VTMF Servo Trunnions
The VTMF Series Rotary Index Table Servo Trunnion was designed to be a completely programmable solution. This allows for a minimum of 4 oversized cam followers to be engaged with the barrel cam at all times. This programmable rotary indexing trunnion is driven directly by a gear reducer coupled to either an AC motor with encoder or servo motor. Both options provide very high accuracy (less than 10 arc seconds) and allow for the indexer to be driven by a dedicated amplifier or as an auxiliary axis to a robot drive. Loading capabilities are multiplied significantly in this line of indexers through the design of the barrel cam and cam followers. This unique design allows for unprecedented inertial load as a function of index time capacity.
Advantages for design engineers and special machine builders
- Large center thru-hole
- Dowel holes in housing and in output flange
- Recessed center column – No obstruction
- Simultaneously rotating input shaft extension – Optional on opposing side of gear reducer
- Optional synchronization of other devices either electronicalyl or mechanically
Technical benefits for users
- Extremely reliable with long service lives
- High efficiency (>90%) mechanical components require less input power
- Flame hardened cams and cam followers
- Internal components immersed in oil bath
