DRIVE COUPLINGS

Torq-Tenders positive-drive couplings provide accurate overload protection in virtually any mechanical power transmission system, and are available in custom models and sizes. These are mechanical torque-limiter couplings that disengage motor drives when torque is exceeded to protect the entire system. When load exceeds the Torq-Tender rating determined by precision-tempered torque springs, the units' drive key pivots out of a slot to disengage the Torq-Tender coupling. Once the overload is removed and the speed reduced, the units automatically resets themselves.

Among the designs available is a through-shaft, bushed model where applications require a drive shaft extended through the complete Torq-Tender unit. There are designs that include face-mount, end-of-shaft models, end-of-shaft self-supporting models, and variations within each model to accommodate special input bores, splines, housings, and non-standard mountings. The smallest standard Torq-Tender is the TT1X with a 2 to 60 in.-lbs, torque rating. The largest is the TT4X with a 750 to 3,000 in.-lbs, torque rating. Zero-Max, 13200 6th Ave. N.,

CONVERSION MODULE

This new conversion module converts servo motor control signals to stepper motor control signals. It can control four independent stepper motors. The Servo-to-Step is an active termination panel that converts a [+ or -] 10 V signal to the stepper CW/CCW (direction) and STEP (clock) signals. If the stepper motor doesn't have an encoder for position feedback, the board can be configured to synthesize quadrature signals. The maximum stepping rate is user-selectable via a DIP switch from 7.6 Hz to 31.25 kHz. Motor direction and enable are also configurable.

The unit will work with any servo motor control software that uses analog voltage for velocity and incremental encoder pulses for position feedback.
