selection guidelines required information 1 number of hours of daily operation 2 classification of load and prime mover 3 horsepower or required torque to be transmitted and shaft speed in revolutions/minute 4 diameter of both shafts method for selection 1 based on the operating conditions determine the service factor using table 1 2 obtain the design horsepower by multiplying the horsepower to be transmitted by the service factor 3 with the required rpm choose the coupling that satisfies the horsepower from the horsepower rating shown in table 2 4 when the required shaft diameter exceeds the maximum bore diameter of the coupling you have chosen use a coupling that is one size larger 5 in the low-speed range the shearing pressure might be too great when using a standard key in this case calculate the key shearing pressure to determine if it is necessary to use a special key or spline bore 6 note the lubrication system required and select the coupling cover as necessary in all applicati

installation 1 place the oil seals for the cover on the sprocket halves 3 measure the distance c between the sprocket faces and firmly fasten the set bolt refer to specifications table pg.4 4 lubricate the chain with grease then wrap the chain around both sprockets and fix with the connecting pin 5 fill the required quantity of grease into both sides of case and fasten them firmly do not forget to use gaskets notes 1 during high-speed operations or conditions of large vibration please use locking cement when fastening the bolts 2 install a cover when there is a risk of chain breakage 3 ambient temperature range is 14° to 140°f if you will use the coupling outside this temperature range please consult with u.s tsubaki 2 bring the sprocket faces close together and correct the angular and offset misalignment adjust the angular misalignment alpha symbol so that the width of the tooth surface t is the same around the circumference of the sprockets the allowable angular misalignment is 1°
