CPC Subclass Not Allocatable
F16D COUPLINGS FOR TRANSMITTING ROTATION; CLUTCHES; BRAKES
Description
F16D encompasses mechanical devices that connect rotating shafts, control torque transmission, and dissipate rotational energy in machinery. This subclass covers rigid and flexible couplings, universal joints, clutches for engaging/disengaging drive trains, and braking systems that arrest or regulate motion. Applications span automotive transmissions, industrial machinery, power transmission equipment, and mechanical control systems. Adjacent classes F16C (bearing and lubrication) and F16G (springs) address related but distinct mechanical functions.
