Motorized Cam Indexer

Motorized Cam Indexer is an integrated precision transmission device that combines a "drive motor" and a "cam indexing mechanism". The core function is to provide power through a built-in motor, which converts continuous rotation into fixed angle intermittent motion at the output end through the cam mechanism. It combines the power output of the motor with the precise positioning characteristics of the cam indexing, and can directly achieve the complete transmission process of "power input intermittent indexing stable stop" without the need for additional external motors, reducers, and other components.

Motorized Cam Indexer focuses on "motor-driven+cam controlled indexing":

the equipment contains customized driving motors (stepper motors or servo motors), cam components, follower units, and output systems - the motor starts after receiving control signals and drives the cam to rotate continuously through couplings (or direct connections); The cam profile is designed according to the "smooth intermittent motion law".

When the cam rotates to the "indexing section", it pushes the driven part to drive the output shaft to complete the preset angle rotation; When the cam enters the "stop section", the driven part closely adheres to the cam profile, and the output shaft stably stops until the motor drives the cam to enter the next cycle.

FAQ:

1. What speed ratio is suitable for selecting a cam indexer for multi station equipment (such as 16 stations)?
    Choose a 16-stop indexer with a 16:1 speed ratio (16 input turns per output turn). This ratio gives one index per input revolution. It matches the station count and provides enough dwell time for multi-station equipment.

2. What is the difference in speed ratio selection logic between light load high-speed equipment and heavy load low-speed equipment?
   Light load high-speed equipment uses a smaller speed ratio. This reduces inertia and allows faster input rotation. Heavy load low-speed equipment uses a larger speed ratio. This increases output torque and lowers impact forces.

3. How long is the customization cycle for non-standard speed ratios? Will the cost increase significantly?
     Customization takes 6 to 12 weeks. Manufacturers need to redesign and grind the cam curve. Costs increase significantly, typically 30–50% higher than standard ratios.

4. What is the allowable deviation range between the actual operating speed ratio and the theoretical speed ratio of the cam indexer?
Allowable deviation stays within ±0.5% of the input angle. This limits output position error to ±0.01°–±0.02°. Larger deviation will harm positioning accuracy.
