The diameter of the holes that are equally distributed around the bolt circle diameter Bolt circle diameter: the diameter of the circle on which the holes will be evenly distributed. Start angle: The 0° angle is to the right in the "X" axis and aligned with the center of the bolt circle in the "Y" axis.
Modeling bolts with shell elements In this type of modeling, beams are used to model the shank and shell elements are used to simulate the head and nut. For modeling bolts with shell elements, "Bolt with shell" option has to be chosen as shown in Figure 16. The user is prompted with a menu as shown in Figure 17 that accepts the required parameters.
May 31, 2006· Problem is the centering pin holes are so large that, when looking from the face of flange view, the remaining metal between a flange bolt hole and the centering pin hole is only 1.5mm (typical both sides of the centering pin hole).
weakening effect of the bolt holes. The justification for ignoring them, as most investigators of the flange problem do, is that stress redistribution can take place in the vicinity of the bolt holes to lessen the rise in stress, which the reduction in flange section at the holes might be expected to produce.
But I am still believe the overall cost of the plate + bolts and nuts still cheaper than ASME B16.5 flange for this case. Manway from plate only require 5/8 x 85 mm bolt while ASME flange will require 1 1/4" x 175 mm. Maybe not to much for 1 tank but we have 18 tanks.

Feb 08, 2007· I will let you know next week when the shell mill holder arrives but i am pretty sure the the bolt holes are covered by the 50 taper flange,if you look closly at the picture you can actually see the marks from the old holes at 45 degrees from the center line of the slot.
Enter values below to calculate the coordinates of the holes in a bolt circle.
Take a look at the flange hole relative to the fill hole on the trans. It's a bit lower than the fill hole. The typical rule of thumb when you're filling the trans is, on a level surface fill it up until it starts to dribble out the fill hole. So if the trans output flange hole is lower, some oil is going to come out when you pull the flange.

(b) If the mill has flanges along the shell, the peened liners may exert excessive force on flange bolts. This may not be a problem since the mill was designed for steel liners, but may, depending on the age of the mill and the maintenence philosophy for the mill flanges, need to be looked at. Mention has been made of appropiate tooling.
