The invention discloses a switchable rack and pinion inertial capacity, which comprises an electromagnetic induction coil mechanism, a switchable inertial capacity and a casing. The electromagnetic induction coil mechanism includes a power generator, a solenoid with an electromagnet core and several coils. The switchable inertia includes a rack, seven large and small gears, three connecting rods, two bearings, a sleeve, two clutches, a flywheel and a switching lever with a magnet on the top. The first gear is coaxially connected with the second gear, the third gear, the fourth gear and the sixth gear are coaxially connected, the fifth gear and the seventh gear are coaxially connected with the flywheel through bearings, and the fourth gear is connected with the fifth gear meshing, the sixth gear meshes with the seventh gear, the rack meshes with the first gear, and the switching lever is connected with the third connecting rod through the sleeve. The size of the components of the invention can be large or small, and the installation is convenient, which solves the problem that the inertia capacity of the traditional rack and pinion cannot be switched due to the fixed structure.
Description
technical field [0001] The invention belongs to the field of mechanical vibration control, in particular to a switchable rack and pinion inertial capacity. Background technique [0002] Inertia is a double-terminal mechanical element in which the force acting on two endpoints is proportional to the relative acceleration of the two endpoints. The proportional coefficient is a constant, called inertial capacity, in kilograms. [0003] Inertia is mainly used for structural vibration reduction, dynamic vibration absorption and mass replacement. At present, it can be used for vehicle vibration reduction, fan vibration reduction, building vibration reduction, etc. In vehicle vibration reduction, inertia is mainly used to improve vehicle ride comfort, suspension travel and tire dynamic load performance; Vibration centering is mainly used to slow down the impact of earthquakes on buildings. [0004] The proposal of inertial capacity enriches the number of mechanical components an...
