Description

The large dial index DTR series has the same internal components as the DT series but includes an innovative integrated reducer that allows the motor to be mounted on the right, left or with 2 motors (as shown). The internal reducer is a low backlash worm type compatible with high torque motors. Dual flange motors can mount directly to the index housing to increase the horsepower but still keep a small footprint. The input shaft is free to drive other peripheral equipment to stay synchronized with the indexing dial. The input can also drive our patented cam balancer (shown left) to offset the output load torque causing the motor torque requirement to be much less. Horsepower that was used to rotate the output load can be partially redirected to increasing the acceleration or decrease the deceleration. Fast index times can be achieved with small motor torque requirements. Large loads can be rotated with a less expensive smaller housing size to minimize the footprint. An inherent problem of rotating large indexing dials is waiting for the dial to settle or become motionless. The overall machine throughput will increase because the work done on the dial can be started sooner. Since the cam balancer torque compensation is adjusted with air pressure, fluctuating output loads can be accommodated with a turn of the air regulator. Air consumption is minimal, its equivalent of filling an air cylinder reservoir but not cycling it, its only uses air if the regulator is adjusted. Output backlash is minimized to reduce vibration which enhances the life and accuracy of the unit. Based on the advantages of the cam balancer, justifying this option is simple.
