The cam analysis apparatus tends to demonstrate the dynamic investigation of a cam mechanism at various speeds. The apparatus also allows the comparison among four typical cams with corresponding engaging members in terms of the motion behavior.

                                     
  • The apparatus allows the investigation of cam mechanisms.
  • By varying the spring stiffness, spring preload and oscillating mass, it is possible to study the dynamic limits of the respective cams.
  • The oscillating mass can be increased with 5 additional weights
  • The cam motions and valve raising can be clearly demonstrated using a stroboscope.
  • A recorder synchronized with the cam member records the actual elevation curve of the cam mechanism.
  • A speed-controlled drive motor with a large flywheel generates a speed as constant as possible.
  • The open design means that the motion is clearly visible in every detail.
  • A transparent protective cover ensures safe operation.
  • The apparatus includes various cam-shaped cam members: tangent cam, hollow cam, 2 circular arm cams with different head radius.
  • The unit also contains 2 different engaging members: flat receiver with plunger or rolling receiver with plunge & 3 interchangeable return springs and spring preload.
  • The unit is provided with an optical speed sensor.
