Automobile Designer Interview Question:

Please explain the advantages of Cycloidal and Involute gears?

Submitted by: Administrator

The advantages of the Cycloidal gears are as follows:
☛ > Having a wider flank as compared to Involute gears they are considered to have more strength and hence can withstand further load and stress.
☛ > The contact in case of cycloidal gears is between the concave surface and the convex flank. This results in less wear and tear.
☛ > No interference occurs in these types of gears.
☛ The advantages of Involute gears are as follows:
☛ > The primary advantage of involute gears is that it allows the changing of the centre distance of a pair without changing the velocity ratio.
☛ > The pressure angle remains constant from start to end teeth, this results in less wear and smooth running of the gears.
☛ > The involute gears are easier to manufacture as they can be generated in a single curve ( the face and flank ).
