It can be determined by measuring the distance between any corresponding points of adjacent threads parallel to the axis. It is note that the axial pitch of a worm is equal to Circular Pitch (Pc) of the mating worm gear.

  1. Selection of the material:
  2. Calculation of teeth:
  3. Calculation of diameter factor and lead angle.
  4. Calculation of Tangential load:
  5. Calculate b, d2, v.
  6. Recalculation of beam strength.

  8. Calculate basic dimensions.

Which material is best for worm gear?

Typically, for worm gears, we recommend tin bronze (C91700) and aluminum bronze (C95400 and C95500) due to their relatively high strength, and superior fatigue, friction, and wear resistance. The process of making bronze involves first heating the copper element to a specified temperature.

How do you find the lead angle of a worm gear?

The worm lead angle and the worm helix angle, ψW, are related by λ = 90 degree − ψW. The lead angle will vary from the root to the outside diameter of the worm as indicated in Fig. 11.8. Generally self-locking occurs for lead angles below 6 degree.

How do you find the helix angle of the worm gear?

The formula Helix angle = Atan (Lead of Screw/Circumference of Screw) or α= atan(L/C) is used to calculate the Helix Angle, which is represented by α symbol.

Why Mona Lisa has no eyebrows?

Using the 240-megapixel scans, Mr Cotte, 49, says he can see traces of a left eyebrow long obscured from the naked eye by the efforts of the restorers.
