Theory of Machine The velocity of sliding of meshing gear teeth is(Where ω₁ and ω₂ are angular velocities of meshing gears and ‘y’ is distance between point of contact and the pitch point) (ω₁ + ω₂) y (ω₁ + ω₂)/y (ω₁/ω₂) y (ω₁ × ω₂) y (ω₁ + ω₂) y (ω₁ + ω₂)/y (ω₁/ω₂) y (ω₁ × ω₂) y ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile ANSWER DOWNLOAD EXAMIANS APP
