Size 5107 Screw Conveyor 100 overload, or 200 of nominal motor rating . Class II Selections 180 overload, or 280 of nominal motor rating . Class lIl Selections 300 overload, or 400 of nominal motor rating . If the maximum starting or momentary load exceeds the above conditions, refer to.

Sheave Ratio Calculation

For example, if the motor speed is 1750 rpm and the gear drive output speed is 35 rpm, the total ratio required is 50. The nominal gear drive ratio closest to the total ratio required is 40. For a 207TR, the actual ratio is 39.124. Therefore, the sheave ratio required in this case is 1.278.

Difference Between Nominal And Major Diameter In Threads

Feb 28, 2013 Nominal diameter is the diameter from crest to crest that the fastener is listed as. i.e. a 18 bolt has a nominal diameter of .125 inches. However, if you measured the outside diameter of the fastener from crest to crest you would find it slighly different positive or negative depending on the material, grade, purpose, etc. depending on the manufactured tolerances.

The maximum diameter within tolerance at the crest of the screw threads, called the max major diameter of external thread, is that of the basic thread form and equals the nominal diameter, D, stated in the screws designation the minimum diameter within tolerance at the crest of the nut thread, called the min minor diameter of internal.
