2D-Cam dialog: Roller Life tab


Before you can calculate the Roller Life, you must make sure you Configure the Power Source for the kinematic-chain with the Cam-Follower Part so that its power is from the 2D-Cam. See Configure Power Source


Catalogue names for Roller bearings include Track-Rollers, Track-Followers, and Cam-Followers.


To Calculate Roller Life, you must:


Parameters tab ( Parameters tab > Enable Lifetimes, Edit Safety-Factor  )

STEP 1:Enable Show Roller and Cam Life

STEP 2:Enter a Safety Factor (CAM)

Note: The Roller's Safety-Factor is equal to the Square of the Cam's Safety-Factor.

Top-Tip - Enter Safety-Factor = 1 to help you the basic Roller Life results, then enterparameters.

STEP 3:Select a Roller bearing manufacturer and Roller bearing

If you Enable ISO 281 Modification Factors:

STEP 4:Select or enter a Reliability Factor

STEP 5:Enter the Oil Operating Temperature, and Oil Viscosity at two other Temperatures (usually 40ºC and 100ºC)

STEP 6:Enter the Lubrication Type and select the Contamination Level.
