Characteristics
The rotary tables are mechanical units with orthogonal axes, where the continuous rotation of the input shaft results in the conversion into an intermittent rotation of the output disc. This is accomplished by mounting the cam to the input shaft and then an indexing disc holding the cam follower integrated with the output disc. The profile of the cam and number of cam follower bearings applied determine the type of index movement that occurs. The number of stations (2 to 32 with the possibility to have up to 540 stations) will be determined by the mechanism according to the customer’s requirements. The index time from station to station is directly proportional to the cam angle and the input RPM. The compact and robust structure of the Autorotor index tables, along with the tailoring of requirements with all the highest standards of performance, high axial as well as the radial load capacities is a standard for Autorotor.
The Autorotor index table is maintenance free and over the time the highest levels of accuracy occur due to the acceleration and deceleration of the indexing disc through the displacement generated by the cam and by the absence of backlash.
Application
Indexing tables are generally mounted on:
- Assembling machines
- Packing equipment
- Manufacturing equipment
- Automated welding machines
- Movement devices
- Machining isles
- Filling machines
- Printing machines
Advantages
The main pros are:
- High speed continuous and totally controlled displacement
- Smooth running also at high frequence
- Self-Iocking in dwell position
- High repeatability
- Low maintenance
- Low installed power
- Possibility of using continuously moving cams, driven by servomotors
