choice
meets application requirements.
Stage 2: Figure out the nominal application torque in in-lbs by utilizing the next formula:
Application Torque ( in-lb ) = (HP x 63025)/RPM
Or Nm = (KW x 9550)/RPM
Step 3: Review the Application Service Element chart to the support element variety connected together with the application exactly where this coupling is going to be utilized. Multiply the application torque by the application service element to determine the complete torque essential for that coupling 
assortment.
Phase 4: Evaluate the necessary complete torque worth with the nominal torque capacity
listed in the Gear Coupling Variety chart for that wanted coupling form.
Step 5: Check the highest bore dimension along with the highest RPM in the coupling
kind chosen to guarantee the coupling will meet these application needs.
Step 6: Note any specific demands which includes the BSE dimension for floating shaft and spacer styles, shear pin torque, slide coupling specifics, mill motor tapered shaft data, and every other pertinent facts.
