Theory of Machine In a circular arc cam with roller follower, the acceleration in any position of the lift will depend only upon Total lift, centre of gravity of the cam and cam speed Radius of circular arc, cam speed, location of centre of circular arc and roller diameter Mass of cam follower linkage, spring stiffness and cam speed Total lift, total angle of lift, minimum radius of cam and cam speed Total lift, centre of gravity of the cam and cam speed Radius of circular arc, cam speed, location of centre of circular arc and roller diameter Mass of cam follower linkage, spring stiffness and cam speed Total lift, total angle of lift, minimum radius of cam and cam speed 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 Because of difficulty in manufacturing cam profile Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits ANSWER DOWNLOAD EXAMIANS APP
