Controlling motion through engineered solutions. The Hilliard Corporation offers a broad line of industrial clutches—designed, manufactured and sold according to our customer’s specifications. Hilliard’s line of industrial clutches provide dependable solutions to problems of torque control, overload protection, positive engagement and high torque on demand.
Hilliard Overrunning clutches are used to transmit power between a shaft and a gear, sprocket, sheave, or pulley mounted on the clutch or to directly connect two shaft ends. The roller type clutch construction is one of the oldest over-running or free wheeling designs.
INTERMITTENT MOTION CLUTCHES
The Hilliard Corporation’s Intermittent Drive Units (IDU) are packaged mechanical assemblies that produce precise intermittent motion-on-demand from a constantly rotating input. Intermittent Drive Units feature a self-contained lubrication system, making them ideal for dusty, dirty, steamed or washed-down applications. Foot-mounted housings with input and output shafts simplify installation.
TORQUE LIMITING CLUTCHES
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.
The Hilliard centrifugal clutch provides automatic, gradual, cushioned engagement over a speed range on high-inertia loads. It smooths out and reduces starting current surge. Centrifugal clutches are slip-free at rated load and speed. They protect against overload by limiting torque, absorbing shock and eliminating torsional resonance. Hilliard centrifugal clutches have soft transmission of power and load free starting. Hilliard’s linkless centrifugal clutches combine a dowel pin, vibration dampening bushing and a symmetrical spring design. The results are a long service life at an economical price. Other benefits include soft starts, load-free starting and overload protection. Hilliard’s centrifugal clutches are ideal for applications such as fans, blowers, conveyor drives and mills. Our engineering and manufacturing capabilities offer a wide range of choices, from common mounts to custom designs.
EXTREME DUTY SPROCKET CLUTCH
The Extreme Duty Sprocket Clutch is ideal for everyday demands of go-karts and youth-model snowmobiles. A thermo-dynamically designed clutch shoe increases the clutch’s capacity to absorb heat without damaging the clutch springs, resulting in longer life and better reliability.
EXTREME DUTY PULLEY CLUTCH
The Extreme Duty Pulley Centrifugal Clutch is ideal for retrofit or new equipment application. The clutch was designed to be a low-cost upgrade to the current low- priced centrifugal market and is ideal for the everyday demands of chipper, shredders, power trowels, concrete mixers, power screeds, air compressors, lawn and garden equipment and more.
