Question

Suppose you have an input gear that always turns clockwise. Suppose you have an output gear that does not engage the input gear directly. Show, using diagrams, how you can design a gears train to generate:
a. A "Forward movement at the output.
b. A "Reverse" movement at the output.

Answer 1

Answer:

Please find attached the required diagrams for;

a. A "Forward" movement at the output

b. A "Reverse" movement at the output

Explanation:

The direction of turning of the input gear = Clockwise

The engagement between the input and the output gear = Indirect engagement

a. For a "Forward" movement at the output, we have;

The number of idler gears between the input and output gear = 1

The direction of turning of the input gear = The direction the output gear turns

b. A "Reverse" movement at the output

For a "Reverse movement at the output, where the input and output gears do not directly engage. the number idler is increased is increased

∴ The number of idler between the input and output gears = 2

The direction of turning of the input gear = Opposite the direction the output gear turns
