NEF pneumatic clutch-brake is a compact unit with pneumatic clutch and antagonistic spring reaction brake. The drive cylinder is supplied radially with compressed air at a nominal pressure of 5.5 bar.
The conductive part is incorporated into the assembly by means of 2 bearings, it has a cylindrical area with axial threaded holes to facilitate the incorporation of a pinion or pulley or an elastic coupling for adaptation between 2 axes in line.
Properly regulating the air pressure we will obtain control over the acceleration time of the machine and also a limitation of the transmitted torque with the corresponding safety for the rest of the mechanism.
For a quick response, it is advisable to mount the solenoid valve directly on the clutch-brake body, which makes it possible to eliminate the quick exhaust valve.
The usual mounting is through a pulley, chain disc or drive sprocket onto a driven shaft. The brake is applied to the driven shaft.
