SEPAC announces line of thrust reverser brakes for aviation use
SEPAC Inc. has announced a line of high-performance thrust reverser brakes, which are used to prevent the thrust reversers on an airplane from being engaged in flight. SEPAC’s thrust reverser brakes are suitable for any aerospace application, and are currently used on platforms such as the Airbus A380 wide-body jet and the Irkut MC-21 Russian airliner. […]
Expanded size selection for BX Series brakes from Miki Pulley
Electromagnetic BX series brakes from Miki Pulley are a power-off, engaged type brake. Of the BX series, the BXR-LE has expanded to three additional sizes, with six total size configurations to choose from. These brakes boast advantages including a slim design and high holding torque in a compact package. They provide quiet operation with long […]
Compact CYT Micro Clutches from Miki Pulley
Miki Pulley offers its CYT Micro Clutches for direct sale to OEM’s in North America. These CYT Clutches are designed for compact precision applications and may be easily mounted to a driven shaft. Further custom variants can be realized by pairing a sprocket, timing pulley, V-belt pulley or shaft to the armature. The clutches accurately […]
Nexen introduces ring drive with built-in brake, zero backlash
Nexen Group Inc. has introduced the patent pending CRD 250B, an expansion of the company’s innovative Compact Ring Drive (CRD) system. The 250B includes a built-in zero backlash locking/brake design that delivers twice the nominal torque without increasing the CRD footprint. It is extraordinarily durable, with a brake life of 1 million cycles, and requires […]
Example of tight torque-limiter integration for overload protection
Ideally engineers would anticipate the need for overload protection in a drivetrain and include it in the original design. But overload problems often only appear after equipment is in use. Such designs require torque-limiter retrofits, even if existing assembly geometry is tight. Making the issue more challenging is that end users often want a solution […]
Nexen BD caliper brakes offer higher clamping force
Nexen Group, Inc. offers three models of BD (brute disk) caliper brakes; air actuated, spring actuated/air released, and spring actuated/hydraulically released. The innovative BD design uses arms to provide a mechanical advantage, allowing higher clamping force. (Stopping power can be multiplied by installing additional caliper brakes on each disc.) Torque ranges from 8,000 to 23,000 […]
New CS Electromagnetic actuated clutches from Miki Pulley
Miki Pulley’s CS Electromagnetic Actuated Clutches are durable, versatile and have excellent torque transmission features. CS Clutches provide an efficient connection between a motor and a load providing low inertia, minimal drag and very quiet operation. They function utilizing the magnetic force generated by the energized coil providing engagement of input and output members of the clutch. […]
What are common modes of industrial clutch and brake engagement?
Key parameters dictate which clutches and brakes are suitable for a given application: The first parameter is the mode of motion and whether the axis needs a brake or clutch. Clutches generally bridge moving machine sections to shape relative motion, while brakes’ main job is to stop and hold rotating elements. Several design variations exist, […]
What are overrunning clutches?
Overrunning clutches, sometimes called freewheel clutches, are used to freewheel in one direction while driving in another direction of rotation. When the driven shaft is rotating faster than the driveshaft, the clutch mechanically disconnects the driveshaft from the driven shaft. They are used in heavy-duty applications, such as agriculture, mining, aerospace, industrial metal processing, indexing, […]
