F16F15/22 - CPC Classification

Classification description:

Suppression of vibrations in systems ; Means or arrangements for avoiding or reducing out-of-balance forces, e.g. due to motion Compensation of inertia forces

Sub-classes:

F16F15/223 » {Use of systems involving rotary unbalanced masses where the phase-angle of masses mounted on counter-rotating shafts can be varied } 25
F16F15/226 » {in star engine arrangements} 0
F16F15/24 » of crankshaft systems by particular disposition of cranks, pistons, or the like 22
F16F15/26 » of crankshaft systems using solid masses, other than the ordinary pistons, moving with the system, {i.e. masses connected through a kinematic mechanism or gear system } 55
