PNEUMATIC BRAKE-CLUTCH WITHOUT ROTARY AIR INTAKE Type NEF Description The pneumatic brake-clutch EIDE type NEF it is a compact unit composed of pneumatic clutch and opposed brake acting by spring reaction. The drive cylinder is fed radially with compressed air at a nominal pressure of 5’5 bars. The air consumption is minimum, the air chamber provided with chromeplated and lapped liners providing an optimum efficiency. The driving part is linked to the unit through two ball bearings, it is provided with a cylindrical area with axial threaded bores for an easy coupling of a pinion or a pulley (see assembly examples const. 1.1) or of an elastic coupling to be adapted between two shafts in line (const. 1.2). If we adjust the air pressure correctly, we shall be able to control the acceleration time of the machine as well as to obtain a limitation of the transmitted torque with the corresponding safety for the rest of the mechanisms. Due to its structure, it does not require any special maintenance, the friction linings work at a very low specific pressure, therefore their wear is minimum. The ball bearings are greased in the factory and do not require any further care. ASSEMBLY EXAMPLES Construction 1.1 (2) Adaptation a chain pinion Quick exhaust with silencer (1) To the electric control (1) Only in assemblies that require a quicker brake response. (2) Support for locking the turning reaction caused by braking.
