Busbar bolted joints
WebDec 1, 1997 · To keep bolted connections tight, we can choose from several methods. The most common is the insertion of a locking device between the rotating part (nut) and the parts being fastened (i.e., bus bars). That locking device often is a split-ring lockwasher. Such a device does not meet all locking device requirements, however. WebOct 1, 2010 · Okay I have sorted it I think, first calculate the clamping load of each bolt from the 15 ft-lbs using the equation:- F= T/ (0.2*d) where T= torque d = bolt dia 0.2 = friction factor F = 15*12/ (0.2*0.5) = 1000lbf now you have two bolts :- 2 * 1000lbf = 2000lbf joint pressure = 2000/ (2"*1") = 1000lbf/in^2 convert to N/mm^2 = 12.44 N/mm^2
