Rotary Index Tables By Motion Index Drives

Motion Index Drives has developed the new standard for fixed or flexible Indexing Rotary Table. The TMF series of servo driven programmable rotary tables was engineered to meet our customer’s vision of the ideal programmable rotary table and to exceed expectations.

The TMF Series is an innovative line of programmable rotary index tables with zero backlash operation. These rotary indexing tables are built to maximize the potential of Motion’s flex technology with streamlined housing and dial plate to match. The power to rotate the index drive is provided either by means of servo motor coupled to a gear reducer or AC motor with encoder, coupled to a gear reducer. Our servo programmable rotary tables are manufactured to be identifiable by all robot brands and controls. The index drive is completely sealed to eliminate intrusion from foreign particulate matter and fluids.

The rotary index table transforms a constant input drive motion into an intermittent output drive motion. The intermittent drive motion occurs by means of a flame or inductively hardened and high accuracy-milled barrel cam. The use of mathematical laws of motion guarantees a soft, shock-proof and jerk free movement that has been optimally designed for its intended purpose. The designed assembly allows for accurate and secure mounting to the output dial which is also backlash free.

The power is provided either by means of a three-phase brake motor via a gear reducer or by means of a chain-wheel or belt-wheel on the drive shaft of the rotary index table. This is firmly connected to the barrel cam, without any further internal gear sets, and it turns the cam followers and subsequently the output flange. The output flange is mounted within a wire bearing assembly, backlash free of play (within steel ring – not in casting). The index drive is completely sealed to eliminate intrusion from foreign particulate matter and fluids.
