The pulley diameter is mainly determined by the conveyor belt class, but the required shaft diameter also influences the diameter. A golden rule for the pulleys diameter is that it should be at least three times the diameter of the shaft. Pulley Types. There are two main types of pulleys the Turbine pulley and the TBottom Pulley.
Bending is a procedure for forming a flat, sheet metal workpiece. It immediately follows cutting in the processing chain. The workpiece lies on a bottom tool with a vshaped opening. A wedgeshaped tool (punch) presses the workpiece into the vopening and thus bends it to the desired angle.

If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value. For example, if your small pulley is 80mm diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 400 RPM, Enter Pulley1 80, Pulley 1 RPM 1000, Pulley 2 RPM 400 ...
Shear and Bending Moment in Beams Consider the Beam shown carrying some loads. We can find out the reactions R Aand R Bfor external equilibrium. To find the internal forces, consider the cut shown. The following convention is adopted for the positive shear and bending moments in beams. Tuesday, November 17, 2009 11:01 PM CE297 FA09 Ch7 Page 3

A simple pulley system, which is more compact than shown in the picture above and in which the end of the line is attached to the anchor. Here F А is the anchor load, F E is the effort force and F L is the load. The mechanical advantage is defined as in the picture above, that is MA = 2n where n is the number of moving pulleys. For example, if there are two movable pulleys, the MA = 4
· Way back when I was 15, I made a degree wheel from cardboard and marked my old 40hp pulley using this method since I had no idea how to remove my stock pulley with the engine in the car. You only need to put a couple of marks on the pulley, obviously one to give yourself an idea of where 30 degrees is for setting total advance, and another one at 180 for setting the #2 and #4 valves quick and ...
