Selection Procedure
Select an appropriate SERVICE FACTOR from table given below.
Multiply tyre rated running power by the service factor This gives DESIGN POWER at rated speed (rpm) Convert this to design power at 100 rpm. This is used as a basis for coupling selection.
Refer to the rating column and read until the power greater than or equal to the design power al 100 rpm is found. The size of the gear coupling Is given angle corresponding first column. Check the max bore capacities. If required bore size is given in the corresponding first column. Check the max. bore capacities. If required bore size is greater than the max. bore of selected coupling size, the go for higher size meet the required bore.
