Magna Torque (MT)


Hilliard’s line of overrunning clutches is economically priced and ideally suited for backstopping and gearbox applications. Custom designs and rapid prototyping are available. The overrunning clutch can be used for ratchet-type indexing operations such as packaging equipment and printing presses. When used in conjunction with a torque arm to hold the output shaft, Hilliard overrunning clutches provide instant backstopping protection with zero backlash from reversed rotation whenever power to the conveyor’s drive unit is interrupted.

Applications

Industrial Fans - Material Handling - Packaging/Printing - Steel Industry

Type: Backstopping & Indexing

Sprag Clutches


Hilliard Sprag Clutches are designed for overrunning, backstopping and indexing applications. This clutch is a freewheeling device with an inner race and an outer race, either of which can be the input or output member. The input can drive the output in a chosen direction and permit the output to overrun in the same direction. The clutch consists of a cage full of steel sprags or wedges, located in the space between concentric inner and outer races. Power is transmitted from one race to the other by the wedging action of the sprags between them. Rotation in one direction causes the sprags to tilt and wedge, preventing rotation. This allows free rotation in the opposite direction.

Applications

Industrial Fans - Material Handling - Mining - Packaging/Printing - Printing Press

Type: Backstopping & Indexing

Single Revolution


Hilliard single revolution clutches provide output cycles, on demand, from a continuously running input. The output cycles can be a fraction of a revolution, one revolution or multiple revolutions. This clutch typically provides five times the duty life of wrap spring clutches for indexing, shearing, bending, fastening, loading or similar applications. Each clutch is designed for a service life of up to 40 million cycles.

Other features include; positive engagement at any point of revolution without slip, lag or cumulative error, automatic disengagement at the same point of each operating cycle, no deterioration in performance throughout service life, ruggedly built and field proven, and controlled by a single trip lever which may be activated by a solenoid, an air cylinder or other mechanical devices.

Applications

Packaging/Printing

Type: Cyclical on demand motion when triggered

Intermittent Drive Assembly (IDA)


IDA’s are easy-to-install, self-contained packages that include a solenoid-operated, single revolution clutch with available anti-rollback and anti-overrun features. Other features include: rugged roller-ramp clutch design, dimensionally interchangeable with wrap-spring units, heavy-duty rotary solenoids operate on 115 VAC or 12, 24, or 90 VDC, pneumatic operation available. These units are available in clockwise or counterclockwise rotation with a convenient four-bolt mounting flange. Other options include rubber shock mounts, non-standard key location and multiple stops.

Intermittent Drive Packages (IDU, & IDU/ADU)


The IDU consists of a single revolution clutch and all necessary controls engineered into a compact, totally enclosed, foot mounted housing. This unit is also available with a unique acceleration-deceleration unit (IDU/ADU) which provides smooth acceleration and deceleration of the output shaft.

Applications

Packaging/Printing

Type: Cyclical on demand motion w/Gearbox

Friction Torque Limiter


Torque limiters and couplings are designed to slip during a torque overload, while still transmitting the adjusted torque. They provide dependable solutions to the problems of torque control and overload protection in power transmission equipment. These clutches include one or more friction discs mounted on an inner hub, a single nut adjustment to easily pre-sets the torque. Similar static and dynamic coefficients of friction provide for extremely smooth torque control.

Applications

Outdoor Power Equipment - Packaging/Printing - Steel Industry

Type: Overload Protection
