Central distance invesely proportion to cos θ and cos the decreasing function so that.
Central distance in the gear having involute teeth is directly proportional to pressure angle.

Increases because the radius of the pitch circle increases as centre distance increases.
Cos (Pressure angle) = base circle radius/pitch circle radius.
Hence pressure Angle increases.
Cos (Pressure angle) = base circle radius/pitch circle radius.
Hence pressure Angle increases.

The Pressure angle remain constant.

Velocity ratio remain constant with change in Centre distance. For involute gears.
Pressure ratio remain unchanged from start to end of engagement. But if centre distance change it is changed.
