Is there an increase in input torque required with our cam follower design or is there any other outward effect of that design vs. the needle bearing?
When a rotary table is sized for an application, the indexer, gear reducer and motor of the transmission are sized to handle the entire weight and load of the project. When an indexer is in dwell, and the motor starts to turn the input shaft of the indexer there is no load to move other than the cam-shaft mass itself. The motor needs only to turn the input shaft as it proceeds through the dwell portion of the cam. So even though the starting breakaway torque of a solid journal type cam follower is a little higher than a needle bearing type, it has absolutely no influence as it is minor of the comprehensive sized capacity for the entire transmission, once the motor starts, there is no difference for the application. Of course the indexers cannot be operated simply by turning the input shaft by hand, especially as the model size increases, but it can be done easily by means of a tool with a short lever arm. People are typically not aware of the positive influence that this technology bri
